White Paper, Miner, Pizza … | "Old Objects" in the Cryptocurrency Museum

White Paper, Miner, Pizza … |
https://preview.redd.it/giu1ssilga151.jpg?width=900&format=pjpg&auto=webp&s=41510785ccdc0d99544ec74229f62427d1c0ce3e
Museum has played the role of a time recorder. Talking about bitcoin, more than ten years has passed since the creation of it. Although it is uncomparable to the stock market with a hundred years of history, during the ten years, in the different stages of the development of bitcoin and blockchain have continuously poured in geeks, miners, speculators, newbies, leaving keywords such as sudden rich, myth, scam, belief, revolution, etc.
There are also many “old objects” with stories in the “Museum” of the cryptocurrency realm. On Museum Day, let ’s review the stories brought by these “old objects”.
The First Digital Currency White Paper — Bitcoin White Paper
On Oct. 31, 2008, Satoshi Nakamoto released the Bitcoin white paper — A Peer-to-Peer Electronic Cash System in the cryptographic mail group where he belongs, and Bitcoin was born since then.
A white paper is a document that explains the purpose and technology used in cryptocurrency. Usually a cryptocurrency uses the white paper to help people understand what it provides, and it is also an important information channel for investors to understand a project. Therefore, the level of the white paper affects people’s confidence towards the coin.
In a word, in the cryptocurrency and blockchain industry, the value of a white paper is equivalent to that of a standard financing speech. The white paper plays a vital role in this emerging market.
The First Public Bitcoin-Physical Transaction — Pizza
Since Satoshi Nakamoto mined the Bitcoin genesis block on January 3, 2009, Bitcoin has only been spread among the small crowd and has not realized its value.
Not until May 22, 2010, Bitcoin enthusiast “Laszlo Hanyecz” bought a pizza coupon worth $25 with 10,000 bitcoins. This is the first public bitcoin-physical transaction. Bitcoin has its price with 0.3 cents per bitcoin.


This day has also become the famous “Bitcoin Pizza Day” in Bitcoin history. Bitcoin as the imagination of the financial system has more practical significance. The tenth anniversary is coming. How will you commemorate it? Will you buy a pizza?
The First Digital Asset Exchange — Bitcoinmarket.com
After the birth of Bitcoin, in addition to mining, the only way to get Bitcoin in the early days was to conduct transactions on forums or IRC (commonly known as Internet Relay Chat). However, this method involves both long transaction time and great security risk.
In March 2010, the first digital asset exchange — Bitcoinmarket.com launched. However, due to lack of liquidity and transaction depth, it disappeared soon after its establishment, but Bitcoinmarket.com opened the era of the operation of the cryptocurrency realm exchange 1.0.


On June 9, 2011, China’s first Bitcoin exchange — Bitcoin China (BTCChina) launched. Its founder, Yang Linke, translated Bitcoin into Chinese “比特币” for the first time. In 2013, China’s bitcoin trading entered the golden age, and exchanges sprung up. China monopolized more than 90% of the world’s bitcoin transactions. Now, if the top three exchanges Binance, Huobi Global, OKEx are the Exchange 2.0, then the index exchange represented by 58COIN called the 3.0 version, leading the trend.
The First Generation of High-Performance Miner — ASIC Miner
When Satoshi Nakamoto created Bitcoin, the only way to get it is to use computers (including home computers) to mine, mainly relying on the CPU to calculate. However, as the value of digital currencies such as Bitcoin has become higher and higher, mining has become an industry with the competition is getting fiercer, accompanied by increasing difficulty of mining. Therefore, hardware performance competition starts.
In July 2012, the genius Jiang Xinyu (Internet nickname is “Friedcat”) from the junior class of the University of Science and Technology declared at the forum that he could make ASIC miners (chips). As far as mining computing power is concerned, ASICs can be tens of thousands or more higher than the same-generation CPUs and GPUs.
At the beginning of 2013, Zhang Nanqian (Pumpkin Zhang), a suspended doctoral student from the Beijing University of Aeronautics and Astronautics, developed the ASIC miner and named it “Avalon”.


In June 2013, the Friedcat’s miner USB was finally released, and it maintained 20% of the computing power of the entire network.
At the end of 2013, Wu Jihan, used the tens of millions yuan earned from Friedcat through investment, worked together with Jenke group, to develop the Antminer S1. Since then, the miner manufacturer Bitmain began to enter the stage of history.
It is no exaggeration to say that Friedcat and Zhang Nangeng have opened the domestic “mining” era.
The Birthplace of China’s Bitcoin — Garage Coffee
It is not only the “old objects” that record history, but also a place that everyone in the cryptocurrency realm aspires to.
Guo Hongcai once said, “Without no The Garage Café, there will be no cryptocurrency realm today. Since it is a very mysterious place that all waves of people from the café joint together to create today’s digital asset industry.

▲ In March 2013, American student Jake Smith successfully purchased a cup of coffee at The Garage Café with 0.131 bitcoins. This move attracted the attention of CCTV, and it conducted an interview.
Indeed, The Garage Café is the world ’s first entrepreneurial-themed coffee shop. It has been legendary since its establishment in 2011. The Garage Cafét is not only the core coordinate on China’s Bitcoin map, but also the birthplace of the Chinese cryptocurrency circle, where digital asset realm tycoons including Guo Hongcai, Zhao Dong, Li Xiaolai, Li Lin have made their ways.
The development of digital currency is only 11 years old. Through these “old objects”, we review the various stories of this wave of technology together, hoping to help you understand the development process of the digital currency field. Meanwhile, I also remind all practitioners to use history as a mirror and forge ahead.

