Improving transaction throughput is an important challenge for Bitcoin. However, shortening the block generation interval or increasing the block size makes sharing blocks within the network slower and increases the number of orphan blocks. Therefore, to mitigate this, it is necessary to reduce the block propagation delay. Because of the contribution of compact block relay and evolution of the Internet, the block propagation delay has been shortened in recent years. However, there is no quantitative analysis of these contributions. In this study, we measure the block propagation delay on the Bitcoin network using a simulator, and investigate the effect of compact block relay and Internet improvements from 2015 to 2019. The experimental results reveal that the block propagation delay is reduced by 64.5% for the 50th percentile and 63.7% for the 90th percentile due to Internet improvements, and by 90.1% for the 50th percentile and by 87.6% for the 90th percentile due to compact block relay. |
