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.

Block generation method in blockchain-based system

Provided is a method comprising acquiring information on a branch formed on blockchain data, calculating a difference in a block height between a target block corresponding to a current block height of the blockchain data and a block in a non-branched state based on the information on the branch and calculating a transaction confirmation reliability of transaction data recorded in the target block based on the difference in the block height, wherein the transaction confirmation reliability indicates a probability that, for as k blocks are further connected after the target block, a position of the block at which the transaction data is recorded will not change, wherein k is an integer greater than zero.
