Consortium blockchain node hot-standby switching method

Abstract

The invention discloses a consortium blockchain node hot-standby switching method. The node hot-standby switching steps are specifically as follows: a candidate node establishes connection with a consensus node; the consensus node sends network configuration thereof and consensus routing table information thereof to the candidate node in real time so as to perform standby; the candidate node performs fault detection on the consensus node and decide whether to trigger the node upgrading replacement process; the candidate node is online upgraded as the consensus node and connects with the consensus node of a block chain network according to the standby network configuration, and the own consensus state is initialized to a state in a downtime of the consensus node, thereby accomplishing the replacement. Through the method disclosed by the invention, the consensus node of the mechanism is in abnormal downtime in the consortium blockchain network composed of multiple mechanism in participation; in the premise of not importing the artificial operation, the operation of online upgrading the consensus node on the candidate node line can be automatically accomplished, on the basis of guaranteeing that the block chain network consensus efficiency cannot be affected, and the single-spot fault of the consensus node in the mechanism is avoided.

Description

technical field [0001] The invention relates to a decentralized blockchain CA certificate system, in particular to a method for hot standby switching of alliance chain nodes. Background technique [0002] With the popularization of blockchain technology, people gradually realize that it can bring advantages such as safety and reliability, simplified processes, cost savings and enhanced trust to traditional industries, and can make up for the low efficiency, high cost and high operational risk brought by multi-party collaboration. Because of its shortcomings, it is favored by enterprises that need 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 consortium blockchain, in order to prevent being affected by Byzantine behavior of other enterprise nodes, business application transacti...

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
