Why are major Internet companies doing blockchain?

Because the design of blockchain is a protective measure, such as a highly fault-tolerant distributed computing system. Blockchain makes mixed consistency possible. This makes the blockchain suitable for recording events, titles, medical records and other activities that need to include data, identification management, transaction process management and origin certification management. Blockchain has great financial disintermediation potential and has great influence on guiding global trade.

1, blockchain is a new application mode of distributed data storage, point-to-point transmission, * * * * identification mechanism, encryption algorithm and other computer technologies. The so-called * * * knowledge mechanism is a mathematical algorithm for building trust and acquiring rights between different nodes in the blockchain system.

2. Blockchain is an important concept of Bitcoin, which is essentially a disintermediated database as the underlying technology of Bitcoin. Blockchain is a series of data blocks related by cryptography, and each data block contains a bitcoin network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

3. Blockchain-The original blockchain is a decentralized database, which contains a list called blocks, and the records are growing and arranged neatly. Each block contains a timestamp and a link to the previous block. The blockchain is designed so that data cannot be tampered with. Once recorded, the data in the block will be irreversible.
