1. A blockchain generation apparatus that includes a processor and storage and that generates new blockchain data by linking a new block to blockchain data which is a chain of a plurality of blocks each including transactional datasets generated by a plurality of transaction generation apparatuses, the blockchain generation apparatus comprising:
a synchronizer, that uses the processor, and that acquires shared data which includes the blockchain data and transaction datasets not included in the blockchain data;
a parameter calculator, that uses the processor, and that
identifies a parameter type to be used for linkage of the new block based on a blend pattern that defines a repeating pattern of blocks of a first parameter type and blocks of a second parameter type, and based on parameter types of a plurality of blocks in the blockchain data, wherein the plurality of blocks in the blockchain data includes at least two repetitions where a first repetition includes a first block of the first parameter type followed by a second block of the second parameter type, and a second repetition includes a subsequent second block of the second parameter type followed by a subsequent first block of the first parameter type, wherein each of the parameter types specifies a block approval method data, and
calculate a value for the identified parameter type based on transaction datasets which are among the transaction datasets and are related to an identifier of a generating party using the blockchain generation apparatus, wherein when the identified parameter type is number of coins saved, the value is based on a number of coins saved by the generating party;
a block generation condition checker, that uses the processor, and that determines whether the generating party is qualified to generate the new block, based on the calculated value for the identified parameter type; and
a blockchain generator, that uses the processor, and that generates the new block when the block generation condition checker determines that the generating party is qualified, wherein the new block includes an identifier of the parameter type used to generate the new block,
wherein the block approval method data in the storage specifies the blend pattern, and fulfilling requirements of the first parameter type prevents fulfilling requirements of the second parameter type, and
wherein the block approval method data specifies the blend pattern in which the first parameter type is repeated a first number of times and thereafter the second parameter type which conflicts with the first parameter type is repeated a second number of times.
