Abstract

The application relates to the technical field of block chains, especially to a node election method and device and storage medium that are applied to a server. The method comprises the steps that when a plurality of standby nodes are started, a timer is sent to each standby node, timing operation is conducted on the standby nodes according to the timer corresponding to each standby node, and eachtimer corresponds to the same timing period; if the plurality of timers are in the timing period and at least one standby node receives heartbeat information sent by the main node, the identity states of the plurality of standby nodes are kept; and if each timer is overtime and the plurality of standby nodes do not receive the heartbeat information sent by the main node, the main node is determined to crash, a preset election algorithm is performed, a target main node is determined from the plurality of standby nodes, and the identity states of the remaining plurality of standby nodes are kept. By adopting the node election method and device provided by the embodiment of the invention, the operation of the whole blockchain network can be maintained.

Description

technical field [0001] The present application relates to the technical field of blockchain, and specifically relates to a node election method, device and storage medium. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. A node in the blockchain can provide endorsement services to the client, including the repeatability check of the transaction ID, the generation of the transaction read-write set, and the final signature and other services; under the current master-standby synchronization architecture, the master node is mainly responsible for Obtain the block from the ordering node and perform signature verification and multi-version check on the block, while the standby node mainly provides the endorsement service to the client. Under this architecture, if the master node goes down unexpectedly, the standby node will not...
