| Abstract(in English) | The amount of data that a node in a blockchain needs to store is increasing rapidly in proportion to the total number of transactions processed by the blockchain. As the amount of the data increases, it may be difficult to keep participating in the blockchain because of its storage capacity. If the number of nodes in a blockchain decrease, serious problems such as unstable consensus formation in the blockchain will arise. In this paper, novel reduction methods of amount of data in blockchain node are proposed. In the proposed methods, a block chain is divided into block-groups forming a block-group-chain. Each node stores only the latest blocks and block-group-chain information and some block-groups that are distributed and held. As the result, the amount of data on the node can be significantly reduced compared to the conventional methods. It is also shown that the proposed method can significantly reduce the amount of data for both full nodes and light nodes. |
