How GXS Built the Blockcity: Own and Secure Data with 1.8 million Others

Published

on

“Blockcity is the largest and most active blockchain community in China, and even in the whole world,” says Yunpeng Ding, GXChain Regional Manager North America. “We are really proud of the ecosystem we created. As of July 2018, there are more than 1.86 million registered users in Blockcity, comparing to the population of the whole crypto world, this is a really huge proportion. Not to mention 40 percent of them are daily active users.”

Blockcity is a mobile app that incentivizes users to cultivate marketable data and rewards them with GXS tokens if users share their information tags with the community. It aims to create an easy and convenient way for ordinary people to take advantage of the blockchain’s technical advances.

The Blockcity becomes one of the most active blockchain communities not only because its easy access is based on a reliable and stable public chain, GXChain, but also because it offers an effective solution for people to take full control of their personal data.

This July, the research institute of the Ministry of Industry and Information of China has just released its most recent Global Public Blockchain Technology Assessment Index ranking. First time to be included in the index, GXChain is placed fourth out of 31 public chains scoring high on the three factors that the index is based: technology, applications, and innovation.

“Blockcity” is the first personal mobile app developed on the public trust chain – GXChain. It is a personal data management tool that addresses data management and data sharing issues. Its vision is to create a virtual city of blockchain and a microcosm of a future credit society.

Entering Blockcity, users will create a universal digital identity G-ID. This requires users to provide governmental issued identification documents. In this way, Blockcity is linking online and offline credibility, while at the same time keeping all users’ information securely stored.

The users’ operations and behaviors in Blockcity are attentively recorded by the system because the development team of Blockcity believes credibility is the cornerstone of the survival of the whole ecosystem. Moreover, that is why Blockcity becomes an ideal ecosystem for all credit compliance that all social behaviors will be linked to credit and the quality of credit will determine the social status of residents.

Blockcity has a built-in incentive mechanism to encourage users to authorize personal data in multiple dimensions and enrich their data dimensions meaning the users can truly take control of their personal data. Moreover, Blockcity guarantees never to cache data but to protect user privacy. With the user’s authorization, these data can be cultivated and applied to different applications.

GXChain created the CBD data economic ecology on the GXChain. Beside the large personal application on the C terminal – the “Blockcity” Dapp, which is dedicated to solving personal data management and data sharing problems, GXChain also created the first enterprise application on the B terminal – “GXChain Decentralized Exchange”. It uses the decentralized method to address the trust and circulation issues in the data security exchange industry. By providing service and opportunities for developers on the D terminal, GXChain releases the commercial value of those data and creates a better supporting system for the traffic, capital, technology, and platform docking on GXChain.

1. Circulation Exchange
Binance, Gate.io, etc.

2. Stability of Market Value
Despite the bear market in 2018, GXS ranks top 7th in drop resistant among the small market capitalization (50-100) and ranks 28th among top 100 cryptocurrencies.

Up until now, the number of projects applied on GXChain has exceeded 3,000. Nearly 100 projects are under incubation. More than 20 representative projects launched, such as Blockcity, DES, CoinGet, Prophet, Unitopia, WanLiMa, YuBiBao, LendChain, Lucia, DAMO, etc.

The reason why so many people choose GXChain is based on its eight key characteristics:

  • High performance and scalability

GXChain is a public chain with the high concurrent processing capability of up to 100,000 transactions per second. Considering the possibility of conducting business in the chain in the future, the GXChain supports horizontal expansion, which can quickly increase transactions per second without requiring bifurcation to reach consensus.

  • Dynamic adjustment of parameter

GXChain can modify the system parameters without bifurcation and realize the dynamic adjustment of global parameters such as block size, block speed and handling fee through consensus voting. For example, at this moment, one block is output every 3 seconds, and the parameters can be dynamically adjusted to produce one block every second; the current block size is 2M, which can be dynamically adjusted into large blocks, such as 8M.

  • DES data exchange service

Decentralized data exchanges developed on GXChain support data transactions and exchanges in many applications. Corporate and individual developers can access and use the data through transactions.

  • BaaS sidechain storage service

GXChain also provides sufficient support for the BaaS (Blockchain as a Service) interface, such as storage and verification. Developers can develop meaningful Blockchain application in value and significance in real world based on abundant BaaS-API, data transaction API and native API.

  • Massive traffic resources

At present, several million users have registered by real name on GXChain and start developing applications. GXChain allows users to register applications with G-ID one-click, eliminating the complicated registration process so that it can help GXChain reduce the cost of obtaining customers.

