1. That's a good question. Let me give you an example. For example, when I deposit 100 yuan in the bank, the data of this deposit is only recorded in the bank's database, which can't be obtained by others, namely "central bookkeeping". The blockchain is a distributed accounting, a new information recording technology, and it is "encrypted" and "distributed". The data does not exist in a center, but is stored once on the computer of the whole network. For example, if I transfer 100 yuan to you, I will shout to all the computers in the whole network. Let's record the accounts together, that is, "Distributed Accounting".
2.

blockchain is a digital account book that can be jointly bookkept, and will record all transactions that have occurred and have been unanimously recognized by the system it's the same as the whole family. You're bookkeeping, and your father and mother are also bookkeeping. They can see the general ledger, but the saved information can't be tampered with any more

In 2008, Nakamoto first proposed the concept of blockchain subsequently, blockchain has become the core component of electronic currency bitcoin, which serves as the public account book for all transactions. By using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independently

extended data:

type of blockchain

1, public blockchain

any indivial or group in the world can send transactions, and transactions can be effectively confirmed by the blockchain, and anyone can participate in its consensus process. Public blockchain is the earliest and the most widely used blockchain. The virtual digital currencies of bitcoin series are all based on public blockchain. There is only one blockchain corresponding to this currency in the world

2, Alliance (instry) blockchain

instry blockchain: multiple preselected nodes are designated as bookkeepers within a group, and the generation of each block is jointly determined by all preselected nodes (preselected nodes participate in the consensus process), and other access nodes can participate in the transaction, However, regardless of the bookkeeping process (in essence, it is still managed bookkeeping, only distributed bookkeeping, how many preselected nodes, and how to determine the bookkeeper of each block to become the main risk point of the blockchain), anyone else can conct limited query through the open API of the blockchain

3, private blockchain

only uses the general ledger technology of blockchain for bookkeeping. It can be a company or an indivial, and enjoys the write permission of the blockchain. This blockchain is not very different from other distributed storage schemes

3. At present, blockchain technology is in the stage of rapid development. In the past two years, China has invested a lot of funds and talents in this area
technical personnel can learn this technology, while non-technical personnel can start from the instry media and instry community
If an enterprise needs to develop blockchain applications, it can entrust a professional third-party company. In Guangzhou, today's technology is good.
4.

First of all, don't think too much about blockchain. It's a database storage system that is distributed all over the world and can work together. Different from the traditional database operation, where the read and write permissions are controlled by a company or a centralized hand (the centralized feature), blockchain believes that anyone who has the ability to set up a server node can participate in it. Gold diggers from all over the world deploy their own nodes locally and connect to the blockchain network to become a node in the distributed database storage system; Once joined, the node enjoys the same rights and obligations as all other nodes (decentralized, distributed features). At the same time, for those who carry out services on the blockchain, they can read and write to any node in the system. Finally, all nodes in the world will synchronize one after another according to some mechanism, so that the data of all nodes in the blockchain network is completely consistent

blockchain itself is a technology, so it can't be a fraud. Just like the normalized "P2P" finance in recent years, how many fraudsters are wearing the concept of P2P to illegally absorb public funds and cheat people's hard-earned money? But is "P2P" guilty? It's just an indivial to indivial mode of Internet finance. It not only creates profits, but also helps thousands of people get rid of poverty, so as to achieve a win-win situation between the poor and the poor. The problems of currency exchange digital currency trading platform

can not hinder the development of blockchain, such as simple payment verification, side chain, lightning network protocol and other technologies proposed and in-depth research, which has been the problem solved by blockchain

5. Because it comes from money. Virtual money is bought with real money. So it's also called coin there.
6. Bitcoin market suddenly soared, and now you can buy it. But you have to buy by yourself. Think about it, because bitcoin is a virtual currency. Market uncertainty, buy carefully.
7. "OK blockchain 60 lecture" is a blockchain popular science animation jointly proced by okex and sina science and technology. As the procer and distributor, okex uses its rich resources accumulated for a long time to build an easy to understand blockchain with professionals in the instry. It is only possible to learn. The main purpose of okex's move is to make the public better understand the knowledge of blockchain, Establish a correct understanding of the concept of blockchain.
8. Official account is official account. Official account is not available. If you want to know if a public number exists or whether a company has a public number, can you query through WeChat users? Step up: open the WeChat user page, click the plus sign on the top right-hand corner of WeChat, select the search type public number, enter the name company or related keywords you want to search for the official account, click the search results. Find official account official account of official account official based on the results of the survey, and notice whether the main information of public number is whether it is reliable or not. If the main body is OK and the official account has been certified by V, and the relevant content information is also found in the public number, the public number is the target public number. Click follow to follow all the public contents.
