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 This is a flow chart of a method for errata for a blockchain that adds 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 an extended blockchain. The so-called extended blockchain is: when a new block is generated for newly generated data, the part of the blockchain linked to the new block in the entire blockchain is called an extended Blockchain. In this embodiment, a complete blockchain may include an extended blockchain, or an extended blockchain and at least one replica block linked to the extended blockchain. These duplicate blocks only serve the purpose of errata and correction of the block body data of the blocks in the extended blockchain, and are not regarded as new blocks generated for newly generated data.

Embodiment 2

[0046] Figure 7 This is a schematic diagram of an errata system for a blockchain that adds blocks in parallel provided by an embodiment of the present invention. The blockchain includes an extended blockchain, or an extended blockchain and at least one copy area linked to the extended blockchain Piece. Such as Figure 7 As shown, the errata system for the block chain that adds blocks in parallel includes: an errata request receiving module 710, a copy block generation module 720, and a copy block link module 730, wherein:

[0047] The errata request receiving module 710 is configured to receive a data errata request for the block volume data of a block in the currently formed extended blockchain. The data errata request includes: the first data to be errata is in the extended blockchain The location information of the first data, and the second data after the first data is errata; the copy block generation module 720 is used to generate the corresponding data errata based on the...

Abstract

Embodiments of the invention disclose an error correction method and system for a block chain subjected to parallel block addition, and belong to the technical field of the block chain. The method comprises the steps of receiving a data error correction request for block body data of blocks in a current formed extended block chain; according to the block body data of the first block in which first data is located, and second data in the data error correction request, generating copy blocks corresponding to current data error correction, wherein compared with the block body data of the first block, the block body data of the copy blocks has the characteristics that other data is correspondingly same except the first data is modified to the second data; and by taking any block in the extended block chain as a father block and taking the copy blocks as sub-blocks, linking the copy blocks into the block chain. According to the scheme, the error correction of block body data in original blocks is realized by adding the copy blocks in parallel into the block chain in an existing block chain extension process.

Description

Technical field [0001] The embodiment of the present invention belongs to the field of blockchain technology, and in particular relates to a method and system for correcting errors in a blockchain that adds blocks in parallel. Background technique [0002] With the continuous development of the Internet, blockchain technology emerged at the historic moment. 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 Internet dependence on central servers, so that all data changes or transaction items are It is recorded on multiple ledger nodes at the same time. Since there is no distributed peer-to-peer network with a central control point and the method of distributed collective operation is used, it can be said t...
