Blockchain is a term in the field of information technology. In essence, it is a shared database, data or information stored in it, and has the characteristics such as "irreplaceable", "left marks", "can be traced", "open transparency" and "collective maintenance".

1. Public blockchain
The public blockchain (Public Block Chains) refers to: Any individual or group in the world can send transactions, and transactions can get the blockchain that can get the blockchain Effectively confirmed that anyone can participate in their consensus process. The public blockchain is the earliest blockchain and the most widely used blockchain. The virtual digital currencies of the major Bitcoins series are based on the public blockchain. Essence
2, united (industry) blockchain
The industry blockchain (Block Chains): The nodes of multiple pre -selected nodes are specified inside a group as the bookkeeper. The node jointly decided (the pre -selected node to participate in the consensus process). Other access nodes can participate in the transaction, but the questioning process (essentially the custody of the accounting, but only becomes a distributed bookkeeping, how much the pre -selected node, how to determine each one for each one. Block bookmakers have become the main risk points of the blockchain), and anyone else can make a limited query through the API opened by the blockchain.
3, private blockchain
Priving block chains: Only use the general ledger technology of the blockchain for bookkeeping. It can be a company or an individual. The chain is not much different from this chain and other distributed storage schemes. Traditional finance wants to experiment and try private blockchain, and the application of public chain, such as Bitcoin, has been industrialized, and the application of private chain application products is still being explored.
