| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Blockchain is the fundamental system of bitcoin running on non-structured P2P networks. This con- struct a practical distributed consensus system with fault tolerance and sustainability by all participating nodes having the same transaction ledger and using an distributed consensus algorithm called PoW, do calculation work called mining. However, scalability problem is becoming serious due to the nature of the blockchain. As the data size of the ledger increases, the storage load of all the participating nodes increases. This causes the low performance node to loave, and there is possibility that fraud risk increases, because most of the system components of having blockchain and mining concentrate on the company and community nodes. In order to solve these problems, in this paper, we propose a method to decentralize having nodes and mining nodes by clustering the nodes that have blockchain data and the nodes that do PoW work. As a result, we con rm that the performance in the blockchain data size possessed by each node improves. |
