Provided is a block generation method in blockchain-based system. The block generation method comprises calculating, by a first blockchain node among the plurality of blockchain nodes, a first node score, propagating, by the first blockchain node, the first node score to the plurality of blockchain nodes, receiving, by the first blockchain node, a delegation of a block generation authority from a second blockchain node among the plurality of blockchain nodes, the second blockchain node having received the first node score and initiating, by the first blockchain node, generation of a new block based on a determination that a block generation node condition, that is based on the block generation authority, has been satisfied.