Decred Journal – August 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link) to see all the links.

Development

dcrd: Version 1.3.0 RC1 (Release Candidate 1) is out! The main features of this release are significant performance improvements, including some that benefit SPV clients. Full release notes and downloads are on GitHub.
The default minimum transaction fee rate was reduced from 0.001 to 0.0001 DCkB. Do not try to send such small fee transactions just yet, until the majority of the network upgrades.
Release process was changed to use release branches and bump version on the master branch at the beginning of a release cycle. Discussed in this chat.
The codebase is ready for the new Go 1.11 version. Migration to vgo module system is complete and the 1.4.0 release will be built using modules. The list of versioned modules and a hierarchy diagram are available here.
The testnet was reset and bumped to version 3.
Comments are welcome for the proposal to implement smart fee estimation, which is important for Lightning Network.
@matheusd recorded a code review video for new Decred developers that explains how tickets are selected for voting.
dcrwallet: Version 1.3.0 RC1 features new SPV sync mode, new ticket buyer, new APIs for Decrediton and a host of bug fixes. On the dev side, dcrwallet also migrated to the new module system.
Decrediton: Version 1.3.0 RC1 adds the new SPV sync mode that syncs roughly 5x faster. The feature is off by default while it receives more testing from experienced users. Other notable changes include a design polish and experimental Politeia integration.
Politeia: Proposal editing is being developed and has a short demo. This will allow proposal owners to edit their proposal in response to community feedback before voting begins. The challenges associated with this feature relate to updating censorship tokens and maintaining a clear history of which version comments were made on. @fernandoabolafio produced this architecture diagram which may be of interest to developers.
@degeri joined to perform security testing of Politeia and found several issues.
dcrdata: mainnet explorer upgraded to v2.1 with several new features. For users: credit/debit tx filter on address page, showing miner fees on coinbase transaction page, estimate yearly ticket rewards on main page, cool new hamburger menu and keyboard navigation. For developers: new chain parameters page, experimental Insight API support, endpoints for coin supply and block rewards, testnet3 support. Lots of minor API changes and frontend tweaks, many bug fixes and robustness improvements.
The upcoming v3.0 entered beta and is deployed on beta.dcrdata.org. Check out the new charts page. Feedback and bug reports are appreciated. Finally, the development version v3.1.0-pre is on alpha.dcrdata.org.
Android: updated to be compatible with the latest SPV code and is syncing, several performance issues are worked on. Details were posted in chat. Alpha testing has started, to participate please join #dev and ask for the APK.
iOS: backend is mostly complete, as well as the front end. Support for devices with smaller screens was improved. What works now: creating and recovering wallets, listing of transactions, receiving DCR, displaying and scanning QR codes, browsing account information, SPV connection to peers, downloading headers. Some bugs need fixing before making testable builds.
Ticket splitting: v0.6.0 beta released with improved fee calculation and multiple bug fixes.
docs: introduced new Governance section that grouped some old articles as well as the new Politeia page.
@Richard-Red created a concept repository sandbox with policy documents, to illustrate the kind of policies that could be approved and amended by Politeia proposals.
decred.org: 8 contributors added and 4 removed, including 2 advisors (discussion here).
decredmarketcap.com is a brand new website that shows the most accurate DCR market data. Clean design, mobile friendly, no javascript required.
Dev activity stats for August: 239 active PRs, 219 commits, 25k added and 11k deleted lines spread across 8 repositories. Contributions came from 2-10 developers per repository. (chart)

Network

Hashrate: went from 54 to 76 PH/s, the low was 50 and the new all-time high is 100 PH/s. BeePool share rose to ~50% while F2Pool shrank to 30%, followed by coinmine.pl at 5% and Luxor at 3%.
Staking: 30-day average ticket price is 95.6 DCR (+3.0) as of Sep 3. During the month, ticket price fluctuated between a low of 92.2 and high of 100.5 DCR. Locked DCR represented between 3.8 and 3.9 million or 46.3-46.9% of the supply.
Nodes: there are 217 public listening and 281 normal nodes per dcred.eu. Version distribution: 2% at v1.4.0(pre) (dev builds), 5% on v1.3.0 (RC1), 62% on v1.2.0 (-5%), 22% on v1.1.2 (-2%), 6% on v1.1.0 (-1%). Almost 69% of nodes are v.1.2.0 and higher and support client filters. Data snapshot of Aug 31.

ASICs

Obelisk posted 3 email updates in August. DCR1 units are reportedly shipping with 1 TH/s hashrate and will be upgraded with firmware to 1.5 TH/s. Batch 1 customers will receive compensation for missed shipment dates, but only after Batch 5 ships. Batch 2-5 customers will be receiving the updated slim design.
Innosilicon announced the new D9+ DecredMaster: 2.8 TH/s at 1,230 W priced $1,499. Specified shipping date was Aug 10-15.
FFMiner DS19 claims 3.1 TH/s for Blake256R14 at 680 W and simultaneously 1.55 TH/s for Blake2B at 410 W, the price is $1,299. Shipping Aug 20-25.
Another newly noticed miner offer is this unit that does 46 TH/s at 2,150 W at the price of $4,720. It is shipping Nov 2018 and the stats look very close to Pangolin Whatsminer DCR (which has now a page on asicminervalue).

