This article will briefly introduce the block chain (blockchain) and use Python to do a simple implementation. What is a block chain In a nutshell, a block chain is a permanent, irreversible modification of a record of encrypted data (chunks) stacked (chained) in chronological order. Specifically, the block chain is made up of a string of data blocks that are generated by a cryptographic method, each containing a hash of the previous block, starting with the Genesis block to connect to the curre

This article I use Python to implement a local block, to achieve a complete block chain also need to do a distributed server, a lot of things. First, the transactions are stored in chronological order, and the transaction of the bits and other encrypted currencies that are traded using the block chain are saved in time and are publicly stored. In layman's parlance, a block chain is a public database in which new data is stored in a container called a block and added to an immutable chain (hence
