Problems solved by technology

[0003] In the existing technology, the Raft algorithm is a commonly used consensus algorithm. During the execution of the algorithm, the transaction message will be signed and verified. However, only verifying the signature of the message cannot effectively prevent non-alliance members from participating in the message consensus, thereby reducing the Security of Message Consensus

Abstract

The embodiment of the invention discloses an alliance chain consensus method, which comprises the following steps that: a master node obtains a transaction message sent by a first slave node, and carries out first message verification on a message signature and a message authority carried by the transaction message; When the verification is successful, the master node broadcasts the transaction message to the second slave node; The second slave node obtains the transaction message and performs first signature verification on the transaction message; When the verification result of the first signature verification is successful, the second slave node returns the first verification result to the master node; The master node receives the first verification result, confirms the transaction message according to the first verification result, updates the state of the transaction message, and then returns the confirmation message to the second slave node; And the second slave node obtains theconfirmation message and updates the message state of the transaction message. The message signature and the message authority of the transaction message are verified at the same time, so that the nodes participating in message consensus are all members in an alliance, and the security of the message consensus can be improved.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to an alliance chain consensus method and system. Background technique [0002] With the development of blockchain technology, more and more individuals and enterprises have begun to pay attention to blockchain. Blockchain is divided into public chain and private chain. A blockchain between the two has also become an alliance. The data consistency problem in the consortium chain is a hotspot in the development of consortium chain technology. The so-called data consistency problem is to ensure the consistency of the distributed system, that is, to ensure that the data in the distributed system is consistent. In a distributed database system, if the initial state of each node is consistent, and each node performs the same sequence of operations, then they can finally get a consistent state. In order to ensure that each node executes the same sequence of commands, a "con...
