1. The popularity of the whole
blockchain CHANYE has declined since 19 years. The currencies of several large platforms have tended to be stable. The security of smart contracts on small platforms is difficult to guarantee, and the risk is high. It is easy to attack and collapse. If you invest rather than speculate, you'd better not choose.
2. Public chain, also known as "public chain", refers to the blockchain that anyone in the world can enter the system at any time to read data, send confirmatory transactions and compete for bookkeeping. The public chain is generally considered to be "completely decentralized", because no indivial or institution can control or tamper with the reading and writing of data in it. In terms of application, blockchain public chain mainly includes bitcoin, Ethereum, super ledger, most counterfeit currencies and smart contracts. The ancestor of blockchain public chain is bitcoin blockchain, which has the following characteristics:
1, open source code
upload the code to GitHub, and everyone can get complete blockchain data by downloading, Accept the test of the public
2, complete decentralization
anyone can become a node, each node is open, everyone can participate in the calculation of the blockchain, any node is not permanent, but phased, and any center is not mandatory for nodes. Anyone can read and send transactions, and transactions can be effectively confirmed on the blockchain. Anyone can participate in the consensus process. The consensus process determines whether a block can be added to the blockchain and the exact current state. Everyone can get financial reward from it, which is proportional to their contribution to the consensus process. These public chains are generally considered to be "completely decentralized"
3. Developing decentralized applications
through this public chain, developers can easily develop centralized applications. Public chain can protect the rights and interests of users from the influence of program developers
3. At present, the mature application of blockchain technology is more concentrated in some public chain projects, because many application projects need to be developed based on this, so I think public chain projects are one of the major landing directions in the world. It's still too early to talk about maturity. After all, bitcoin and Ethereum are still blocked, and many old problems have not been solved, There will be many new problems. The well-known ones are Biyuan chain, ulord (the project is abroad, but the technical party provides it in the domestic company, Hunan Tianhe Guoyun Co., Ltd.), quantum chain, Xiaoyi Neo, gongxinbao, etc.
4. I think bitcoin China is a reliable platform. It is the first and largest bitcoin trading platform in China. It is operated by Shanghai satuxi Network Co., Ltd. and was established on June 9, 2011. The team members are mainly from China, Silicon Valley and Europe
bitcoin world is based on credit, and Chinese brands of bitcoin have high credibility in the global bitcoin field
5. Ha ha ha ha ha ha What is it, you don't know,... Airdrop is lying, boasting Not fatal,
6. At first, people were more interested in his design concept, but there was no shortage of fresh objects in the world. But once people were cut leeks, they would slowly think about this thing. He has been there for so many years, and it should graally return to zero, Even Ma Yun's technology application can't catch up, and it's still popular in the world. It's a joke. The state's attitude towards him is not to fight or support him.
7. PHP you learn, where are easy to find a job, website developers in China's demand is very large. If you want to engage in software development, I suggest you engage in top-level development, learn some C / C + +, and say it's popular. You need a career plan to engage in software, because with the growth of age, your energy and brain power may not be as good as young people. There are two ways: you can be promoted to project manager, supervisor, architect, etc., or be replaced by young people.
8. Tokenlon is a sub brand of consenlabs. At present, tokenlon includes two moles, IEX and DEX, which are the flash exchange function based on kyber network and the currency exchange function based on 0x protocol.
9. Currently, UOS is preferred. Because eth, EOS, AE have all gone up! UOS is the basic platform of blockchain which combines the advantages of eth + EOS.
10. STM32 Shenzhou IV is RMII, you can find his schematic diagram, network card chip is dm9161ae
