Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

Gulden [NLG] - Constant development - In wallet Staking/Mining/Dex

Official Website / Official Slack
About Gulden:
How to setup a Witness (Staking) Gulden was founded in April 2014 based on the Litecoin codebase. In 2015 the Litecoin codebase is abandoned and Gulden switched to the Bitcoin codebase. After years of development it can be said that Gulden now has its own codebase. Gulden started with a 10% premine that was spent entirely on development. The current developments are now paid by part of the mining reward. The direction of the developments are determined by the Gulden advisory board (GAB). The GAB consists of 9 members and is elected each year from the members of the community. Anyone can stand for election. Voting for candidates is recorded and done through the Gulden blockchain. Gulden would like to become a generally accepted means of payment. To this end, the development is aimed at making the wallets as user-friendly as possible.
What makes Gulden unique:
- PoW2 - Proof of work + Witness/Staking - SegSig (Segregated Signature) - SIGMA (Semi Iterated Global Memory Argon) - Linking (Control your mobile wallet from your desktop wallet) - Wallet accounts - Unity (Unified codebase) - Delta (Difficulty Algorithm) - Sonic (Fast Sync)
Features of Gulden explained:
PoW2: Gulden does not use a standard PoW consensus model, but the in-house developed PoW2 model. This is a combination of PoW and Witness. Miners control the transactions and the Witness controls the miners. In order to get the same chance of success for a double spend as for the single transaction approval systems it is therefore necessary not to control >50% of the mining power or >50% of the number of coins in witness accounts but to own more than 71% of both systems. (0.71 * 0.71 = 0.5 so 50% chance).
Because many Gulden owners have their Gulden fixed in witness, it is difficult to get a 71% majority in witness. There are now more than 100 million Gulden in witness. In order to get a 71% majority, an attacker has to secure an additional 220 million Gulden in witness. Apart from the fact that this is almost impossible, the price of the Gulden would go up sky high if so much Gulden had to be bought by the attacker. And because the attacker has to lock the Gulden, it looks like a bank robber who is going to rob his own bank. So such an attack is theoretically possible, but not possible in reality.
Anyone can become a witness: by locking an amount of Gulden in a Witness account in the desktop wallet for a certain amount of time. Depending on the weighting of the witness account (chosen duration and amount in the account) the witness earns rewards. The advantage of this system is that the Gulden blockchain can withstand 51% attacks without relying heavily on energy-guzzling PoW miners or vulnerable standard PoS systems. Transactions can be safely accepted after one confirmation instead of the standard 3-6 confirmations.

  1. PoW2 Whitepaper simply explained PoW² explored — A post-launch look at some of the security implications How to setup a Witness
SIGMA: Since October 17, 2019, the Gulden team has implemented the Sigma algorithm and since then it is possible to mine Gulden solo without additional equipment. The algorithm is asic resistant and can be done on a normal desktop computer using it’s CPU. One can simply use this CPU mining algorithm by creating a mining account in the desktop wallet and start mining Gulden.
SegSig - Segregated Signature - Detailed article still to be published but was implemented with PoW2. Advantages of Segregated Signature: 1. 58% space saving on all transactions. More then twice the bitcoin SegWit implementation. 2. 58% increased transaction throughput. No block size or frequency changes needed. 3. Overhaul to the transaction script system which allowed us to implement PoW² and SegSig as clean as possible along with other benefits.

Please take your time and read the technicals on this coin as its truly phenomenal and seriously under valorised and recognised. Barely any effort has been made to market its potential but you can judge yourself. Read the PoW2 Whitepaper or the short version PoW2 simply explained

Filecoin | Development Status and Mining Progress

Author: Gamals Ahmed, CoinEx Business Ambassador
https://preview.redd.it/5bqakdqgl3g51.jpg?width=865&format=pjpg&auto=webp&s=b709794863977eb6554e3919b9e00ca750e3e704
A decentralized storage network that transforms cloud storage into an account market. Miners obtain the integrity of the original protocol by providing data storage and / or retrieval. On the contrary, customers pay miners to store or distribute data and retrieve it.
Filecoin announced, that there will be more delays before its main network is officially launched.
Filecoin developers postponed the release date of their main network to late July to late August 2020.
As mentioned in a recent announcement, the Filecoin team said that the initiative completed the first round of the internal protocol security audit. Platform developers claim that the results of the review showed that they need to make several changes to the protocol’s code base before performing the second stage of the software testing process.
Created by Protocol Labs, Filecoin was developed using File System (IPFS), which is a peer-to-peer data storage network. Filecoin will allow users to trade storage space in an open and decentralized market.
Filecoin developers implemented one of the largest cryptocurrency sales in 2017. They have privately obtained over $ 200 million from professional or accredited investors, including many institutional investors.
The main network was slated to launch last month, but in February 2020, the Philly Queen development team delayed the release of the main network between July 15 and July 17, 2020.
They claimed that the outbreak of the Coronavirus (COVID-19) in China was the main cause of the delay. The developers now say that they need more time to solve the problems found during a recent codecase audit.
The Filecoin team noted the following:
“We have drafted a number of protocol changes to ensure that building our major network launch is safe and economically sound.” The project developers will add them to two different implementations of Filecoin (Lotus and go-filecoin) in the coming weeks.
Filecoin developers conducted a survey to allow platform community members to cast their votes on three different launch dates for Testnet Phase 2 and mainnet.
The team reported that the community gave their votes. Based on the vote results, the Filecoin team announced a “conservative” estimate that the second phase of the network test should begin by May 11, 2020. The main Filecoin network may be launched sometime between July 20 and August 21, 2020.
The updates to the project can be found on the Filecoin Road Map.
Filecoin developers stated:
“This option will make us get the most important protocol changes first, and then implement the rest as protocol updates during testnet.” Filecoin is back down from the final test stage.
Another filecoin decentralized storage network provider launched its catalytic test network, the final stage of the storage network test that supports the blockchain.
In a blog post on her website, Filecoin said she will postpone the last test round until August. The company also announced a calibration period from July 20 to August 3 to allow miners to test their mining settings and get an idea of how competition conditions affected their rewards.
Filecoin had announced earlier last month that the catalytic testnet test would precede its flagship launch. The delay in the final test also means that the company has returned the main launch window between August 31 and September 21.
Despite the lack of clear incentives for miners and multiple delays, Filecoin has succeeded in attracting huge interest, especially in China. Investors remained highly speculating on the network’s mining hardware and its premium price.
Mining in Filecoin
In most blockchain protocols, “miners” are network participants who do the work necessary to promote and maintain the blockchain. To provide these services, miners are compensated in the original cryptocurrency.
Mining in Filecoin works completely differently — instead of contributing to computational power, miners contribute storage capacity to use for dealing with customers looking to store data.
Filecoin will contain several types of miners:
Storage miners responsible for storing files and data on the network. Miners retrieval, responsible for providing quick tubes for file recovery. Miners repair to be carried out.
Storage miners are the heart of the network. They earn Filecoin by storing data for clients, and computerizing cipher directories to check storage over time. The probability of earning the reward reward and transaction fees is proportional to the amount of storage that the Miner contributes to the Filecoin network, not the hash power.
Retriever miners are the veins of the network. They earn Filecoin by winning bids and mining fees for a specific file, which is determined by the market value of the said file size. Miners bandwidth and recovery / initial transaction response time will determine its ability to close recovery deals on the network.
The maximum bandwidth of the recovery miners will determine the total amount of deals that it can enter into.
In the current implementation, the focus is mostly on storage miners, who sell storage capacity for FIL.

