The blockchain - Bitcoin.com Developer Platform

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.

Blockchain in the Public Sector – Webcast Q&A

Blockchain in the Public Sector – Webcast Q&A
Link to our website: https://block.co/blockchain-in-the-public-sector-webcast-qa/
Block.co fourth webcast titled "Digital Transformation of the Public Sector & The Upcoming Legislation of Blockchain Technology in Cyprus” was an immense success. We gathered some of the best experts in the field, Deputy Minister Kyriacos Kokkinos, Jeff Bandman, Steve Tendon, and Christiana Aristidou to share their experience and discuss with us the latest updates regarding Blockchain in the Public Sector.
In its fourth series of webcasts, Block.co gathered 281 people watching the event from 41 different countries, for a two-hour webcast where guests answered participants’ questions. Following the impressive outcome and response we received from the audience, Block.co’s team has done its best to address all the questions for which public information is available.
Below is a list of the questions that were made and were not answered due to time constraints during the webcast. For the remaining questions from our audience, the team will reach out to our distinguished guests to receive their comments and feedback. Please note, that the below information is only for informational purposes!
Question 1:
How can asset tracing be accomplished with bitcoins and cryptocurrency? And how can this be regulated?
Block.co Team Answer:
Digital Asset tracing may be accomplished with cryptocurrency intelligence solutions such as Cipher Trace and the ICE cryptocurrency intelligence program. FATF (Financial Action Task Force) embarked on a program of work from summer 2018 to June 2019 to strengthen and update the provisions dealing with virtual assets and virtual asset service providers. FATF updated Recommendations in October 2018 and Guidance in June 2019 include several new obligations that apply to VASPs. The so-called “Travel Rule” FATF announced in October 2019 agreed on the assessment criteria for how it will assess countries’ compliance with the new global standards. Under the Travel Rule, the transmitter’s financial institutions must include and send information in the transmittal order such as Information about the identity, name, address, and account number of the sender and its financial institution Information about the identity, name, address and account number of the recipient. The ”Travel Rule” is effectively being applied to cryptoasset transfers when there is a virtual asset service provider (VASP) involved. The scope of focus has broadened from “convertible” virtual assets to any virtual asset. Countries should make sure businesses can freeze crypto wallet or exchange accounts for sanctioned individuals.
Question 2:
Which kind of software or technical knowledge is required to develop cryptocurrency?
Block.co Team Answer:
It depends on the type of cryptocurrency you wish to create, as well as the preferred functionality and features, and characteristics of the token or coin (i.e. will it be pre-mined, what type of hashing or cryptographic algorithm will be used (i.e. proof of work (POW) or proof of stake (POS) or a hybrid of both), etc. Likewise, it is useful to utilize a programming language that is broadly used and supported by a vast and active development community; more data could be found here: more information could be found here: top programming languages in 2015/2016, published by IEEE here, and TIOBE. Hypothetically, you can utilize any programming language to make cryptocurrency digital money, however, the most widely recognized are C, C++, Java, Python, Perl. The beauty of cryptocurrencies is that you can literally have access to the entire Bitcoin and Ethereum open-source programming scripts, and create your alternate coin (altcoin).
Question 3:
Hello all, I want to know about the current status of the European Union Blockchain initiative in currency or public identity.
Block.co Team Answer:
Please refer to the European Services Blockchain Infrastructure (EBSI) website.
Question 4:
Mining is also the process of confirmation of transactions in the Bitcoin Blockchain. What is the process of confirmation of transactions in the Blockchain of an Organization? How do we call it?
Block.co Team Answer:
That would depend on the specific consensus algorithm used for the confirmation of transactions. The consensus algorithm is part of the blockchain protocol that defines the rules on how consensus is reached on that blockchain. In order to participate, entities on the blockchain must obey and follow the same consensus algorithm. Make sure to check our glossary for more information.
Question 5:
How does a small business implement blockchain into its current non-blockchain software systems? Who do they hire to install it?
Block.co Team Answer:
It is easy when there are APIs to connect the various software. For more information, you can check Block.co API.
Question 6:
What is your opinion on digitizing developing economies like India by using AI and blockchain?
Block.co Team Answer:
Watch a very interesting webinar on the matter by Mr. Prasanna:
Question 7:
Blockchain technologies have been around since 2008. What would you say has been the biggest obstacle in widespread adoption?
Block.co Team Answer:
In our opinion, the biggest obstacles are volatile cryptoasset prices, complicated UIs, undefined blockchain technology standards. Moreover, the legislation around the technologies is still now being developed and does not offer legal certainty for broader adoption.
Question 8:
Limitations to Blockchain Usability in the Public Sector?
Block.co Team Answer:
Blockchain in the Public Sector, like any other innovative concept with big potential, cannot be a solution to every problem. Users and developers are still figuring out technological and managerial challenges. From a technological perspective, some aspects such as platform scalability, validation methods, data standardization, and systems integration must still be addressed. From a managerial point of view, the questions include business model transformation, incentive structure, and transaction scale, and maturity. Read more here.
Question 9:
How can these blockchain initiatives be practical for the African context
Block.co Team Answer:
As long as the internet infrastructure is in place, these blockchain initiatives may have the same benefits for the African region.
Question 10:
What are some compelling use cases you’ve seen lately, and how do they serve to further legitimize blockchain as a solution?
Block.co Team Answer:
You can see the global trends from all around the world when it comes to further legitimization as a solution, with China leading the way. Read more here.
Question 11:
How does digital currency manage the issue of money laundering?
Block.co Team Answer:
Depends under which context you are looking at the term digital currency. A digital currency usually refers to a balance or a record stored in a distributed database, in an electronic computer database, within digital files or a stored-value card. Some examples of digital currencies are cryptocurrencies, virtual currencies, central bank digital currencies (CBDCs), and e-Cash. The Financial Action Task Force (FATF) is an intergovernmental body established in 1989 on the initiative of the G7 to develop policies to fight money laundering. Since 2001 FATF is also looking into terrorism financing. The objectives of FATF are to set standards and promote effective implementation of legal, regulatory and operational measures for combating money laundering, terrorist financing, and other related threats to the integrity of the international financial system. FATF is a “policy-making body” that works to generate the necessary political will to bring about national legislative and regulatory reforms in these areas. FATF monitors progress in implementing its Recommendations through “peer reviews” (“mutual evaluations”) of member countries. It is the global watchdog for anti-money laundering & counter-terrorist finance. In June 2019, it updated its guidance paper for Virtual Assets Service Providers (VASPs) regarding the transfer of digital assets. There was an insertion of a new interpretive note that sets out the application of the FATF Standards to virtual asset activities and service providers. To apply FATF Recommendations, countries should consider virtual assets as “property,” “proceeds,” “funds,” “funds or other assets,” or other “corresponding value.” Countries should apply the relevant measures under the FATF Recommendations to virtual assets and virtual asset service providers (VASPs). Read more about the FATF recommendations here).

Question 12:
To what extent can blockchain be used to improve the privacy of healthcare?
Block.co team Answer:
Please refer to our previous webcast, blog, and articles for more information.
Question 13:
What is Blockchain technology in Shipping?
Block.co team Answer:
The shipping sector has been in the hold of phony maritime institutes charging exorbitant fees via agents, issuing certificates to candidates who do not have the imperative attendance, or those candidates who just pay the fees for the course and ask for the certificate. In view of these fake accreditations, the possibility exists that someone could be harmed or killed, and we could face any number of potential ecological disasters. Having the option to easily verify the genuine origin of a certificate by an approved maritime center is foremost for shipping companies to fast-track their operation and streamline their labor.
Question 14:
Different uses of blockchain other than cryptocurrency?
Block.co team Answer:
Please refer to our blog and glossary.
Question 15:
Upcoming trends in Blockchain concerning Advertising, Marketing, and Public Relations in the Public and Private sectors.
Block.co Team Answer:
Regarding the application of blockchain technology to media copyrights, please see Block.co use case proposal during the Bloomen Ideathon.

