Blockchain data storage method, system, device, and readable storage medium

Abstract

Provided are a blockchain data storage method, a system, a device, and a readable storage medium. The method includes: obtaining, by a block file system, a target block serial number and target block contents of a target block, the block file system including a directory region and a data region, a size of each cluster in the data region being the same as a block size of blockchain, the directory region storing mapping relationships between block serial numbers and cluster addresses; sequentially allocating a target cluster address to the target block, and recording, in the directory region, a target mapping relationship between the target block serial number and the target cluster address; and sequentially writing the target block contents into the data region according to the target cluster address.