Hardware recommendations

The current system specifications recommended for running the miner are:
Compared to the hardware requirements for running a validity checker, these standards are much higher — although they definitely deserve it. Since these will not increase in the presumed future, the money spent on Filecoin mining hardware will provide users with many years of reliable service, and they pay themselves many times. Think of investing as a small business for cloud storage. To launch a model on the current data hosting model, it will cost millions of dollars in infrastructure and logistics to get started. With Filecoin, you can do the same for a few thousand dollars.
Proceed to mining
Deals are the primary function of the Filecoin network, and it represents an agreement between a client and miners for a “storage” contract.
Once the customer decides to have a miner to store based on the available capacity, duration and price required, he secures sufficient funds in a linked portfolio to cover the total cost of the deal. The deal is then published once the mine accepts the storage agreement. By default, all Filecoin miners are set to automatically accept any deal that meets their criteria, although this can be disabled for miners who prefer to organize their deals manually.
After the deal is published, the customer prepares the data for storage and then transfers it to the miner. Upon receiving all the data, the miner fills in the data in a sector, closes it, and begins to provide proofs to the chain. Once the first confirmation is obtained, the customer can make sure the data is stored correctly, and the deal has officially started.
Throughout the deal, the miner provides continuous proofs to the chain. Clients gradually pay with money they previously closed. If there is missing or late evidence, the miner is punished. More information about this can be found in the Runtime, Cut and Penalties section of this page.
At Filecoin, miners earn two different types of rewards for their efforts: storage fees and reward prevention.
Storage fees are the fees that customers pay regularly after reaching a deal, in exchange for storing data. This fee is automatically deposited into the withdrawal portfolio associated with miners while they continue to perform their duties over time, and is locked for a short period upon receipt.
Block rewards are large sums given to miners calculated on a new block. Unlike storage fees, these rewards do not come from a linked customer; Instead, the new FIL “prints” the network as an inflationary and incentive measure for miners to develop the chain. All active miners on the network have a chance to get a block bonus, their chance to be directly proportional to the amount of storage space that is currently being contributed to the network.
Duration of operation, cutting and penalties
“Slashing” is a feature found in most blockchain protocols, and is used to punish miners who fail to provide reliable uptime or act maliciously against the network.
In Filecoin, miners are susceptible to two different types of cut: storage error cut, unanimously reduce error.
Storage Error Reduction is a term used to include a wider range of penalties, including error fees, sector penalties, and termination fees. Miners must pay these penalties if they fail to provide reliability of the sector or decide to leave the network voluntarily.
An error fee is a penalty that a miner incurs for each non-working day. Sector punishment: A penalty incurred by a miner of a disrupted sector for which no error was reported before the WindowPoSt inspection.
The sector will pay an error fee after the penalty of the sector once the error is discovered.
Termination Fee: A penalty that a miner incurs when a sector is voluntary or involuntarily terminated and removed from the network.
Cutting consensus error is the penalty that a miner incurs for committing consensus errors. This punishment applies to miners who have acted maliciously against the network consensus function.
Filecoin miners
Eight of the top 10 Felticoin miners are Chinese investors or companies, according to the blockchain explorer, while more companies are selling cloud mining contracts and distributed file sharing system hardware. CoinDesk’s Wolfe Chao wrote: “China’s craze for Filecoin may have been largely related to the long-standing popularity of crypto mining in the country overall, which is home to about 65% of the computing power on Bitcoin at discretion.”
With Filecoin approaching the launch of the mainnet blocknet — after several delays since the $ 200 million increase in 2017 — Chinese investors are once again speculating strongly about network mining devices and their premium prices.
Since Protocol Labs, the company behind Filecoin, released its “Test Incentives” program on June 9 that was scheduled to start in a week’s time, more than a dozen Chinese companies have started selling cloud mining contracts and hardware — despite important details such as economics Mining incentives on the main network are still endless.
Sales volumes to date for each of these companies can range from half a million to tens of millions of dollars, according to self-reported data on these platforms that CoinDesk has watched and interviews with several mining hardware manufacturers.
Filecoin’s goal is to build a distributed storage network with token rewards to spur storage hosting as a way to drive wider adoption. Protocol Labs launched a test network in December 2019. But the tokens mined in the testing environment so far are not representative of the true silicon coin that can be traded when the main network is turned on. Moreover, the mining incentive economics on testnet do not represent how final block rewards will be available on the main network.
However, data from Blockecoin’s blocknetin testnet explorers show that eight out of 10 miners with the most effective mining force on testnet are currently Chinese miners.
These eight miners have about 15 petabytes (PB) of effective storage mining power, accounting for more than 85% of the total test of 17.9 petable. For the context, 1 petabyte of hard disk storage = 1000 terabytes (terabytes) = 1 million gigabytes (GB).
Filecoin craze in China may be closely related to the long-standing popularity of crypt mining in the country overall, which is home to about 65% of the computing power on Bitcoin by estimation. In addition, there has been a lot of hype in China about foreign exchange mining since 2018, as companies promote all types of devices when the network is still in development.
“Encryption mining has always been popular in China,” said Andy Tien, co-founder of 1475, one of several mining hardware manufacturers in Philquin supported by prominent Chinese video indicators such as Fenbushi and Hashkey Capital.
“Even though the Velikoyen mining process is more technologically sophisticated, the idea of mining using hard drives instead of specialized machines like Bitcoin ASIC may be a lot easier for retailers to understand,” he said.
Meanwhile, according to Feixiaohao, a Chinese service comparable to CoinMarketCap, nearly 50 Chinese crypto exchanges are often somewhat unknown with some of the more well-known exchanges including Gate.io and Biki — have listed trading pairs for Filecoin currency contracts for USDT.
In bitcoin mining, at the current difficulty level, one segment per second (TH / s) fragmentation rate is expected to generate around 0.000008 BTC within 24 hours. The higher the number of TH / s, the greater the number of bitcoins it should be able to produce proportionately. But in Filecoin, the efficient mining force of miners depends on the amount of data stamped on the hard drive, not the total size of the hard drive.
To close data in the hard drive, the Filecoin miner still needs processing power, i.e. CPU or GPU as well as RAM. More powerful processors with improved software can confine data to the hard drive more quickly, so miners can combine more efficient mining energy faster on a given day.
As of this stage, there appears to be no transparent way at the network level for retail investors to see how much of the purchased hard disk drive was purchased which actually represents an effective mining force.
The U.S.-based Labs Protocol was behind Filecoin’s initial coin offer for 2017, which raised an astonishing $ 200 million.
This was in addition to a $ 50 million increase in private investment supported by notable venture capital projects including Sequoia, Anderson Horowitz and Union Square Ventures. CoinDk’s parent company, CoinDk, has also invested in Protocol Labs.
After rounds of delay, Protocol Protocols said in September 2019 that a testnet launch would be available around December 2019 and the main network would be rolled out in the first quarter of 2020.
The test started as promised, but the main network has been delayed again and is now expected to launch in August 2020. What is Filecoin mining process?
Filecoin mainly consists of three parts: the storage market (the chain), the blockecin Filecoin, and the search market (under the chain). Storage and research market in series and series respectively for security and efficiency. For users, the storage frequency is relatively low, and the security requirements are relatively high, so the storage process is placed on the chain. The retrieval frequency is much higher than the storage frequency when there is a certain amount of data. Given the performance problem in processing data on the chain, the retrieval process under the chain is performed. In order to solve the security issue of payment in the retrieval process, Filecoin adopts the micro-payment strategy. In simple terms, the process is to split the document into several copies, and every time the user gets a portion of the data, the corresponding fee is paid. Types of mines corresponding to Filecoin’s two major markets are miners and warehousers, among whom miners are primarily responsible for storing data and block packages, while miners are primarily responsible for data query. After the stable operation of the major Filecoin network in the future, the mining operator will be introduced, who is the main responsible for data maintenance.
In the initial release of Filecoin, the request matching mechanism was not implemented in the storage market and retrieval market, but the takeover mechanism was adopted. The three main parts of Filecoin correspond to three processes, namely the stored procedure, retrieval process, packaging and reward process. The following figure shows the simplified process and the income of the miners:
The Filecoin mining process is much more complicated, and the important factor in determining the previous mining profit is efficient storage. Effective storage is a key feature that distinguishes Filecoin from other decentralized storage projects. In Filecoin’s EC consensus, effective storage is similar to interest in PoS, which determines the likelihood that a miner will get the right to fill, that is, the proportion of miners effectively stored in the entire network is proportional to final mining revenue.
It is also possible to obtain higher effective storage under the same hardware conditions by improving the mining algorithm. However, the current increase in the number of benefits that can be achieved by improving the algorithm is still unknown.
It seeks to promote mining using Filecoin Discover
Filecoin announced Filecoin Discover — a step to encourage miners to join the Filecoin network. According to the company, Filecoin Discover is “an ever-growing catalog of numerous petabytes of public data covering literature, science, art, and history.” Miners interested in sharing can choose which data sets they want to store, and receive that data on a drive at a cost. In exchange for storing this verified data, miners will earn additional Filecoin above the regular block rewards for storing data. Includes the current catalog of open source data sets; ENCODE, 1000 Genomes, Project Gutenberg, Berkley Self-driving data, more projects, and datasets are added every day.
Ian Darrow, Head of Operations at Filecoin, commented on the announcement:
“Over 2.5 quintillion bytes of data are created every day. This data includes 294 billion emails, 500 million tweets and 64 billion messages on social media. But it is also climatology reports, disease tracking maps, connected vehicle coordinates and much more. It is extremely important that we maintain data that will serve as the backbone for future research and discovery”.
Miners who choose to participate in Filecoin Discover may receive hard drives pre-loaded with verified data, as well as setup and maintenance instructions, depending on the company. The Filecoin team will also host the Slack (fil-Discover-support) channel where miners can learn more.
Filecoin got its fair share of obstacles along the way. Last month Filecoin announced a further delay before its main network was officially launched — after years of raising funds.
In late July QEBR (OTC: QEBR) announced that it had ceded ownership of two subsidiaries in order to focus all of the company’s resources on building blockchain-based mining operations.
The QEBR technology team previously announced that it has proven its system as a Filecoin node valid with CPU, GPU, bandwidth and storage compatibility that meets all IPFS guidelines. The QEBR test system is connected to the main Filecoin blockchain and the already mined filecoin coin has already been tested.
“The disclosure of Sheen Boom and Jihye will allow our team to focus only on the upcoming global launch of Filecoin. QEBR branch, Shenzhen DZD Digital Technology Ltd. (“ DZD “), has a strong background in blockchain development, extraction Data, data acquisition, data processing, data technology research. We strongly believe Filecoin has the potential to be a leading blockchain-based cryptocurrency and will make every effort to make QEBR an important player when Mainecoin mainnet will be launched soon”.
IPFS and Filecoin
Filecoin and IPFS are complementary protocols for storing and sharing data in a decentralized network. While users are not required to use Filecoin and IPFS together, the two combined are working to resolve major failures in the current web infrastructure.
IPFS
It is an open source protocol that allows users to store and transmit verifiable data with each other. IPFS users insist on data on the network by installing it on their own device, to a third-party cloud service (known as Pinning Services), or through community-oriented systems where a group of individual IPFS users share resources to ensure the content stays live.
The lack of an integrated catalytic mechanism is the challenge Filecoin hopes to solve by allowing users to catalyze long-term distributed storage at competitive prices through the storage contract market, while maintaining the efficiency and flexibility that the IPFS network provides.
Using IPFS
In IPFS, the data is hosted by the required data installation nodes. For data to persist while the user node is offline, users must either rely on their other peers to install their data voluntarily or use a central install service to store data.
Peer-to-peer reliance caching data may be a good thing as one or multiple organizations share common files on an internal network, or where strong social contracts can be used to ensure continued hosting and preservation of content in the long run. Most users in an IPFS network use an installation service.
Using Filecoin
The last option is to install your data in a decentralized storage market, such as Filecoin. In Filecoin’s structure, customers make regular small payments to store data when a certain availability, while miners earn those payments by constantly checking the integrity of this data, storing it, and ensuring its quick recovery. This allows users to motivate Filecoin miners to ensure that their content will be live when it is needed, a distinct advantage of relying only on other network users as required using IPFS alone.
Filecoin, powered by IPFS
It is important to know that Filecoin is built on top of IPFS. Filecoin aims to be a very integrated and seamless storage market that takes advantage of the basic functions provided by IPFS, they are connected to each other, but can be implemented completely independently of each other. Users do not need to interact with Filecoin in order to use IPFS.
Some advantages of sharing Filecoin with IPFS:
Of all the decentralized storage projects, Filecoin is undoubtedly the most interested, and IPFS has been running stably for two years, fully demonstrating the strength of its core protocol.
Filecoin’s ability to obtain market share from traditional central storage depends on end-user experience and storage price. Currently, most Filecoin nodes are posted in the IDC room. Actual deployment and operation costs are not reduced compared to traditional central cloud storage, and the storage process is more complicated.
PoRep and PoSt, which has a large number of proofs of unknown operation, are required to cause the actual storage cost to be so, in the early days of the release of Filecoin. The actual cost of storing data may be higher than the cost of central cloud storage, but the initial storage node may reduce the storage price in order to obtain block rewards, which may result in the actual storage price lower than traditional central cloud storage.
In the long term, Filecoin still needs to take full advantage of its P2P storage, convert storage devices from specialization to civil use, and improve its algorithms to reduce storage costs without affecting user experience. The storage problem is an important problem to be solved in the blockchain field, so a large number of storage projects were presented at the 19th Web3 Summit. IPFS is an important part of Web3 visibility. Its development will affect the development of Web3 to some extent. Likewise, Web3 development somewhat determines the future of IPFS. Filecoin is an IPFS-based storage class project initiated by IPFS. There is no doubt that he is highly expected.