Integrations

www.d1pool.com joined the list of stakepools for a total of 16.
Australian CoinTree added DCR trading. The platform supports fiat, there are some limitations during the upgrade to a new system but also no fees in the "Early access mode". On a related note, CoinTree is working on a feature to pay household bills with cryptocurrencies it supports.
Three new OTC desks were added to exchanges page at decred.org.
Two mobile wallets integrated Decred:
Reminder: do your best to understand the security and privacy model before using any wallet software. Points to consider: who controls the seed, does the wallet talk to the nodes directly or via middlemen, is it open source or not?

Markets

DCR started the month at USD 56 / BTC 0.0073 and had a two week decline. On Aug 14 the whole market took a huge drop and briefly went below USD 200 billion. Bitcoin went below USD 6,000 and top 100 cryptos lost 5-30%. The lowest point coincided with Bitcoin dominance peak at 54.5%. On that day Decred dived -17% and reached the bottom of USD 32 / BTC 0.00537. Since then it went sideways in the USD 35-45 / BTC 0.0054-0.0064 range. Around Aug 24, Huobi showed DCR trading volume above USD 5M and this coincided with a minor recovery.
@ImacallyouJawdy posted some creative analysis based on ticket data.

Relevant External

StopAndDecrypt published an extensive article "ASIC Resistance is Nothing but a Blockchain Buzzword" that is much in line with Decred's stance on ASICs.
The ongoing debates about the possible Sia fork yet again demonstrate the importance of a robust dispute resolution mechanism. Also, we are lucky to have the treasury.
Mark B Lundeberg, who found a vulnerability in atomicswap earlier, published a concept of more private peer-to-peer atomic swaps. (missed in July issue)
Medium took a cautious stance on cryptocurrencies and triggered at least one project to migrate to Ghost (that same project previously migrated away from Slack).
Regulation: Vietnam bans mining equipment imports, China halts crypto events and tightens control of crypto chat groups.
Reddit was hacked by intercepting 2FA codes sent via SMS. The announcement explains the impact. Yet another data breach suggests to think twice before sharing any data with any company and shift to more secure authentication systems.
Intel and x86 dumpsterfire keeps burning brighter. Seek more secure hardware and operating systems for your coins.
Finally, unrelated to Decred but good for a laugh: yetanotherico.com.

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

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.

AMA with Wanchain VP Lini

AMA with Wanchain VP Lini
Original article here: https://medium.com/wanchain-foundation/ama-with-wanchain-vp-lini-58ada078b4fe

