摘要

The blockchain generation apparatus 1 comprising: a parameter calculator 122 that identifies a parameter type to be used for linkage of the new block, based on block approval method data 114, and calculates a value for the identified parameter type based on transaction datasets which are related to an identifier of a generating party; a block generation condition checker 125 that determines whether the generating party is qualified to generate the new blockchain data, based on the value calculated by the parameter calculator 122; and a blockchain generator 126 that tries to generate the new blockchain by referring to the shared data when the block generation condition checker 125 determines that the generating party is qualified. An identifier of the blend pattern included in the block approval method data 114 specifies a combination of the plurality of parameter types that conflict with each other.