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.

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.

Methods of "difficulty retargeting" in the PYRK project

Methods of
Hello. 👋🏻 Today we will tell you about MultiShield and difficulty retargeting.
📌 In mining with the Proof-of-Work algorithm, the goal determines the complexity and, therefore, affects the time required to find a solution. As a result, logical questions arise, why is difficulty regulated, who corrects it, and how?
📌 Blocks in the blockchain are generated every n minutes. This determines the frequency of issuing the currency and the speed of settlement of transactions. It must remain constant not only for a short period, but also for many decades. The power of computers is growing rapidly and the number of mining participants is also constantly changing. Given these changes, the block generation time should remain unchanged. For this, the complexity of mining must be adjusted.
📌 For this, there is a retargeting of complexity, which occurs automatically and on each node independently. If the network finds blocks faster than every n minutes, the complexity increases (the goal decreases). If block detection is slower than expected, complexity decreases (target increases).
🛡 PYRK MultiShield solution
🔹 PYRK has a 90-second block timing target, meaning mathematically based on the previous blocks the "difficulty" in finding the cryptographic answer for each block will become harder or easier in order to maintain an approximate 90-second block timing. Miners sometimes change between the blockchains that they mine, especially on smaller chains, in order to maximize profits. For chains that have sporadic mining bursts this can cause long periods of extremely high difficulty, which results in exceedingly long block times.
🔹 MultiShield adjusts after each block, rather than once every 2016 blocks (like originally in Bitcoin). MultiShield is designed to let the difficulty "drop" very fast, in order that the chain doesn't freeze. MultiShield was originally created to account for such wild fluctuations, so that the blockchain doesn't "freeze" when a large exodus of hash power occurs. It also means miners cannot flood a few consecutive blocks with a high amount of hash power and benefit from low difficulty, giving blocks near instantly one after another before traditional difficulty retargeting occurs.

