The Four Horsemen - Signs of Incoming Crashes, and things.

Hey y'all! I'm going to keep this brief, but I was asked by Mr. October to post this, since I briefly described this on a discord we're both in. I do a ton of market analysis, mostly on alternative data, so I don't have cool superpowers potentially, but I do fancy myself a good trendspotter.
I wanted to share what I call my Four Horseman metric in brief, and I will fill it in more later when I get back/free from the clutches of homework.
The Four Horsemen:
  1. Rapid plunge in BTC/USD - This is an interesting metric, and makes sense if you understand that BTC has evolved from a hedge to a speculation play, which is why it arguably moves in lockstep with SPY most days. However, an interesting property I and many others have noticed is BTC seems to be a leading indicator of market movements, and rapid climbs/plunges tend to signal an incoming correction. See the chart on September 2nd, 2020 for an example.
  2. NOPE_MAD >= 3 End of Day: NOPE, or Net Option Pricing Effect, in principle looks at how dominant options flow trading volume is on the market compared to the more conventional shares volume. When the NOPE_MAD (median absolute deviation) compared to the previous 30 days is 3 deviations higher than normal, this means a red day the next day about 88% of the time (backtested to Mar 2019). You can check NOPE_MAD intraday here - https://thenope.info/nope/default/charts/SPY/2020-10-13 (the URL changes per day, so tomorrow will be 2020-10-14)
  3. The VIX rising with SPY - This usually is part of the parabolic phase, and means a metric fuck ton of calls are being written, which is pushing up option prices across the board. Usually VIX is a measure of downies-volatility, so when it and SPY both go up, it's a Very Bad Thing. Also see September 2nd, 2020.
  4. Small Tech/Caps Leading Big Tech/Caps - This is a more interesting metric, and only makes sense when you understand what causes a Minsky Moment style correction (irrational exuberance). In a stable market, big caps tend to act as a source of strength/safe harbor, and when small caps are leading, this tends to signal intense bull mania, which usually precedes a correction.
Honorable Mentions:
  1. Microsoft going up parabolically - Microsoft is our favorite boomer stock for a reason - it is much more stable than AMZN or AAPL, and doesn't like large movements. I noticed anecdotally this year that right before all the big tech corrections (3-5 days out) MSFT goes up exponentially, often more than the rest of the market, because smart money is looking for safe harbor.
I'd be happy to answer any questions later!

Edit: Wanted to add some stuff given the comments below.
  1. I did not write this to predict a crash based on today's behavior, but to generally inform about a metric I use to detect Minsky Moment style crashes. For more info on that - https://en.wikipedia.org/wiki/Minsky_moment
  2. Lots of these indicators are new, and due in large part due to the relative fuckiness of the current market. Bitcoin and SPY did not track until this year, and I only noticed the Microsoft effect I mentioned since about 6/5 onwards. This likely also happens in other boomesafe stocks, but MSFT is by far my largest active trading position, hence why I noticed it.
  3. I will be adding a post soon specifically dedicated to the interpretation of NOPE and NOPE_MAD.

Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Where can I spend bitcoins?

Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.

Merchant Resources

There are several benefits to accepting bitcoin as a payment option if you are a merchant;
If you are interested in accepting bitcoin as a payment method, there are several options available;

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.

Unit Symbol Value Info
bitcoin BTC 1 bitcoin one bitcoin is equal to 100 million satoshis
millibitcoin mBTC 1,000 per bitcoin used as default unit in recent Electrum wallet releases
bit bit 1,000,000 per bitcoin colloquial "slang" term for microbitcoin (μBTC)
satoshi sat 100,000,000 per bitcoin smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Public Proposal TL;DR:

Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and posts per Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625.
Watch Joe walk through the entire proposal and answer questions on YouTube.
This proposal is also available on the Dragonchain blog.

Hello Reddit and Ethereum community!

I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale.
For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube.
We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.

Executive summary

Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.

Response and PoC

In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.

Live Demo

A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks.
24 hours in 4 minutes (YouTube):
24 hours in 4 minutes
The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period.
Tooling to reproduce our demo is available here:
https://github.com/dragonchain/spirit-bomb

Source Code

Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.

Scaling

How it works & scales

Architectural Scaling

Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired.
Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.

Economic Scaling

An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity.
TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block.
TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.

Scaled Deployment

Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain.
With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times.
We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment.
Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.

Flexibility in Scaling

Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems.
We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
  • LBRY - To allow users to deploy content natively to LBRY
  • MakerDAO to allow users to lend small amounts backed by their Reddit community points.
  • STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.

Cost

Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction.
Dragonchain Fees Table

Getting Started

How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node.
Getting started is easy...
  1. Download Dragonchain’s dctl
  2. Input three commands into a terminal
  3. Build an image
  4. Run it
More information can be found in our Get started documents.

Architecture
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain.
Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain.
After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks.
Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.

API Documentation

APIs (on chain & off)

SDK Source

Nobody’s Perfect

Known issues or tradeoffs
  • Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
  • While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
  • Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.

Costs and resources

Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD.
For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments.
Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.

Requirements

Scaling

This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users.
Over a 5 day period, your scaling PoC should be able to handle:
*100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes.
Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum.
Reddit Scaling on Ethereum

Decentralization

Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
  • Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
  • Operational multi-cloud
  • Operational on-premises capabilities
  • Operational deployment to any datacenter
  • Over 700 independent Community Verification Nodes with proof of ownership
  • Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)

Usability Scaling solutions should have a simple end user experience.

Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node.
Examples:

Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.

Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users.
All of Reddit's Transactions on Blockchain (month)
Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees.
Reddit Internal Token Transaction Fees

Reddit Ethereum Token Transaction Fees
When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
  1. Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
  2. Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
  3. In a combination of the above, customers could cover aggregated fees.
  4. Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.

Bonus Points

Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here.
Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here.
In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here.
A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.

Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.

Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.

Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible
APIs should be well documented and stable

Documentation should be clear and complete
For full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.

Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected.
Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.

Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!

TIME

Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.

Dragon Den

Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR.
Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.

Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.

Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.

Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw

Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.

A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.

Bonus points
Public, third-party implementation review available or in progress
See above

Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.

Other Considerations

Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.

One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).

Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).

Conclusion

Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!

Disney Releases Blockchain Platform as Open Source

The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group.
https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html

Open Source

In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney.
Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
  • Obtain VP support and approval for the release
  • Verify ownership of the software to be released
  • Verify that no proprietary content would be released
  • Convince the organization that there was a value to the open source community
  • Convince the organization that there was a value to Disney
  • Offer the plan for ongoing maintenance of the project outside of Disney
  • Itemize competing projects
  • Verify no conflict of interest
  • Preferred license
  • Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
  • Obtain legal approval
  • Approval from corporate, parks, and other business units
  • Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
  • Trademark searches conducted for the selected name Dragonchain
  • Obtain IT security approval
  • Manual review of OSS components conducted
  • OWASP Dependency and Vulnerability Check Conducted
  • Obtain technical (software) approval
  • Offer management, process, and financial plans for the maintenance of the project.
  • Meet list of items to be addressed before release
  • Remove all Disney project references and scripts
  • Create a public distribution list for email communications
  • Remove Roets’ direct and internal contact information
  • Create public Slack channel and move from Disney slack channels
  • Create proper labels for issue tracking
  • Rename internal private Github repository
  • Add informative description to Github page
  • Expand README.md with more specific information
  • Add information beyond current “Blockchains are Magic”
  • Add getting started sections and info on cloning/forking the project
  • Add installation details
  • Add uninstall process
  • Add unit, functional, and integration test information
  • Detail how to contribute and get involved
  • Describe the git workflow that the project will use
  • Move to public, non-Disney git repository (Github or Bitbucket)
  • Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney.
The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

https://preview.redd.it/rqt2dldyg8e51.jpg?width=1044&format=pjpg&auto=webp&s=777ae9d4fbbb54c3540682b72700fc4ba3de0a44
We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.

Solutions

Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
  1. Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer.
  2. The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds.
  3. Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability.

Syscoin + Matic Integration

Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.

Proving Performance & Cost Savings

Our POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.
Addresses used: 100,014

It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.

Cost Savings

Total cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

Developer & User Diligence

Trade-off

The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.

Cost

Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.

Z-DAG

Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).

Benefits

  • Unique fee-market that is more efficient for microtransaction redemption and settlement
  • Uses decentralized means to enable tokens with value transfer scalability that is comparable or exceeds that of credit card networks
  • Provides high throughput and secure fulfillment even if blocks are full
  • Probabilistic and interactive
  • 99.9999% security assurance within 10 seconds
  • Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain
  • Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus

Z-DAG White Paper
Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana

Trade-off

Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.

Syscoin Specs

Syscoin 3.0 White Paper
(4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)
  • 16MB block bandwidth per minute assuming segwit witness carrying transactions, and transactions ~200 bytes on average
  • SHA256 merge mined with Bitcoin
  • UTXO asset layer, with base Syscoin layer sharing identical security policies as Bitcoin Core
  • Z-DAG on asset layer, bridge to Ethereum on asset layer
  • On-chain scaling with prospect of enabling enterprise grade reliable trustless payment processing with on/offchain hybrid solution
  • Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers.
  • Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization.
  • Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this.

Wallets

Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask.
Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2.
Current supported wallets
Syscoin Spark Desktop
Syscoin-Qt

Explorers

Mainnet: https://sys1.bcfn.ca (Blockbook)

Thank you for close consideration of our proposal. We look forward to feedback, and to working with the Reddit community to implement an ideal solution using Syscoin Platform!

Why i’m bullish on Zilliqa (long read)

Edit: TL;DR added in the comments
 
Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
 
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction
 
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
 
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
 
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
 
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
 
Decentralisation
 
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. The faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time-stamped so you’ll start right away with a platform introduction, roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
 
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships
 
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!

Test results TkeyNet, release date, and the opening of an office in the UK.

https://preview.redd.it/o29r0qu664j51.png?width=700&format=png&auto=webp&s=b34a6841ca97bbd70c9a23fe5ed83813d5f513d1
Hello everyone! Today we will talk about the results of the development of the TkeyNet system and related products, as well as share the test results and release date.
To date, the Protocol has fully debugged. The process of debugging the TkeyNet system is moving with decisive steps — 94.7% of testing of all the functions that TkeyNet includes has completed.
During the tests, the following properties and functions tested with different scenarios:
  • Atomic exchanges;
  • Security;
  • Validation;
  • Interaction of the Protocol with SQLite and PostgreSQL databases;
  • Consensus;
  • Modules for financial institutions;
  • Data exchange in the network;
  • Synchronization;
  • The monitoring system of balance;
  • Transactions that include trades;
  • API;
  • TkeyIndex;
  • TkeyConnect.
Documentation for the TkeyNet system will release on the website tkey.org as well as reviews of the system TkeyNet will be published in the company’s blog.
Back-end TkeyNet developed in the C++ and C) programming languages, to improve performance, some of the code written in C.
The C programming language is the world’s fastest high-level programming language. It is called a high-level assembler, but unlike an assembler, code on it can be compile without changes on any device.
The specified stack is selected to meet the stringent requirements of the financial sector: enhanced security, scalability, and the ability of the system to work 24/7/365. The TkeyNet system is adapted to the world standards: ISO, ISIN.

