Problems solved by technology

[0004] Generally, if there is a divergence in data uniformity in the public chain, the system will fork, and the system after the fork will split into two systems. After the split, the two systems will run independently without interfering with each other, thus forming two A "parallel time", if the fork method is used to process specific data in the alliance chain, some nodes will be separated from the entire system, so that they will not be able to participate in future data distributed bookkeeping, but this method is not desirable in the alliance chain system

Embodiment Construction

[0035] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0036] Such as Figure 1 to Figure 3 As shown, a method for repairing specified block data in the consortium chain of the present invention includes the following steps:

[0037] Step S1: suspend operation of the entire blockchain system;

[0038] Step S2: modify the configuration files of all nodes; in this embodiment, modifying the configuration files of all nodes includes: (1) modifying the startup mode, and starting all nodes in repair mode; (2) modifying the repair block data information, including the area Block height K and transaction id.

[0039] Step S3: After the message interaction of each node, each node obtains the hash of other nodes, and the whole sy...

Abstract

The invention discloses a method for repairing specified block data in an alliance chain. The whole system is suspended, data maintenance and data cleaning are carried out under the approval of all nodes, data which are not expected to exist on a chain are removed, meanwhile, the structural effectiveness of block chain data is kept, and the whole operation process is concise, effective, high in accuracy, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of block chains, and relates to a method for repairing specified block data in an alliance chain. Background technique [0002] At present, blockchain technology is widely used in various industries. Relying on the characteristics of data anonymity, decentralization, and data difficult to tamper with blockchain technology, it provides more suitable technical solutions for many application scenarios, such as in the certificate application. , digital asset transfer applications, etc. However, many applications do not need to disclose data on the entire network, and only want to limit it to some members. Therefore, in addition to the form of public chains, more enterprises or government applications choose alliance chains for implementation. Chaincode chains are only for a certain Members of specific groups and limited third parties, because all or part of their functions are only open to members, so the read ...
