Problems solved by technology

However, in some cases, when the block body data in a block on the blockchain does have errors, or due to the special needs of regulatory or policy departments, it needs to be modified and corrected, but if the data is forcibly Modification will inevitably lead to the failure of the consistency verification of the blockchain, resulting in a contradiction between modifying the block data and the consistency verification of the blockchain

Abstract

The embodiment of the invention provides a block chain error correction method and system used for modifying the existing block body data of a block chain, belonging to the technical field of block chains. The block chain error correction method used for modifying the existing block body data of the block chain comprises the following steps: receiving a data error correction request for the currently formed block body data in the block chain, wherein the data error correction request comprises the location information of the first data to be corrected in the block chain and the second data after correcting the first data; modifying the first data in the block chain to the second data; generating a error correction record according to the data error correction request; and storing the error correction record in a corrigenda outside the block chain, wherein the corrigenda outside the block chain and block chain have a relevance relationship, used for a inquirer to inquire the block chain combined with the corrigenda outside the block chain. The scheme provided by embodiment of the invention aims at modifying the block body data in the generated block chain, and realizing the error correction of the block body data in the block chain in the case of completing the verification of the consistency of the block chain.

Description

technical field [0001] Embodiments of the present invention belong to the technical field of block chains, and in particular relate to a block chain correction method and system for modifying block chains, that is, block body data. Background technique [0002] With the continuous development of the Internet, blockchain technology has emerged as the times require. It is an Internet database technology with the characteristics of decentralization, openness and transparency. Specifically, the essence of blockchain technology is a method of data storage, transmission and certification that is decentralized and resides in a distributed structure. Data blocks are used to replace the current dependence of the Internet on central servers, so that all data changes or transaction items are It is recorded on multiple ledger nodes at the same time. Due to the distributed peer-to-peer network without a central control point, and the method of distributed collective operation, it can be...
