Blockchain is a technology that is both old and young. In the beginning, it was just the exploration and experimentation of a group of tech geeks. From not being taken seriously at the earliest, to the subsequent fire, the blockchain has also verified its advanced nature here.

Blockchain originated from Bitcoin. On November 1, 2008, a self-proclaimed Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on P2P network technology, encryption technology , time stamp technology, blockchain technology and other electronic cash system architecture concepts, which marks the birth of Bitcoin. Two months later, the theory entered into practice, and the first genesis block with serial number 0 was born on January 3, 2009. A few days later, on January 9, 2009, a block with serial number 1 appeared and was connected with the genesis block with serial number 0 to form a chain, marking the birth of the blockchain.

In recent years, the world's attitude towards Bitcoin has been ups and downs, but the blockchain technology, one of the underlying technologies of Bitcoin, has been paid more and more attention. In the process of Bitcoin formation, blocks are storage units one by one, which record all the communication information of each block node within a certain period of time. Each block is linked by random hashing (also called hash algorithm), and the next block contains the hash value of the previous block. The result is called a blockchain.