  • VM smart contract virtual machine

It provides a programmable and calculable operating environment, allowing the smart contracts for developer projects unimpeded on GXChain.

  • Digital asset issuance

There are digital asset issuance standards on GXChain that allow developers to freely issue, distribute and circulate applications.

  • Code open source

GXChain and related code are a fully open source on Github.

 

Boilerplate:

GXChain

GXChain is a public chain for massive data exchange and application development. It is used to establish a trustworthy domain-wide data exchange value network based on blockchain technology. GXChain has the performance advantages of the Graphene underlying architecture based on the DPoS consensus mechanism and, meanwhile, offers the supporting functions of G-ID, GVM, BaaS, and other chains to facilitate various application development. Based on GXChain, the Dapp “Blockcity” already has over a 1.86 million real-name users, providing rich data resources for chain applications and partners. The GXChain Data Exchange for enterprise services has also been launched and has been serving over 100 companies. GXChain realizes the safety, credibility, freedom, and efficiency of data exchange transaction through the blockchain technology, which provides support for the greater use of data application value.

Stratis Announces New Blockchain Identity App

Published

on

The London-based blockchain company Stratis announced on Thursday that its Stratis Identity mobile application is available to download for iOS devices.

According to the announcement, the free Stratis app allows users to manage their identity and imprint it upon the Stratis blockchain, allowing for secure and verifiable sharing experiences without compromising sensitive personal data. Stratis Identity will also open up the potential for enterprises to securely manage customer identities using cloud-based or internet login services, Stratis stated.

Stratis is a modular platform designed to make blockchain easy, providing simple and affordable end-to-end solutions for development, testing and deployment of native C# blockchain applications (dApps) on the .Net framework.

“Mass adoption of blockchain will only come through simplicity, and Stratis Identity offers a streamlined way to verify one’s identity through popular social media accounts, using pre-existing Microsoft, LinkedIn or Google account information,” explains Stratis CEO Chris Trew. “Once one’s true identity is established through our app, a Stratis Identity can be shared securely without ever exposing any specific user’s sensitive personal data.”

Stratis explained that its app works by creating a permanent, unique record of a person, company or organization’s identity while simultaneously providing layered, permission-only access to the information. Each online social media profile has information linked to it (username, e-mail, job title, etc) stored by the account provider.

Two things happen on the Stratis blockchain when a user creates credentials with Stratis Identity, the company stated:

“First, a unique, immutable address belonging to you is created on the Stratis blockchain. Second, any confirmation of your information is encoded as a custom, hashed transaction,” Stratis stated. “Only a string of numbers and letters is placed on the blockchain, no personal information is stored – just metadata linking to your Stratis Identity.”

Wanchain CEO Jack Lu: Why 2.0 is a Milestone for the Entire Blockchain Industry

Wanchain CEO Jack Lu Why 2 0 is a Milestone for the Entire Blockchain Industry

The world’s first interoperable blockchain was launched today by Wanchain in Amsterdam. At the pre-launch, in London on Thursday, Blockchain News caught up with Wanchain’s CEO, Jack Lu, to find out why this is such a significant milestone not just for the company, but for the industry as a whole.

Blockchain News: Wanchain has an ambitious event schedule lined up, what are you trying to achieve? 

Jack Lu: I have an engineering background and I’ve been focusing on the product for, at least, the past six months. After we launched Wanchain 1.0 and went live in January this year, we were very focused on developing the product for 2.0, which is our biggest milestone–a cross-chain– and we’re ready to launch our mainnet in just a few days. We’ve been doing pre-launch events, touring the world, telling people we are the first ones in the world to reach this milestone. This milestone is huge, not only for our project but also for the industry. So that is why we have been doing this world tour—to promote our own chain and, at the same time, to bring all these projects—the ecosystem of Wanchain—with us. The Wanchain ecosystem is very, very important. That’s why, in the past few weeks, we’ve visited three cities in Asia. This is my fourth city in this world tour. After this, we’ll go live and I’ll go back to development and the team will continue the tour.

Blockchain News: Please tell us a little about how you became involved in blockchain and how you started Wanchain. 

and just followed their project. I became the developer of their community in Austin, Texas. At the same time, I was also introduced to the opportunity to be the co-founder and CTO of Factom. At the time, I made a decision to invest all my Bitcoins into Ethereum and invest all my time into the Factom project. Luckily enough, both these projects were a huge success after a couple of years. As you know, the price of Ethereum went up through the roof and so did Factom. 

