METHOD AND DEVICE FOR DYNAMICALLY ADDING CONSENSUS NODE IN BLOCKCHAIN

摘要

The present application relates to a method and device for dynamically adding a consensus node in a blockchain. The method comprises: receiving a registration request, initiated by a new participant, for registration as a new consensus node in a consensus network, wherein the registration request is used for initiating registration to the consensus network; generating, according to the registration request, a network update block in which topological information of a new consensus network is written, wherein the new consensus network comprises consensus nodes and the new consensus node in the consensus network; and synchronizing block information in the consensus network and the network update block to the participant and the consensus nodes to obtain the new consensus network. In the present application, the problems of a very large amount of calculation for locally replaying a transaction and low performance caused by state machine replication due to the fact that a node newly added into a consensus network performs data synchronization of a ledger block by means of state machine replication are solved. Moreover, there is no need to replay a transaction, such that the amount of calculation of each consensus node during synchronization can be effectively reduced, thereby improving the synchronization efficiency.
