Provided is a blockchain management apparatus comprising at least one hardware processor configured to implement a block generation order control unit which prevents a block generation node of a plurality of blockchain nodes from generating a new block of a blockchain in response to a determining, by the blockchain management apparatus, that the new block is a block generated by the block generation node within a unit section, wherein the unit section corresponds to a preset number of blocks measured from a current block corresponding to a current block height of the blockchain, and the blockchain management apparatus manages a permission-based blockchain network including the plurality of blockchain nodes.

System for processing data based on blockchain and operating method thereof

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.