“What is unique about us is that we have actually put theory into practice.”
— Lini
https://preview.redd.it/n6lo2xcmtn621.png?width=800&format=png&auto=webp&s=281acce4b45eed8acf0c52b201d01cb6f0d13507
https://preview.redd.it/10aj3ointn621.png?width=800&format=png&auto=webp&s=6a187e8a6eb5ac0445ddc73d5b0f9077f12bce39
Wanchain’s Vice President of Business Development, Lini, sat down with blockchain media organization Neutrino for an AMA covering a wide range of topics concerning Wanchain’s development.
The following is an English translation of the original Chinese AMA which was held on December 13th, 2018:
Neutrino: Could you please first share with us a little basic background, what are the basic concepts behind cross chain technology? What are the core problems which are solved with cross-chain? In your opinion, what is the biggest challenge of implementing cross chain to achieve value transfer between different chains?
Lini: Actually, this question is quite big. Let me break it down into three smaller parts:
  1. First, what is the meaning of “cross-chain”?
https://preview.redd.it/cpui6t7qtn621.png?width=720&format=png&auto=webp&s=86bc39d94b0713949c150598e2397a4f9d3ac491
In China, we like to use the word “cross-chain”, the term “interoperability” is used more frequently in foreign countries. Interoperability is also one of the important technologies identified by Vitalik for the development of a future blockchain ecosystem mentioned in the Ethereum white paper. So cross-chain is basically the concept of interoperability between chains.
  1. The core problem solved by cross chain is that of “multi-ledger” synchronous accounting
https://preview.redd.it/603dl86stn621.png?width=720&format=png&auto=webp&s=425b827298ac919f8cf05909037458a173100cc4
In essence, blockchain is a distributed bookkeeping technique, also known as distributed ledger technology. Tokens are the core units of account on each chain, there currently exist many different chains, each with their own token. Of especial importance is the way in which each ledger uses tokens to interact with each other for the purpose of clearing settlements.
  1. The core purpose of the cross-chain technology is as one of the key infrastructures of the future economy based on digital currencies.
https://preview.redd.it/3d61f26utn621.png?width=720&format=png&auto=webp&s=b735482c9734e1d32176e406adce1718be20583e
Cross chain technology is one of the foundational technological infrastructures that is necessary for the large scale application of blockchain technology.
Neutrino: As we all know, there are many different kinds of cross-chain technologies. Please give us a brief introduction to several popular cross-chain technologies on the market, and the characteristics of each of these technologies。
Lini: Before answering this question, it is very important to share two important concepts with our friends: heterogeneity and homogeneity, and centralization and decentralization.
https://preview.redd.it/n6wbs77wtn621.png?width=720&format=png&auto=webp&s=83fcadd09afb214d2aa5a2a6deb6c24d0d4da671
These two points are especially important for understanding various cross-chain technologies, because there are many different technologies and terminologies, and these are some of the foundational concepts needed for understanding them.
There are also two core challenges which must be overcome to implement cross-chain:
https://preview.redd.it/84wqd28ytn621.png?width=720&format=png&auto=webp&s=dafe1cd2993f853547b532421404e6ab86e185f1
Combining the above two points, we look at the exploration of some solutions in the industry and the design concepts of other cross-chain projects.
First I’d like to discuss the Relay solution.
https://preview.redd.it/qgcqiwlztn621.png?width=720&format=png&auto=webp&s=0925d4221c9e92e365e150638c645bef8c609b3f
However the Relay solution must consume a relatively large amount of gas to read the BTC header. Another downside is that, as we all know, Bitcoin’s blocks are relatively slow, so the time to wait for verification will be long, it usually takes about 10 minutes to wait for one block to confirm, and the best practice is to wait for 6 blocks.
The next concept is the idea of Sidechains.
https://preview.redd.it/9cg79bl1un621.png?width=720&format=png&auto=webp&s=1260e14213b1757eadc4b6141a365ed3b0e20316
This solution is good, but not all chains contain SPV, a simple verification method. Therefore, there are certain drawbacks. Of course, this two way peg way solves challenge beta very well, that is, the atomicity of the transaction.
These two technical concepts have already been incorporated into a number of existing cross chain projects. Let’s take a look at two of the most influential of these.
The first is Polkadot.
https://preview.redd.it/1o3xwz93un621.png?width=720&format=png&auto=webp&s=249909a33b5420050a6010b961a944285fc94926
This is just a summary based on Polkadot’s whitepaper and most recent developments. The theoretical design is very good and can solve challenges alpha and beta. Last week, Neutrino organized a meetup with Polkadot, which we attended. In his talk, Gavin’s focus was on governance, he didn’t get into too much technical detail, but Gavin shared some very interesting ideas about chain governance mechanisms! The specific technical details of Polkadot may have to wait until after their main net is online before it can be analyzed.
Next is Cosmos.
https://preview.redd.it/5gtjf6x4un621.png?width=720&format=png&auto=webp&s=94d6408ff65dc7041316f0130867888e108848b2
Cosmos is a star project who’s basic concept is similar to Polkadot. Cosmos’s approach is based on using a central hub. Both projects both take into account the issue of heterogeneous cross-chain transactions, and both have also taken into account how to solve challenges alpha and beta.
To sum up, each research and project team has done a lot of exploration on the best methods for implementing cross-chain technology, but many are still in the theoretical design stage. Unfortunately, since the main net has not launched yet, it is not possible to have a more detailed understanding of each project’s implementation. A blockchain’s development can be divided into two parts: theoretical design, and engineering implementation. Therefore, we can only wait until after the launch of each project’s main network, and then analyze it in more detail.
Neutrino: As mentioned in the white paper, Wanchain is a general ledger based on Ethereum, with the goal of building a distributed digital asset financial infrastructure. There are a few questions related to this. How do you solve Ethereum’s scaling problem? How does it compare with Ripple, which is aiming to be the standard trading protocol that is common to all major banks around the world? As a basic potential fundamental financial infrastructure, what makes Wanchain stand out?
Lini: This question is actually composed of two small questions. Let me answer the first one first.
  1. Considerations about TPS.
First of all, Wanchain is not developed on Ethereum. Instead, it draws on some of Ethereum’s code and excellent smart contracts and virtual machine EVM and other mature technical solutions to build the mainnet of Wanchain.
The TPS of Ethereum is not high at this stage, which is limited by various factors such as the POW consensus mechanism. However, this point also in part is due to the characteristics of Ethereum’s very distributed and decentralized features. Therefore, in order to improve TPS, Wanchain stated in its whitepaper that it will launch its own POS consensus, thus partially solving the performance issues related to TPS. Wanchain’s POS is completely different from the POS mechanism of Ethereum 2.0 Casper.
Of course, at the same time, we are also paying close attention to many good proposals from the Ethereum community, such as sharding, state channels, side chains, and the Raiden network. Since blockchain exists in the world of open source, we can of course learn from other technological breakthroughs and use our own POS to further improve TPS. If we have some time at the end, I’d love to share some points about Wanchain’s POS mechanism.
  1. Concerning, Ripple, it is completely different from what Wanchain hopes to do.
Ripple is focused on exchanges between different fiat pairs, the sharing of data between banks and financial institutions, as a clearing and settlement system, and also for the application of DLT, for example the Notary agent mechanism.
Wanchain is focused on different use cases, it is to act as a bridge between different tokens and tokens, and between assets and tokens. For various cross-chain applications it is necessary to consume WAN as a gas fee to pay out to nodes.
So it seems that the purpose Ripple and Wanchain serve are quite different. Of course, there are notary witnesses in the cross-chain mechanism, that is, everyone must trust the middleman. Ripple mainly serves financial clients, banks, so essentially everyone’s trust is already there.
