Blockchain solicitation

1. With the development of the whole blockchain instry, it is impossible to go back to the past. bitcoin is far less likely to collapse than it is to reach $100000. Recently, a listed company has undergone earth shaking changes e to the application of a blockchain. Such a magic story will also stimulate more and more giant companies to pay attention to the blockchain, thus promoting the development of the whole instry. The Chicago Mercantile Exchange will launch the bitcoin futures contract in December, which may be another major turning point. It may mark a fundamental change in the game rules and market structure of the whole instry. Although we have missed the legend of bitcoin, from the perspective of the whole blockchain instry, it may be just the beginning to bring blockchain assets into our view of asset allocation.

2. Legally, China only has restrictions on the issuance and speculation of currency in the blockchain, because a large amount of black money in China, such as those of corrupt officials, will be illegally obtained overseas by means of digital currency. If the blockchain digital currency is opened up and traded casually, it is estimated that China can not control the outflow of black money. Now the law encourages blockchain. In addition to legal currency, China encourages and supports other blockchain technologies.

3. Blockchain and blockchain technology have been widely accepted and used by people, but they have little knowledge about blockchain and blockchain technology, and they are even at a loss about the working principle and operation mode of blockchain. Perhaps I've read many related reports, many professional terms, and I'm not very clear about them. Here, I'll explain them in a popular way
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
