Who endorses blockchain

1.

blockchain is an important concept of bitcoin. It is essentially a disintermediated 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 the information of a bitcoin network transaction, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies

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

extended data:

the evolution mode of blockchain is as follows:

& 9642; Blockchain 1.0 - digital currency

▪ Blockchain 2.0 - digital assets and smart contracts

▪ Blockchain 3.0 - Implementation of distributed applications in various instries

blockchain features:

1. Disintermediation. Due to the use of Distributed Accounting and storage, there is no centralized hardware or management organization in the system, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system

2. Openness. The system is open. In addition to the private information of all parties to the transaction is encrypted, the data of the blockchain is open to all. Anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

3. Autonomy. Blockchain adopts consensus based specifications and Protocols (such as a set of open and transparent algorithms) to enable all nodes in the whole system to exchange data freely and safely in a de trusted environment, so that the trust in "people" is changed into the trust in machines, and any human intervention does not work

The information can not be tampered with. Once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid. Therefore, the data stability and reliability of the blockchain are extremely high

5. Anonymity. Because the exchange between nodes follows a fixed algorithm, the data interaction does not need to be trusted (the program rules in the blockchain will judge whether the activity is effective). Therefore, the counterparties do not need to make the other party trust themselves by disclosing their identities, which is very helpful for the accumulation of credit

Recently, MIT announced that it will launch MIT financial technology laboratory with several top technology companies in the world on July 18, 2018. Its main research directions include blockchain development, privacy security, database, encryption system, etc. ant financial is the only Chinese founder

In an exclusive interview with people, Jiang Guofei, director of ant technology laboratory, said that the former NEC technology VP, who has been wandering in Tokyo Bay and New York Bay for the past 15 years, said that China and the United States are almost on the same starting line in the independent research and development of Frontier core technologies such as blockchain, This is a sight that has never been seen before“ Whether it is Tokyo Bay, New York Bay or San Francisco Bay, they all rise in the blowout of Japan and the United States' comprehensive national strength. Now it's time to go to China, so I'm back. "

On March 20, it was reported that recently, an all-star team composed of Grammy award winners and music procers officially launched the blockchain music right project tune to solve the problem of right protection and profit distribution that plagued the entire music instry

at present, the development and application of domestic blockchain is still in an early stage, the infrastructure of blockchain is not perfect, and the instry application is also in the exploration stage. Instry insiders suggest that we should seize the development opportunity of blockchain technology, and rationally view the implementation progress and application scenarios of blockchain technology, so as to avoid the investment risk caused by excessive speculation

4. The earliest designer of China's virtual currency blockchain is Mr. Zhang Ronghuan. You can go online: Zhang Ronghuan's gene of digital economy indicates that bitcoin blockchain mode is the gene of digital economy in the top-level design of ecological civilization.

5. Blockchain is a technical solution to maintain a reliable database collectively through centralization and distrust in the past. This technical solution mainly allows any number of nodes in the participating system to generate a series of data blocks by using cryptographic methods. Each data block contains all the information exchange data of the system in a certain period of time, and generates a data fingerprint to verify the validity of its information and link to the next database block
blockchain is a technical solution similar to NoSQL (non relational database). It is not a specific technology and can be implemented through many programming languages and architectures. There are many ways to realize blockchain, including pow (proof of work), POS (proof of stake), dpos (delegate proof of stake), etc
the Internet will make the global interaction more and more close, accompanied by a huge trust gap. At present, the existing mainstream database technology architecture is private and centralized, which can never solve the problem of value transfer and mutual trust. Therefore, blockchain technology is likely to become the next generation of database architecture. Through decentralization technology, we will be able to complete the great progress of mathematical (algorithm) endorsement and global mutual trust on the basis of big data
as a specific distributed data access technology, blockchain technology uses multiple nodes in the network to participate in the calculation and recording of data, and verifies the validity of their information (anti-counterfeiting). From this point, blockchain technology is also a specific database technology. The Internet has just entered the era of big data, but at present, big data is still in a very basic stage. But when we enter the stage of blockchain database, we will enter the era of real big data with strong trust endorsement. All the data in this is of indestructible quality, and no one has the ability or need to question it.