Neutrino: We see that Wanchain uses a multi-party computing and threshold key sharing scheme for joint anchoring, and achieves “minimum cost” for integration through cross-chain communication protocols without changing the original chain mechanism. What are the technical characteristics of multi-party computing and threshold key sharing? How do other chains access Wanchain, what is the cross-chain communication protocol here? What is the cost of “minimum cost?
Lini: The answer to this question is more technical, involving a lot of cryptography, I will try to explain it in a simple way.
  1. About sMPC -
It stands for secure multi-party computation. I will explain it using an example proposed by the scholar Andrew Yao, the only Turing Award winner in China. The scenario called Yao’s Millionaire Problem. How can two millionaires know who is wealthier without revealing the details of their wealth to each other or a trusted third party? I’m not going to explain the answer in detail here, but those who are interested can do a web search to learn more.
In sMPC multiple parties each holding their own piece of private data jointly perform a calculation (for example, calculating a maximum value) and obtain a calculation result. However, in the process, each party involved does not leak any of their respective data. Essentially sMPC calculation can allow for designing a protocol without relying on any trusted third parties, since no individual ever has access to the complete private information.
Secure multiparty computing can be abstractly understood as two parties who each have their own private data, and can calculate the results of a public function without leaking their private data. When the entire calculation is completed, only the calculation results are revealed to both parties, and neither of them knows the data of the other party and the intermediate data of the calculation process. The protocol used for secure multiparty computing is homomorphic encryption + secret sharing + OT (+ commitment scheme + zero knowledge proofs, etc.)
Wanchain’s 21 cross chain Storeman nodes use sMPC to participate in the verification of a transaction without obtaining of a user’s complete private key. Simply put, the user’s private key will have 21 pieces given to 21 anonymous people who each can only get 1/21 part, and can’t complete the whole key.
  1. Shamir’s secret sharing
There are often plots in a movie where a top secret document needs to be handed over to, let’s say five secret agents. In order to protect against the chance of an agent from being arrested or betraying the rest, the five agents each hold only part of a secret key which will reveal the contents of the documents. But there is also a hidden danger: if one the agents are really caught, how can the rest of the agents access the information in the documents? At this point, you may wonder if there is any way for the agents to still recover the original text with only a portion of the keys? In other words, is there any method that allows a majority of the five people to be present to unlock the top secret documents? In this case, the enemy must be able to manipulate more than half of the agents to know the information in the secret documents.
Wanchain uses the threshold M<=N; N=21; M=16. That is to say, at least 16 Storeman nodes must participate in multi-party calculation to confirm a transaction. Not all 21 Storeman nodes are required to participate. This is a solution to the security problem of managing private keys.
Cross-chain communication protocols refers to the different communication methods used by different chains. This is because heterogeneous cross-chain methods can’t change the mechanism of the original chains. Nakamoto and Vitalik will not modify their main chains because they need BTC and ETH interoperability. Therefore, project teams that can only do cross-chain agreements to create different protocols for each chain to “talk”, or communicate. So the essence of a cross-chain protocol is not a single standard, but a multiple sets of standards. But there is still a shared sMPC and threshold design with the Storeman nodes.
The minimum cost is quite low, as can be shown with Wanchain 3.0’s cross chain implementation. In fact it requires just two smart contracts, one each on Ethereum and Wanchain to connect the two chains. To connect with Bitcoin all that is needed is to write a Bitcoin script. Our implementation guarantees both security and decentralization, while at the same time remaining simple and consuming less computation. The specific Ethereum contract and Bitcoin scripts online can be checked out by anyone interested in learning more.
Neutrino: What kind of consensus mechanism is currently used by Wanchain? In addition, what is the consensus and incentive mechanism for cross-chain transactions, and what is the purpose of doing so? And Wanchain will support cross-chain transactions (such as BTC, ETH) on mainstream public chains, asset cross-chain transactions between the alliance chains, and cross-chain transactions between the public and alliance chains, how can you achieve asset cross-chain security and privacy?
Lini: It is now PPOW (Permissioned Proof of Work), in order to ensure the reliability of the nodes before the cross-chain protocol design is completed, and to prepare to switch to POS (as according to the Whitepaper roadmap). The cross-chain consensus has been mentioned above, with the participation of a small consensus (at least 16 nodes) in a set of 21 Storeman nodes through sMPC and threshold secret sharing.
In addition, the incentive is achieved through two aspects: 1) 100% of the cross chain transaction fee is used to reward the Storeman node; 2) Wanchain has set aside a portion of their total token reserve as an incentive mechanism for encouraging Storeman nodes in case of small cross-chain transaction volume in the beginning.
It can be revealed that Storeman participation is opening gradually and will become completely distributed and decentralized in batches. The first phase of the Storeman node participation and rewards program is to be launched at the end of 2018. It is expected that the selection of participants will be completed within one quarter. Please pay attention to our official announcements this month.
In addition, for public chains, consortium chains, and private chains, asset transfer will also follow the cross-chain mechanism mentioned above, and generally follow the sMPC and threshold integration technology to ensure cross-chain security.
When it comes to privacy, this topic will be bigger. Going back to the Wanchain Whitepaper, we have provided privacy protection on Wanchain mainnet. Simply put, the principle is using ring signatures. The basic idea is that it mixes the original address with many other addresses to ensure privacy. We also use one-time address. In this mechanism a stamp system is used that generates a one-time address from a common address. This has been implemented since our 2.0 release.
But now only the privacy protection of native WAN transactions can be provided. The protection of cross-chain privacy and user experience will also be one of the important tasks for us in 2019.
Neutrino: At present, Wanchain uses Storeman as a cross-chain trading node. Can you introduce the Storeman mechanism and how to protect these nodes?
Lini: Let me one problem from two aspects.
  1. As I introduced before in my explanation of sMPC, the Storeman node never holds the user’s private key, but only calculates the transaction in an anonymous and secure state, and the technology prevents the Storeman nodes from colluding.
  2. Even after technical guarantees, we also designed a “double protection” against the risk from an economic point of view, that is, each node participating as a Storeman needs to pledge WAN in the contract as a “stake”. The pledge of WAN will be greater than the amount of any single transaction as a guarantee against loss of funds.
If the node is malicious (even if it is a probability of one in a billion), the community will be compensated for the loss caused by the malicious node by confiscation of the staked WAN. This is like the POS mechanism used by ETH, using staking to prevent bad behavior is a common principle.
Neutrino: On December 12th, the mainnet of Wanchain 3.0 was launched. Wanchain 3.0 opened cross-chain transactions between Bitcoin, Ethereum and ERC20 (such as MakerDao’s stable currency DAI and MKR). What does this version mean for you and the industry? This upgrade of cross-chain with Bitcoin is the biggest bright spot. So, if now you are able to use Wanchain to make transactions between what is the difference between tokens, then what is the difference between a cross chain platform like Wanchain and cryptocurrency exchanges?