The soundness, the essential feature of the money that we want.

It is the cost of mining that adjusts to the coin price, not the other way round.
It is a common fallacy to believe that the price comes from the cost to produce something, it is called the labour theory of value, and it has been shown to be wrong. This is demonstrated clearly with bitcoin, which is a rather clean experiment, because it adjusts so quickly. The market finds the right price with someone offering to sell coins, other to buy coins, the hashing cost follows.
And also it is the cost of mining, not the hashrate, that is decided by the value of the coins.
With gold it is the same. Some people in the gold bug community understand this, and they can show that the production increases with the increasing market value of gold. It is not so clear, because the investment needed for gold production is so large, but if you compare price and production volume (in gold there is no difficulty adjustment, so produced volume will increase), you can see that there is a delay of about 10 years, understood to be 5 years to make the investment decision, then another 5 years to actually develop a new mine. The cost increases for the new mines because they use slightly less rich deposits, and the mines with better richness will increase their cost by more expensive land cost, more tax. higher labour prices and other cost driving factors. Likewise, the profit can change a lot but will slowly converge to the general profit level, which has its roots in the time preference. With this mechanism, nobody gets free gold, you have to buy it or mine it for approximately the same cost. As in bitcoin, anybody can mine, and gold is everywhere, it is in the ground you stand on right now, not rich enough currently to extract it, but it could be done. There is no need for a central bank for gold, and this lack of a need for an authority is what makes the gold sound.
The role of the difficulty adjustment is to decide a timeframe for the initial distribution of coins (with the halving plan), and to have a predetermined block time, which is needed for payments. It is not fundamental for the soundness. The soundness is that nobody gets coins for free, and the resulting lack of need of an authority. So what would happen if there was no difficulty adjustment? This is a thought experiment, but it can be useful for the understanding. With increased coin price, the miners would put more effort into mining, and the time between blocks would decrease (block rate increases). It would go down to one minute, a few seconds, and we would get lots of orphans and reorgs. We would end up with miners producing hundreds of blocks per second, and finding a block is for a miner just half the work, because most of the blocks he finds will be abandoned, the effort wasted, adding to his cost. But the coin would still be sound. The halvings would come weekly, and all coins will be mined in the short time, but the cost of newfound coins would be the same as now, approximately the market price. We need the difficulty for various reasons, to stretch out the coin creation, and give the market time to adapt, and to make sure we have a reasonable block frequency for the payment function. Summa summarum, the difficulty adjustment is needed, but it is not essential to the soundness.
I could construct examples from production of consumer goods that show the same, first value from consumer preferences, then the cost follows (and volume, if practical).

Proof of Drinks: An Open-Source Bitcoin Drinking Game

I’ve developed a new game that is played P2P…
Proof of Drinks: An Open-Source Bitcoin Drinking Game
GAME RULES
Player Types:
1. Includes Drinkers, Buyers, and Sellers 2. Anyone within The Market may play any of the aforementioned roles at any time. 3. Manages BITCOIN PROTOCOL - Block Reward (frequency, amount, halving) - Die Rolls - Drink Pour 
1. Acts autonomously; is not included within The Market. 2. Sells glasses and drinks to Drinkers. 3. Manages PRICE LIST OF GOODS - Glasses (fiat/glass) - Drinks (fiat/oz.) 
1. Acts autonomously; is not included within The Market. 2. Manages MONETARY POLICY - Inflation Rate - Circulating Supply of Fiat 
Items needed:
  1. Copies of GAME RULES, BITCOIN PROTOCOL, PRICE LIST OF GOODS, and MONETARY POLICY.
  2. One six-sided die.
  3. A number of six-ounce measuring glasses equal to the number of players within The Market.
  4. Drinks (alcoholic or otherwise).
  5. Fiat money (or Monopoly money).
  6. Minimum 6 players or so.
Object of the Game:
  1. To learn the mechanics of bitcoin and the economy through drinking and having fun.
  2. The game ends when one or more of the following conditions are met:
    • You run out of drinks.
    • Everyone is tired of drinking.
    • Everyone is tired of playing.
  3. At the end of the game, the person with the highest net worth (fiat + bitcoin) is deemed The Winner.
General Rules and Definitions:
  1. All die rolls are performed in front of all participants.
  2. Bathroom breaks are permitted, however gameplay continues. If a Drinker is in the bathroom during their round, their round is forfeited.
  3. Anyone within The Market may buy and sell anything at anytime.
  4. Round: The procedure for drinking; may or may not result in the production of bitcoin.
  5. Block: A round that results in the production of bitcoin.
  6. Anyone within The Market can propose a change to any rule at any time.
    • If everyone agrees, game play continues with the new rule.
    • If no one agrees, the person who proposed the change may continue playing or quit the game.
    • If some, but not all, agree, then the game may be forked into two separate games (Note: this may cause hurt feelings). The Government and The Bartender tend to both games.
  7. All values (bitcoin, block reward, fiat, etc) are to be rounded to the nearest whole number.
Analogies:
  1. Drinkers = Miners
  2. Glasses = Mining equipment
  3. Drinking = Proof of Work
  4. Die roll after drinking = Mining for the nonce
  5. Drink pour = Difficulty
  6. Bathroom break = Mining equipment maintenance
  7. All drinks and die rolls observed by everyone = Nodes validating
Game Setup:
  1. Designate a minimum of one player to be The Government.
  2. Designate a minimum of one player to be The Bartender.
  3. All other players (minimum 2? 3? 4?) are collectively The Market.
  4. The Government gives The Bartender and everyone within The Market ___ dollars each.
  5. For the first round, everyone within The Market is a Drinker (in subsequent rounds, anyone can step in our step out of the Drinker role).
  6. All Drinkers claim a chair around a table.
  7. All Drinkers purchase a glass from The Bartender at ___ dollars per glass. (Use a 6 oz. measuring glass for ease of pour.)
  8. All Drinkers roll a die; the Drinker with the highest number goes first. Subsequent rounds proceed clockwise.
  9. The Bartender determines the initial Cost of Drinking (fiat/drink).
  10. Determine the beginning Block Reward (50?).
Round Procedure:
  1. Determine the Nonce
    • Someone in The Market rolls a die. The number rolled is the Nonce for the Block.
  2. Determine the Pour
    • Someone, other than the Drinker for this round, rolls a die. The number rolled equals the amount of drink poured (e.g., a roll of “3” means 3 ounces is poured into the Drinker’s glass).
  3. The Drinker drinks the pour, then, once The Market has collectively determined the glass is free of liquid, the Drinker rolls a die. All participants in The Market verify the die roll.
    • If the die matches the Nonce, the Drinker receives the Block Reward! It is now the next Drinker’s turn, beginning again with Step 1 above.
    • If the die does not match the Nonce, no Block Reward is granted. It is now the next Drinker’s turn, beginning with Step 2 above.
  4. Every 10 Blocks, the Block Reward is cut in half.
  5. Once all Drinkers have completed a Round, The Government determines a new Inflation Rate and inflates the Circulating Supply of Fiat accordingly.
    • The Government rolls a die in another room then comes out and announces the result of the die roll. The number of the result is the inflation rate (e.g., if the roll is “3” the inflation rate is 3%).
    • The Government multiplies the Circulating Supply of Fiat by the Inflation Rate and adds this amount to the Circulating Supply of Fiat. The Government can do anything it wants with the fiat created.
  6. The value of each bitcoin (fiat/bitcoin) is determined by members of The Market.
    • For the determination of the Winner at the end of the game, the final value of bitcoin is the last value at which it traded.

