Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0031] As mentioned above, during any consensus process between nodes in the blockchain, the server participating in this consensus in any node may experience abnormal phenomena such as going offline or restarting, resulting in the server being unable to continue to participate in the consensus, thus having It may reduce the success rate of consensus,...

Abstract

The embodiment of the application discloses a consensus method and device based on a block chain. One block chain node includes a first server, a second server and at least one database. The method includes: storing consensus data, which is required for executing consensus, by the database to enable the first server and the second server to invoke the same in a process of executing the consensus; when abnormity of the first server appears before executing the consensus or in the process of executing the consensus, replacing the first server by the second server to acquire the consensus data from the database, execute the consensus according to the consensus data, and generate a consensus result; and storing the consensus result in the database by the second server. By utilizing the embodiment of the application, the normal server in the node can take over the abnormal server to acquire the consensus data from the database and execute the consensus, thus normal performing of the consensus is guaranteed, a success rate of the consensus process can be increased to a certain extent, and then the service processing efficiency of the block chain can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a blockchain-based consensus method and device. Background technique [0002] At present, blockchain technology has been widely used, and its decentralized model ensures that data is not easy to be tampered with, thus improving security. [0003] In the actual application scenario, the blockchain can provide corresponding business services for the client, and the blockchain nodes can process the user's business requests and generate corresponding processing results. However, the blockchain may contain malicious nodes or faulty nodes, which will undoubtedly affect the business services obtained by the client. To this end, a consensus process such as Practical Byzantine Fault Tolerance (PBFT) can be carried out among the nodes in the blockchain, so that each node can jointly approve the correct processing result. [0004] Taking the PBFT-based consensus process as an ...
