A method for establishing agreement between nodes in a Blockchain network and a Blockchain system

摘要

The embodiment is a method for achieving consensus among the plurality of nodes on a blockchain composed of a distributed network of a plurality of nodes, and the plurality of nodes capable of being promoted to a producer node having a block generation status at a predetermined time point for each round. A first node of any one of the nodes receiving a candidate block in the Nth round; Determining whether the received candidate block is a valid candidate block; Determining whether the valid candidate block is an unauthorized block; And determining whether the non-approved block is the first received candidate block and determining whether to approve or reject the non-approved block, wherein the first received candidate block is a candidate first received by the first node within the Nth round. It is possible to provide a method for achieving consensus among the plurality of nodes on a blockchain composed of a distributed network of a plurality of nodes that are blocks.