https://preview.redd.it/x9g2rlz864j51.png?width=700&format=png&auto=webp&s=b2cf80ee5cd722abdb306803d6454e2afde899b0
TkeyNet supports the structured query language and interacts with flexible SQLite and PostgreSQL databases.
PostgreSQL complies with ANSI/ISO SQL standards, and unlike other DBMSs, it has object-oriented functionality, including full support for the ACID concept. An SQLite was selected to improve the speed and performance of operations. SQLite will also serve as an excellent solution for mobile applications that will be created based on TkeyNet.
PostgreSQL is the most advanced RDBMS, focusing primarily on full compliance with standards and extensibility.
During this period, we also completed work on a powerful API. The API is designed for organizations and developers to use the full power of TkeyNet in individual solutions. Software developers, whether mobile apps or local software, will get APIs and client libraries that will simplify the interaction of the corporate market with TkeyNet.
The API provides guaranteed availability, scalable volumes, and responds within milliseconds.

Test results: transaction and operation speed in TkeyNet

To date, testing shows excellent results on the speed of payments made via TkeyNet.
Last week’s results: unlike the first Protocol, where it took at least 10 minutes to validate a transaction, payment transactions in TkeyNet processed in 25 seconds without losing security properties. Performance improved by 2400% compared to Core 1.0

The block generation time in Core 1.0 is at least 10 minutes, and in TkeyNet — 25 seconds according to the test results.
If it took at least 10 minutes to confirm a block, and sometimes it took two or more hours, in TkeyNet developers achieved a stable indicator of 25 seconds without losing security properties.
To achieve our goal of launching the Protocol — we identify possible changes, theorize solutions, model proposals, and test our theories in practice. This process involves a lot of internal discussions and collaboration with external parties who provide feedback on the operation of a particular module, and the entire system as a whole.
Before the launch of TkeyNet, work will carry out to optimize and improve performance. The team plans to increase its performance indicators by 6000% compared to Core 1.0.

The Core 1.0 block generation time is 10 minutes. TkeyNet test network — 25 seconds. TkeyNet main network-up to 10 seconds.
To do this, we will work with individual modules and libraries of databases, transactions, and consensus. The goal for developers is to process payment transactions for up to 10 seconds at most.
The process secure in the logic of consensus, which solves a complex problem in a matter of seconds.

High throughput rates of the TkeyNet Protocol. B2B & B2C sectors.

To meet the needs of companies, startups, and corporations, — TkeyNet responds with fast processing of trades*.
Payment transactions — exchange of currency or shares, exchange operations, interbank settlements, etc.
For a better understanding, let’s analyze the obtained characteristics at the time of testing TkeyNet:

https://preview.redd.it/t31c3kih64j51.png?width=466&format=png&auto=webp&s=daad005d8cd5066e9d3cb67e9f147d0a7b362d97
Results: 1,225,000 trades per block.

The scaling of the TkeyNet system

The TkeyNet system is easily scalable by increasing the RAM and CPU parameters. We have launched three nodes on powerful servers with the following characteristics:
  • CPU: 72 Core.
  • RAM: 144 Gb.
  • SSD: 120 Gb.
Transaction throughput increased 2.8 times to ≈3,430,000 transactions per block.

Vertical scaling

Unlike Bitcoin and other blockchain systems, where increasing the power of the miner’s hardware does not lead to an increase in network bandwidth.
Usually in such networks, increasing the power is a direct necessity, otherwise, transactions will not take place at all or will take hours, or even days. Because of what actually appears “manipulation of miners” and various types of network attacks.
On practice in such networks, increasing power is a direct necessity otherwise, transactions will not take place at all or will take hours or even days. Therefore of what appears “manipulation of miners” and various types of network attacks.
TkeyNet uses vertical scaling. With increasing node capacity, the throughput of the entire TkeyNet system increases. It turns out that regardless of the number and power of nodes, transactions will take place in 25 seconds, and with increasing power nodes — the number of processed transactions will grow.
As we said above, our developers are working to improve these indicators, where the block validation time will take no more than 10 seconds. Transactions will take place for 1 second to 10 seconds maximum. Also, this parameter significantly increases the volume of trades conducted via TkeyNet.

Front-end. Graphical user interface.


https://preview.redd.it/wrjfa95n64j51.png?width=700&format=png&auto=webp&s=a5137fac7774864fab431fdd7ac51c73ffca3075
During August, the web products team continues working on secure wallets and a blockchain Explorer. The new software is under development, but it has already come a long way from layouts and graphic design and is ready to move to the stage of connecting the TkeyNet back-end with native products. If everything is in the final stage on the back-end side, then the client part (front-end*) needs time to complete debugging. We needed to design applications per best security practices.
\The Front-end developer creates the user interface.* Testing of blockchain applications is not much different from testing regular applications and resembles functional testing of a payment system. Test cases include checking the balance, fields, transaction statuses, and so on.
Also, we conduct continuous testing during development, taking into account the severity and scale of the TkeyNet system that will be used by organizations, corporations, and users, respectively. According to the results of testing and a meeting of the development team, the launch of TkeyNet is agreed for September 25–mid-October, possibly earlier.

Tarkov Overview - What is Escape from Tarkov?

