Blockchain English
blockchain is a digital account book that can be jointly bookkept, and will record all transactions that have occurred and have been unanimously recognized by the system it's the same as the whole family. You're bookkeeping, and your father and mother are also bookkeeping. They can see the general ledger, but the saved information can't be tampered with any more
In 2008, Nakamoto first proposed the concept of blockchain subsequently, blockchain has become the core component of electronic currency bitcoin, which serves as the public account book for all transactions. By using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independentlyextended data:
type of blockchain
1, public blockchain
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 and the most widely used blockchain. The virtual digital currencies of bitcoin series are all based on public blockchain. There is only one blockchain corresponding to this currency in the world
2, Alliance (instry) blockchain
instry blockchain: multiple preselected nodes are designated as bookkeepers within a group, and the generation of each block is jointly determined by all preselected nodes (preselected nodes participate in the consensus process), and other access nodes can participate in the transaction, However, regardless of the bookkeeping process (in essence, it is still managed bookkeeping, only distributed bookkeeping, how many preselected nodes, and how to determine the bookkeeper of each block to become the main risk point of the blockchain), anyone else can conct limited query through the open API of the blockchain
3, private blockchain
only uses the general ledger technology of blockchain for bookkeeping. It can be a company or an indivial, and enjoys the write permission of the blockchain. This blockchain is not very different from other distributed storage schemes
blockchain related applications include digital currency crowdfunding platform, coin Ying China, and asset custody system developed by China Post Based on blockchain technology.