Solve the "storage, mining pool and exchange centralization", and only generate 1G data every year(only pc-miner)

The blockheader has two segments with a total length of 64 bit0 (of which blocktime is 64 bits), which strongly prevents the collapse effect of the sha256 operation in the ASIC miner, so that the mining difficulty will not increase indefinitely. The centralization for the high hashrate of the mining pool is strongly restricted. Census and prune the transactions (at most 4 outputs per transaction) whose all outputs are spent,in the block below 1300 depth in batches(i.e. clear up the input and output at the same time, and only keep the version of all-outs-spent transaction on the disk,--not serialize vin and vout). 250 for each batch, 20 block files(one file per block) will be reconstructed for each block received from other nodes, that is to say, 5000 transactions will be pruned at a time. And special mechanism is used to make the synchronization of data from malicious nodes error free. Only 1G data is increased every year. The data it running for 1000 years will be no more than 1T. Block size is 2M, and only 1g data is increased every year without SPV, which strongly prevents the storage of a large number of block data reducing the number of nodes. At the same time, 'four outputs per tx' limit the settlement of the mining pool, and strongly prevent the centralization of the mining pool. For example, the settlement is sent to 4000 miners, which requires 1000 transactions. All currencies are locked in the maturity of 300 blocks (the input can only be used as prevout after 300 blocks), which strongly prevents the frequency of trading speculation, the crash from the online exchange, and prevent the centralization of the biggest online exchange in the world.
This has achieved "absolute decentralization".
At present, the tip height is only 600, and there is no pre-mined. The RPC is stable and reliable same as bitcoin 0.10.2. No segwit but P2SH, a little change based on 0.10.2. Usage: $ /download-directory/bitcoind -addnode =47.114.58.108 (same for Ubuntu) with bitcoin.conf configuration file

WaykiChain CSO, Wayki Sun: Vaulting Ambitions Carried Boundless Energy

“Here we must run as fast as we can just to stay in place.”.
— — — Alice in Wonderland
Once, this was just a fairy tale, but now, in the blockchain industry, it has become the reality. The fairy tale came true in the blockchain industry.
Looking back on 2019, the world’s various uncertainty still while blockchain takes the real lead Having the whole world in view, the stablecoin project Libra has become a subject of the U.S. Congress, starting off the tremendous craze in blockchain worldwide, by storm; while Chinese government introduces a new policy that lists blockchain as an important breakthrough for its innovation focus.
It is in this historical turning point that Waykichain has successfully completed its own transformation.
Coping with the times, the reflection of the trend
At WaykiChain’ inception, WaykiChain entered the industry via the most appropriate entry point prediction, which its full enthusiasm has been frustrated by the policy of cognitive. Since then, Waykichain has retreated to ecosystem co-building. By providing one-stop help for the outstanding developers from all over the world, Waykichain has launched dozens of DApps in order to build its own public chain ecosystem.
There are full of obstacles and difficulties. Waykichain team has paid great attention and affection to the whole process. From technology, operation, promotion to marketing, all of which have caught up to the front of the industry in such experience and exploration.
As Wayki Sun, the “godfather” said, said: “The old conscious classicalists are always afraid of the arrival of new things, however, the efficient and advanced new system is so unstoppable.”
The changes in the industry have made some people like falling into ice caves but crying without tears, while others have ushered in more possibilities.
The key lies in whether the pulse of the development of the industry has been observed and the opportunities given by the times have been seized. In this way, even the detours will eventually become a rainbow to success.
All previous attempts and explorations let us deeply understand that innovation is not to take shortcuts, but to take root in the deepest reality, solve the problems of specific business scenarios, and match the rigid demand that lies deep inside of our users.
Taking the ecosystem as a breakthrough, Waykichain finally set its target in the financial direction.
Huatong Securities is the first case of Waykichain successfully landing in a business application scenario. As a successful precedent for cryptocurrency cross-border finance,
Huatong Securities has brought significant returns to investors in a series of new digital currency businesses. Data shows that some investors who participated in the subscription of new shares through Huatong Securities have achieved a return of over 30% in recent months. Through WUSD as the access channel, investors who have not been able to get involved in this field can also participate in it without obstacles.
Waykichain’s long-term: based on core values
Facing the rapid changes in the market, WaykiChain innovated from time to time, constantly iterating new ways of business paths. In the face of the uncertainty of the world, Waykichain has always adhered to its long-term, and through its internal cultivation, it used its own certainty to deal with the uncertainty of the world.
Such long-term is exactly the core value of Waykichain:
Firstly, WaykiChain will continue to maintain as a global leader in public chain technology and mechanisms.
The four-letter codes “Long”, “Teng”, “Tiger”, and “Yue” signify the roadmap of the future evolution of the Waykichain public chain. In the current “Teng” stage of the public chain, Waykichain not only achieved a global leader in a number of hardcore technical indicators such as TPS (average stable at 3300, peak 7800), transfer speed but also reached the industry in terms of the underlying logic and technical architecture. Leading positions, such as the construction of stablecoin systems and DEX at the bottom of the public chain, have surpassed the general contract-based construction in terms of security, stability, scalability, the convenience of paying fees, etc. The decentralized cross-chain technology completed at the end of the quarter will bring cross-chain assets such as Bitcoin and Ethereum to Waykichain, which will stimulate tens of billions of value liquidity; and the upcoming integration of the WASM virtual machine will also allow Waykichain acquires dual virtual machine engines for higher compatibility and performance.
“Publicchain is still in the era of clash of Titans. When all goes to all, technology will win out.” As Wayki's assertion of the public chain’s technical status, these explorations of public chain technology and mechanism have not only given WaykiChain the greater commercial application potential of public chain, also allows the public chain facilities built on it to have a stronger industry competitive advantage.
Secondly, vigorously expand the supporting construction of the commercial scene around Waykichain.
Regardless of whether it was cut through my prediction at the beginning, or then focused on the application ecosystem, or currently grasping the financial direction, although the rudder is constantly adjusting, the voyage of exploring the business model has never stopped.
At present, a complete set of decentralized financial system surrounding the stable coin WUSD of Waykichain has taken shape, and the profit model and commercial development path built on this financial system have become increasingly clear, including cross-border finance, cross-border payment, decentralization currency, denominated currencies, financial derivative transactions, etc. will all be important business application scenarios for Waykichain. On the last day of 2019, the WICC’s total network mortgage volume has exceeded 16 million, and the main destination of the WUSD loan is Huatong Securities’ cross-border financial investment.
Breaking Technology Silos: High Global Consensus
Owning, without connecting, will eventually become a technology island. What Waykichain does is to link realistic business scenarios and huge users outside the circle, and finally form a high degree of global consensus.
The so-called consensus is people’s identification of the same thing and a community of unanimous beliefs. The extent to which this matter can reach consensus also determines its commercial value. It can be said that consensus is the root of the development of public chain and the entire commercial building. The global high consensus is the development direction of all blockchain projects.
And such a high degree of consensus involves many aspects, including not only the global leader in the technology and mechanism of Waykichain mentioned above, the supporting construction of business scenarios, etc., but also other important parts:
Internationalization of the Waykichain Team. At present, Waykichain has gathered a group of elite troops with great dedication, a sense of mission and a sense of belonging. This is the result of Waykichain’s long-term implementation of the introduction, cultivation and elite precipitation of outstanding personnel. In the future, the Waykichain team will be further internationalized. Through the international team, a global communication circle will be built to help the global strategic layout;
Introducing strategic investments such as top global venture capital. No matter whether the previous contact with Softbank or being invited to attend the Global Blockchain High-end Private Conference in Dubai, we are preparing for the introduction of the world’s top venture capital and this will strengthen the brand endorsement and help Waykichain’s extension Breakthrough development.
Strengthen technical cooperation with governments and large institutions. Earlier, WaykiChain had conducted returning visits with the Montenegrin government and had an in-depth exchange of views on the blockchain technology reform in the field of Montenegro International Trade and Finance. Through such high-standard technical cooperation, it can not only improve the operating efficiency of related fields but also accumulate rich experience and capital market reference for more national-level cooperation of Waykichain;
Launch more world first- and second-tier exchanges. Last year, Waykichain successfully launched Gate.io and Bithumb and other international first-tier exchanges, and other first-tier and second-tier exchanges are also actively contacting.
Through the creation of a high degree of global consensus, Waykichain will ultimately be given more business value and promote the landing of a business application ecosystem.
The magic weapon to win the future: Massive community expansion
The magic weapon to win the future is not how much resources you have, but how many resources you can mobilize. For this reason, in addition to having a high degree of consensus on a global scale, we also need a huge community as a vehicle that can be scheduled.
At present, through the global partner and ambassador system of various countries, Waykichain has formed a number of international communities around the world with Waykichain ambassadors as its core. Among them, 41 community managers (including global ambassadors) from 15 countries including U.S, the United Kingdom, France, Germany, Japan, Indonesia, Brazil, Vietnam, South Korea, Turkey, the Philippines, Russia, Spain, Ukraine, Bangladesh and Nigeria, including Nearly 30 international communities; and has held several offline events in Russia, Singapore, Turkey, Vietnam and South Korea.
On the basis of the achievements of single-point breakthroughs in some key countries and regions, we will continue to penetrate overseas markets and increase the frequency of offline meet-ups and overseas marketing activities. In the coming year, we plan to hold another 30 overseas offline meet-ups through official channels, and encourage and assist global volunteers to organize about 60 offline meet-ups on their own initiative.
Through the implementation of point-to-surface breakthroughs, we will continue to attract incremental users, and continue to expand the number of users in overseas communities while maintaining the steady growth of domestic communities, and truly form a situation of massive community expansion and a global chess market.
2020: Writing our own heroism
“Having a dream that doesn’t make you exhausted in this life, I think, is the best gift that life gives you.”
At that time, when the godfather wrote this sentence in the circle of friends, Waykichain was not born yet. But what happened in the next two years, we all know: once the seeds of dreams land, under the watering of ambition, not only take root, they are already germinating, they will grow wildly.
“To set a big goal, you must focus crazily and continue to work towards it.” This is not only the creed of Wayki but also his exhortation to the team. From top to bottom, with this “crazy energy” that constantly surpasses itself and pursues excellence, Waykichain is able to open its doors and build bridges on the road of technological evolution and in the cold winter of the industry.
On the high-speed track of the global public chains, WaykiChain built around the three dimensions of “core value as the foundation”, “global high consensus” and “mass community expansion”, the next goal will be to strive for the top five and even the top 3 positions of the global public chain. Let’s wait and see how this heroic epic belongs to us.

