Abstract(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 nodeshaving the same transaction ledger and using an distributed consensus algorithm called PoW, do calculation workcalled mining. However, scalability problem is becoming serious due to the nature of the blockchain. As the datasize of the ledger increases, the storage load of all the participating nodes increases. This causes the low performancenode to loave, and there is possibility that fraud risk increases, because most of the system components of havingblockchain and mining concentrate on the company and community nodes. In order to solve these problems, inthis paper, we propose a method to decentralize having nodes and mining nodes by clustering the nodes that haveblockchain data and the nodes that do PoW work. As a result, we conrm that the performance in the blockchaindata size possessed by each node improves. |