Question 16:
How to create a decentralized blockchain?
Block.co Team Answer:
An excessive number of individuals feel that blockchain is some supernatural innovation that makes up a decentralized system. In truth, this innovation only enables decentralization. Which means, it permits cryptocurrency to work in a decentralized way. Yet, it doesn’t give any guarantees that it will work that way. Along these lines, it’s really, some outer variables that decide genuine decentralization. Technology, itself never really guarantees it. That is the reason it’s a mistake to expect that if it’s a blockchain — it’s decentralized. From a technical perspective, both blockchains, centralized, and decentralized are comparative, as they take work on distributed peer to peer to network. This implies every node is individually responsible to verify and store the shared ledger. Both Blockchains utilize either a proof-of-work or proof-of-stake mechanisms to make a solitary record and they have to give upper and lower limits on the security and productivity of the system. For more information please refer to our infographic.
Question 17:
Dubai government Blockchain implementation progress?
Block.co Team Answer:
You can see more information here.
Question 18:
How Blockchain and IoT can be integrated to secure data being transmitted through IoT devices.
Block.co Team Answer:
You can read more about it here.
Question 19:
How can the Nigerian government use Blockchain to effectively implement its existing launched eGovernment master plan?
Block.co Team Answer:
Perhaps it can draw its attention to the initiatives of Dubai, Estonia, and Malta to prepare an implementation framework.
Question 20:
What impact is blockchain going to have in today world of business especially in the financial sector
Block.co Team Answer:
Please refer to our recent article titled Benefits of Blockchain Technology in the Banking Industry.
Question 21:
Is Blockchain Technology affect individuals?
Block.co Team Answer:
The social effect of blockchain innovation has just started to be acknowledged and this may simply be a hint of something larger. Cryptocurrencies have raised questions over financial services through digital wallets, and while considering that there are in excess of 3,5 billion individuals on the planet today without access to banking, such a move is surely impactful. Maybe the move for cryptocurrencies will be simpler for developing nations than the process of fiat cash and credit cards. It is like the transformation that developing nations had with mobile phones. It was simpler to acquire mass amounts of mobile phones than to supply another infrastructure for landlines telephones. In addition to giving the underprivileged access to banking services, greater transparency could also raise the profile and effectiveness of charities working in developing countries that fall under corrupt or manipulative governments.
An expanded degree of trust in where the cash goes and whose advantages would without a doubt lead to expanded commitments and backing for the poor in parts of the world that are in urgent need of help. Blockchain technology is well placed to remove the possibility of vote-apparatus and the entirety of different negatives related to the current democratic procedure. Obviously, with new innovation, there are new obstacles and issues that will arise, yet the cycle goes on and those new issues will be comprehended with progressively modern arrangements. A decentralized record would give the entirety of the fundamental information to precisely record votes on an anonymous basis, and check the exactness and whether there had been any manipulation of the voting procedure.
Question 22:
As Andreas Antonopoulos often says in his MOOC: ”is a blockchain even needed?” Ie. Are there better methods?
Block.co Team Answer:
In combination with nascent technologies, IoT, distributed computing, and distributed ledger technologies, governments can provide inventive services and answers for the citizens and local municipalities. Blockchain can provide the component to create a safe framework to deal with these functions. In particular, it can provide a safe interoperable infrastructure that permits all smart city services and capacities to work past presently imagined levels. On the off chance that there were better techniques, they would be researched.
Question 23:
Would any of this be also applicable to the educational sector (as part of the general public sector), and if so in which way?
Block.co Team Answer:
Yes, please refer to our Webcast on Education and our blog post.
Question 24:
Will we be able to get a hold of this recording upon completion of the meeting?
Block.co Team Answer:
Yes, here is a link to the recording of our webcast Blockchain in the Public Sector.
Question 25:
Was wondering if there are any existing universal framework in governing the blockchain technology?
Block.co Team Answer:
The short answer is NO, as this framework is currently being prepared in collaboration with the various Member States.

Blockchain in Healthcare: Bridging Trust in response to COVID-19

Blockchain in Healthcare: Bridging Trust in response to COVID-19
Link to our article: https://block.co/blockchain-in-healthcare/
There’s never been a better time to provide proof-of-health solutions in the healthcare system globally. While it’s difficult to comprehend the significance of the role that technology may offer in such difficult times, essentially it can be nailed down to its basic concept of simplifying work and coordinating activities, which could have helped avoid the worst crisis people have experienced in their lifetime. If the healthcare system would adopt technological innovations in the early stages, it could have benefited and saved many lives.
Although the healthcare system has traditionally been slow in embracing the latest digital solutions, just like many other industries, we’ve observed in a previous article how the Covid-19 crisis has accelerated the adoption of digital technologies on a global scale in several industries, including healthcare.
The latest webcast brought to the audience by Block.co hosted some high profile experts from the industry. They illustrated how blockchain especially, together with other technologies such as IoT, and AI could in the future help elevate prompt responses, and provide more secure and efficient storage of data, something that has been missed in the recent pandemic.
Ahmed Abdulla from Digipharm, Dr. Alice Loveys from EY, and Dimitrios Neocleous from VeChain were hosted by Georgina Kyriakoudes, one of the first in the world to hold an MSc in Digital Currency, founder of Dcentric.Health and creator of the permissioned blockchain ecosystem app called Aria, which aims to transform the patient healthcare experience by giving individuals full control of their medical records.
Blockchain’s benefits in healthcare are primarily identified by efficiency, specifically on the transfer of data, facilitation of goods transport via the supply chain, prevention of counterfeit medicines sale, secure storage, and exchange of data around ID management. The impressive projects all the webcast guests have developed in the industry enable just these features, from the digitization of patient records to storage and exchange of medical data as well as easier processing of funds.
https://preview.redd.it/7k85objjz1851.png?width=768&format=png&auto=webp&s=237293e731024ae8f50861682c434b04d7742e05
Ahmed Abdulla founded Digipharm with the idea of issuing tokens to allow patients to be in control of their medical records at all times. Moreover, tokens are issued to be paid for anonymously sharing personal medical data to help research; pay for healthcare based on how it has improved quality of life.
We have experienced a disparity in Covid-19 tests costs around the world. For instance, getting tested in Cyprus costs around €60 while in the US it may add up to a few thousand dollars. This is due to the way countries arrange payment setups from payers to providers. Blockchain empowers people to take ownership of their records and funds while providing transparency of processes. This is where blockchain can be robust, by increasing transparency and allowing the patient to secure money transfer and hold their own records”, stated Ahmed.
His work as blockchain advisor at the UN Economic Commission for Europe is helping set up standards for the blockchain ecosystem, namely how the system should be used safely, and in a way that benefits all stakeholders.
“I lead the blockchain and healthcare team at the UN center for trade facilitation and e-business where we developed a blockchain and trade facilitation white paper; the second phase will soon provide an advanced technology advisory board to advise private or public stakeholders on what’s the best technology to use. It might not always be blockchain, hence we first understand and then advise if the tech is right for them or not. Blockchain is clunky, expensive, and not always proper for the organization we work with”, continued the blockchain expert.
Most people may prefer public and permissionless blockchain because it has major advantages over a private and permissioned one. Transparency stands out for the way the ledger is shared and for due diligence becoming unnecessary as a result. This means costs are also cheaper, in the range of 100% lower. On the other hand, a public decentralized blockchain has a major disadvantage since no legal framework is laid out. This means uncertainty as there is still a grey area in the legal field that might create confusion.
Dimitrios Neocleous is Ecosystem Manager at VeChain Tech and directly supported digital and technological solutions provider I-DANTE with the creation of the E-NewHealthLife and the E-HCert for the Mediterranean Hospital of Cyprus. Both apps give patients control over their health records, improve medical data sharing, and increase hospital operational efficiencies by simplifying the process of visiting a hospital.
E-NewHealthLife is a complex ecosystem solution that starts from a patient’s visit to an emergency room. A card with the reason for a patient’s visit is issued; it gets time-stamped; the patient is sent to the waiting room; once the patient’s turn comes and the medical check is completed, the card is scanned and the visit is closed. Patients can digitally access all diagnoses that took place anytime at the hospital.
“The platform produces a digital health passport, which is an encrypted non-fungible card that patients can use to identify themselves automatically when registering at the hospital’s emergency room. The passport is stored within a mobile app called E-HCert, which keeps track of each patient’s medical data and can be shared as needed”, announced Dimitrios.
E-HCert App is a Covid-19 lab test electronic wallet and pushes up the results of a patient who’s been tested for COVID. It has been proven to be very successful so far; currently, 2000 people who transited through the Larnaca airport in Cyprus have downloaded the app. With time-stamped records, it’s able to provide data such as the day and time when the sample was collected, it offers immutability, security, and integrity of data.
https://preview.redd.it/kqq7jfgpz1851.png?width=940&format=png&auto=webp&s=2c9a121e0a4839125418db7ff61ae3957c3fff41
“Covid-19 showed a deficiency in healthcare. The spread of the virus could have been prevented if we had digitization of processes and transparency of data through blockchain, and transfer of data through an authorized share of records. An open permissionless decentralized blockchain helps bring ownership of medical records back to the patient, and that is not possible in a centralized system”, continued the VeChain representative.
Dr. Alice Loveys is EY ‘s healthcare blockchain leader in the US and has been at the forefront of emerging healthcare technologies for her entire career including being a pioneer in electronic health record adoption, health information exchange, and privacy and security.
She believes that “blockchain technology is like a plumbing system that brings clean and transparent trusted data that can be used. It’s not proper for a track and trace system as it invades privacy unless there is the consent from patients, in that case, blockchain transparent share of data would be extremely useful for medical research and testing”.
One problem we experienced during the crisis is the confusion that arose with divulged information and the frustration that comes with it. People do not understand anymore which information can be trusted; at first, it looked like COVID-19 symptoms were not dangerous, then it came out that they actually were. Masks were not useful at the beginning, then they suddenly became necessary.
“Blockchain could have prevented lockdown and economic crisis through data management in that a much faster response would have been provided to tackle misinformation because blockchain can help manage data from different sources”, continues Dr. Loveys. “Moreover, it’s a great way to protect the database. Instead of moving any private sensitive medical data through the more traditional digital systems, blockchain simply allows us to send an algorithm, encrypted data that safeguards the information. It’s not a great use as a database as it does not scale, therefore we would not be able to store information for billions of people in it. But for the data that is in the blockchain, using algorithms, makes it very convenient and secure”.
Another topic discussed during the webcast was the GDPR compliance for blockchain. GDPR (General Data Protection Regulation) was created before blockchain therefore it doesn’t account for decentralized technologies. Generally speaking, it all comes down to how the technology is used and what kind of data is incorporated in it. Timestamping data without invading anyone’s privacy, or timestamp of consented data, should determine no issue at all. This is what privacy by design stands for, taking human values into account in a well-defined manner throughout the whole process.
Block.co, powered by the University of Nicosia, is establishing itself as a global leader in the issuance of digital immutable and secure certificates timestamped on the Bitcoin blockchain. In the field of healthcare, it could include medical records, prescription issuance, insurance disputes, supply chain documentation, and any type of verifiable certificate that requires authenticity at its core.

