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

Embodiment 1

[0025] Figure 4It is a flow chart of the block chain errata method for serially adding blocks as a whole provided by the embodiment of the present invention. The execution subject of this method may be a system with data processing function, including a terminal and / or a server. The embodiment of the present invention relates to the concept of extended blockchain. The so-called extended blockchain is: when a new block is generated for newly generated data, the part of the blockchain linked by the new block in the entire blockchain is called extended blockchain. In this embodiment, a complete blockchain may include an extended blockchain, or an extended blockchain and at least one copy block linked to the extended blockchain. These copy blocks are only for the purpose of errata correcting the block body data of the blocks in the extended blockchain, and are not regarded as new blocks generated for newly generated data.

[0026] Such as Figure 4 As shown, the errata method ...

Embodiment 2

[0047] Figure 7 A schematic diagram of an errata system for a block chain with blocks serially added as a whole provided by an embodiment of the present invention, the block chain includes an extended block chain, or an extended block chain and at least one block chain linked to the extended block chain Copy block. Such as Figure 7 As shown, the blockchain errata system that increases the number of blocks serially includes: an errata request receiving module 710, a copy block generation module 720 and a copy block linking module 730, wherein:

[0048] The errata request receiving module 710 is configured to receive a data errata request for the block body data of blocks in the currently formed extended blockchain, the data errata request includes: the first data to be corrected is in the extended blockchain The location information of the first data, and the second data after errata on the first data; the copy block generation module 720 is used to base on the block body d...

Abstract

The embodiment of the invention provides an error correction method and an error correction system for a block chain of an overall serial increased block chain, and belongs to the technical field of block chains. The method comprises the steps of receiving a data error correction request for block body data of a block in the currently formed extended block chain; generating a duplicate block corresponding to current time of data error correction according to the block body data of the first block or the block body data of the existing duplicate block corresponding to the first block where first data is located in the data error correction request and second data; and using any block in the extended block chain as a parent block, or using the duplicate block positioned at the tail end of the block chain corresponding to the first block as the parent block, and using the currently generated duplicate block to serve as a child block, and linking the currently generated duplicate block into the block chain. According to the scheme of the method and the system provided by the embodiment of the invention, error correction of the block body data in the original block is achieved by serially increasing the duplicate block into the block chain.

Description

technical field [0001] The embodiments of the present invention belong to the technical field of block chains, and in particular relate to a method and system for correcting block chains in which blocks are added serially as a whole. 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 ...
