we can compare the development of blockchain with the development of the Internet itself. In the future, something called finance Internet will be formed on the Internet. This thing is based on blockchain, and its precursor is bitcoin, that is, traditional finance starts from private chain and instry chain (LAN), Bitcoin series start from the public chain (WAN), all express the same concept - digital asset, and finally converge to an intermediate equilibrium point
the evolution mode of blockchain is as follows:
blockchain 1.0 - digital currency
blockchain 2.0 - digital assets and smart contracts
blockchain 3.0 - Dao, DAC (blockchain self-consistent organization, blockchain self-consistent company) - & gt; Blockchain Society (Science, medical, ecation, etc., blockchain + AI). At present, classified editing blockchain is divided into three categories, among which hybrid blockchain and private blockchain can be regarded as generalized private chain:
public blockchain
public blockchain means that 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 blockchain, and it is also the most widely used blockchain at present. The virtual digital currencies of bitcoin series are all based on public blockchain, and there is only one corresponding blockchain in the world
consortium blockchains
instry blockchains: multiple preselected nodes are designated as bookkeepers within a certain group, and the generation of each block is jointly determined by all preselected nodes (preselected nodes participate in the consensus process). Other access nodes can participate in transactions, but not the bookkeeping process (essentially, trusteeship bookkeeping), It just becomes distributed accounting, the number of preselected nodes, how to determine the bookkeeper of each block to become the main risk point of the blockchain), and anyone else
it will lose