Escape from Tarkov is a tactical, realistic, FPS with MMO elements developed by Battlestate Games. It is currently in closed Beta. The game features several maps in which your primary character, your PMC, goes into Raids in order to find and salvage loot and useful equipment to survive and thrive in Tarkov. Death is very punishing in Tarkov. If you die you lose everything you had on you when you die (with the exception of what's inside your Container and your melee weapon) including any equipment you brought with you or what you found inside the Raid.
Enemies can be players (PMCs) or Scavengers ('Scavs') that are either controlled by AI or by players. Unlike many shooters, AI enemies in Tarkov are deadly - they can and will kill you on sight. They have recently been upgraded to act more intelligently, shoot more accurately, and react to situations on the map, such as investigating noise of gunfire or searching. It features beautiful and immersive environments, intricate and in-depth weapon modification system, a complex health system, dynamic and specific loot placement, and multiple options for engagement. Do you want to play slow and stealthy, to avoid fights, or set up a deadly ambush on an unwary foe? Or do you prefer raw combat, where only your quick wit, placements of shots, and tenaciousness determines who gets out alive? It's your Tarkov. You make the rules.

Tarkov Resources - Useful links

I take no credit or responsibility for any of the content in these links. To the best of my knowledge, these are updated consistently and are accurate, but user beware.

Quick-Reference Ammo Chart

An updated ammo chart can be found on the wiki.

Tarkov Wiki

Absolutely fantastic resource. You can visit them here.
It is a massive collection of everything that we players have been able to find.
They contain trades, user-created maps, lists of ammo, parts, weapons, loot, etc. If it's in the game, it's on the Wiki, somewhere.
I highly recommend opening the wiki page for the Map that you plan on raiding in.

Offline Raids - Player Practice

Offline raids is a feature added for testing and learning purposes for both new and veteran players alike. It is an incredibly useful tool.
In an offline raid, your progress is not saved. This means you don't keep anything you find, keep any experience 'earned' if you successfully extract, or lose any gear when/if you die. To access OFFLINE Raids, head into a Raid normally until you see this screen. Then Check the box indicating that you want to do an OFFLINE raid and you're good to go! You even have a choice on whether or not to add AI. You can also control how many AI enemies spawn, fewer than normal or a great deal more! You can even make Scavs fight each other. (Framerates beware.)
You can control how many scavs spawn (if any) as well as a number of other paramaters. New players should use offline raids as a tool to practice shooting, controls, movement, etc.

Tarkov's Maps

Tarkov features several maps - ranging from wide, beautiful vistas to ruined factory districts, to an abandoned laboratory where illegal experiments were being conducted. It is important to learn the maps you intend to play. In order to keep your gear, you must 'extract' at one of your designated exfiltration points. Not all extracts will be active every game, and some are conditional.

To see what extracts are available to you, double tap 'O' to show raid time and your exfils. If it has a ???? it might not be open.

Factory

Gate 3 Extract
A small, fast-paced map that was primarily created for PvP. Scavs spawn in all the time. Very close quarters, shotguns and SMGs tend to dominate here. PMCs can only access one Exit (Gate 3) without the Factory Exit Key. Good place to go if you need PMC kills as action is pretty much guaranteed. It is recommended NOT to bring in a lot of gear to Factory until you are experienced.
Factory Map in PvP is best played in Duos - due to the layout of the map, a Maximum of 6 PMCs may be present in the game. Due to the split spawn points, you effectively have 'sides' that have up to 3 spawn locations that are close together. This is why it is recommended to secure/scout enemy spawn locations. If you go in with a Duo, you at max have 2 players on your side for an even 2v2, and if played smartly you can eliminate them and know your 'side' is secure from aggression for the time being.
Upon loading in, scavs usually take a couple minutes to spawn, though this depends on the server in question and isn't super reliable. For new players, the best loadout in Factory is going to be a MP-153 Loadout - using just an MBSS (or similar bag) and ammo in your pocket to fight other players and Scavs. Scavs will often spawn with AKs and other 'vendorable' weapons, so is a good source of income.
Factory is also one of the best maps to Scav into, as Scavs can typically avoid the Exit camping strategy employed by a lot of weaker or newer players in order to secure gear, because they typically have extra exfiltrations whereas PMCs without the Factory Exit Key are stuck using Gate 3.
If you go in with a modicum of gear, it is recommended to keep at least a flashbang (Zarya) in your container. This will allow you to quickly slot it into an empty chest rig or pocket so you can throw it into the exit door, this will flash enemies and is cheap to do - the one time you survive because you flashed the 3 exit campers using shotguns will make this strategy extremely valuable.

