Composition high school with blockchain as the core

1. In terms of governance, the blockchain has no centralized organization or institution, and the rights and obligations of any node are equal. The blockchain prevents a few people from controlling the whole blockchain system through consensus mechanism, so the blockchain is decentralized in governance. From the perspective of architecture, blockchain is based on peer-to-peer network. The damage or loss of any node will not affect the operation of the whole system, and the system has excellent robustness. Therefore, blockchain is architecture decentralization. In terms of storage, blockchain is a kind of distributed storage technology. Data is distributed and stored in all nodes and a consensus is reached. There is no one center holding the right of storage. Therefore, blockchain is also a storage decentralization
blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

2. 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

3. Yes, decentralization, which is the core of blockchain. It is a new application mode integrating distributed data storage, transmission, identification, encryption, trust and security technologies. At present, it is mainly used in electronic currency

6. It's fire chain finance. News updates are fast and the quality of articles is high.

7. Many relationships between people are based on trust, such as friend relationship, cooperation relationship, transaction relationship, etc
take trading activities as an example. In the past, the two sides who did not trust each other usually chose an intermediary to guarantee a transaction. In the mobile Internet era, we chose Taobao shopping because Alipay provided us with an intermediate guarantee. We chose to drop dripping because it provided us with information matching.
however, these intermediaries are centralized and have their own interests. Sometimes they are not so reliable and trustworthy. Theoretically, Alipay's centralization of accounting has been artificially falsified. Part of the reason for Didi's troubles is that they only think from their own standpoint
what blockchain does is the machine of trust, which replaces the role of trust intermediary with code, ensures the fairness and justice of the whole system through consensus mechanism and distributed accounting, and provides a trust without trust
for example, in the future, people can abandon the intermediate platform and realize point-to-point docking and free trading through blockchain. Shopping does not need to go through an intermediary, and taking a taxi does not need to go through Didi. In this way, we can really achieve "no middleman to earn the price difference" and rece the cost.

8. In essence, blockchain is a distributed database system with cryptography technology, multi-party participation, common maintenance and continuous growth, also known as distributed shared ledger. Each account page in the shared ledger is a block, and each block is full of transaction records. The blocks are connected closely, forming a chain structure; If you don't understand this area, I suggest you learn the basic knowledge from Xuan, Ling, network and company! At present, there are few people who really understand technology and business. Many people follow suit and learn. They are not clear about the definition of blockchain, so they start to attack the blockchain field. Some of them are learning technology, and some of them choose to invest in the blockchain market