"Publicchain is still in the era of clash of Titans. When all goes to all, technology will win out." As Waykis assertion of the public chain's technical status, these explorations of public chain technology and mechanism have not only given WaykiChain the greater commercial application potential of public chain,
also allows the public chain facilities built on it to have a stronger industry competitive
advantage.
Secondly, vigorously expand the supporting construction of the commercial scene around Waykichain.
Regardless of whether it was cut through my prediction at the beginning, or then focused on the
application ecosystem, or currently grasping the financial direction, although the rudder is
constantly adjusting, the voyage of exploring the business model has never stopped.
At present, a complete set of decentralized financial system surrounding the stable coin WUSD of Waykichain has taken shape, and the profit model and commercial development path built on this financial system have become increasingly clear, including cross-border finance, cross-border payment, decentralization currency, denominated currencies, financial derivative transactions, etc. will all be important business application scenarios for Waykichain. On the last day of 2019, the WICC's total network mortgage volume has exceeded 16 million, and the main destination of the WUSD loan is Huatong Securities' cross-border financial investment.
Breaking Technology Silos: High Global Consensus
Owning, without connecting, will eventually become a technology island. What Waykichain does is to link realistic business scenarios and huge users outside the circle, and finally form a high degree of global consensus.
The so-called consensus is people's identification of the same thing and a community of unanimous beliefs. The extent to which this matter can reach consensus also determines its commercial value. It can be said that consensus is the root of the development of public chain and the entire commercial building. The global high consensus is the development direction of all blockchain projects.
And such a high degree of consensus involves many aspects, including not only the global leader in the technology and mechanism of Waykichain mentioned above, the supporting construction of business scenarios, etc., but also other important parts:
Internationalization of the Waykichain Team. At present, Waykichain has gathered a group of elite troops with great dedication, a sense of mission and a sense of belonging. This is the result of Waykichain's long-term implementation of the introduction, cultivation and elite precipitation of outstanding personnel. In the future, the Waykichain team will be further internationalized. Through the international team, a global communication circle will be built to help the global strategic layout;
Introducing strategic investments such as top global venture capital. No matter whether the previous contact with Softbank or being invited to attend the Global Blockchain High-end Private Conference in Dubai, we are preparing for the introduction of the world's top venture capital and this will strengthen the brand endorsement and help Waykichain's extension Breakthrough development.
Strengthen technical cooperation with governments and large institutions. Earlier, WaykiChain had conducted returning visits with the Montenegrin government and had an in-depth exchange of views on the blockchain technology reform in the field of Montenegro International Trade and Finance. Through such high-standard technical cooperation, it can not only improve the operating efficiency of related fields but also accumulate rich experience and capital market reference for more national-level cooperation of Waykichain;
Launch more world first- and second-tier exchanges. Last year, Waykichain successfully launched Gate.io and Bithumb and other international first-tier exchanges, and other first-tier and second-tier exchanges are also actively contacting.
Through the creation of a high degree of global consensus, Waykichain will ultimately be given more business value and promote the landing of a business application ecosystem.
The magic weapon to win the future: Massive community expansion
The magic weapon to win the future is not how much resources you have, but how many resources you can mobilize. For this reason, in addition to having a high degree of consensus on a global scale, we also need a huge community as a vehicle that can be scheduled.
At present, through the global partner and ambassador system of various countries, Waykichain has formed a number of international communities around the world with Waykichain ambassadors as its core. Among them, 41 community managers (including global ambassadors) from 15 countries including U.S, the United Kingdom, France, Germany, Japan, Indonesia, Brazil, Vietnam, South Korea, Turkey, the Philippines, Russia, Spain, Ukraine, Bangladesh and Nigeria, including Nearly 30 international communities; and has held several offline events in Russia, Singapore, Turkey, Vietnam and South Korea.
On the basis of the achievements of single-point breakthroughs in some key countries and regions, we will continue to penetrate overseas markets and increase the frequency of offline meet-ups and overseas marketing activities. In the coming year, we plan to hold another 30 overseas offline meet-ups through official channels, and encourage and assist global volunteers to organize about 60 offline meet-ups on their own initiative.
Through the implementation of point-to-surface breakthroughs, we will continue to attract incremental users, and continue to expand the number of users in overseas communities while maintaining the steady growth of domestic communities, and truly form a situation of massive community expansion and a global chess market.
2020: Writing our own heroism
"Having a dream that doesn't make you exhausted in this life, I think, is the best gift that life gives you."
At that time, when the godfather wrote this sentence in the circle of friends, Waykichain was not born yet. But what happened in the next two years, we all know: once the seeds of dreams land, under the watering of ambition, not only take root, they are already germinating, they will grow wildly.
"To set a big goal, you must focus crazily and continue to work towards it." This is not only the creed of Wayki but also his exhortation to the team. From top to bottom, with this "crazy energy" that constantly surpasses itself and pursues excellence, Waykichain is able to open its doors and build bridges on the road of technological evolution and in the cold winter of the industry.
On the high-speed track of the global public chains, WaykiChain built around the three dimensions of "core value as the foundation", "global high consensus" and "mass community expansion", the next goal will be to strive for the top five and even the top 3 positions of the global public chain. Let's wait and see how this heroic epic belongs to us.