Customs

Extract map
A fairly large map that was recently expanded and is expected to receive an overhaul within a patch or two, due to the choke point design of the map. Essentially, players spawn either on 'warehouse' or 'boiler (stacks)' side. If you see a large red warehouse ('big red') near you (Customs Warehouse), then you spawned on the warehouse side. If you don't, you likely spawned near Boiler side. Players can also spawn in several places in the woods North of boilers.
This map has the most quests in the game. Geared players often come to customs to challenge other squads over Dorm loot and to fight a Scav boss. New players are usually trying to do one of several early quests, such as ‘Debut’ which tasks them with killing 5 scavs on Customs and acquiring 2 MR-133 shotguns (pump shotties) from their corpses. Construction is also a popular hotspot as it has a lot of scav spawns as well as the location for the Bronze Pocketwatch, which is Prapor’s second quest.
Customs itself does not offer very much loot on average. There are several spots which can contain decent, but the vast majority is located in a couple different locations.
Dorms is the best loot location for Customs. It has two sets, 2 story and 3 story dorms. They each have their own sections of good loot, but the best is considered to be 3 story dorms, due to the presence of the Marked Room. The marked room requires a marked key to open, and has a good chance to spawn rare loot, such as keytools, documents cases, weapons cases, and high-end weapons. Due to the nature of the high value of this room, it’s almost always contested and it’s one of the best rooms in the game to farm, albeit with difficulty to successfully extract with the loot found. Note, though the key required has a maximum amount of uses, it is a fairly cheap key, and worth buying if you like to run customs and go to Dorms.
Dorms also has a ton of early quests (Operation Aquarius, for one) with some keys being valuable to use, but most dorms keys aren’t worth that much on the market. There’s too many to list here, but make sure to check the Map Keys and You at the top of the guide to determine what the value of a particular key is.
Checkpoint (Military Checkpoint) is also a decent loot spot, though not nearly as good as Dorms. If you have the key, it has a grenade box and 2 ammo boxes which can spawn good ammo. The jacket in the blue car also can spawn good medical keys as well as medical items. It is very close to the gas station, so I’ll include that here as well.
The Gas Station is one of the possible spawn locations for the scav boss. It has loose food items, a weapon box in the side room, with two keyed rooms leading to a safe and a med bag and box. Also contains a couple registers and food spawns on the floor. The emercom key can spawn on the seat in the ambulance out front.
North of the gas station is the Antenna, which contains 3 weapon boxes, a tool box, and a med bag. Possible location for scav boss spawn, albeit rarely, and also spawns regular scavs, like checkpoint and gas station.
Beyond that, there’s scattered loot around the map in different places, but usually not enough to warrant going out of your way for. There’s also scav caches, mostly around the middle road outside construction and around the boiler area.
The scav boss for customs is 'Reshala.’ He has 5 guards that have above-average gear and can be tough to deal with solo. The guards tend to be more aggressive than normal scavs, so they can be a lot to handle but are vulnerable to fragmentation grenades or flashbangs due to their close proximity to one another. Reshala himself has a good chance to have one or more bitcoin in his pockets, as well as his unique Golden TT, which is required for a Jaegar quest and used in conjunction with other Golden TT's to purchase a Tactec, good plate carrier. Reshala may spawn either Dorms (either bldg), New Gas Station, or rarely the tower north of the gas station. Scav bosses are dangerous enemies with escorts that have above-average loot (sometimes great loot) and are hostile to everyone, Including player scavs. Scav guards will approach a player scav and basically tell them to leave the area, and if they walk closer towards the scav boss they turn hostile.
The ‘official’ spawn rate for Reshala is 35%.

Woods

Woods Map with Exfil
A very large map that is mostly just a large forest, with the occasional bunker, and the Lumber Mill in the center. The Lumber Mill is the primary point of interest, as it contains a couple quest locations and is the primary location to farm Scavs, as Scavs killed on woods are a good source of end-game keys that are hard to find.
Since the map is so large and open, sniper rifles with scopes usually reign king here. You will see a lot of players with Mosin rifles as they are a cheap way to train the Sniper skill (for a quest later on) and are capable of killing geared players and scavs alike.
Overall, not usually very populated. An early quest from Prapor sends you here to kill a number of Scavs. A good map to learn the game, as although the loot is not fantastic, you can get experience with how the game runs and operates while fighting AI and possibly getting lucky with a key find off a scav.
As of .12, Woods now houses a Scav boss that acts as a Sniper scav. He is incredibly dangerous and usually carries a tricked-out SVDS. The 7.62x54 caliber is not to be underestimated. That caliber can and will wreck your shit through what most players are capable of wearing, especially early on in a wipe. He may also carry an AK-105, so he's going to be dangerous at both short and long ranges.
He has two guards, and he typically patrols the area around the Sawmill, and carries a key to a cache nearby full of goodies. His key is part of a quest for Jaegar.
Woods also has two bunkers, one of them being an extract and requiring a key. Both bunkers have some moderate loot in them, thus worth visiting, though not necessarily worth going out of your way for them. Several quests occur around the sawmill area, which contains a good couple keys that can spawn.

Shoreline

Shoreline Map, with Loot, Exfil, etc
A very large map, notorious for its FPS hit. Generally speaking, one of the better maps for loot. The primary point of interest is the Resort, but scavs spawn there, and is primarily occupied by hatchlings (players only with hatchet, ie melee weapon) and geared players. Resort has great loot, but requires keys to access most of it.
A great map to learn though from new players as the outskirts still contains plenty of loot and combat opportunities with AI scavs. You can hit Villa, Scav Island, Weather station, Docks, etc and come out with a backpack full of valuable gear fairly easily. The Village (Not to be confused with villa) contains a lot of toolboxes which can contain lots of parts used to upgrade your Hideout.
Location of many quests, including a large quest chain where players are required to kill many, many, scavs on Shoreline. For this and other reasons, probably the best map for new players to learn the game with.
A good loot route is to hit the village (caches in it), scav island (2 med bags, 2 toolboxes, 2 weapon boxes, 1 cache), burning gas station (weapon boxes and a safe), pier (potential extract, 2 pcs 2 safes and lots of filing cabinets), and weather station. Scavs may spawn around these areas, but most players just head straight for resort anyway, so you are much less likely to encounter them, especially if you avoid Mylta power (most players hit it on the way to or leaving from the resort). Excellent route as a player scav as well.