How Blockchain is important for App Developers?

With newer technologies being launched each day, the tendency to the adoption of such leading edge engineering methodologies has been boosting every industrial area. The present market situation is such, in the event that you have to remain in the opposition, you have to get the new components of innovation. In the present market, if you have to stay in the competition, you have to pick up the new elements of technology. With startups failing to implement them, mobile application experts are struggling to keep pace with such huge numbers of techs simultaneously, exploring the massive growth of the current industry seems like a needful task.
Over numerous years, block-chain has held its status as a progressive thought with positive perspectives for multiple industries. This digital ledger system became popular during the times of cryptocurrency, and since then, been praised for its secure and reliable approach. Block-chain includes features like peer-to-peer payment architecture, decentralization, and security which makes it fascinating for developers. In the field of mobile apps, block-chain serves as a bountiful example, to build applications that are free from frauds, data leaks, and security threats.
Given the circumstances, blockchain is a concept of developers, the practical applications of which are in the initial stages of development. However, once understood, it holds a tremendous capacity to revolutionize the market. This game-changing technology is an important trend for the mobile app industry.

What is Blockchain Technology?

The reliable system operates by transforming data across network steadily so that no participants in the system are able to hack or tamper the blocks distributed. The blocks formed with a cryptographically line that helps to prevent a reformed process from an unknown member.
This blockchain holds distinctive features of distributed ledger technology, which safely stores data over the peer-to-peer network. Blockchain ledgers can involve land documents, loans, integrity, assets, and inventory etc. that can be stored strongly, where everyone has permission to see yet can’t change the results shared.

How Does Blockchain Work?

A blockchain is a string of numerous blocks stored together. Each time a transaction occurs, it creates a new block and is stored in the digital ledger system.
The following points state how blockchain works-
  1. A transaction needs to happen. For instance, you bought something from the XYZ store. When you have made a purchase, a block is created for it. Now, every transaction is grouped with thousands of other transactions in the block.
  2. The transaction should be checked. That is the job for a network of computers. These systems verify whether a transaction occurred from the XYZ store. When they confirm details of the purchase, it is verified.
  3. The transaction has to be stored in the block. When your transaction is verified, along with its dollar amount, digital signature, and the XYZ store’s digital signature, all this information is stored in the block. This block then joins the other hundreds and thousands of blocks, like it.
  4. The block should be assigned a unique code/hash. Once the information is verified, it is provided with a unique identifying code, the hash. Once hashed, the block can then be added to the blockchain.
Each new block added to the blockchain is public. That implies anyone can see it. Details like who when were the block added, where was it added, and by whom was it added is visible to the users of the blockchain.

Does this Mean, Blockchain has a Public Infrastructure?

It is true, anyone can see the contents of the blockchain. In a blockchain, you can also connect your computers to the blockchain, as nodes. Along these lines, every computer in the blockchain network receives a copy of every block whenever it is updated. It’s like your News Feed, when there is an update, you see the new fresh content at the top. So, when everyone can view each information, where does the security feature in blockchain come from?
In a blockchain network, there are millions of copies of the same block. This implies each copy of the blockchain is identical. So, it’s not possible for anyone to keep a record of such huge numbers of events. If any programmer needs to even manipulate the data of any block, they should change every copy on the blockchain network. Also, since you don’t have any knowledge of the users making the transactions, its data, to any hacker or user, is completely anonymous.
Only those who hold details regarding the digital signature or the username can access the information in a block and understand it. In this way hacking and manipulation is something that can’t occur in a blockchain environment.

Why is Blockchain a Popular Concept for Mobile App Developers?

Blockchain was first referenced in BitcoinTalk, the largest forum committed to Bitcoin. Many-a-times blockchain is said to give a steady base to cryptocurrency operations. In the previous few years, it has gained tremendous popularity, as a technology database.
But, what invited its attention in the minds of the developers was its decentralized nature and secure access. Since then, blockchain has become a fascinating idea for developers. Surely, it leads to transparency, yet it decreases fraudulent transactions, and data tampering activities as well.
Application developers are using this technology to make digital payments more accessible, simple, and secure. The nature of peer-to-peer transactions makes it an ideal fit for banking applications that needs such a type of technology.

Blockchain can Reshape the Future for Mobile App Developers-

Blockchain provides an edge to all those people who like to indulge in digital payments rather than cash to cash transactions.

But why is blockchain said to be fit in today’s market scenario?

digital transformations are at its top in the 21st century. Each business has a digital store, and an ever increasing number of customers are accessing the online platforms, to enjoy everyday services as well.
The digital world is providing the right momentum to blockchain technology and has evoke its need in the market. Blockchain is becoming increasingly popular for mobile payment apps because of its exceptionally secured features.
Let us see common types of blockchain-based mobile apps-
1. Apps for exchanging cryptocurrencies- This way, a person is totally in control of the digital resources and perform trading transactions using them. Such applications can be used for a wide range of payments and transactions.
2. E-wallets- E-wallets that can store all the digital assets and money. You can carry out the transactions through the application powered by blockchain technology.
3. Apps that help you to track rates- cryptocurrency trades, market dynamics and other scope of blockchain services.
4. Retails applications with a background of blockchain technology allowing customers to pay using cryptocurrency and bitcoin.
Now, let’s look why blockchain is apt for mobile app developers-

1. Enhanced data protection and privacy –

Blockchain is known for its great security. Developers can use this tech, to create multiple protection layers into their data. The private keys to this data will be just assigned to the users, making it impossible for anyone without a decryption key, to manipulate the transaction details. Since it is a decentralized system, it keeps a replica of each transaction on its computer network. This reduces the risk of data loss as well. Since hackers won’t have any knowledge about the user’s data and their private key as well, no fraudulent or unauthorized activities can take place.

2. Data transparency is an advantage too-

In a blockchain, the information about every transaction is visible to everyone. This implies anyone can see the details in real-time. However, since the data is stored by digital names and signatures, it is mysterious to others. They can see the transaction but will not know who made it (the real name and personal information). This way, no one can change the information in a specific block. Blockchain stores all the data in public view. Hence, if the user makes any manipulations to their data also, it won’t go unnoticed. Log for each change is made in this digital ledger system.

