A new blockchain chain protocol was proposed,which allowed adjusting the loading time of the mining process.This strategy reduced the ASIC and CPU mining rate of the gap,so that the using of ASIC mining is limited.Finally,the safety of this new chain structure was analyzed and compared to the original chain protocol.

Key words: blockchain, memory-hard function, multiple related protocol