Interchange

Detailed map
Great, great loot area, but very complex map. Old computers might face unique struggles with this map. Features a mostly-binary exfil system like Shoreline, but.. kinda worse. Exfil camping is fairly common on this map, but usually avoidable. Huge map with multiple floors and many many different stores. Communication with teammates is a challenge on this map, but the map is also fantastically detailed.
This map features a lot of loot that depends on the kind of store you're in. It's a great place to farm rare barter materials which are valuable to sell on the Flea market or to use for quests or for hideout upgrades. An early quest (from Ragman) sends you here to kill a large amount of Scavs. I'd recommend getting Ragman to level 2 and accepting his quest asap when going to Interchange, as getting this quest done can take a while as it is and you want all scav kills to count towards progress.
Both the tech stores (Techlight, Techxo, Rasmussen) and department stores (Groshan, Idea, OLI) are the primary places to hit. There’s also Kiba (weapons store) as well as Emercom and Mantis. Players have different strategies, but this map is unique in the sense that it really rewards exploring. Most stores will have things you can grab that are worth quite a bit but are often overlooked. Very popular place to go in as a Player Scav.

Reserve

Brand new map, chock full of loot. Has more complex extracts than other maps, save for Labs. Excellent place to farm rare barter items, computer parts, and especially military hardware. PMCs have limited extracts, most being conditional, and the ones that aren’t require activation of ‘power’ to turn on the extract, which alerts the map the extract has been opened and can spawn Raiders (more on them below.)
Additionally, has a scav boss by the name of Glukhar, who has multiple heavily armed guards. He has multiple spawn locations and can arrive with the train.

The Lab ('Labs')

Here's a map.
DISCLAIMER: Labs, like much of Tarkov, is under constant development, so issues may be fixed or created without warning. Always check patch notes!
Labs is a very complex map compared to the rest of Tarkov. There is a great deal more exfiltrations but many of them have requirements or a sequence of events needed to be able to extract from them. It is recommended to read the Tarkov Wiki on Labs before raiding there.

LABS IS NOT LIKE OTHER MAPS. READ THIS SECTION CAREFULLY.

Labs is a lucrative end-game raid location, comparable to 'dungeons' in other games. They are populated by tougher enemies that give greater rewards. In order to go to labs, you need to acquire a keycard, this functions like mechanical keys but instead of opening a door, they unlock your ability to select Labs for a raid.
They may be found in-raid in various locations, most notably in scavs backpacks, pockets, and in filing cabinets. They may be purchased from Therapist at LL4 for 189K Roubles. Labs are populated by a unique kind of AI enemy, Raiders.

Raiders

Raiders are the Labs form of Scavs, or AI enemies. However, unlike other maps, they cannot contain player Scavs. Raiders have a much tougher than your average scav, they are capable of advanced tactics (such as flanking) and throw grenades and use other consumables as a player would. Once 'locked' onto you, they are typically capable of killing you very quickly, even if you are wearing high-end armor.
In Tarkov, Raiders act like the avatars of Death. They are clad in USEC and BEAR equipment, as they are effectively AI PMCs. Many changes have been made to labs and specifically how Raider AI works and to prevent exploits to easily farm them as well as bugs where they could be deadlier than intended.
A general rule of thumb is not to fight Raiders directly. They can and WILL kill you. Raiders can spawn with 7N9, or 'big boy' ammo. This ammunition type is incredibly lethal to players, even those wearing the toughest armor. If you get shot in the head, doesn't matter what kind of helmet, face shield, killa helmet, etc you are wearing, you will almost certainly die.
Because Raiders are controlled by AI, they have zero ping. They may also end to immediately respond as if you were aggressive even if they did not originally know you were there - ESP Raiders effectively will prone and return fire even as you ADS and put them in your sights.
This is why engaging a Raider must be done very, very carefully. There are a few strategies that you may employ, most commonly some form of baiting them towards an area and then killing them when they arrive. Players may accomplish this by generating noise - gunfire, melee weapon hitting walls, crates, etc, player deaths, players Mumbling (F1 by default) can all attract Raiders to investigate your area.
Due to the high power of Raiders, players often go in with minimal loadouts and seek to avoid conflict with other players, especially geared ones. Most players avoid PvP in Labs, though a good portion of the playerbase thoroughly enjoys hunting down poorly-geared players after they kill a few Raiders for them.
As such, players will lay prone in a hallway, or crouch in a room, and attract Raiders to enter their domicile by opening the door, and immediately headshotting them. Few Raiders actually wear helmets (though some do) so most players specialize in 'flesh ammo' or, ammunition that foregoes armor penetration in favor of raw damage in order to kill Raiders more reliably, because Raiders have slightly higher head health than PMCs do.
Raiders spawn with a great variety of equipment, weapons, armor, and materials such as medication or hideout parts. They tend to have chest armor and may have different helmets. Their pockets can contain Labs keycards, morphine, Ifaks, cash, and other items. They're always worth checking.
Raiders are a good source of grenades, they will often have F-1's and Zarya's in their rig or pockets that you can use to fight off players and Raiders alike.
Recently, changes have been made to Labs to make them less profitable so that other maps are more appealing. The cost and rarity of keycards increased, as well as reducing the frequency that raiders spawn, so that they come in more infrequent groups but also tighter in formation, while also lowering the overall output of individual Raiders, so that they are less likely to have a bunch of extra materials, such as grenades and other items.
Experience Farming on Labs
Labs is one of the best places to farm experience in the entire game. Killing a Raider with a headshot awards 1100 Experience. This does not include any looting, inspection (searching bodies), examine, streak, or other experience.
Killing a large sequence of Raiders gives additional bonus experience in the form of Streak rewards, usually 100 bonus exp per additional kill.
Surviving the raid multiplies all of these sources of experience by 1.5x
Changes coming to Labs
Disclaimer: I am not a BSG developer or employee. This is what I have seen on this subreddit and heard elsewhere. Some might be purely rumor, but other points are confirmed by Nikita Labs is undergoing constant changes. Nikita and BSG take feedback seriously, and always consider what the players are telling them. It known that Labs will eventually be accessed via the Streets of Tarkov map, and will require you to enter that map, make it to the labs entrance, and then extract from Labs to return to Streets of Tarkov and exfil from there as well. This will likely add an additional layer of risk to being ambushed for your goodies along your way out, as well as punishing damage taken in labs more severely. Additionally, keycards will have a limited number of uses, and may open more than one room.
The full extent of the changes coming is not known.
Remember, you can load a map in OFFLINE mode to practice against bots or to learn the map without fear of losing gear.