In 2016, I decided to pursue my own dream, I wanted to launch my own project and I set up a company called WanGlue China and started looking at what space I wanted to be in and what I wanted to do. It just fitted really well, this Wanchain idea. It slowly matured. I had an idea but I wasn’t sure it could be done. I had a research team and we looked into this for a long time. Finally, we found a solution—a very generic solution—to enable us to connect or integrate with any blockchain with one single mechanism or design. The technology is called secure multi- party computation and also threshold key sharing technology. This technology allowed us to connect with pretty much any blockchain, including private chains, which is very important because a lot of traditional financial organizations, enterprises, would rather use enterprise solutions—private consortium chains—and these assets will be like the intranet of the old days. It’s just a set of computers which are connected, they are not interconnected with the rest of the world. Once we get these blockchains connected with the outside world… to really make this an internet, that’s how the old internet evolved–that’s the path we have to get across. So, I saw that requirement and we basically picked the solution that will allow us to interconnect not only with the public chains like Bitcoin and Ethereum, but also with private chains. We found a way. In 2016 we found a solution and we started incubating the solution called Wanchain. 

WAN stands for Wide Area Network, anyone who studied computing will know, it’s trying to connect a bigger network, connecting all theses intranets and creating something called the internet of blockchains, connecting all these siloed islands. Private chains are siloed islands and also Bitcoin and Ethereum. It seems like they’re global but actually they’re islands. Each one of them speaks different languages and they don’t talk to each other. So, we need to have some kind of generic solution that will interconnect with all these private chains and also public chains, and that is very powerful. 

At the same time, I found that getting them connected may not be the whole solution, we need something more than that. Because I was a strong believer in Ethereum, I figured to create something called a “programmable digital economy” is so important. I wanted to create smart contracts that can extend to all these blockchains; smart contracts that can be executed across different blockchains. 

In any economic activities–we call them digital economies–privacy is the most important thing because there are a lot of violations in privacy, including big companies like Facebook and Google. A lot of blockchains, like Bitcoin and Ethereum, don’t have privacy features, they have something like pseudo-anonymity, users activities can be still be traced. For enterprise businesses, privacy is just a must-have. I saw that and that’s the future for any blockchain, you must have privacy protection. At the same time, the government, or any other authority, will be able to audit private transactions. So, we created privacy protection that will allow the authority [to do this] as long as the transacting parties agree. They can provide something called the “view key” that will allow the authorities to audit private transactions.

Blockchain News: You’re working, then, towards a future where there will be regulation?

Jack Lu: Certainly.

Blockchain News: What sort of timeframe are you working towards? When do you think it will happen?

Jack Lu: Pretty quickly. I think that as long as we are connecting with the private chains, the governments can come and say, “Well, first you have to do KYC/AML [Know-Your-Customer/Anti-Money-Laundering], you have to have your identity verified in order to conduct certain transactions, like trading certain assets and getting certain financial access”. But the thing is, even with their real identity, people want to have privacy, they don’t want anyone to trace or track their transactions, their activities. But once the government wants to audit, you want to provide proof that “Here, I conducted all of these legally, I pay my taxes”. So, we need to create an infrastructure that is capable of complying with all these regulations. 

With all these requirements in mind, we came up with a solution. The solution’s just three key technologies: privacy protection, cross-chain and smart contracts. We think they will be able to fulfill all these requirements. Earlier this year, we completed two of them; we implemented private smart contracts. Now, in July, we’ve implemented the third one, it’s called cross-chain. So we’ve basically got the three key technologies, for all the requirements that we’ve talked about for the digital economy, and we think that these three technologies will solve pretty much all the issues. And now we are here, we’ve accomplished all the things we have promised to the community. Voila, we are here and ready to launch our key pillar. 

Blockchain News: That’s impressive. Are you keeping to schedule?

Jack Lu: Pretty much on schedule. I’ve been in IT, in the software development business, since the late 90’s, more than 20 years. I know things are never right on time, there are always some problems here and there. For blockchain, security is most important, we want to make sure there are no security flaws and, since we launched [1.0] in January, there are zero problems so far. And we’ve heard of so many issues for many blockchains. I hope that the issues won’t come for us. 

Blockchain News: What steps have you taken to avoid these kinds of problems?

Jack Lu: We take extra steps. Before we launched in January, we took two months to test the environment. It took us one month to do alpha testing and before that our community teams had already conducted vigorous testing—internally first, before we released to the public. It’s the same thing for 2.0. Actually, our alpha test network was ready two months ago. And the beta network was ready a month ago. We’ll just try our best. I’m sure that no problems will happen. 

