Everyone does blockchain

1.

Because the design of blockchain is a kind of protection measure, such as distributed computing system with high fault tolerance. Blockchain makes hybrid consistency possible. This makes blockchain suitable for recording events, titles, medical records and other activities that need to include data, identity management, transaction process management and provenance management. Blockchain has great potential for financial disintermediation and has great influence on guiding Global trade

extended data :

1. Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system

2. Blockchain is an important concept of bitcoin, which is essentially a disintermediated database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block

3. Blockchain - the original blockchain is a kind of decentralized database, which contains a list called blocks, with continuously growing and orderly records. Each block contains a time stamp and a link with the previous block. The block chain is designed so that the data can not be tampered with. Once recorded, the data in a block will be irreversible

2. There are a lot of blockchains in China, although compared with the number of enterprises in other instries, they are very few. For example, Yingtang Zhongchuang has a good reputation at present, mainly for the underlying technical services and instry solutions of blockchain. That is to say, an underlying blockchain is built, and an adaptation layer is built on it, so that enterprises can quickly establish commercial applications.

Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. 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 data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

if such technology wants to be put into application, the biggest problem is the "Impossible Triangle problem"

that is, scalability, decentralization and security cannot be achieved at the same time, and only two of them can be achieved

most of the existing public chain projects in the market are difficult to put into use on a large scale

4. First of all, I'd like to introce some well-known blockchain companies in China, and then I'll personally evaluate which one is good. You can judge for yourself

1. Bubi blockchain company, which is engaged in the underlying technical services and instry solutions of blockchain. That is to say, an underlying blockchain is built, and an adaptation layer is built on it, so that enterprises can quickly establish commercial applications. The underlying blockchain is self-developed. The consensus mechanism is pbft, TPS is 5000 transactions per second, UnionPay is 2000 transactions per second, and bitcoin is 7 transactions per second. Of course, different underlying architectures lead to different performance, because Bubi's commercial blockchain pays more attention to performance. At present, Bubi is mainly used in digital assets, supply chain finance, supply chain traceability, public notary and other fields< 2. Bumeng blockchain. Theoretically, bumeng should be regarded as the proct line of Bubi, but Bubi is mainly engaged in the private chain, while bumeng is an alliance chain. So separately, bumeng is Bubi's layout in digital assets. The underlying technology is Bubi blockchain, but it encapsulates the blockchain according to the scene and provides API interface for enterprises. Enterprises issue their own assets on it. According to the characteristics of blockchain, they can freely circulate their assets. At present, some enterprises such as sunshine insurance, Qianxiang finance, crowdsourcing, Haohuo, etc. have joined in, and the assets in them include insurance policies, integral points, and so on Financial procts and so on. Finally, it is estimated that this platform will break through the barriers between assets, and the end users can freely use and transfer these assets. This is an interesting way for the blockchain instry, because it has both the opening of public chain and the security of private chain

Third, only chain, which is a commodity ID management cloud platform based on blockchain technology, provides enterprise users with commodity asset management, tracing, anti-counterfeiting verification, new supply chain management, etc. in the form of baas. Simple understanding is that only chain has done the content of "supply chain traceability" of Bubi blockchain

four, concentric mutual aid, concentric mutual aid is a mutual aid security platform, put some mutual insurance related information into the blockchain, and users can apply to become nodes, participate in bookkeeping, and maintain their own data

5. Xiaoyi is a decentralized network protocol based on blockchain technology, which digitizes the assets and interests of the real world, and carries out financial business such as registration and issuance, transfer transaction, clearing and delivery through point-to-point network

these five blockchain companies are probably well-known in China, and I personally recommend bumeng

first, bumeng uses the underlying technology of Bubi blockchain, which is very promising in the instry. It has the largest number of landing applications in China. Enterprises can not only use the blockchain technology at low cost (just call the interface, it seems that it is free), but also use the resources inside. Think about being on the same chain with many enterprises and docking resources in the future, User transformation should not be easy