IoT Testing !!!

IoT is a whole ecosystem that contains intelligent devices equipped with sensors (sensors) that provide remote control, storage, transmission and security of data. The Internet of Things (IoT) is an innovative solution in various areas such as healthcare, insurance, labor protection, logistics, ecology, etc. To unleash the full potential of using IoT devices, it is necessary to solve many problems related to standards, security, architecture, ecosystem construction, channels and device connection protocols. Today in the world, large organizations such as NIST, IEEE, ISO / IEC, and others make enormous efforts in addressing the issues of standardization, security, and the architecture of developed devices. Analysis of recent scientific research in the field of solving information security issues and data privacy of IoT devices showed positive results, but these methods and approaches are based on traditional methods of network security. The development and application of security mechanisms for IoT devices is a complex and heterogeneous task. In this regard, ensuring information security and the protection of sensitive data, as well as the availability of IoT devices, is the main purpose of writing this article. Given the above, many questions arise related to the security status of IoT devices, namely: What are the current standards and protocols for IoT? What are the requirements for ensuring information security of IoT devices? What security mechanisms do IoT devices have? What methods of testing IoT devices exist? Manufacturers and developers of IoT devices do not pay enough attention to security issues. With the development of cyber-attacks, attack vectors are becoming more sophisticated and aimed at several infrastructure elements at the same time. IoT infrastructure typically includes millions of connected objects and devices that store and share confidential information. Scenarios of theft and fraud, such as hacking and falsifying personal data, pose a serious threat to such IoT devices. Most IoT devices use the public Internet to exchange data, which makes them vulnerable to cyber-attacks. Modern approaches to information security often offer solutions to individual problems, when multi-level approaches offer increased resistance to cyber-attacks.
Challenges of testing IoT devices
To a request to name essential items, many would answer: food, a roof over your head, clothes … With one caveat: this was the case in the last century.
Since then, the species Homo Sapiens has accumulated needs. We need automatic sensors to control the lighting, not just switches, for smart systems to monitor health and car traffic. The list goes on … In general, we can make life easier and better.
Let’s try to figure out how all this Internet of things works before moving on to testing.

The Internet of things (or IoT) is a network that combines many objects: vehicles, home automation, medical equipment, microchips, etc. All these constituent elements accumulate and transmit data. Through this technology, the user controls the devices remotely.

Examples of IoT devices

# 1) Wearable technology: Fitbit Fitness Bracelets and Apple Watch smart watches sync seamlessly with other mobile devices.

IoT – watches and bracelets

Itís easier to collect health information: heart rate, body activity during sleep, etc.
# 2) Infrastructure and development The CitySense app analyzes lighting data online and turns lights on and off automatically. There are applications that control traffic lights or report on the availability of parking lots.
# 3) Health Some health monitoring systems are used in hospitals. The basis of their work is indicative data. These services control the dosage of drugs at different times of the day. For example, the UroSense application monitors the level of fluid in the body and, if necessary, increases this level. And doctors will learn about patient information wirelessly.
Technologies that are present in IoT RFID (Radio Frequency Identification), EPC (Electronic Product Code) NFC (ìNear Field Communicationî) provides two-way communication between devices. This technology is present in smartphones and is used for contactless transactions.
Bluetooth It is widely used in situations where near-field communication is sufficient. Most often present in wearable devices. Z-Wave. Low frequency RF technology. Most often used for home automation, lighting control, etc. WiFi. The most popular network for IoT (file, data and message transfer). IoT Testing Consider an example : a medical system that monitors health status, heart rate, fluid content, and sends reports to healthcare providers. Data is displayed in the system; archives available. And doctors are already deciding whether to take medication for the patient remotely.
IoT architecture
There are several approaches for testing the IoT architecture.
# 1) Usability: It is necessary to provide usability testing of each device. A medical device that monitors your health should be portable.
Sufficiently thought out equipment is needed that would send not only notifications, but also error messages, warnings, etc. The system must have an option that captures events, so that the end user understands. If this is not possible, event information is stored in the database. The ability to process data and exchange tasks between devices is carefully checked. # 2) IoT Security: Data is at the heart of all connected devices. Therefore, unauthorized access during data transfer is not ruled out. From the point of view of software testing, it is necessary to check how secure / encrypted the data is. If there is a UI, you need to check if it is password protected. # 3) Network features: Network connectivity and IoT functionality are critical. After all, we are talking about a system that is used for health purposes. Two main aspects are tested: The presence of a network , the possibility of data transfer (whether jobs are transferred from one device to another without any hitch). The scenario when there is no connection . Regardless of the level of reliability of the system, it is likely that the status of the system will be ìofflineî. If the network is unavailable, employees of the hospital or other organization need to know about it (notifications). Thus, they will be able to monitor the condition of the patient themselves, and not wait for the system to work. On the other hand, in such systems there is usually a mechanism that saves data if the system is offline. That is, data loss is eliminated. # 4) Efficiency: It is necessary to take into account the extent to which the healthcare solution is applicable in specific conditions. In testing, from 2 to 10 patients participate, data is transmitted to 10-20 devices. If the entire hospital is connected to the network, this is already 180-200 patients. That is, there will be more actual data than test data. In addition, it is necessary to test the utility for monitoring the system: current load, power consumption, temperature, etc. # 5) Compatibility testing: This item is always present in the plan for testing the IoT system. The compatibility of different versions of operating systems, browser types and their respective versions, devices of different generations, communication modes [for example, Bluetooth 2.0, 3.0] is extremely important for IoT. # 6) Pilot testing: Pilot testing is a mandatory point of the test plan. Only tests in the laboratory will allow us to conclude that the system is functional. In pilot testing, the number of users is limited. They make manipulations with the application and express their opinion. These comments turn out to be very helpful, they make a reliable application. # 7) Check for compliance: The system, which monitors the state of health, undergoes many compliance checks. It also happens that a software product passes all stages of testing, but fails the final test for compliance [testing is carried out by the regulatory body]. It is more advisable to check for compliance with norms and standards before starting the development cycle. # 8) Testing updates: IoT is a combination of many protocols, devices, operating systems, firmware, hardware, network layers, etc. When an update occurs – be it a system or something else of the above – rigorous regression testing is required. The overall strategy is being amended to avoid the difficulties associated with the upgrade.

IoT testing challengesIoT testing

# 1) Hard / soft IoT is an architecture in which software and hardware components are closely intertwined. Not only software is important, but also hard: sensors, gateways, etc.
Functional testing alone will not be enough to certify the system. All components are interdependent. IoT is much more complicated than simpler systems [only software or only hard].
# 2) Device Interaction Model Components of the network must interact in real time or close to real. All this becomes a single whole – hence the additional difficulties associated with IoT (security, backward compatibility and updates).
# 3) Testing data coming in real time Obtaining this data is extremely difficult. The matter is complicated by the fact that the system, as in the described case, may relate to the health sector.
# 4) UI An IoT network usually consists of different devices that are controlled by different platforms [iOS, Android, Windows, linux]. Testing is possible only on some devices, since testing on all possible devices is almost impossible.
# 5) Network Availability Network connectivity plays an important role in IoT. The data rate is increasing. IoT architecture should be tested under various connection conditions, at different speeds. Virtual network emulators in most cases are used to diversify network load, connectivity, stability, and other elements of load testing . But the evidence is always new scenarios, and the testing team does not know where the difficulties will arise in the future.