Blockchain News: You have an incubator, WanLabs, now, as well. There’s been some questioning that maybe you’re focussing too much on that at the expense of the technology. How would you answer these criticisms? 

Jack Lu: To create our infrastructure, which I call Wall Street 2.0, if nobody comes, then it’s useless, right? So we’ve got the infrastructure ready, the basic technology is ready–that’s not enough. For this Wall Street 2.0 infrastructure to succeed, we’ve got to have a lot of buildings and a lot of people come here and create all these applications, to create real use cases. So that’s why were want to have the WanLab program and bring all these projects with us and grow the community together. The project team owns the core technology but we don’t own the network, the community does. We need to bring all these community members into the ecosystem. We own this ecosystem together and we need to build it together. It’s a natural process. If nobody comes, then we’ve failed. So we have to build this together.

Five ICOs to Watch: Hero Node, The Abyss, VideoCoin, TTC Protocol and ATN

Published

on

By the end of Q2 in 2018, blockchain will still be soaring in popularity despite the recent plunge of Bitcoin and other mainstream cryptocurrency. There are increasing numbers of new blockchain projects launching, varying from gaming to artificial intelligence.

There are five projects worth mentioning. They are ATN, TTC Protocol, Hero Node, The Abyss and VideoCoin.

ATN, a global artificial intelligence project, has not set a ICO goal, while The Abyss, a gaming project, and TTC Protocol achieved 85% and 90% of their ICO goals, respectively. HeroNode and VideoCoin are the only two projects to get 100% to their ICO goal. Three of them are not rated, whereas HeroNode and TTC Protocol are rated as Medium Interest.

Among those projects that started a month ago, HER is worth highlighting. HER token was issued by Hero Node, a next generation decentralized Blockchain fog computing platform. At press time, the HER token price is $0.0226232 (+0.24%), equal to 0.0000428901 ETH or 0.00000333 BTC. Its 24-hur volume is $55,177 with a market cap of $9,153,646.

IcoDrops reported that HeroNode has generated $21,765,720 of its goal $21,800,000 (100%) during the ICO.

What is Hero Node? A new approach to DApp development…

Hero Node is a cross-blockchain, cross-platform development solution for DApp. It is based on the hero protocol and its vision is to integrate different public blockchains, somewhat akin to the Alibaba Cloud in the blockchain industry.

Hero Node introduces a new generation of decentralized computing based on what we call “fog computing,” and the HER token paves the way for developers to build on top of this platform. By building a cross-chain and cross-platform solution, Hero Node empowers developers to build DApps without needing to be experts in smart contracts.

Guoping Liu, the CEO and founder of Hero Node, summarized this opportunity and gaping hole in the market, saying, “The blockchain company who solves the tricky task of DApp development will dominate this next decade.”

How does this actually work on HeroNode? Developers can build a DApp based on Qtum, Ethereum IPFS or other DApps linked to public chains and they can be run on iOS, Android and HTML5. Developers can use this interoperability to build DApps without needing to delve deep into the highly-specialized architecture of blockchain development.

A Technical Guide to HeroNode

Hero Node’s development framework and underlying blockchain technology allows developers to pack applications into hash addresses and ensure the immutability of transactions. There are a few core elements at play:

• Public chain service: The Hero protocol integrates various public chains (ETH, QTUM, EOS) into a consistent API interface, allowing developers on Hero Node to develop their new business DApps without any understanding of these underlying blockchains.

  • Storage service: Hero Node aims to create a node ecosystem on IPFS. In this ecosystem, data is generated by development, and applications are broken down and stored in various places on the Internet. This model for decentralized storage is like a drop of water poured into the sea: as long as the Internet exists, that data cannot be lost. Once a user wants to extract their data, Hero Node selects the nearest node to process that data and then promptly returns it to that user.
  • Decentralization: Most blockchain applications still use domain names, calling into question how ‘decentralized’ they really are. Hero Node will help developers create their applications on distributed networks and run these applications by applying torrents. When an application becomes a torrent, neither the data nor the public chain are revocable, which allows the application to exist on the network forever. It is completely different from this arguably centralized, existing software (mode) life cycle (even for existing DApps).•Cross-platform application development tools: Blockchain applications will eventually come to grips with ordinary users who have no exposure to the technology and ecosystem. The experience must be seamless, and it will require blockchain applications to be installed and used on a user’s mobile phone, just like other existing common applications on iOS and Android. With its modular tools, Hero Node facilitates this seamless experience. By making the actual development process more streamlined across platforms, both developers and end users can experience decentralized applications without the clunky and siloed interface of existing platforms.This is a paid post provided by U.S. Blockchain.
