Credible pseudo-center storage system based on blockchain

The invention discloses a credible pseudo-center storage system based on blockchain. The credible pseudo-center storage system comprises a blockchain node and a center storage node, wherein the blockchain node is a common block chain node, is responsible for completing various affairs of the block chain, and also has a function of interacting with the central storage node; the central storage node is responsible for receiving data information from the blockchain node, locally storing complete data and providing a query function for a user; on the basis of ensuring that the data cannot be modified and traceable, a central node is maintained through the blockchain node, pseudo-centralized storage of the data is realized, redundancy of common node data is greatly reduced, and meanwhile, authenticity of the data queried from the central node is ensured. 本发明公开了一种基于区块链的可信伪中心存储系统，本发明包括区块链节点、中心存储节点；所述的区块链节点为普通区块链节点负责完成区块链的各项事务的基础上，还具有与中心存储节点交互的功能；所述的中心存储节点为负责接收来自区块链节点的数据信息，并在本地保存完整的数据，对用户提供查询的功能；本发明在保证数据不可修改和可追溯的基础上，
