Abstract
The blockchain generation apparatus 1 includes: a synchronizer 121 that acquires shared data 111 which includes the blockchain data 112 and transaction datasets 113 not included in the blockchain data 112; a transaction pattern count calculator 124 that calculates the number of transaction patterns for a generating party using the blockchain generation apparatus 1, based on the transaction datasets which are in the blockchain data 112 and are related to an identifier of the 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 number of transaction patterns calculated by the transaction pattern count calculator; and a blockchain generator 126 that tries to generate the new blockchain by referring to the shared data 111 if the block generation condition checker 125 determines that the generating party is qualified.