3. Secure mobile payments –

Introducing blockchain with mobile app serve one central motto, securing digital payments. Since more and more people are opting contactless mobile payments, protecting them with blockchain’s secure architecture seems to be a good idea. Numerous developers are focussing on coding a a more secure and affordable mobile payments app.
Blockchain will help these developers in securing the infrastructure of similar mobile apps. Also, since thousands of nodes function, it is improbable that they will crash simultaneously. This also reduces the downtime of such applications.

4. No need for passwords anymore –

To deal with any application, you need a password and login-id to authenticate your users. There are a lot of issues related to use of passwords. Anyone can track it and if you forget your password, getting a new one is a tedious task. With blockchain, users don’t need any password. The network of computers connected validates a transaction. Also, since blockchain is built on cryptographic codes like a hash that uses a digital signature to unlock all the digital assets for the involved parties, the authentication systems of such applications will become immutable, irrefutable, and incorruptible. This makes the process of accessing your resources, a seamless experience.

5. Improves the Efficiency of apps –

For each mobile application you use, you need a third-party mediator for it. In a blockchain, you do not need any party to finish the transaction. This improves the effectiveness and the speed of transactions. As indicated by a report, blockchain-based transactions are 10 times faster than the bank ones. In a blockchain, every transaction is approved by a computer. Hence, dissimilar to a traditional bank that takes days to settle a transaction, blockchain can do it in 2-3 minutes.

6. It reduces the cost per transaction-

In normal transactions that include third-party apps, blockchain removes any such middlemen. Also, the intermediate parties charge per transaction that reaches completion using their portal. Blockchain doesn’t charge any such fee and still gets the transaction completed. The eviction of such mediators reduces the transactional costs for both, the business and the users.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Beginners guide to Syscoin (SYS) and why you should be investing in this cryptocurrency in 2018

What is Syscoin?

Some have described Syscoin (SYS) as the Shopify, Amazon and Ebay of the blockchain world. Syscoin is a revolutionary cryptocurrency that offers near zero cost financial transactions, incredible speed and provides businesses the infrastructure to trade goods, assets, digital certificates and data securely. Syscoin isn’t just about money and trading, it has the ability to attract various business types thanks to its native set of features geared towards business on the blockchain. From eBay traders and High Street shops to Medical applications, Insurance and Gaming, Syscoin’s decentralized network benefits everyone!
Syscoin is developed by Blockchain Foundry (BF). BF provides blockchain technology based services, projects and products for a wide variety of use cases with the stated aim of disrupting markets by leveraging the potential of blockchain technology. Syscoin is mainly known to be the first cryptocurrency to offer a fully decentralized marketplace based on blockchain. What is lesser known is that this is only a part of what Syscoin offers.
With the introduction of Masternodes in February or March 2018 SYS will be transformed from just a ’marketplace coin’ to a completely ‘utilitarian coin’. The Masternode infrastructure allows the addition of decentralized databases and file storage, increased transaction speed to surpass POS/Visa/Mastercard capabilities, true Turing complete smart contract capabilities for unlimited business logic, sidechains, application layers and an identity layer. This will all be accessible through an API, rather than a new language, enabling nearly any developer to create any blockchain application they can conceive. This will usher in the next generation of blockchain applications - made for new or existing businesses - by conveniently offering everything available from the blockchain space today.

SYS Origin

The blockchain as conceptualized by Satoshi Nakamoto back in 2008 envisioned a peer-to-peer electronic cash network that would prevent double-spending. A year later, the blockchain became an integral part of bitcoin, serving as the latter's public ledger of transactions. Although Nakamoto's reference client mentioned a decentralized marketplace service, the subsequent implementation did not incorporate this due to a lack of resources.
Syscoin was initially described in a 2014 draft whitepaper that envisioned Decentralized Marketplace Creation, Decentralized Smart Contracts and Documents, Decentralized Certificate Issuance and Transfer, and Decentralized Data Storage and Retrieval, as among the services that it would offer upon its release.
Syscoin aimed to bring Nakamoto's vision of a decentralized marketplace back into the blockchain, among the other commercial-grade services it aims to deliver to clients. Other services that Syscoin plans to provide include secure data storage and transfer, and unique user aliases that link their owners to the services controlled by the alias.
The early Syscoin wallet was superseded by the release of Blockmarket Desktop 1.0 on September 12, 2017, marking the culmination of Syscoin's vision of a fully decentralized marketplace with a desktop GUI based on the blockchain.
The planned release of Blockmarket Web, a fully web-based version, and Blockmarket Professional in 2018 takes that vision one step further, as more advanced seller stores become a reality.

The Team

The Team that NEVER quits! Before the launch of Syscoin (Q3 2014), there was a presale ICO by Moolah (as a partner), which turned out to be detrimental for Syscoin. The project raised around 1,000BTC for development but the Syscoin Team only managed to access 250BTC which were used for price support. Moolah (Ryan Kennedy) absconded with the bulk of the ICO funds and the Syscoin team were left with ~30million Syscoin at a price around 400 satoshi. Even after this tragic event, the devs didn’t quit and continued to work on the project without stopping. The case against Moolah is still on-going. See the article from CoinDesk here: http://www.coindesk.com/uk-court-syscoin-injunction-moolah-750-btc/.
What is this detail telling us about the dev team? While some crypto projects are just scams and bring little to no innovation, they’ve proven that they are in it for the long term - ably demonstrated by the fact that they continued to work despite their funds being stolen. And now that hard work is beginning to pay off with the entire team going full-time for the first time in January 2018 and new developers being hired following VC funding for BF.

What is Blockmarket Desktop?

Building on the World's First Decentralized Marketplace, Blockmarket is the newest generation of Syscoin's Desktop wallet with a complete, state-of-the-art marketplace built-in where you can securely and reliably buy and sell any items you wish. Entire stores can be created directly through the marketplace where you can sell your own products or re-sell others’ products for commission. Use of blockchain technology eliminates middlemen, credit card fees, maintenance fees, downtime and political interference. Persons are literally able to buy or sell anything to anyone, anytime, anywhere on Earth! Blockmarket Desktop was launched on September 12, 2017.

Key Blockmarket Features

• Price Pegging to currencies such as USD, EUR, GBP, CAD, CNY and BTC
• Bitcoin and Zcash as payment options
• Arbitrated Escrow
• Encrypted Messaging
• KYC/AML Compliance
• Images
• Unlimited Inventory Items

Name Aliases

Wallet addresses for cryptocurrencies generally consist of a unique string of between 27-34 alphanumeric characters. Such an address isn’t easy to memorize. Although the addresses can be added to an address book within the wallet, Syscoin has taken the user's convenience one step further, allowing you to create a unique Alias for your wallet address, such as a name, title, or characters specific to a username. These can be used to send SYS from home, to a mobile wallet, to work, to friends, to common suppliers or to repeat customers easily, without requiring any memorizing, writing it down, copy & pasting or emailing yourself the address.

Digital Certificates

Using the cryptography of the blockchain persons can issue, authorize, and exchange digital certificates of any kind. With Syscoin anyone can issue provably-unique certificates with text or ASCII content to one or multiple parties on the Syscoin blockchain. These certificates can be authenticated by anyone via Syscoin’s cryptographic proof of work. This allows for the creation and free exchange of any kind of digital asset such as ownership certificates, warranties, receipts, tickets, certifications, diplomas, software licenses and more.

Integrated Exchanges

Integrated Crypto exchanges - Flypme and Changelly will facilitate exchanging 30+ cryptos for SYS, directly within the Blockmarket wallet.

Security Audit Verified

Blockmarket was successfully and independently security audited by Digital Boundary Group and was deemed low risk. Audit Results: [https://medium.com/@BlockchainFoundry/blockmarket-security-audit-results-and-next-steps-f69f94f149bf]

Blockmarket Web – (The Key to Mass Adoption)

BM web will bring SYS’s existing decentralized marketplace and all its features into a web-based version, enabling ease of use with a simple email and password login (grandma friendly) without any need for downloading a wallet or waiting for sync. Blockmarket web will be launched in February 2018.

