Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, off-chain transactions such as Payment Channel have been attracting attention to solve the problems of low transaction throughput and high fees in blockchains. Payment Channel can relay transactions between the nodes forming the channel, which is called Payment Channel Network (PCN). However, PCN has a problem that is scalability of the number of nodes. This paper proposes a novel routing method of PCN focusing on use cases of supply chain. This method has an advantage that size of the routing table can be reduce. In addition, we have compared the proposed method with the conventional method based on the worst-case time complexity, and confirmed potential for improved scalability.
