Blockchain articles
blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects
on January 10, 2019, the state Internet Information Office issued the regulations on the management of blockchain information services. In October 24, 2019, ring the eighteenth collective learning of the Central Political Bureau, general secretary Xi Jinping stressed that "block chain as an important breakthrough in core technology and independent innovation", "accelerating the development of block chain technology and instrial innovation". "Blockchain" has entered the public field of vision and become the focus of social attention

Application of blockchain Finance:
since 2016, the major financial giants have also carried out blockchain innovation projects to explore the possibility of applying blockchain Technology in various financial scenarios. In particular, Puyin group took the lead in creating a "blockchain +" standard digital currency
standard digital currency refers to the process of assets identification, evaluation, right confirmation and insurance completed by a third party organization, which is written into the blockchain through careful digital algorithm to form the standard corresponding relationship between assets and digital currency, which is called standard digital currency
in order to realize the great leap forward development of blockchain finance, promote the new development of China's economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that has been struggling for generations, Puyin group will hold the Guiyang strategic development ceremony of Puyin blockchain finance in Guizhou on December 9, 2016
the meeting will discuss the realization of digital circulation of assets by blockchain, the financial transaction mode of blockchain, and the application of blockchain services and social public instry. This conference will mark the beginning of the application of blockchain finance and the change and development of the new financial ecology
on June 1, 2020, Xinhua news agency was authorized to broadcast the "overall plan for the construction of Hainan free trade port" issued by the CPC Central Committee and the State Council, which will "actively participate in the formulation of international rules for cross-border data flow, and establish standards and rules for data rights confirmation, data trading, data security and blockchain finance" as one of the key tasks of Hainan free trade port before 2035
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
this is usually the summary of the professional reports, but what is the specific form
first of all, no matter how large a system or how small a website is, there is a database behind it. So who will maintain this database? In general, who is responsible for the operation of the network or system, then who is responsible for the maintenance
if it is wechat database, it must be maintained by Tencent team, and Taobao database is maintained by Alibaba team. We must think that this way is natural, but blockchain technology is not
secondly, blockchain technology is also known as distributed ledger technology. If we think of the database as a Book: for example, Alipay is a typical account book, any change of data is bookkeeping. We can think of database maintenance as a very simple way of accounting
in the world of blockchain, everyone in the blockchain system has the opportunity to participate in bookkeeping. The system will select the person with the fastest and best bookkeeping in 10 seconds or 10 minutes, and the person will record the changes of database and account book in a block
we can think of this block as a piece of paper. After confirming that the records are correct, the system will link the fingerprint of the data in the past account book to this piece of paper, and then send this piece of paper to all other people in the whole system. Then, over and over again, the system will look for the next person with fast and good bookkeeping, and everyone else in the system will get a of the whole ledger
as like as two peas, each computer has the same rights as the owner, and the whole system will not collapse e to the loss of contact or downtime by a single person.
as like as two peas in the book, it means that all data is transparent and open. Everyone can see what changes are in every account. Its very interesting feature is that the data can't be tampered with. Because the system will automatically compare, it will think that the same number of books with the largest number are real books, and a small number of books with different numbers are false books
in this case, it is meaningless for anyone to tamper with his own account book, because unless you can tamper with most nodes in the whole system. If there are only a few nodes in the whole system, it may be easy to do so. But if there are tens of thousands and hundreds of thousands of nodes and they are distributed in any corner of the Internet, unless someone can control most computers in the world, it is unlikely to tamper with such a large blockchain
I don't know if I can understand such a popular explanation

nowadays, many swindlers use the concept of district fast chain to hype, and then pull investment to cheat money. I really don't know what's the use of these people investing in an anti cheating system, which doesn't generate value.
