A method may achieve an agreement among a plurality of nodes executed by one or a plurality of processors of a blockchain system including a distributed network of the plurality of nodes. The method may comprise: receiving a candidate block in a N-th round (N is a positive integer) by an arbitrary node among the plurality of nodes able to be promoted to producer nodes having a block generation status at a predetermined time for each round, determining whether the received candidate block is a valid candidate block, determining whether the valid candidate block is an unapproved block, and determining whether to vote for approval of the unapproved block by determining whether the unapproved block is a first received candidate block which is a first received candidate block within the N-th round by the arbitrary node.