Lini: The release of 3.0 is the industry’s first major network which has crossed ETH and BTC, and it has been very stable so far. As mentioned above, many cross-chain, password-protected theoretical designs are very distinctive, but for engineering implementation, the whether or not it can can be achieved is a big question mark. Therefore, this time Wanchain is the first network launched in the world to achieve this. Users are welcome to test and attack. This also means that Wanchain has connected the two most difficult and most challenging public networks. We are confident we will soon be connecting other well-known public chains.
At the same time of the release of 3.0, we also introduced cross chain integration with other ERC20 tokens in the 2.X version, such as MakerDao’s DAI, MKR, LRC, etc., which also means that more tokens of excellent projects on Ethereum will also gradually be integrated with Wanchain.
Some people will be curious, since Wanchain has crossed so many well-known public chains/projects; how is it different with crypto exchanges? In fact, it is very simple, one centralized; one distributed. Back to the white paper of Nakamoto, is not decentralization the original intention of blockchain? So what Wanchain has to do is essentially to solve the bottom layer of the blockchain, one of the core technical difficulties.
Anyone trying to create a DEX (decentralized exchange); digital lending and other application scenarios can base their application on Wanchain. There is a Wanchain based DEX prototype made by our community members Jeremiah and Harry, which quite amazing. Take a look at this video below.
https://www.youtube.com/watch?v=codcqb66G6Q
Neutrino: What are the specific application use cases after the launch of Wanchain 3.0? Most are still exploring small-scale projects. According to your experience, what are the killer blockchain applications of the future? What problems need to be solved during this period? How many years does it take?
Lini:
  1. Wanchain is just a technology platform rather than positioning itself as an application provider; that is, Wanchain will continue to support the community, and the projects which use cross-chain technology to promote a wide range of use cases for Wanchain.
  2. Cross-chain applications that we anticipate include things like: decentralized exchanges, digital lending, cross chain games, social networking dAPPs, gambling, etc. We also expect to see applications using non fungible tokens, for example exchange of real assets, STOs, etc.
  3. We recently proposed the WanDAPP solution. Simply speaking, a game developer for example has been developing on Ethereum, and ERC20 tokens have been issued, but they hope to expand the player base of their games to attract more people. To participate and make full use of their DAPP, you can consider using the WanDAPP solution to deploy the game DAPP on other common platforms, such as EOS, TRON, etc., but you don’t have to issue new tokens on these chains or use the previous ERC20 tokens. In this way the potential user population of the game can be increased greatly without issuing more tokens on a new chain, improving the real value of the original token. This is accomplished completely using the cross-chain mechanism of Wanchain.
  4. For large-scale applications, the infrastructure of the blockchain is not yet complete, there are issues which must first be dealt with such as TPS, sharding, sidechains, state channels, etc. These all must be solved for the large-scale application of blockchain applications. I don’t dare to guess when it will be completed, it depends on the progress of various different technical projects. In short, industry practitioners and enthusiasts need a little faith and patience.
Neutrino community member Block Venture Capital Spring: Will Wanchain be developing any more cross chain products aimed at general users? For example will the wallet be developed to make automatic cross chain transfers with other public chains? Another issue the community is concerned about is the currency issuance. Currently there are more than 100 million WAN circulating, what about the rest, when will it be released?
Lini: As a cross-chain public chain, we are not biased towards professional developers or ordinary developers, and they are all the same. As mentioned above, we provide a platform as infrastructure, and everyone is free to develop applications on us.
For example, if it is a decentralized exchange, it must be for ordinary users to trade on; if it is some kind of financial derivatives product, it is more likely to be used by finance professionals. As for cross-chain wallets which automatically exchange, I’m not sure if you are talking about distributed exchanges, the wallet will not be “automatic” at first, but you can “automatically” redeem other tokens.
Finally, the remaining WAN tokens are strictly in accordance with the plan laid out in the whitepaper. For example, the POS node reward mentioned above will give 10% of the total amount for reward. At the same time, for the community, there are also rewards for the bounty program. The prototype of the DEX that I just saw is a masterpiece of the overseas community developers, and also received tokens from our incentive program.
Neutrino community member’s question: There are many projects in the market to solve cross-chain problems, such as: Cosmos, Polkadot, what are Wanchain’s advantages and innovations relative to these projects?
Lini: As I mentioned earlier, Cosmos and pPolkadot all proposed very good solutions in theory. Compared with Wanchain, I don’t think that we have created anything particularly unique in our theory. The theoretical basis for our work is cryptography, which is derived from the academic foundation of scholars such as Yao Zhizhi and Silvio Micali. Our main strong point is that we have taken theory and put it into practice..
Actually, the reason why people often question whether a blockchain project can be realized or not is because the whitepapers are often too ambitious. Then when they actually start developing there are constant delays and setbacks. So for us, we focus on completing our very solid and realizable engineering goals. As for other projects, we hope to continue to learn from each other in this space.
Neutrino community member Amos from Huobi Research Institute question: How did you come to decide on 21 storeman nodes?
Lini: As for the nodes we won’t make choices based on quantity alone. The S in the POS actually also includes the time the tokens are staked, so that even if a user is staking less tokens, the amount of time they stake them for will also be used to calculate the award, so that is more fair. We designed the ULS (Unique Leader Selection) algorithm in order to reduce the reliance on the assumption of corruption delay (Cardano’s POS theory). which is used for ensuring fairness to ensure that all participants in the system can have a share of the reward, not only few large token holders.
Wu Di, a member of the Neutrino community: Many big exchanges have already begun to deploy decentralized exchanges. For example, Binance, and it seems that the progress is very fast. Will we be working with these influential exchanges in the future? We we have the opportunity to cooperate with them and broaden our own influence?
Lini: I also have seen some other exchange’s DEX. Going back the original point, distributed cross-chain nodes and centralized ones are completely different. I’m guessing that most exchanges use a centralized cross-chain solution, so it may not be the same as the 21 member Storeman group of Wanchain, but I think that most exchanges will likely be using their own token and exchange system. This is my personal understanding. But then, if you are developing cross chain technology, you will cooperate with many exchanges that want to do a DEX. Not only Binance, but also Huobi, Bithumb, Coinbase… And if there is anyone else who would like to cooperate we welcome them!
Neutrino community member AnneJiang from Maker: Dai as the first stable chain of Wanchain will open a direct trading channel between Dai and BTC. In relation to the Dai integration, has any new progress has been made on Wanchain so far?
Lini: DAI’s stable currency has already been integrated on Wanchain. I just saw it yesterday, let me give you a picture. It’s on the current 3.0 browser, https://www.wanscan.org/, you can take a look at it yourself.
This means that users with DAI are now free to trade for BTC, or ETH or some erc20 tokens. There is also a link to the Chainlink, and LRC is Loopring, so basically there are quite a few excellent project tokens. You may use the Wanchain to trade yourself, but since the DEX is not currently open, currently you can only trade with friends you know.

