Abstract

In recent years, Bitcoin has been distributed all over the world. The Bitcoin blockchain has a mechanism to generate blocks once every 10 minutes, but in reality, the block generation time changes significantly due to changes in mining power. Therefore, there is concern that the number of transactions and transaction completion time will not be stable. In this research, we propose a method to stabilize the block generation time by adjusting the difficulty of mining by changing the mining power. As a result, we think that it is effective when the mining power changes significantly in an actual blockchain network.
