As we all know, blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The person in charge of blockchain technology research and development of China Enterprise Tongbao said that the so-called consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights between different nodes in the blockchain system.
Blockchain (Blockchain) is an important concept of Bitcoin, which is essentially a decentralized database and the underlying technology of Bitcoin. A blockchain is a series of data blocks that are associated using cryptographic methods. Each data block contains the information of a Bitcoin network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner according to time sequence, and is cryptographically guaranteed to be an untamperable and unforgeable distributed ledger.
Broadly speaking, blockchain technology utilizes blockchain data structures to verify and store data and utilize distributed nodes.