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.

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.

Atomic Swap with USDT: Swap Online solution in two hundred lines of code

Atomic Swap with USDT: Swap Online solution in two hundred lines of code
https://preview.redd.it/3mx7amtio9g11.png?width=696&format=png&auto=webp&s=f2bd956843196fa2f51048a86f9608b6e714f62e
On the eve of the release on the mainnet, the team of the cross-chain wallet Swap Online is publishing a research study and the code of the atomic swapusing USDT.

USD Tether — the equivalent of the dollar on Omni Layer

The solution described above with the protocol “over” the Bitcoin network gave life to one of the most controversial cryptocurrency projects of the last two years — Tether. Tether (symbol Tether — ₮, ticker — USDT) is a hybrid cryptocurrency with a rate binding to one US dollar. Moreover, according to the assurances of Tether Limited, the issuer of the given tokens, the “binding” is to be understood literally, as each purchased token of USDT corresponds to one US dollar available at the disposal of the company.
If we take the three largest exchanges based on their daily turnover of transactions at the time of writing (Binance, OKEx and HuObi), and then track the five most popular trading pairs for each, we will encounter USDT in 13 out of 15 cases.

USDT — the token with the largest capitalization in the world.

All this generates great community interest in faster, safer and cheaper solutions for exchanging Tether into other currencies. Obviously, such a solution could be atomic swaps, which are instant, decentralized cross-chain exchanges. The Komodo laboratory, the main headliners of this technology, who presented it in the autumn of 2017, reported on the successful exchange of KMD to USDT carried out on the BarterDEX platform, Komodo’s own exchanger.

At the same time, according to our data, the developers of Komodo made a swap on the ERC20-a version of Tether, which is only available in 3% of cases. Approximately 60 million USDT from global turnover can thus be exchanged using this method, which, obviously, cannot be considered as a solution to the problem. Striking examples of imperfections of existing solutions can be found even on Etherscan.

This fall, the team of Swap Online is ready to present an atomic swap with Tether. And here’s how we did it.

How Omni conducts transactions

To carry out the Omni transaction, a user needs to create a regular Bitcoin transaction-transfer of 546 satoshi (minimum) with an additional output storing payload using the OP_RETURN op-code. An example of such a transaction. The payload is a mandatory part of any Omni transaction, as it is a sequence of bytes containing all the necessary information about the transaction.