Second, Weilian and Tongxin Huzhu focus on one field, and do not provide underlying technology and instry solutions. That is to say, if you are in this instry or can be used in the upstream and downstream of this instry, you can not be used in other fields. Take mutual security field as an example, zhongtuobang and zebra Club both choose bumeng. Of course, if it is an investment, you can consider it

Third, Xiaoyi, why not recommend Xiaoyi, because Xiaoyi is an open source project, and we all know the domestic business environment, especially when the instry is just beginning to develop, and the domestic market is different from that of foreign countries, Xiaoyi has gone through two rounds of ICO, which will be a great worry in the future operation, and at present, Xiaoyi has not been applied in practice, We have made a Fada platform, which has not been used by any company yet (guess it may be related to the factors of open source, who dares to open their data completely). Of course, the open attitude of Xiaoyi is worth encouraging. Although I guess the advantages and disadvantages of the code are well understood by peers, it is not clear

Fourth, why is there no recommendation for Bubby? Bubby has raised 30 million yuan a while ago, because Bubby is more open and has more resources. Of course, if the business requires high privacy, it can also choose Bubby blockchain

finally, for all my hard work, choose me!

5. Classification and application of blockchain:
1. According to different scenarios, design systems and attribution, blockchain is generally divided into three categories: public chain (public service), private chain (focusing on the application of an enterprise or instry) and alliance chain (generally belonging to an instry or a supply chain)
2. It is basically divided into three kinds of applications:
blockchain applications of well-known enterprises: (Netease blockchain cat (game), thunderbolt chain customer, storm's cool broadcast cloud (BFC points), Renren's social rrcoin, Meitu's e-commerce + blockchain, 360's router, cheetah and other well-known enterprises)
start up companies based on blockchain (Ethernet wallet, Babbitt, fire coin)<
social public applications (the bank has set up a research and development laboratory)
current market situation and development of blockchain:
currently, blockchain applications in the market still focus on issuing "token", realizing "point management"
, pet games, etc., with relatively single functions, and the data of blockchain related apps is even less, and more of them are financial apps.

6. What are the specific aspects? Blockchain is a technology. What are your classmates doing
blockchain projects, blockchain media, or what? Another possibility is digital currency. In any case, you'd better make a clear understanding of the blockchain before you decide. There are also a lot of people who cheat by using blockchain gimmicks. You have to distinguish them
you can learn about blockchain in some places, such as cryptography, finance and so on.

7. virtual currency is not supported at the national level in China. Although some people have made money by using virtual currency, the risk is too great in case of danger

8. It started with the underlying technology of bitcoin

9. Yu Lingxiong has done a good job in blockchain, advocating long-term value investment and opposing speculation.

10. Blockchain:

in a narrow sense, blockchain is a kind of chained data structure composed of data blocks connected in sequence according to the time sequence, and it can not be tampered with and forged by cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
Application of blockchain:
1. The art instry

ascribe allows artists to declare their ownership by using blockchain technology, issue numbered and limited edition works, and aim at digital forms of any type of artwork. It even includes a trading market where artists can buy and sell through their websites without any intermediary services
2. Bitproof is the most advanced application of document timestamps in recent years, which will make the traditional notarization method a thing of the past. Bitproof offers more services than free versions including blocksgin and originstaemp, including one for intellectual property. Interestingly, bitproof recently cooperated with an it school in San Francisco to put their students' academic certificates on the blockchain, completely redefining how to handle and use diplomas and student certificates
3. Development instry
colu is the first enterprise to allow other enterprises to issue digital assets. They can "token" all kinds of assets, which has a profound impact on many people. Although the free bitcoin wallet couperparty also allows simple tokens to be issued and traded among other wallet holders, the tokens of colu can be set with various states and types, can be detached from or returned to the system, and can be stored on BitTorrent's network when the data stored on the blockchain is too large.
