Problems solved by technology

[0003] The purpose of the present invention is to provide a method and system for decentralized chaining of large data, which cuts large data into small pieces of data and uploads small pieces of data to the chain one by one. Each small piece is only stored on a certain node of the blockchain network. The data stored by the nodes is different and not repeated, which solves the problem of redundant storage of blockchain data and improves the efficiency of data uploading to the chain

Abstract

The invention provides a big data disperse uplink method and system, and the method relates to the field of big data, can be applied to the technical field of block chains and the financial field, and specifically comprises the steps: obtaining an uplink request of a user and a to-be-uploaded data file, and calculating the data file through a Hash algorithm according to the uplink request to obtain a first Hash value; comparing the first hash value with a hash value carried in the uplink request; when the first hash value is consistent with the hash value carried in the uplink request, segmenting the data file into a plurality of continuous data blocks according to a preset rule, and calculating a second hash value of each data block through a hash algorithm; and forming the data blocks into a chain structure through the second hash values of the data blocks, and uploading the data blocks in the chain structure to different nodes in the block chain network for consensus storage.

Description

technical field [0001] The invention relates to the field of big data, can be applied to the field of block chain technology and the financial field, and especially refers to a method and system for decentralized chaining of big data. Background technique [0002] In the blockchain processing system, data uploading is usually to save the data on all blockchain nodes, and all blockchain nodes have the same data. This situation will bring about redundant storage problems, resulting in unnecessary waste of storage space, especially for large data on-chain, the waste of storage space is even more serious, and it brings efficiency problems on the chain, and a new type of storage space is urgently needed The data on-chain method solves this problem. Contents of the invention [0003] The purpose of the present invention is to provide a method and system for decentralized chaining of large data, which cuts large data into small pieces of data and uploads small pieces of data to ...