Key Syscoin Developments

Masternodes

Ability for world-class transactions-per-second performance to scale-out with added nodes (theoretically 100k TPS per 1000 Masternodes, 300k TPS/3k masternodes, etc). In later releases, masternodes will also process smart contracts and facilitate sharded+encrypted offchain file-storage (with onchain anchors), among other touted functionality. They should also result in steadying the price movements - less volatility as holding will be incentivized

Smart Contracts

Scalable Ethereum Virtual Machine: Allows Turing complete smart contracts to be executed following the ethereum protocol at a much faster speed and at a fraction of the ethereum gas price.

Assets & Token Issuance

With its token issuance service, Syscoin allows anyone to create a custom asset token which can then be sent directly to anyone else on the network. This facilitates a variety of use cases including ICO token issuance, supply chain management, reward points, and loyalty programs.

Anonymous Transactions

Anonymous transactions: via mixing/shuffling at user-specified denomination. Afterwards, additional tech will be added in the near future which will further compound the degree of anonymity provided -Add ValueShuffle running on top of the masternode layer and you have the world's most advanced privacy tech in any coin. This brings true money fungibility to Syscoin and the missing link for true economic sovereignty. https://twitter.com/realSidhuJag/status/948588279540035584

Instant Send

Transactions can be sent and received instantly. This represents a similar sending capability as Dash, but is a step beyond- A type of backend node locking will allow an instantly received sum to be sent immediately, without delay, and without network risk of double-spend.

Blockchain – The Basics you should know

A community following banking, investing, or cryptocurrency over the last ten years may be familiar with “blockchain”. What is blockchain technology? It is a record-keeping technology behind bitcoin. In case of learning blockchain, you may have come to related terminologies- such as distributed, decentralized, and public ledger.

What is blockchain?

A Blockchain can be defined as a chain of the block that contains information. This technique is planned to timestamp digital documents so that it’s not possible to backdate them or temper them. The blockchain is used to the secure transfer of items like money, property, contracts, etc. This transfer is carried out without requiring a third-party intermediary like a bank or government. When information is recorded inside a blockchain, it is extremely hard to transform it.
The blockchain is a software protocol. Internet is necessary for running the blockchain. It is also called meta-technology as it affects other technologies. It consists of some pieces: a database, software application, some connected computers, etc. There are many wrong assumptions about blockchain. So just clear these points.

What blockchain is not?

⦁ Blockchain is not a Bitcoin, actually it is a technology behind Bitcoin.
⦁ Blockchain is the ledger to keep track of who owns the digital tokens while bitcoin is the digital token.
⦁ You can’t have Bitcoin without blockchain, but you can have blockchain without Bitcoin.

Need of Blockchain-

1. Time reduction:

Blockchain plays an important role in the financial industry. It does not require a lengthy process of verification, settlement and clearance also, so it allows quicker settlement of trades. This is because a single version of agreed-upon data of the share ledger is available between all stakeholders.

2. Reliability:

Blockchain affirms and confirms the identities of the interested individuals. This evacuates double records, reducing rates and accelerates transactions also.

3. Unchangeable transactions:

After registering transactions in chronological order, Blockchain ensures the unalterability of all operations. This means when any new block has been added to the chain of ledgers, it cannot be removed or altered.

4. Fraud prevention:

The concepts of shared data and consensus prevent possible losses due to fraud misappropriation. In logistics industries, blockchain is a monitoring system to reduce costs.

5. Security:

Attacking a traditional database is the bringing down of a specific target. Using Distributed Ledger Technology, each party can hold a copy of the original chain. So the system remains operative, even the large number of other nodes fall.

6. Transparency:

Changes to public blockchains are publicly viewable to everyone. This gives more transparency, and also all transactions are changeless.

Versions of Blockchain-

1. Blockchain 1.0: Currency

The implementation of distributed ledger technology prompted its first and obvious application: cryptocurrencies. It is used in currency and payments. It permits the financial transactions carried out through blockchain technology. Bitcoin is the most common example in this segment.

2. Blockchain 2.0: Smart Contracts

Smart Contracts are the small computer programs that work with the blockchain. They are the computer programs that automatically executes, and check conditions that are defined earlier like facilitation, verification or enforcement. It is used as an alternative for traditional contracts.

3. Blockchain 3.0: DApps:

DApps is an abbreviation of decentralized application. It has their backend code that runs on a decentralized peer-to-peer network. A DApp can have frontend code and user interfaces written in any language that can make a call to its backend, like a traditional Apps.

Structure of Blockchain-

Basically, blockchain is a public digital ledger. This ledger records transactions across computers. What makes it successful and popular? The answer is, it is centralized and distributed. Let us consider one example- Let’s say that person A wants to send some Bitcoins to another person B. To do that, they must know what is wallet address of person B. This wallet address is usually similar to an email. But we use this wallet address to send money rather than emails. Once the money is sent, it must be verified by every node. This node is a part of the blockchain network to get to person B’s wallet. In this transaction, every computer on the blockchain makes a transaction record and also saves it. Hence rather than having one transaction record kept in a bank, there are thousands of records stored in thousands of computers.
You might not like the thing of having your transaction records available on so many computers. This issue is resolved by making transactions mysterious. This is achieved by using cryptography. Hence cryptography is vital part of this technology. In case of changing transaction records, it would have to access every node ie., computer. But this is impossible. Blockchain miners are the people dedicated to devices and blockchain. Devices of these blockchain miners are the nodes on the network that validate transactions and store it in distributed ledger. These miners are get rewarded in bitcoins for their services.

Use Cases of Blockchain-

1. Government sector-

Blockchains are used in government sector for digitization of document/ contracts and proof of ownership. It can also be used for Tele-attorney service, registration and identification, IP registration and exchange, Tax receipts Notary service and document registry.

2. Markets-

Blockchain is used in marketing for billing, monitoring and data transfer. Also it is useful for Quota management in supply chain network.

3. IoT-

Blockchain technology is used in IoT for agricultural and drone sensor networks, smart home networks, integrated smart city, self-driving cars, robots and digital assistants etc.

4. Health-

Electrum Personal Server - The best way to connect your hardware wallet to your full node

Electrum is a popular bitcoin wallet, but it is not a full node wallet as it synchronizes itself using third-party Electrum servers. The servers must be trusted to verify the rules of bitcoin, they can trick Electrum wallets into accepting fake bitcoin transactions which, for example, print infinite money. Bitcoin's security model requires that most economic activity is backed by full nodes. The Electrum servers must also be trusted with the user's privacy, as wallets send all their bitcoin addresses to the server. Spying on wallets is not much more complicated than simply grepping the server logs. Electrum wallets by default also connect to servers using their own IP address, linking it further to their revealed bitcoin addresses.
A way to avoid these problems is for users to run their own Electrum server and connect their wallets only to it. But this requires significant resource usage: the full unpruned blockchain, transaction index and an extra address index, as well as more RAM and CPU usage compared to just a full node. Servers are not well suited to being shut down and started up again, they are typically always online.
Electrum servers store a database of every bitcoin address ever used, which is inherently not scalable. This is resource-intensive and therefore pushes users towards centralized solutions. An alternative way would be to store only your own addresses and transactions.
Introducing Electrum Personal Server; an implementation of the Electrum server protocol which fulfills the specific need of using the Electrum UI with full node verification and privacy, but without the heavyweight server backend, for a single user. It allows the user to benefit from all of Bitcoin Core's resource-saving features like pruning, blocksonly and disabled txindex. All of Electrum's feature-richness like hardware wallet integration, multisignature wallets, offline signing, mnemonic recovery phrases and so on can still be used, but backed by the user's own full node.
An alpha version of Electrum Personal Server can be found on the repository: https://github.com/chris-belcheelectrum-personal-server
Before using, the wallet user must configure Electrum Personal Server with their master public key and those addresses are imported into Bitcoin Core as watch-only. If the wallet contains historical transactions then it must be rescanned. One of Electrum's motivating features is "instant on", which is therefore traded away when using Electrum Personal Server in return for full node verification and privacy. Although if a brand new empty wallet is created there is no need to rescan. A script like Electrum Personal Server is also well suited to use private transaction broadcasting tech like dandelion or broadcasting through tor.
Using Electrum with Electrum Personal Server is probably the most resource-efficient way right now to use a hardware wallet connected to your own full node. People who make use of Blockstream Satellite could use it to have an off-the-grid node connected to Electrum if that is their preferred wallet. In the situation of a traveller staying a cheap hostels, they could sync their node every couple of days to download recent blocks and use Electrum. Hopefully this software can be part of the plan to get full node wallets into the hands of as many people as possible.
The same kind of ideas could be applied to other lightweight wallets. For example a full nodes can run on smartphones with pruning and blocksonly, then a similar script would allow the user to connect their Samourai Wallet, Breadwallet or GreenAddress app to their own full node.

