| Abstract(in English) | Since Bitcoin appeared, a wide variety of blockchain (BC) has been proposed. As a result, the demand for exchanging cryptocurrencies between multiple BCs has increased, and it is important for BC to have interoperability, which is the property of storing and fetching information on multiple BCs each other. Also, BC has the scalability problem of extremely slow transaction processing speed. On this background, we have considered how to solve the scalability problem by enhancing blockchain interoperability. Our previous research has proposed a chainless multi-layer consensus using a cross-referencing method. But, there is a problem with communication congestion in the process of sharing blocks. In this paper, we report how to solve this problem by improving our consensusprotocol. We also conducted experiments using our node program to evaluate consensus latency time. As a result of the experiments by constructing a large-scale network with more than 100 nodes, we confirmed that the latency time increases superlinearly when the number of BCs increases to parallelize transaction processing. By using theexperimental results, it becomes possible to estimate parameter settings for a chainless multi-layer consensus safely and its transaction processing speed. |