IoT Testing ToolsIoT and software

There are many tools that are used in testing IoT systems.
They are classified depending on the purpose:
# 1) Software: Wireshark : An open source tool. Used to monitor traffic in the interface, source / given host address, etc. Tcpdump : This tool does a similar job. The utility does not have a GUI, its interface is the command line. It enables the user to flash TCP / IP and other packets that are transmitted over the network. # 2) Hard: JTAG Dongle: A tool similar to debuggers in PC applications. Allows you to find defects in the code of the target platform and shows the changes step by step. Digital Storage Oscilloscope : checks various events using time stamps, power outages, signal integrity. Software Defined Radio : emulates a transmitter and receiver for various wireless gateways. IoT is an emerging market and many opportunities. In the foreseeable future, the Internet of things will become one of the main areas of work for tester teams. Network devices, smart gadget applications, communication modules – all this plays an important role in the study and evaluation of various services.
Total The approach to testing IoT may vary depending on the specific system / architecture.
Itís difficult to test IoT, but at the same time itís an interesting job, since testers have a good place to swing – there are many devices, protocols and operating systems.
PS You should try out the TAAS format (“tests from the user’s point of view”), and not just fulfill the formal requirements.
—————
Smart watches, baby-sitters, wireless gadgets and devices such as, for example, a portable radio station have long been part of everyday life.
Hackers have already proven that many of these attacks on IoT are possible.
Many people in general first learned about IoT security threats when they heard about the Mirai botnet in September 2016.
According to some estimates, Mirai infected about 2.5 million IoT devices, including printers, routers and cameras connected to the Internet.
The botnetís creators used it to launch distributed denial of service (DDoS) attacks, including an attack on the KrebsonSecurity cybersecurity blog.
In fact, the attackers used all devices infected with Mirai to try to connect to the target site at the same time, in the hope of suppressing the servers and preventing access to the site.
Since Mirai was first published on the news, attackers launched other botnet attacks on IoT, including Reaper and Hajime.
Experts say that such attacks are most likely in the future.
The Internet of Things (IoT) can bring many advantages to modern life, but it also has one huge drawback: security threats.
In its 2018 IOT forecasts, Forroter Research notes: ìSecurity threats are a major concern for companies deploying IoT solutions – in fact, this is the main task of organizations looking to deploy IoT solutions.
However, most firms do not regularly prevent IoT-specific security threats, and business pressure suppresses technical security issues. î
IoT security risks can be even more significant on the consumer side, where people are often unaware of potential threats and what they should do to avoid threats.
A 2017 IoT security survey sponsored by Gemalto Security Provider found that only 14 percent of consumers surveyed consider themselves IoT-aware.
This number is particularly noteworthy because 54 percent of the respondents owned an average of four IoT devices.
And these IoT security threats are not just theoretical.
Hackers and cybercriminals have already found ways to compromise many IoT devices and networks, and experts say that successful attacks are likely to increase.
Forrester predicted: “In 2018, we will see more attacks related to IoT … except that they will increase in scale and loss.”
What types of IoT security threats will enterprises and consumers face in 2018?
Based on historical precedent, here are ten of the most likely types of attacks.
  1. Botnets and DDoS attacks
  2. Remote recording The possibility that attackers can hack IoT devices and record owners without their knowledge is not revealed as a result of the work of hackers, but as a result of the work of the Central Intelligence Agency (CIA).
Documents released by WikiLeaks implied that the spy agency knew about dozens of zero-day exploits for IoT devices, but did not disclose errors, because they hoped to use vulnerabilities to secretly record conversations that would reveal the actions of alleged opponents of America.
Documents pointed to vulnerabilities in smart TVs, as well as on Android and iOS smartphones.
The obvious consequence is that criminals can also exploit these vulnerabilities for their vile purposes.
  1. Spam In January 2014, one of the first known attacks using IoT devices used more than 100,000 Internet-connected devices, including televisions, routers, and at least one smart refrigerator to send 300,000 spam emails per day.
The attackers sent no more than 10 messages from each device, which makes it very difficult to block or determine the location of the incident.
This first attack was not far from the last.
IoT spam attacks continued in the fall with the Linux.ProxyM IoT botnet.
  1. APTs In recent years, advanced persistent threats (APTs) have become a serious concern for security professionals.
APTs are carried out by funded and widespread attackers such as nation states or corporations that launch complex cyberattacks that are difficult to prevent or mitigate.
For example, the Stuxnet worm, which destroyed Iranian nuclear centrifuges and hacking Sony Pictures 2014, was attributed to nation states.
Because the critical infrastructure is connected to the Internet, many experts warn that APTs may launch a power-oriented IoT attack, industrial control systems, or other systems connected to the Internet.
Some even warn that terrorists could launch an attack on iOT, which could harm the global economy.
  1. Ransomware Ransomware has become too common on home PCs and corporate networks. Now experts say that it is only a matter of time before the attackers begin to block smart devices. Security researchers have already demonstrated the ability to install ransomware on smart thermostats. For example, they can raise the temperature to 95 degrees and refuse to return it to its normal state until the owner agrees to pay a ransom in Bitcoins. They can also launch similar attacks on garage doors, vehicles, or even appliances. How much would you pay to unlock your smart coffee pot first thing in the morning?
  2. Data theft Obtaining important data, such as customer names, credit card numbers, social security numbers, and other personal information, is still one of the main goals of cyber attacks.
IoT devices represent a whole new vector of attack for criminals looking for ways to invade corporate or home networks.
For example, if an improperly configured device or IoT sensor is connected to corporate networks, this can give attackers a new way to enter the network and potentially find the valuable data that they need.
  1. Home theft As smart locks and smart garage doors become more commonplace, it is also more likely that cybercriminals can become real thieves.
Home systems that are not properly protected can be vulnerable to criminals with sophisticated tools and software.
Security researchers are unlikely to have shown that itís quite easy to break into a house through smart locks from several different manufacturers, and smart garage doors do not seem to be much safer.
  1. Communication with children One of the most disturbing IoT security stories came from children.
One couple discovered that the stranger not only used his monitor for children to spy on their three-year-old son, this stranger also spoke with his child through the device.
Mother heard an unknown voice: ìWake up, boy, dad is looking for you,î and the child said that he was scared because at night someone was talking to him on an electronic device.
As more and more children’s gadgets and toys connect to the Internet, it seems likely that these frightening scenarios may become more common.
  1. Remote control of a vehicle As vehicles become smarter and more accessible on the Internet, they also become vulnerable to attack.
Hackers have shown that they can take control of a jeep, maximize air conditioning, change the radio station, start the wipers, and ultimately slow down the car.
The news led to the recall of 1.4 million cars, but whitehat researchers, following the original exploit, said they discovered additional vulnerabilities that were not fixed by the Chrysler patch applied to the recalled cars.
Although experts say the automotive industry is doing a great job of ensuring vehicle safety, it is almost certain that attackers will find new vulnerabilities in such smart cars.
  1. Personal attacks Sometimes IoT covers more than just devices – it can also include people who have connected medical devices implanted in their bodies.
An episode of the television series Homeland attempted a murder aimed at an implanted medical device, and former vice president Dick Cheney was so worried about this scenario that he turned off the wireless capabilities on his implanted defibrillator.
This kind of attack has not yet happened in real life, but it remains possible, as many medical devices become part of the IoT.