PortBitX.COM White Paper

White Paper


We are a free society united by the basic idea of ​​freedom and justice, separated from geographical, religious, ethnic and gender prejudices, we reaffirm this document, and we promise to protect freedom and benefit people always and everywhere.

PortBitX Project

The PORTBITX project team creates a service whose main idea is to provide a mobile and convenient system where users and cryptocurrency owners can receive a wide range of services.

1 The essence of the project

The project team asks you to support the creation of a high-tech, simple, convenient and honest ecosystem for people who need to protect their rights and freedoms and use the right to be anonymous and financially independent.
The mission of the project is to create a service for storing and exchanging cryptocurrency assets, and also to become a tool allowing to conduct trading operations regardless of geographic location or language skills.
Advantages of the project:

2 State of affairs

Owing to ignorance or low awareness of people about the nature of cryptocurrency assets, cryptoindustry is mythologized in modern society. This applies to both ordinary people and officials in authority.
As a rule, in the minds of people there is more confidence in traditional financial instruments than in technology during their development, for example blockchain (the inability to change the information block / blockchain chain).History knows many examples when the governments of different countries, guided by the interests of their citizens, inadvertently led to the decline of advanced civil initiatives. This time is a period of complex formation of crypto-economics and state relations, which is still in the making.
The project that we present to your attention has no borders between countries and peoples. And we, a group of enthusiasts, would very much like to cooperate with large government organizations. But, to our deep regret, the states currently at the stage of formation of their cryptocurrency policies make mistakes that negatively affect the crypto community.
The market of cryptocurrency assets, which has a ten-year history of development, is very sensitive to various statements by officials. However, unqualified criticism cannot withstand the global trend. And no one can stop the future.
With all the desire, time does not stand still, technologies themselves continue to evolve, new technologies, new projects, new views that can be upgraded in the distant future, as well as processes of government and regulation themselves, to introduce innovative elements into them. We do not expect the distant future, and many tools are available now. And we have something to offer you.
This is especially relevant against the backdrop of the upcoming global financial crisis, with the inevitable decline in trust in state financial institutions; cryptocurrency have high chances of becoming more popular in the absence of other technological alternatives.
As we noted earlier, there is a lack of awareness among people about Blockchain technology and cryptocurrencies. These technologies are extremely undervalued, since there is much more benefit in them than one can imagine.
In the cryptocurrency assets industry itself, there are fraudsters at this time who are trying to steal or fraudulently get your money.
At the same time, there are many honest crypto projects that can not be realized due to stereotypes of perception of them as fraudulent. Objectively, they could be judged by their work and projects that have been successfully implemented. In principle, it is necessary to be cautious in terms of investing in any projects, even if they are guaranteed by reputable people or companies. No reputable person or company can match the level of guarantee and security of your assets, as in the Bitcoin blockchain.In any case, the decision to invest is yours, not imposed by restrictions, and the responsibility lies with you.
According to Road Map, we intend to fulfill all the terms of the agreement with our participants.
We do not promise you a high yield of our tokens, we put all our experience into the overall welfare of the project and each user. There will be no delisting on the service until the community votes for the opposite.
Our risk is collective. We urge you to make an adequate and balanced choice, instead of imposing any other opinion on you. We are not supporters of aggressive marketing.
There are many cryptocurrency assets and it’s difficult for a regular user to store and exchange them, as well as use them in everyday life.

3 Disadvantages:

These are problems that affect users and cryptocurrency in general.

4 Solution

The PORTBITX project guarantees compliance with all of its obligations and user rights.
We integrate community communications into our PORTBITX service.
Users are offered the following functions:

5 Competitors

Direct market competitors are all decentralized and centralized services related to the purchase or sale of cryptoactive assets, as well as services that provide storage services on a cold or hot crypto wallet.
More than 16 thousand services and more than 2 thousand types of cryptocurrency assets.
We have the opportunity to offer our clients a reliable and open service for the storage and exchange of cryptocurrency assets.
The main competitors are such large cryptocurrency exchanges like Binance, Bitfinix, Bitrix, etc. These multibillion-dollar projects that can affect the entire market and regulate pricing also have millions of crypto communities.
This position is deserved by their work. There are, of course, disadvantages associated with the opacity of their activities, unlike us, but in general they play an important role in the cryptoindustry. Their trading volumes are impressive and inspiring, their mistakes lead to sharp price fluctuations in the crypto market.
There are still crypto exchange. In comparison with the leaders, they are significantly inferior in the volume and number of users. These exchanges include the bulk of all crypto exchanges on the market.
There are also exchange services on the market that allow you to exchange fiat money for cryptocurrency assets. Most often the commission is quite expensive. For example, they can range from 1% to 20%. Such a high commission can be explained by the fact that the locations where buyers and sellers are located have government restrictions or are prohibited.
In addition to all of the above, there are closed groups in social networks or instant messengers. There, people discuss and agree on the price and method of payment. Commissions are often not high from 0% to 5%, but one should not hope that such operations can be safe, since personal meetings are always accompanied by a risk to life or health.
Exchange transactions in the onion network may have no guarantees at all that the transaction will be successful. In deep web, everything works on credibility / reputation, and the higher the seller’s rating, the higher the likelihood of a successful outcome of the transaction. In the same place, you can sell tagged or stolen cryptocurrency assets. For this, there are special mixing sites to hide the criminal trail. These types of exchange operations are the most unreliable.
For this reason, one of the safest types of exchange operations is large centralized cryptocurrency exchanges. Such centralized services, sometimes using their position, impose their own rules, which leads to a loss of users’ material values.
PORTBITX is designed to empower cryptographic protection for maximum convenience and simplicity, as well as to protect the funds and personal data of users.
PORTBITX connects all cryptocurrency assets into one transport hub and creates highly efficient curvilinear isolation of the currency to make cryptocurrency as safe and close to people as possible.

6 Segment

A registered user of the PORTBITX portal can be any person supporting the general idea of ​​a free society. Our users are anonymous and financially independent, with the right to vote and the right to receive common incomes obtained by the operation of the portal and the activity of the crypto community PORTBITX.
For whom we create a service:
It can be ordinary housewives, entrepreneurs, unemployed, self-employed, freelancers, people who invest in the future, wealthy investors, etc.
One of the advantages of the service is anonymity, which gives anyone the right to save and earn around the world online, without fear that tomorrow they will be forced to pay some strange fees or licenses.
Service users are interested in the distribution and real use of cryptocurrency.
Self-regulating community PORTBITX, respecting the rights of all project participants.
Service users are:
For trust in the trade service there will be a seller rating for all types of goods and services presented. There will be a book of reviews about each seller, where each buyer has the right to leave a review about the product or service. This scheme is actively used in Darknet. The basic principle: the more positive reviews, the more trust. Each seller values ​​his authority and thus provides the best possible product or service. The expression “customer is always right,” works because no one wants to lose their customers.Currently, according to blockchain.com, there are used 34 million people who hold their funds in Bitcoin. The remaining number of users is difficult to calculate, but according to our modest calculations, there are at least 2 times more other users in any other currency.
This suggests that there is still a great demand on the market for services of safe storage and exchange of cryptocurrency assets.

7 Bounty

Bounty is a reward of users for PR-activity: subscriptions on forums, maintenance of topics in local language versions, translation of documents into a local language, publications in social networks, blogs and so on.
The terms of the bounty are published in the user profile of the section Terms and conditions of the bounty campaign.
To participate in the bounty campaign, bounty hunter, you need to register on the site PORTBITX.
You agree to the terms and conditions of the Bounty campaign if you register and do Bounty Hunt.
Tasks and their description are listed in the special section “Bounty Hunt”.
Each task is individual and has its own characteristics, so bounty hunters are invited to carefully study the conditions of each task.
Rewards are described in each task separately. The results of remuneration depend on the correct execution of the task.The remuneration is charged to the user’s personal account in the personal account.
There is also a payment history for completed tasks.
After the last fundraising stage, all information will be deleted in favor of the anonymity of users. We will also delete information about site visits and personal information that was required to specify to receive a reward. In the case of a request by third parties for data, we did not have information that could harm bounty hunters.
The bounty budget is 14,325,893 PORTBITX.
The distribution of tokens in stages is as follows:
Stage 1 – 6,325,000 PORTBITX;
Stage 2 – 4 000 000 PORTBITX;
Stage 3 – 4 000 893 PORTBITX.
Distribution of PORTBITX tokens:
If the ICO is not successful, the invested funds will be returned to investors, and the reward for bounty hunters will be canceled.
For this reason, we regulate and monitor the social activity of the bounty hunters so that the conduct of all ICO stages is successful.
For bounty campaigns, an application to the technical department is provided in order to correct them immediately in case of errors, as well as to assist the bounty hunters in carrying out their tasks.
We are building a healthy community, so we ask that the personal opinion and evaluation of the project PORTBITX of each participant be objective and adequate.
Each participant in the campaign bounty is our representative, and for us it is important to have a clear understanding of the face of responsibility and benefit that the community carries out.

