Summary of foreign blockchains

1. What are the representatives of the current blockchain alliance inventory

In the past two years, blockchain alliances have emerged, what are the representatives?
In the early stage of the development of the blockchain industry, many enterprises and institutions formed blockchain alliances to share the research results of blockchain technology and seek wider application of blockchain technology.
In the past two years, blockchain alliances have emerged. As of July 2017, there are currently R3 composed of more than 40 international banks, hyperledger initiated by the Linux Foundation, located in the core of China’s Internet The Zhongguancun Blockchain Industry Alliance in the hinterland, the China Ledger Alliance jointly initiated by 11 institutions, the Golden Chain Alliance jointly established by 25 financial institutions, the Russian Blockchain Alliance known as the “Russian version of R3”, seeking cooperation with Micro The blockchain micro-finance industry alliance at the financial integration point, the Qianhai International Blockchain Ecosystem Alliance led by the Shenzhen Qianhai Authority, and the Lujiazui Blockchain Financial Development Alliance located in Lujiazui.
Everyone gathers firewood and the flame is high, and many institutions and talents join in to promote the vigorous development of the blockchain.

2. What are some of the more famous blockchain games in the world

Blockchain games should be games developed by Tencent and developed by Tianmei Studio.

3. What are the blockchain platforms?

Does the blockchain platform depend on the blockchain information? Here is Amway Crypto Finance, general chain circle currency circle dapp, etc. information can be seen.

4. What are the current applications of foreign blockchain in the financial field

2016 is also the first year of blockchain development, and various venture capitals have invested billions of dollars Funds invested in blockchain startups and projects. Foreign IBM, Deloitte, Deutsche Bank, etc. have released their own blockchain designs. Nasdaq is already using blockchain technology. Related applications have appeared in securities, voting, data storage, logistics and other industries.
Domestic first-line financial and Internet companies such as Wanxiang Finance, LeTV Finance, Ping An Finance, etc. also joined the technology feast. Small businesses such as Eurofins crowdfunding are at the forefront of utilizing blockchain technology.

5. What are the famous blockchain public chains in China?

Little Yi Blockchain, Laikelib, etc. It seems to be very interesting.

6. Is it true that the foreign blockchain trading market is speculating on this BGCC?

I heard that the BGCC is speculating in the foreign blockchain exchanges. I should go to a foreign exchange. can be realized. Set up a little first and wait for the fry to go high. The current market value of this BGCC is only 1 yuan, and it is not difficult to increase it by 10 times.

7. At present, what are the more reliable blockchain public chains in China

In the past, whenever we mentioned going to the blockchain, we always thought of foreign products, such as Ethereum, but when I talk about this topic again today I think more about China’s own blockchain technology.

At present, the mature application of blockchain technology is more concentrated in some public chain projects, because many application projects are developed based on this, so I think the current global One of the general directions of the implementation of the project is the public chain project. It is still too early to talk about maturity. After all, Bitcoin and Ethereum are still very blocked. There are still many old problems that have not been solved, and many new problems will appear. The more well-known ones are Bytom, Ulord (the project is abroad, but the technical provider is provided by the domestic company Hunan Tianhe Guoyun Co., Ltd.), Quantum Chain, Xiaoyi NEO, Gongxinbao, etc.

Ulord is a peer-to-peer value transfer public chain. By building the underlying architecture of the blockchain and the digital resource distribution protocol, it supports third-party developers to build their own applications on top of its open source protocol, and cooperates with many industries. Partners work together to build a complete ecosystem of blockchain technology and applications.

Based on various rules and protocols created by Ulord, it is convenient to graft various application scenarios of digital resources including text, pictures, music, video, software, etc., providing information creators and consumers with direct docking platform. Third-party developers can build their own economic system in Ulord, or they can build various applications around Ulord, and use UlordToken in Ulord as the certificate in the system.

For example, an experience sharing platform can be built on Ulord, the experience sharer will price the published experience, the person who obtains the experience information trades on the platform, and every fee paid to the experience sharer will arrive immediately. Account; product promoters can publish advertisements on Ulord, price the advertisements, and those who are interested in the advertisements and click the advertisements can get a certain income and so on. Different from the previous mode of information transmission, which requires the help of platforms or other centralized institutions to spread and profit, the intermediate links are removed, and information providers and consumers are directly connected through Ulord, which ensures the maximization of the interests of the original creators.

