首先,提出了一种新的区块链链式协议,该协议允许调整挖掘过程数据的读取时间。这种策略缩小了ASIC矿机和CPU挖掘新区块速度的差距。然后通过该协议,ASIC矿机的优势将会受到限制。最后,分析了这种新区块链结构的安全性,并将其与原始区块链协议进行了安全性比较。
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.