Let us consider what information is stored in the payload itself

transaction marker — 4 bytes, the mandatory part of any Omni payload is always equal to 0x6f6d6e69 — ASCII code omni. If the first 4 bytes of the sequence are not equal to 0x6f6d6e69, then this sequence is not a payload of Omni.
version — 2 bytes, an analog version of the transaction in Bitcoin. For the described algorithm to work, version 0 is used, or that is the same as 0x0000.
transaction type — 2 bytes, transaction type, for an atomic swap it is sufficient to use only “Simple send” transactions, as simple send is the usual sending of omni currency from its address to the address of the recipient. Simple send corresponds to the transaction type code 0, that is, the next 2 bytes 0x0000. Other possible types of transactions exist in Omni.
token identifier — 4 bytes, identifier of the currency used. For example TetherUS has the identifier 31 or 0x0000001f. All tokens created by the Omni protocol at this time can be seen via the following link.
amount — 8 bytes, for a transaction of type Simple send, this is the amount of the sent currency.
As you can see, payload does not store the addresses of senders and recipients of the transactions, these addresses are determined by the Bitcoin transaction in which the payload output was detected. By scanning inputs, the Omni protocol determines who makes the transfer by finding the output of the corresponding address from among the inputs of the transaction p2pkh.
Thus, for a transfer from Alice to Bob of, for example, 50,000,000 TetherUS, we need to create a Bitcoin transaction where one of the inputs will refer to the p2pkh output corresponding to the Alice address. It is also important that this entry be the first in this transaction (the index of this entry in the received transaction would be is minimal or none at all). One of the outputs of this transaction should be the output of p2pkh to Bob’s address, and another output must have been one of the outputs with the following payload:
https://preview.redd.it/0kmuzds8p9g11.png?width=575&format=png&auto=webp&s=af2f496596684af18091fb044f4e20b7e546c32f
Example 1
Example 2

Atomic Swap on Omni Layer

Suppose that Alice and Bob are willing to make an inter-blockchain exchange of cryptocurrencies. Alice wants to exchange the units of any Omni currency, for example TetherUS (the given currency has the currency identifier # 31 in the Mainnet, then in the text we will only talk about this currency of the Omni protocol, since it is the most popular at the moment, but the algorithm below will work for any currency of the Omni protocol as well) for b units of a cryptocurrency working on another blockchain. (Omni works on top of the Bitcoin blockchain, of course, according to the algorithm below it is possible to exchange TetherUS for Bitcoins, but due to their work on one and the same blockchain, this exchange can be done in a different, more efficient way).

Glossary

A — blockchain of Bitcoin.
B — the blockchain of the cryptocurrency for which TetherUS is being exchanged.
a — the sum of TetherUS, which Alice wants to exchange.
b — the sum of the cryptocurrency of the adjoining blockchain B, to which Alice wants to exchange her a TetherUS.

Creating a Transaction

1) Bob generates a random value secret.
2) Bob calculates the secretHash by performing the following operation: secretHash = RIPEMD160 (secret)
3) Bob creates and sends an htlc transaction sealed by secretHash
4) Bob sends Alice a secretHash value, and a hash of the hrlc transaction he created in the previous paragraph in order for Alice to make sure that the correct htlc transaction is actually present in the B blockchain.
5) Alice received from Bob the secretHash and hash of the htlc-transaction Bob created, and is convinced that such a transaction is really present in the B blockchain, and that this is indeed a htlc-transaction sealed by the secretHash value.
6) using the received secretHash, Alice creates the following transaction and translates it into the Bitcoin blockchain:
https://preview.redd.it/oxri5a7gp9g11.png?width=735&format=png&auto=webp&s=14e88db4fc4d1743406939343d42e33352b05782
Let us call such a transaction financing_tx. In fact, it is almost an ordinary Bitcoin htlc transaction that is used in atomic swap with the only difference that in the amount field, 546 satoshi is the minimum number of Bitcoins that can be at the output of the transaction, below this value, Bitcoin counts the transaction as dust and does not conduct it.
7) Alice creates a transaction according to the following scheme:
https://preview.redd.it/awz9uzuhp9g11.png?width=1000&format=png&auto=webp&s=9ca79e77ca6aff631a39ae95dfaa70aa06d695ec
Let us call this transaction redeem_tx. Alice creates such a transaction with two inputs: the first is the input referencing the output of funding_tx, which contains the htlc script. Alice does not sign this script, that is, the SigScript field remains completely empty. The second input is the input referring to any unspent exits of Alice, the main condition is that at this output stage there are enough Bitcoins to pay the transaction fee, and this entry is signed by Alice with her private key with the signature type SIGHASH_ALL (that is, she signs the entire transaction except for SigScript fields on the inputs transaction, which makes this transaction immutable. The outputs of the same transaction are the elementary Simple Send and a TetherUS from Alice to Bob (details of what Simple Send, payload is and how it works can be found in another section).
8) Alice sends Bob the redeem_tx created in the previous paragraph and the one she signed herself.
9) Bob got the redeem_tx sent by Alice, checks it, just looks through the inputs and outputs, making sure that this is really a transaction that Alice should have created using the real algorithm. After that, Bob signs the transaction with his private key and provides the secret value in the SigScript of the corresponding redeem_tx entry.
10) Bob sends the signed redeem_tx transaction to the blockchain, thereby transferring the TetherUS currency from Alice to himself. Note — before carrying out this step, we still need to check that Alice’s address has the necessary amount of TetherUS.
11) Alice looks through blockchain A and gets the value secret and uses it in the B blockchain to transfer the funds using the htlc transaction Bob created in point 3. The exchange ends here.
Stating the obvious: naturally the timelock value used by Bob when creating the htlc-transaction must be significantly longer than the timelock that Alice uses, since her htlc transaction should be spent earlier than the htlc created by Bob. This is necessary so that Bob cannot manage to spend both htlc.

Conclusion

Thus, connecting Omni Layer to Swap Online allows users to cover transactions.