8. What are the public blockchains

Blockchains include public blockchains, joint (industry) blockchains, and private blockchains. Public chain peer-to-peer electronic cash system: Bitcoin, smartContract and Decentralized Application Platform: Ethereum.

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of cryptographic methods associated with each other. The generated data blocks, each of which contains a batch of Bitcoin network transaction information, is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

(8) Extended reading of foreign blockchain summary

According to the degree of centralization of the blockchain network, there are three different application scenarios of the blockchain:

1. A blockchain that is open to the whole network and has no user authorization mechanism, said It is a public chain;

2. Authorized nodes are allowed to join the network, and information can be viewed according to their permissions. It is often used in inter-organizational blockchains, called alliance chains or industry chains;

3. All nodes in the network are in the hands of one institution, which is called a private chain.

Consortium chains and private chains are also collectively referred to as permissioned chains, and public chains are referred to as permissionless chains.

Blockchain features

1. Decentralization. Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control. Except for the self-contained blockchain itself, through distributed accounting and storage, each node realizes information self-verification, transmission and management. Decentralization is the most prominent and essential feature of blockchain.

2. Openness. The foundation of blockchain technology is open source. In addition to the encrypted private information of transaction parties, blockchain data is open to everyone. Anyone can query blockchain data and develop related applications through public interfaces. System information is highly transparent.

3. Independence. Based on consensus specifications and protocols (similar to various mathematical algorithms such as the hash algorithm adopted by Bitcoin), the entire blockchain system does not rely on other third parties, and all nodes can automatically and securely verify and exchange data within the system without the need for any human intervention.

4. Security. As long as 51% of all data nodes cannot be controlled, network data cannot be manipulated and modified arbitrarily, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes.

5. Anonymity. Unless required by legal regulations, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transmission can be carried out anonymously.

