What is a common mechanism? The mainstream consensus algorithm block chain have?

CodePudding user response:

Mechanism of the so-called "consensus", is in a period agreed on the sequence of things of a kind of algorithm, for example, we in the school to run for monitor of the class by voting, the voting process and methodology, is a kind of common mechanism, let the people of the whole class who agreed as our monitor, block the application of the chain in order to achieve the layer "consensus" reached a consensus, is a specific methodology, and write the program,

This is a bit long, but have seen a video, description is quite understandable, https://quant.la/Video/View/56/block chain 100 q. HTML, interest may have a look again, delete, reprinted
From barter to COINS
- want to block chain but to retrieve information system is too fragmented
- want to learn more block chain but existing science is too obscure
Have more fun and system science block chain?
100 q series animation block chain, to block chain system, suitable for block chain you'd like to know you,
Chain block is a kind of decentralized value transfer system, the data on the block chain highly tamper-proof sex, after so many nodes authentication before use, once the record cannot be modified, block every time value of the chain transmission is clear records, and can be traced back, block chain can build trust between each center, some people say that block chain can change the world, like the Internet
File management, patent protection, and other areas of the social management, items, security, and other areas of the Internet of things, charitable donations, and other areas of the public are using block chain on the characteristics of information transparency and tamper-resistant,
