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 4 It is a flow chart of a block chain errata method for adding blocks in parallel provided by an embodiment of the present invention. The execution subject of this method may be a system with data processing functions, 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 of the bl...

Embodiment 2

[0046] Figure 7 Schematic diagram of an errata system for a block chain that adds blocks in parallel 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 copy area linked to the extended block chain Piece. Such as Figure 7 As shown, the errata system of the block chain that increases blocks in parallel includes: an errata request receiving module 710, a copy block generating module 720 and a copy block linking module 730, wherein:

[0047] 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 the errata is performed on the first data; the copy block generation module 720 is used to generate the current data er...

Abstract

The embodiment of the present invention provides a block chain correction method and system for adding blocks in parallel, which belongs to the field of block chain technology. The method includes: receiving block body data for blocks in the currently formed extended block chain data errata request; according to the block body data and the second data of the first block where the first data is located in the data errata request, a copy block corresponding to this data errata is generated, and the block body data of the copy block is higher than the The block body data of the first block, except that the first data is modified to the second data, other data correspond to the same; take any block in the extended block chain as the parent block, and The duplicate block is used as a sub-block, and the duplicate block is linked into the blockchain. The solution of the embodiment of the present invention is aimed at realizing the errata correction of the block body data in the original block by adding duplicate blocks in the block chain in parallel during the extension process of the existing 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 method and system for correcting block chains in which blocks are added in parallel. 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 said that...
