Cross-Referencing Method for Scalable Public Blockchain

We previously proposed a cross-referencing method for enabling multiple peer-to-peer network domains to manage their own public blockchains and periodically exchanging the state of latest fixed block in blockchain with hysteresis signatures among all via an upper layer. In this study, we evaluated effectiveness our from three theoretical viewpoints: decentralization, scalability, tamper resistance. show that performance entire system can be improved because transactions blocks are distributed only inside domain. argue transaction processing capacity will increase 56,000 per second, which is as much VISA credit card system. The also by multiplying number average reduction transaction-processing time due size block-generation-time interval domain partition. For resistance, each has evidence other blockchain. introduce two types tamper-resistance-improvement ratios evaluation measures resistance theoretically explain how using method. With method, improves increases. 1,000 3-10 times more tamper-resistant than 100 domains, 10 higher. conclude enables scalable balanced decentralization.
