  Abstract

The block propagation protocol between nodes in the Bitcoin network mainly operates using the Compact Block Relay (CBR) protocol. The CBR is a block compression technology that reduces network bandwidth consumption and block delivery time by transmitting only the transaction ID included in the block. However, after the introduction of the CBR, there are no experimental and analysis results showing an accurate performance. Also, there is still a delay in block propagation. Therefore, this paper shows the performance of the CBR by measuring the high-bandwidth CBR’s block delivery time between directly connected bitcoin nodes, and analyzes the cause of the delivery delay. Factors to be used for delay cause analysis are network, transaction request, chain connection and system memory amount, block size and number of transactions. The results of this paper provide analysis results of delay causes of CBR from various viewpoints. In addition, it provides an in-depth analysis of the transaction request, which is the main cause of delay. And the performance of the CBR can be improved by solving the cause of the delivery delay and discussing how to reduce the delay time through the analysis result.
