Shenzhen blockchain top 50

1.

blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum

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. In essence, it is 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 bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

extended data

according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:

1. The blockchain with the whole network open and without user authorization mechanism is called public chain

2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain

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

alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain

blockchain features

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

2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

3. Independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention

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

5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously

2. 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.

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

Blockchain is a new application mode of distributed data storage, which is an important concept of bitcoin. At present, there are 35 stocks associated with the blockchain concept in the A-share market, of which 6 blockchain concept listed companies are traded on the Shanghai Stock Exchange, and 29 blockchain concept listed companies are traded on the Shenzhen Stock Exchange

according to the correlation of blockchain, the leading stocks of blockchain concept stocks are most likely to be born from Xinchen technology, luyitong and Sifang Jingchuang

Xinchen Technology: on September 29, 2016, the company said in the interaction that the company is now doing research and development of blockchain technology

Lu Yitong: the company plans to raise 67.9691 million shares of additional shares of RMB 24.57 per share, and the total amount of supporting funds will not exceed RMB 1.670 billion, which will be used to pay the cash consideration of this transaction, construct the block chain ASIC chip instrialization project, artificial intelligence ASIC chip R & D center, chip proct marketing and service network, etc

Sifang Jingchuang: on May 31, 2016, the inaugural meeting and the first general meeting of the financial blockchain cooperation alliance (Shenzhen) was officially held in Shenzhen Wuzhou Hotel, and the company was one of the members of the meeting

5. Play guest cloud, flow treasure box, storm broadcast control cloud, star magic box, Xiaorui family cloud, travel and entertainment treasure box and so on, the modes are almost the same
BSC cloud box is also one of them, which is worthy of special introction
from the point of view of time nodes, BSC cloud box is one of the earlier models. Gamer cloud came out earlier than BSC cloud box. However, in a major revision later, BSC cloud box mode was still used. From the perspective of risk control, BSC does the same as gamer cloud
but BSC cloud box is 100 times and 10000 times better than other procts - dividend mechanism
in short, the BSC system uses your idle computing power and traffic to make profits, and then distributes the profits to everyone according to the amount of contributed computing power and traffic
that's what everyone says, but how many people really give dividends
the dividend in the first quarter of 2019 has been completed. I didn't get the dividend because of my own nonsense and disagreeing with the government, but some friends around me got the dividend, the six figure level, and the highest one got the seven figure level. Of course, other people also made a lot of investment and contribution
this is the first blockchain proct that I have seen since I came into contact with blockchain, which really pays dividends. I am convinced that I will not mess with it in the future, and I will follow suit in a down-to-earth way.

6. At present, blockchain technology is mainly used in finance, medical treatment, authentication, smart contract, sharing economy, digital assets and other fields. In the future, it may break through the application of all walks of life, such as Internet, energy, proof of existence, social media, government departments, kindness, health, music right, etc Applications in many fields such as consumers: there are relatively few blockchain technology R & D companies, and Yingtang Zhongchuang is an innovative company in blockchain technology R & D. Due to the powerful application effect of blockchain, many enterprises are ready to join in the research and development of blockchain, which also confirms the unlimited potential of blockchain in the future development of enterprises.

7. In May 2018, under the guidance of the Department of information technology and software services of the Ministry of instry and information technology, China blockchain technology and instry development forum announced the standard of "blockchain and distributed ledger technology reference architecture", becoming the first domestic blockchain basic standard under the guidance of the government in the world. For investment opportunities in the instry, CITIC Securities said that in terms of instry investment, the instry is still in the stage of infrastructure construction, but progress has begun to accelerate. The procts of start-ups are not mature, the performance is not optimistic, the instry valuation is generally high, and the instry inflection point has not yet arrived. Now they are in the accumulation stage of blockchain technology learning curve, and they are looking forward to the implementation of explosive application scenarios
concept stocks: Tuowei information, Huasheng Tiancheng, Westone.

8. Due to the powerful effect of blockchain and many application fields, there are not a few enterprises carrying out the research and development of blockchain technology
according to the latest news, bat and Jingdong have announced the layout of the blockchain field, while Yingtang Zhongchuang, which uses blockchain technology for system development, has already built the blockchain platform internally, which is mainly applied to five scenarios, including finance, Internet of things public services, charity and supply chain. Alibaba's plan is to track the sales path of goods through the blockchain and establish a verification network to prevent counterfeiting. Jingdong applies blockchain to anti-counterfeiting traceability and food safety. In addition, supply chain finance is also an alternative direction.

9. Block even system development company which is stronger, several are good.

10. It's Xunlei. Many years ago, Xunlei transformed the blockchain. Because of its first mover advantage, Xunlei has obtained world-leading technological achievements. The emergence of blockchain makes Xunlei find its "right way to open". In such a hot situation of domestic blockchain, I think Xunlei can take the lead. Xunlei has been technology-oriented for many years, forming technology precipitation, and blockchain technology has a strong natural correlation with P2P technology and distributed technology of shared computing on which Xunlei started, so Xunlei can rise rapidly in this field. According to the current momentum, as the blockchain instry environment develops step by step, we believe that Xunlei's technical advantages will usher in more opportunities for transformation and embodiment, and enter a new development cycle.
