Abstract

The present invention provides a block chain-based data processing method, device, and storage medium. The method includes: the first node processes the data to be processed sent by the second node, generates block data, and determines where the block data is located. the first block number in the first node; the first node broadcasts the block data to at least one third node, and receives a first message sent by each of the third nodes, and the first message includes the the second block number of the block data in each of the third nodes; the first node determines whether to write the block data into the In the first blockchain of the first node. The block chain-based data processing method, device and storage medium provided by the present invention can prevent the bifurcation phenomenon of data in each node and ensure the consistency of data in each node.

Description

technical field [0001] The present invention relates to computer application technology, in particular to a block chain-based data processing method, device and storage medium. Background technique [0002] Blockchain is a distributed database system in which nodes participate. It uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access. , A new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and manipulate data. [0003] In the existing technology, when a node generates block data, it will write the block data into the locally stored blockchain. In order to ensure that the data of each participant is consistent, the node will broadcast the generated block data , so that other participants, after receiving the block data broadcast by the node, write the blo...