8 Market

On the market there are many companies involved in the exchange and storage of cryptocurrency assets.
The number of such services is more than 16,000 and this is not the limit, but it is precisely in the face of fierce competition that truly unique and competitive projects are born.
This market situation motivates us to create a truly useful and necessary service in order to make the range of our service available to a wide range of people.
Recently, according to Google Trends, interest in cryptocurrency has fallen significantly. Now interest has rolled back to the area of ​​2016-17.
Cryptocurrency industry continues to function and develop. Now on the blockchain, you can create your own e-government, your own elections and currency, everything is limited only by the imagination of all industry participants.
The ecosystem is actively developing for the use of cryptocurrency in trading operations. Governments and regulators in different countries are seeking greater transparency in the cryptocurrency industry.
Some, such as the Japanese government, license and regulate crypto exchange and services. In Japan, cryptocurrency has long been accepted as a means of payment in many outlets. In states with despotic regimes and an unstable economy, one of the few tools for the preservation and enhancement of assets is Bitcoin, for this reason in these countries the rate can differ greatly from the average market rate.
The financial crisis and the instability of markets around the world continues to cause fear among people. In some countries want to ban circulation of dollars. Gold cannot be bought in the usual way and owners may experience some difficulties in working with it. Gold has long ceased to be a means of payment.
The priority for us is the safe storage of cryptocurrency assets, maximum user convenience and integration, the popularization of the cryptoindustry in everyday life.
In order for cryptocurrency assets to be used and an integral part of human activity, we want to form a stable market. At the moment, the capitalization of the entire market for a number of years fluctuates in the range of $ 100– $ 300 billion. The range of exchange operations ranges from $ 13-16 billion per day. The number of cryptocurrency assets represented on the markets is more than 2000 types.
The dominance of the main cryptocurrency Bitcoin is in the range of 49-52% of the entire market.
The tendency to reduce the main quotes scares potential investors, but this is not a reason for surrendering positions to a multi-million dollar audience of crypto enthusiasts. The reason why people continue to create new projects and new systems for exchange and transactional systems is the benefits they bring to humanity. In the market, as well as around the world, there are many unscrupulous developers who need to fight.
We are engaged in creating and securing the credibility of the cryptoindustry so that the user can choose a reliable service or network, and not imposed by anyone. This is one of the fundamental aspects of a free community. The right of choice for the user, “the client is always right” is an integral part of the philosophy of the PORTBITX project. By the level of their responsibility, transparency, advanced thought, innovation, in the future, the work of PORTBITX will judge all cryptomir. The better we, PORTBITX work for the good of society, the more trust we have and the more users use the PORTBITX service.
PORTBITX is part of a new culture, part of an ecosystem where the core value is reputation based on trust. This is a project where reputation is more important than money, and utility and service to people is more important than ostentatious hospitality and external gloss, and the safety of the assets of our project participants is more important than our profit indicators.
Capitalization is growing steadily from year to year.
At the beginning of 2017, the capacity of the crypto market was around $ 19 billion. Now capitalization has grown to $ 200 billion. The growth is colossal, but the market is still young and there will be many more challenges on the way to which all market participants will have to respond. And our participants will be the most prepared.
The number of new blockchains and new projects is growing, and the number of participants in the crypto market is also growing. As a result, the attitude of people to the cryptoindustry is changing for the better, just like the cryptoindustry itself.
In 2017, the known cryptocurrency assets were less than 800 species, but now their number has grown. Now on the market represented more than 2,000 species.
Not all assets are honest, there are those whose purpose is to obtain short-term profits, which badly affects the reputation and trust in the cryptoindustry. But, if we recall the story of the beginning of our amazing world, then the price for one Bitcoin was $ 0.00000003. Since then, the situation in the cryptoindustry has changed dramatically.In the future, the cryptoindustry market is waiting for great popularity and that is why reliable and honest services for the storage and exchange of cryptocurrency assets like our project will be needed.
Sharp volatility is such because the market is relatively young and has not reached even a tenth of its potential and capitalization. Therefore, the time in which we live is just a starting point. The world has already passed the Rubicon and there is a long and interesting road ahead.
The potential market we can serve in the future is more than one billion users. Now this market is slightly less than 50 million users.
Experts expect that in the future cryptocurrencies will replace the official fiat money.

9 Product

PORTBITX is a digital portal for storing, exchanging and trading cryptocurrency assets, as well as a platform for selling goods and services for cryptocurrency.
The service is managed by the community by voting. Voting topics are offered through a special application in the voting section.
Service has three main areas.
Secure storage of cryptocurrency.
Secure storage of over 1500 different cryptoactive assets. Safety is ensured by safe cold the repository.
The service itself is not directly connected to the repository to prevent the penetration of potentially dangerous programs. The security of user data in the service itself is protected by a local block chain. The entire database and operations are recorded on the principle of a distributed registry. Hacking one server should do this with hundreds of others located in different places. Mining in this block chain is not performed because all the costs of maintaining such security are borne by the service itself.
The PORTBITX development team is fully responsible for the security of cryptocurrency assets and for the operation of the service. One of the most vulnerable links in the safety chain is the human factor (concerns not only users, but also developers). For this reason, it is necessary to double-check scenarios, conduct stress testing and carefully select personnel.
Exchange
This is a portal for exchanging all available cryptocurrency assets for any other. The number of assets available on the portal will be recorded in the blockchain for a reliable display of the volume, the number of wallets, users and information on all the operations performed since the launch of the main network will also be indicated in the blockchain.
Any cryptocurrency asset can be exchanged for any other if it is in demand. The market decides for itself how and in what to trade. All exchange orders will be visible in online charts. Potentially, we will add more than 2,500,000 pairs to the portal, but not immediately, but in parts and as each cryptocurrency asset is checked. Also the choice for coins or tokens will always be behind the PORTBITX community. After each vote, all results will be published in the section “Voting” and on the official website of the service.
The portal has a convenient interface and an open registry, i.e. users will be able to monitor and control the network with developers. Also, with certain voting results, there may be additions to the network.In the future, we want to release the service in free navigation and stop controlling the network. If we succeed, we will open source code and create jobs for miners.
Marketplace
Marketplace is valid for the sale of services and products for cryptocurrency. High-quality and convenient service. All transactions on the Marketplace are recorded in the main register of the local blockchain. A wide range of products available advertising products and services, two types of payment (with a guarantee and with a reputation) to choose from.
The following portal functionality:
Voting / referendum
An important component of the PORTBITX portal is voting / referendum.
A variety of topics and surveys can be submitted to a vote, directly related to the PORTBITX community and the portal itself. For example, changes in tariff rates, adding new tokens, adding new services and additions to the service.
The right to vote is the right to decide the fate of the community, the right to find the best solution to the problems, the right to be free, honest and fair.
One voice is 5000 PORTBITX. (this limit can be lowered if the community decides on a general vote).
Since tokens can be sold on third-party services, they cannot automatically take part in voting. Also, all available tokens on the portal should be frozen for a period of voting that lasts no more than 24 hours, starting at 00:00 Central European Time.
Tokens are frozen through the user’s personal account in the voting section.Persons who do not have enough tokens for voting, but having the right to profit PORTBITX have the opportunity to see the voting results, as well as to make their proposals for the next vote.
Persons who do not have enough tokens for the right to vote and the right to profit will have the opportunity to group together for collective voting.
Results and coverage of all voting results will be immediately published after the end on the portal’s main page.
A vote is considered legitimate if a quorum gains 65% of the total number of votes. The decision on the outcome of the vote can be made if the number of those who agreed to 100% of those who participated in the vote is 60%. Voting can be repeated if uncrowded by a majority. In this case, the proposal will be revised. The deadline for a deferred vote may pass unplanned within two weeks after the end of the first vote. If, in the second ballot, the majority of votes will also not reach the bulk of 60%, then this issue will be postponed or canceled and will not be considered within the next 6 months.
The right to vote is not just an opportunity to influence the portal, it is the will of the community that developers must obey.
The right to profit
The right to profit is obtained by freezing tokens through the user’s personal account for a period of at least one month. The number of tokens needed to make a profit of at least 1000 PORTBITX.
The calculation of the distribution of profits are as follows.
All profits from all services provided by the service for a certain period of time in the tokens in which the activity was performed are distributed in relation to all community members who have frozen the tokens directly on the service portal. The profit is distributed in the same currencies in which it was received on the service.
In the event that the frozen asset of the PORTBITX tokens is defrosted ahead of time, then the profit it receives during this period will be distributed among the other participants whose tokens remain frozen.
Participation in the project is proved by deed and rewarded, in all fairness.
All profits, namely the estimated profits of users during and at the end of the period can be tracked and seen in the registry on the main page accessible to all interested parties.
PORTBITX developers do not hide revenues and honestly share them with the community.
Each user has the opportunity to check the registry and find their own account.Maximum openness and transparency is the key to trust and success of the service.

