Method for storing transaction representing asset transfer in distributed network having multiple nodes, program therefor, and node for configuring the distributed network

摘要

PROBLEM TO BE SOLVED: To significantly improve transaction processing speed in a method of storing a transaction representing transfer of assets in a distributed network. A first partial network 110 constituting a distributed network receives a transaction 200 generated in a user terminal 140 and representing a transfer of an asset 203 from a transfer source identifier 201 to a transfer destination identifier 202, and the transaction 200 is received. A block including is generated, and the consensus building process in the first partial network 110 for the adoption is performed (S303). Each node stores the state of the asset of the transfer source identifier that can be processed by each node, and stores the state of the asset from the transfer source identifier described in one or more transactions included in the block added after total formation. The transfer is recorded (S304). Parallel processing of transactions is performed by defining a transfer source identifier that can be processed in each partial network. [Selection diagram] Fig. 3
