On the real problem of blockchain technology testing

1. If you are interested in blockchain technology, you can learn the knowledge of cryptography at the beginning, and learn how to strengthen contracts other than trust through numbers. This is the most basic principle of blockchain. Then you can look at the programming books, understand the basic code, and do simple programming. After that, you can download some common blockchains, Study its code arrangement, see how it adds contracts, and make simple modifications to build its own smart contracts. Of course, if you are only affected by the recent price and hype and decide to join the instry, I suggest you learn more about the Bulls who hype it, listen to their opinions, and learn how others reap!

2. The following points are the characteristics of the blockchain summarized by jinwowo group:

1 - Decentralization: because the blockchain relies on each node to achieve system maintenance and ensure the authenticity of information transmission, it is based on distributed data storage without centralized management by a certain center, Therefore, the attack and tampering of a node will not affect the healthy operation of the whole network

2-DE Trust: the establishment of a connection between any two nodes does not need to trust each other's identity, and the data exchange between the two sides does not need the basis of mutual trust. Since all nodes in the network can act as "supervisors", there is no need to worry about fraud

3 - extensible: blockchain is an underlying open source technology, on which various kinds of extension, decentralized and distrusted applications can be realized<

4 - anonymization: the two sides of data exchange can be anonymous, and the nodes in the network can exchange data without knowing each other's identity and personal information

5 - Security and reliability: because the activities between any nodes are supervised by the whole network, and the database adopts distributed storage, for hackers, first, they can't disguise and cheat, Second, we can't control the network only by conquering a node.

3. Several successful ones are block chain housing rental platform in xiong'an New District, SMIC block chain public service platform in Changsha high tech Zone, and block chain Real Estate Registration Platform in Loudi. Hunan has done a good job in the application of block chain technology in the whole country. There are mature and successful application cases in provincial capitals and prefecture level cities.

4. Both became families

5. Hunan now has two well-known blockchain projects: one is the SMIC blockchain public service platform in Changsha, and the other is the blockchain real estate platform in Loudi. The promotion and popularization of these two platforms does not mean that the whole of Hunan has entered the era of blockchain 3.0. It can only be said that what they are doing belongs to the procts and applications that should be in the era of blockchain 3.0.

6. Most of the digital currency trading platforms give priority to the development of PC version, and most of them support PC client. At present, most of the digital currency trading platforms are like this. When the platform develops to a certain extent, the company's popularity and recognition are very high, and the capital is strong, the development will be considered

at present, okcoin is the platform that I know has developed mobile app. Fuyuan currency trading platform, bitcoin era and bitcoin China all support PC version.

8. Bitcoin plate is big, equivalent to the stock market, I think it is not suitable for novices. virtual currency is still worth playing now. For example, the flow of virtual currency is relatively small, which is more suitable for people who are not willing to save and who are not willing to take too much risk.