Tarkov's Health System

Tarkov Wiki Article
Tarkov has a very advanced health system, and while it might seem overwhelming at first, you'll get the hang of it rather quickly. It features a very wide variety of effects and injury, including hydration, energy, blood pressure, blood loss, fractures, contusion, intoxication, exhaustion, tremors and more.
Not all of the Health System is implemented yet. Expect changes!
Your character (PMC, or otherwise) has a combined Health of 435. Each of his limbs have separate health. Taking damage to a limb that reduces it to 0 'blacks' that limb. Blacked limbs are a problem. They greatly impair the activities your PMC performs, and taking damage in a blacked limb amplifies the damage by a multiplier and spreads that damage among your other non-black limbs equally. You cannot heal a blacked limb without the use of a Surgical Kit.
Notes: Bloodloss applies damage to the affected limb and can be spread like other damage to a blacked limb. Treat immediately. Also causes significant dehydration! Bloodloss also helps level your Vitality skill, which in turn gives you experience towards your Health skill, which is necessary to reach level 2 of in order to improve your hideout.
Losing a limb applies additional effects. Fractures also apply these effects but not the damage amplification (Except for damage if running on fractured leg.) Fractures require specialized medical kits to heal.
Dehydration is what happens when your Hydration level reaches 0. You can view your Hydration level in your gear page, at the bottom left. Becoming dehydrated is extremely bad. You take constant damage. Taking dehydration damage can kill you if you have a black chest or head. Restoring hydration helps train Metabolism, which improves positive effects from food and drink.
Head/Chest: Bullet damage resulting in losing your head or chest is instant death. Note: Bloodloss resulting in your Head/Chest being black does not result in death, but any damage to them beyond that point will! A back chest will causes you to cough (much like your stomach!)
Painkillers: Prevents coughing that comes from your chest. Doesn't help otherwise.
Stomach: Massively increased rate of dehydration and energy loss. You must find liquids or exit the Raid soon. Additionally, your PMC will cough sputter loudly, attracting attention. A black stomach multiplies damage taken by 1.5 and redistributes that damage across your entire health pool.
Painkillers: Significantly reduces the frequency and volume of the coughs.
Arms: Makes activities like searching, reloading, etc, take additional time, as well as adding a sway, reducing accuracy. Arms have a .7x damage multiplier.
Painkillers: Reduces sway, removes debuff Pain.
Legs: Blacked legs cause your PMC to stumble and be unable to run. Blacked legs have a 1x damage multiplier.
Painkillers: Allows you to walk at full speed and to run.
WARNING: Running while your legs are blacked or fractured WILL DAMAGE YOU.
Health Items
Tarkov features many health items - 'Aid' items, which can be used to restore your characters health and to fix ailments or injuries he receives as the result of combat or mishaps. The two most important health conditions to consider are bloodloss and fractures, which have both been covered above. Some food items may have ancillary effects, such as losing hydration.
Since in the current patch the only ailments to worry about are bleeding and fractures, it changes which health items are most necessary. We'll go over them below.

