Abstract

The embodiment of the invention belongs to the block chain technology, and relates to a block chain data updating method and device, computer equipment and a storage medium, the method comprises the following steps: sending an on-chain data updating request to each node, the on-chain data updating request comprising on-chain data updating information for a to-be-updated block; when it is determined that verification is passed according to the returned request verification result, updating event information and a replacement block are generated based on the on-chain data updating information and the request verification result, and the replacement block comprises an updating node signature and a verification passing node signature; broadcasting update event information to each node; when it is detected that the newest block contains update event information, storing the block number of the newest block into a replacement block; sending a block verification request for the replacement block to each node; and when it is determined that verification is passed according to the returned block verification result, replacing the to-be-updated block with the replacement block to complete block chain data updating. According to the invention, updating of the data on the block chain is realized.

Description

technical field [0001] The present application relates to the field of block chain technology, and in particular to a block chain data updating method, device, computer equipment and storage medium. Background technique [0002] Blockchain is a distributed shared ledger and database, which is characterized by decentralization, openness and transparency, and is immutable. Although the immutability of the blockchain can ensure data security, there is also a risk of abuse. Some data, such as private data, trade secrets, illegal information, abnormal information, etc., are not suitable for being sent to the blockchain. If these data are sent to the blockchain, due to the unmodifiable nature of the traditional blockchain, it will become very difficult to update and correct the data on the chain, and the data on the chain may also cause serious impact. Contents of the invention [0003] The purpose of the embodiments of the present application is to propose a block chain data ...