9. Which are the seven major blockchain applications that will affect the future world?

Blockchain is the value return of the Internet.
In 1989, Berners-Lee developed the World Wide Web. The foundation of the World Wide Web is based on the principles of openness and fairness. But today, after a lapse of 28 years, various monopoly situations have begun to appear on the global Internet, and the principle of openness and transparency of the Internet has been trampled on without restraint.
In China, the Internet has officially entered the era of “US-Soviet hegemony”, and Tencent and Alibaba have almost formed a monopoly. Some platforms have successively leaked user privacy. Recently, two well-known companies have been reported to compete for user data. To change all this, a new technological force is urgently needed, and the blockchain came into being in this context.
From a technical point of view, blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.
The so-called consensus mechanism is a mathematical algorithm that realizes the establishment of trust between different nodes and the acquisition of rights and interests in the blockchain system. In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner according to time sequence, and cryptographically guarantees a distributed ledger that cannot be tampered with and cannot be forged.
In a broad sense, blockchain technology is to use the block chain data structure to verify and store data, use distributed node consensus algorithm to generate and update data, use cryptography to ensure the security of data transmission and access, and use A new distributed infrastructure and computing paradigm for programming and manipulating data by smart contracts composed of automated script code.
From this point of view, the blockchain application projects that can affect the future world must have the following common characteristics:
1. The field has extremely high demand for data security
2. Where The field has extremely high requirements for data privacy
3. The operation and calculation process needs to be traceable and non-tamperable
4. It can reduce social costs
5. Open attitude, everyone can contribute and participate
6. Has its own independently issued token
7. The industry has been highly prosperous in the Internet landscape
Through sufficient industry data research and extensive sampling research, we list the following eight areas that can change the world Blockchain application direction and outstanding representative projects.
I. Finance
br />The core value of blockchain application in the financial field: promoting anti-money laundering and customer identity verification.
In the innovation and application exploration of blockchain, finance is the most important field, and blockchain technology has broad applications in digital currency, payment and settlement, smart contracts, financial transactions, Internet of Things finance, etc. prospect.
Take Taobao shopping as an example, the payment process requires Alipay to realize trusted and secured transactions, but because Taobao and Alipay belong to the same family, this credit foundation is manipulated in Ali’s own hands. If the Alipay guarantee platform is replaced with a “trusted super system” to make transactions intuitive and secure, there is no need for third-party guarantees. The emergence of the blockchain just makes this idea a reality.
Bitcoin is the most widely used and most successful application of blockchain technology at present. Because of its immutable time stamp and the characteristics of being open to the whole network, it has been widely trusted by financial industries such as banking, securities, and insurance. In recent years, it has skyrocketed wildly, and even bitcoin has become a legal currency in many countries.
2. Games
Blockchain applies the core value of the game field: returning game rights to game players.
Decentralization of blockchain technology, smart contracts, asset transactions and other technical features can well solve the current problem of game data and user data privacy leakage in the game industry, promote the preservation of virtual digital currency in games, and realize user Fair value sharing with game development platforms.
In foreign countries, blockchain technology has been widely used in game currency payment. For example, Fragoria, a game with eight million players, has launched GameCredits’ blockchain payment gateway to provide the first cryptocurrency payment solution for the game industry.
Three, social
The core value of blockchain application in the social field: let users control data by themselves and prevent privacy leakage.
Think about why we have just browsed a certain shopping website, and always receive similar advertisement pop-ups on other social platforms, because the big data platforms whose data privacy is monopolized have carried out shameful sales.
The purpose of the application of blockchain technology in the social field is to change the control of social networks from centralized companies to individuals, to realize the change from centralization to decentralization, and to firmly grasp the control of data in the hands of the user.
The Israeli light social APP software Synereo fully guarantees user privacy and security with the help of anonymized blockchain network and its embedded token mechanism. At the same time, it uses tag tokenization and personalized pricing to help people reshape social network image, interpersonal relationship, identity and cognition.
4. Copyright
The core value of blockchain application in the copyright field: reshaping the protection of intellectual property rights.
Blockchain technology records all transactions in blocks, and the records cannot be tampered with, so all transactions can be tracked and queried, which ensures the transparency of transactions on the blockchain and avoids Users in the network illegally use content protected by intellectual property rights. For original creators, this is a more convenient, safer and cheaper way of copyright protection.
? Currently, blockchain technology is mostly used for copyright protection of digital music. PledgeMusic, an online music platform, has released a comprehensive blueprint for a global decentralized ledger and fair trade music database, which can fully address the issues of ownership, payment and transparency.
V. Cloud Computing
The core value of blockchain application in the field of cloud computing: to promote the construction of public trust infrastructure.
China Academy of Information and Communications Technology believes that the combination of blockchain and cloud is also an inevitable trend. The combination of blockchain and cloud has two modes, one is the blockchain on the cloud, and the other is the blockchain in the cloud. The latter, namely BaaS, Blockchain-as-a-Service, refers to the direct provision of blockchain as a service by cloud service providers to users.
In the future, more and more cloud service companies will integrate blockchain technology into the cloud computing ecosystem. By providing BaaS functions, it will effectively reduce the deployment cost of enterprise application blockchain and lower the initial threshold for innovation and entrepreneurship. .
6. Sharing economy
The core value of blockchain application in the field of cloud computing: building user trust for the platform.
Blockchain is a distributed and consistent storage system that realizes a transparent and true credit management system under the P2P business model. The core is decentralization and de-trust, to crack the trust pain points of the sharing economy. P2P online loans, used car transactions, accommodation sharing and other sharing economy segments have all begun to try.
With the help of smart contract technology, blockchain can automatically perform operations that meet certain conditions, and can also “share” more commodities, greatly reducing the cost of contract establishment and execution.
Tencent is applying smart contracts to bicycle rental, house sharing and other fields. If such smart contracts are applied to today’s popular bicycle sharing field, it may��Bring new changes to the entire industry.
7. Digital Advertising
The core value of blockchain application in the field of digital advertising: to achieve precise advertising and ensure that user privacy is not violated.
The natural advantages of blockchain technology in data immutability, decentralization and security show that it has a natural grafting advantage with digital advertising. Smart contracts can effectively improve the efficiency of advertising transactions while combating digital advertising fraud.
metacrypto metadata advertising chain is the world’s first mobile advertising platform based on blockchain technology. MetaCrypto adopts a decentralized business model, does not rely on any centralized intermediaries, does not rely on the trouble of bidding ranking, and realizes freedom Submit the online advertising contract, and the delivery effect does not need to worry about being tampered with by any link and falsely delivered by the channel party.
Users set personalized metadata on their own private devices, private and sensitive information will only be kept on their own devices, and part of the metadata that can be publicly used for contract matching will be synchronized by the business blockchain , while protecting the privacy of each user, the user can trigger the advertiser’s advertisement playing contract locally and obtain certain additional rewards from it.