Health Restoration

Medical Items on Wiki
AI-2 medkit
The newb's medical kit. You receive several of these when you start Tarkov - they'll already be in your stash. Available from Level I Therapist, they are cheap and effective way of healing early in the game. They will not stop bloodloss. Because of this, you also need to bring bandages or a higher-grade medical kit. Affectionately called 'little cheeses' by the Tarkov community. Using it takes 2 seconds, and because of how cheap it is, it's often brought in by higher level players to supplement their healing without draining their main kit (which is capable of healing bloodloss or sometimes fractures). Due to its short use time, it's often very useful during combat as you can take cover and quickly recover damage taken to a vital limb. They're also useful as you can buy them from Therapist to heal yourself if you died in a raid.
Bandages
The newb's bloodloss solution. Available from Therapist at Level I. A better version, the Army Bandage is available at Level II, after a quest. Mostly obsolete after unlocking the Car Medical kit, but some players value them due to the Car's overall low health pool. Activating takes 4 seconds, and removes bloodloss to one limb.
Splint
The newb's solution to fractures. Cheap, takes five seconds to use, and takes up 1 slot. Fractures are much more common this patch, due to them being added back in the game from standard bullet wounds, not just drops. Available from Therapist at Level I, no quest needed. Can be used to craft a Salewa.
Alu Splint
More advanced form of the normal split. Works the same, but has up to 5 uses. Recommended to carry in your container if possible, due to frequency of fractures from gunfire.
CMS (Compact Medical Surgery) Kit
New medical item added in .12, fantastic item. Allows you to perform field surgery, removing the black limb state and allowing you to heal it beyond 0 hp. Takes 16 seconds to use, and cannot be cancelled so make sure you are safe if you are using it! Will reduce the maximum health of the limb it's used on by 40-55%, but will effectively remove all negative effects incurred by having a black limb. Highly recommended to carry in your container for emergencies. Can be bartered from Jaeger LL1, and purchased for roubles LL2.
Surv12 field surgical kit
Same as the compact surgical kit, but takes 4 seconds longer, and the health penalty is reduces to 10-20% max health of the limb. Considering this kit is 1x3, taking up a huge amount of space, it's probably not worth using. It's just too large. Better this than nothing, though.
Car Medical Kit
The newb's first real medical solution. Available LL1 as a barter (2 Duct Tape) and available for Roubles after completing Therapist's second quest. Has a larger health pool than AI-2's (220, vs AI-2's 100), and removes bloodloss. Takes up a 1x2 slot, so requires to be placed in a tactical rig in order to be used effectively. Cheap and fairly efficient, takes a standard 4 seconds to use. Rendered effectively obsolete when the Salewa is unlocked.
Often kept in a player's secure container as a backup health pool, before IFAKs are unlocked.
Salewa
Good medkit for use in mid and end-game. Contains 400 total health and can remove bloodloss. More rouble efficient form of a healing due to its high health pool, costs 13k roubles. Same size as the Car medical kit, so requires a tactical rig to use effectively. Because Tarkov does not currently have effects like Toxication in the game at the moment, this kit is favored by most players who go into a raid with at least a moderate level of gear. With a high health pool and relatively low cost, it's also a more efficient way of healing damage sustained while in raids. Unlocked at Therapist Level II after completing a level 10 Prapor quest, Postman Pat Part II. Required as part of Therapist's first quest, Shortage. This makes Salewas very valuable early on in a wipe as it gatekeeps the rest of Therapist's quests, most of which occur on Customs early on. Can be crafted in your meds station with a painkiller, splint, and bandage.
IFAK
Fantastic medical kit, and is the one preferred by most players. Features 300 health and the ability to remove bloodloss and a host of other negative effects that are not yet implemented into the game. It does not, however, remove fractures. Taking up only a single slot, it is favored by players in all stages of gear, and it is recommend to carry one in your Secure Container in case of emergencies. Is available at Therapist Level II for a barter (Sugar + Sodium), and may be purchased for Roubles at Level III after completing Healthcare Privacy, Part I. It is a fairly expensive kit, but due to its durability, its small size, and ability to remove bloodloss, it is a very common medical item used by players of all levels. Can be crafted in Lvl 2 medstation.
Grizzly
The 'big daddy' medical kit, boasting an impressive total health resource of 1800. It is also a very large kit, taking up 4 slots (2x2) - in order to be able to use this quickly, it would require specialized tactical rigs that feature a 2x2 slot. It removes all negative effects (some costing HP resource), including fractures. Used by highly-geared players who intend on staying in raids for an extended period of time, or by players with additional Secure Container space available in case of emergencies. It is available for barter at Therapist Level II, and purchase at Therapist Level 4. Due to its price point from Therapist at just under 23k Roubles and its healthpool of 1800, it is by far the most efficient method of healing from raid damage, at a 1.3 roubles per health, dramatically lower than other options available. Can be crafted in Lvl 3 medstation.

Pain Management

Using any of these items results in your character being 'On Painkillers' which allows you to sprint on fractured and blacked legs, as well as reducing effects of fractures and blacked limbs, and removing the debuff Pain. Essentially, the only difference between most of these items are the speed of use, price, availability, and duration of the effect. Note that the Hideout has changed how some of these items are used, and because Tarkov is under constant development, it is very likely that these materials may be used to create higher-grade medkits or to upgrade your medstation. That being the case, it's best to hoard the unknown items for now as efficiently as possible until you know you don't need them.
Analgin Painkillers
The holy grail of pain medication. "Painkillers" have 4 total uses. The total duration is greater than Morphine and less risk of waste. Takes a short time to use, and is available from Therapist Level 1 for both barter and Roubles. Makes a loud, distinctive gulping noise. Can be used to craft Salewa kits.
Morphine
Quick application of painkillers. Favored by some highly geared players as it has greater usability in combat then it's typical counterpart, Painkillers. Has a longer duration, but only one use. It is required for a fairly early Therapist (and a late Peacekeeper) Quest, so it is recommend to hoard 10 of them, then sell the rest unless you intend on using them. They are worth a good amount to Therapist and take up little space so they are a valuable loot item. Available from Therapist for Roubles at Level 4, after completing Healthcare Privacy, Part 3.
Augmentin
Basically a cheaper Morphine. One use, 205s. Not recommended over Painkillers due to its cost. No current barter for this item, so usually it's just a fairly expensive, small loot item. Most likely a component of a medstation manufacturing process or upgrade. Keep it.
Ibuprofen
Powerful painkiller. Lasts 500 seconds and has 12 uses. This item is recommended as your long-term solution for painkillers. While it is valuable because it's used to trade for THICC items case, it's the cheapest component and is very useful as a painkiller. It has a long duration and a large amount of uses, so keep it in your container for use as a painkiller if your primary painkillers wear off. Don't use it completely up, though. Keep the 1/12 bottles for the trade.
Vaseline
Powerful medical item. Cannot be purchased from dealers. Has a maximum of 10 uses. Removes Pain, applies Painkillers for 500 seconds (8.3 minutes). Useful to keep in your container as an alternative to Painkillers, though it takes 6 seconds to use, which is longer than other painkillers. Used as part of a barter trade for the Medcase.
Golden Star Balm
Fairly useful medical item. It can remove Pain and Contusion (not a big deal of a debuff, goes away on its own shortly) and provides a small bonus to hydration and energy. It also removes toxication and Radiation exposure, both of which are not yet implemented into the game. Like Vaseline, has a maximum of 10 uses. Painkiller effect lasts for 10 minutes, and takes 7 seconds to apply. Recommended to take only if you are going on large maps and you have extra room in your container. Can be used with Ibuprofen and 5x Med parts to craft 7 Propital.