10 Road Map

11 Economy and Demand

All information on the movement of funds and their spending will be published on the official website of the company in a special reporting form.
All actions performed by PORTBITX will be covered in the news section of the company’s website.The voting results and the timing of their holding, as well as the topics discussed for voting will be in the user’s personal account in the “voting” section.To date, only about 80 million people have a cryptocurrency, store it or use it in payments.
Now there’s practically no way to find a person who hasn’t heard about bitcoin or blockchain at least once. The cause of mistrust is people who undermine the true face and good intentions of the founding pioneers of the cryptoindustry.
The market is too small and hypervolatil, but this trend will continue only for some time, until the total market capitalization reaches 1 trillion. USD This milestone will further open the way to even more people who want to be part of the crypto world. A larger number of participants will make this market more stable and less prone to hypervolatility.Unfortunately, there are many scammers and individuals who undermine the basis of the industry, and its usefulness. Therefore, the PORTBITX development team creates a service safe for the safety of users’ funds.
According to statistics provided by Blockchain.com from March 2018 to February 2019, the number of new users who registered new cryptocurrency wallets increased from 23 million to 33 million. Based on the data obtained, it can be concluded that there is a need for reliable storage of their cryptocurrency assets.
The year 2019 is a preparatory platform for an even larger number of users, so we decided to create a portal for the ecosystem of the cryptocurrency industry.

12 Project Team

One of the important factors in the decision making for an investor is the transparency and fame of the team that works on the project. An investor can check team members, evaluate and decide on investments. The knowledge and experience of the team is a kind of guarantee that the project will be implemented, but as is often the case in real life, this may be far from reality.
In the cryptoindustry, nothing can be 100% sure. Any ICO defaults to scam.
If you have doubts about our decency, we suggest investing a small amount.
By collecting the minimum amount, we will demonstrate in practice that we are credible, because our goal is to benefit the community.
Founders of PORTBITX
Co-founder and Technical Director Steve Man
Co-founder and CEO of CharleySJ
Director of Marketing and Public Relations MAD Phoenix
Director of Methodology and Legal Support at PenA

13 Investments

The minimum capitalization of the project at the first stage is 1,450 ETH.
The minimum total capitalization of the project will be 56,000 ETH.
The maximum capitalization of the project can reach more than 160,450 ETH.
Tokens will be issued in the amount of 143,258,928.57142.
Share will be up to 8 decimal places. ICO is calculated in three stages.
We create a product that meets modern requirements and market challenges. Additional issue is not provided. After the last stage of the ICO, all assets not sold will be destroyed.
We initially limit the emission of tokens in order to avoid a large amount of excess asset. Being part of the PORTBITX community means having the privilege of voting and profit of the service. And that means – to understand the idea and share the philosophy of the cryptoindustry and with full responsibility to approach the decisions that will affect the community.
The opportunity to receive a bonus will be among the participants of the Bounty campaign and among ICO investors, but by decision of the crypto community.
Return of investment will be carried out in several ways.
By obtaining distributed service profit
Due to the possibility of selling a token at the market price, which can be ten times higher than the initial cost.
The token will be based on the ERC20.
The predicted price of a token at the end of an ICO can be about $ 3.7.
The projected service revenue for the first year may be more than $ 500 million.
Pricing can be changed if there is an ETH price manipulation before release.
The news about the name and the release of tokens will be announced in the official news, so you should not give in to manipulation.

14 ICO Features

Jurisdiction: Blockchain
The number of tokens is 143 million.
On ICO 80.225 million
On a bounty campaign of 14.3 million
The developers and founders of 34.382 million, and the maintenance of the service 14.3 million.
Distribution will be carried out automatically.
The following fundraising is provided:
Stage 1 – 1,450 ETH
Stage 2 – 10,000 ETH
Stage 3 – 149,000 ETH
Pricing and limits
1st stage ICO
1 PBX = 0.002 ETH
1 ETH / 0.002 = 500 PBX
5 ETH / 0.0015 = 3 333.33333333 PBX
10 ETH / 0.001 = 10,000 PBX
Rules of the first stage:
The minimum amount to raise funds 1,450
Price is limited to pricing policy.
Bounty company 6 million

10 ETH / 0.002 = 5,000 PBX
3rd stage ICO
1 PBX / 0.004 ETH
0.5 ETH / 0.004 = 125 PBX
1 ETH / 0.0035 = 285.71428571 PBX
5 ETH / 0.003 = 1 666.66666666 PBX
10 ETH / 0.0025 = 4,000 PBX

15 Legal aspects

Placement of the company – Blockchain. This is due to the fact that we approach the project with full responsibility and are aware of the consequences of our actions, as well as due to pressure from some states and their unfriendly policy to the cryptoindustry.
Also, the service will not be present fiatnye currency, as their existence is not combined with the philosophy of our company. We will temporarily not specify the location of the company, as well as disclose the names of developers for the safety of their rights to life, health and freedom.
Since we consider ourselves a free community, some data for the sake of security for the sake of this freedom will be hidden from outsiders.
We guarantee a refund in case of unsuccessful first stage at 100% minus the miners commission.
This is important because the tools incorporated in the first stage are necessary for creating the kernel and the subsequent imposition of software modules.
We considered options for direct investment in the project from private investors, but since these investors could influence our strategy and policies, and since they could take some of the functions from the community, we decided to invest in our project as a community by Ico.
The risk of investing in our project, of course, is great, but we want to build a really useful service for the industry as a whole and for each user of the service separately. Therefore, we enable the community to judge us by our work.

#1 Complete Step-by-step Blockchain Mobile Wallet Development Using Xamarin Uploading Documents and Verifying on Blockchain How to Check Bitcoin Transaction Status on Blockchain  Check Bitcoin Pending Payment Bitcoin Q&A: Data integrity and validation of keys How Does Bitcoin Work ? (The Basics) - Beginners Guide To Bitcoin - How To Get Started With Bitcoin

Imagine a blockchain-like protocol that promises to remove what is seen as the two biggest deficiencies in blockchain: inefficient mining and soaring transaction fees. IOTA is working on a fix. Cryptocurrencies (including Bitcoin) instead have a built-in scarcity due to their source code which effectively limits the ultimate cumulative number of units which can be created. Bitcoin, for instance, is limited ultimately to 21 million bitcoins and this finite supply makes them similar in this respect to gold or silver. I too tried to initialize a block index and chainstate database on my x86 system and then copy the files over to a Raspberry Pi. Since both systems are Linux, 32-bit, little-endian, I figured there would be no differences in the on-disk format. However, this is apparently not so. When Bitcoind starts verifying blocks, it immediately starts complaining about missing transactions. However, using ... Each block in the Bitcoin Cash blockchain contains a summary of all the transactions in the block, using a merkle tree. A merkle tree, also known as a binary hash tree, is a data structure used for efficiently summarizing and verifying the integrity of large sets of data. Merkle trees are binary trees containing cryptographic hashes. The term ... Bitcoin Core stores the blockchain metadata using Google’s LevelDB database. Each block is identified by a hash (SHA256 of the block header). Each block is linked to the previous one (parent) using the previous block hash field in the block header. The hash sequence links each block to its parent creating a reverse chain to the first block created (genesis block). Although each block has ...
