China's listed companies with the largest number of blockchai

1. IBM, Microsoft, Oracle, Accenture, Tencent, Alibaba, Jingdong, network, etc. have all done it. Many large banks, including Ping An Bank, have also launched their own blockchain solution platforms or solutions. However, it should be added that large companies do not mean strong technical strength, because blockchain is still in the hot stage of concept in the world. Unicorn blockchain companies are likely to emerge in the future, such as EOS in foreign countries and honeycomb chain of Fanrong technology in China. The efficiency of TPS and packing into blocks may be much higher than that of large companies.

2. Alibaba
IPR daily, an intellectual property media, recently released a report, which listed the number of blockchain invention patents published in the world from January 1, 2019 to June 30, 2019, among which China ranked first, accounting for 67% of patent applications. Alibaba ranked first with 322 patents, followed by Ping An of China, with 274 patents, Third, nchain has 241 patents.

3. Shandong bianke Information Technology Co., Ltd. is a software development company with excellent technology
[blockchain exchange]
blockchain technology application research and development, exchange wallet system app development, blockchain technology is actually a new type of Internet. Why is it a subversion of the Internet? Because the Internet solves the problem of information transmission, and the blockchain solves the problem of value transmission. Yuanzhongrui's blockchain system has a lot of value transfer in the development of blockchain, such as distributed ledger, decentralized trust, smart contract, etc. What kind of society will it build in the future
the answer is: a distributed business and self disciplined society. Blockchain features first, decentralization; Without the intervention of the third party, it can realize people to people, point-to-point transaction and interaction
Second, information can not be tampered with; Once the data information is written into the block, it cannot be changed or revoked< Thirdly, it is open and transparent; In a very short time, the block information will be copied to all the blocks in the network to realize the data synchronization of the whole network, and each node can trace back all the transaction information of both sides in the past
Fourth, collective maintenance; In the whole blockchain network, all roles work together to maintain the reliability and security of the whole blockchain information
fifthly, reliable database; Only by mastering 51% of the nodes of the whole system can we tamper with the blockchain information, which is obviously impossible, because there are many participants in the whole system, and mastering so many nodes can not be realized at high cost
the characteristics of blockchain bring great opportunities for the financial instry. With the help of blockchain, the transformation of the internal application scenarios of the instry can bring three main benefits:
1) cost rection: communication cost: the centralized trading market generally needs the participation and coordination of the central clearing system, securities companies, exchanges and banks, and the coordination cost is very high, Through the signature and encryption technology of blockchain, the information can be shared and the coordination cost can be reced; Operating costs: recing labor and paper vouchers, improving automation through smart contracts, and centralizing coordination also bring very high operating costs
2) improve efficiency: the settlement cycle is very fast. When the financial transactions realized through blockchain technology are confirmed, they are actually the process of combining clearing, settlement and audit. The openness, transparency and non tamperability of the blockchain can preserve the operation traces, keep the supervision records and audit traces, and provide convenience for supervision and audit
3) risk rection: the transaction confirmation on the chain is the completion of clearing and calculation, which greatly reces the transaction risk. The research and development of blockchain technology application and the development of exchange wallet system app

the definition of blockchain

in a narrow sense, blockchain is a kind of chained data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography

broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code

there are many channels to learn blockchain

① you can buy some books related to blockchain, learn some knowledge related to blockchain, take notes in your spare time, and consult relevant information

② watch some videos of blockchain on the Internet, the contents of which are easy to understand, with relevant examples, It's also a very good way to learn

③ you can take part in some offline blockchain learning exchange meetings, or take part in some training courses, and some teachers will answer questions for you

to sum up,

all roads lead to Rome. There are many channels to learn blockchain, and the best one is suitable for you
