Guo Hongcai talks about blockchain

1. Because at this stage, all the right issues in China are in an exploratory stage, and the system is not yet complete, so the blockchain can not solve the right problem.

2. In the era of blockchain 1.0
this generation of blockchain technology has no application function, which is to issue currency, represented by bitcoin
in the era of blockchain 2.0
blockchain 2.0 is a programmable blockchain
the era of blockchain 3.0
blockchain 3.0 is beyond the financial instry, covering all aspects of social life.

3. Is this the college entrance examination?

4. I just want to say that blockchain is a kind of technology, which is hard for outsiders to understand. For example, the provident fund data sharing platform developed by fun chain technology connects the data of provident fund centers in nearly 500 cities across the country, so that citizens in these cities can handle provident fund access and personal tax dection business in different places. In the future, they will no longer have to run in two places

5.

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

6. If bitcoin is money, blockchain is the account book, which records the transfer records of bitcoin. However, blockchain is not only unique to bitcoin, but also has blockchains of other digital currencies and other application fields. What else can I ask you if you don't understand
