A method for hot standby switching of alliance chain nodes

Abstract

Disclosed is a consortium blockchain node hot-standby switching method. The steps of node hot-standby switching are specifically: a candidate node establishing a connection with a consensus node; said consensus node sending in real time network configuration thereof and consensus routing table information thereof to the candidate node for backup; the candidate node performing fault detection on said consensus node, and determining whether to trigger a node upgrade replacement process; and the candidate node being online upgraded to a consensus node, connecting a consensus node of a blockchain network according to the network configuration of the backup, and initializing a consensus state thereof to a state when said consensus node is down, so as to complete replacement. In a consortium blockchain network formed by a plurality of mechanisms, if a consensus node of a mechanism is abnormally down, and given that no manual operation is introduced, this method automatically completes online upgrading of a candidate node to a consensus node, ensuring that on the basis of not affecting the consensus efficiency of the blockchain network, the occurrence of a single node fault to the consensus node in the mechanism is avoided.

Description

Technical field [0001] The invention relates to a decentralized blockchain CA certificate system, and in particular to a method for hot standby switching of alliance chain nodes. Background technique [0002] With the popularization of blockchain technology, people have gradually realized that it can bring advantages such as safety and reliability, simplified processes, cost savings, and enhanced trust to traditional industries, which can compensate for the low efficiency, high cost, and high operational risk caused by multi-party collaboration. Disadvantages, so it is favored by enterprises that require multi-party peer-to-peer cooperation. Since multi-party collaboration often requires strict identity authentication and special access and access authorization mechanisms, the alliance blockchain has also become their main choice. [0003] In the alliance blockchain, in order to prevent the Byzantine behavior of other enterprise nodes, business application transactions developed b...

Problems solved by technology

[0006] Both of the above two methods have certain shortcomings. The first method may cause node services to be unrecoverable for a long time due to the introduction of manual operations, which is extremely unfavorable for smart contract applications that communicate with each other.

In addition, if the amount of data in the entire network is extremely large, the time spent on node data synchronization is difficult to estimate, which will cause the node to be temporarily unavailable

Although the second method has the advantage of fast recovery, in order to ensure the fairness of consensus voting among enterprises, all participating enterprises must deploy the same number of consensus nodes, and the increase in the number of consensus nodes will have a great impact on consensus efficiency
