(EN) METHOD FOR STORING TRANSACTION REPRESENTING ASSET TRANSFER IN DISTRIBUTED NETWORK HAVING MULTIPLE NODES, PROGRAM THEREFOR, AND NODE FOR CONFIGURING DISTRIBUTED NETWORK

PROBLEM TO BE SOLVED: To greatly improve transaction processing speed in a method for storing a transaction representing the transfer of an asset in a distributed network.

SOLUTION: A node of a first partial network that constitutes a distributed network receives a transaction generated by a user terminal, and representing the transfer of an asset from a transfer source identifier to a transfer destination identifier, and generates a block including the transaction, and executes consensus building processing in the first partial network for adoption (S303). Each node participating in consensus building stores the state of the asset of the transfer source identifier that can be processed by the node, and the transfer of the asset from transfer source identifier described in one or more transactions included in the block added after total formation is recorded (S304).

EFFECT: The transfer source identifier that can be processed in each partial network is defined, and therefore, a plurality of transaction processes can be executed simultaneously in a plurality of partial networks.

【課題】分散ネットワークに資産の移転を表すトランザクションを記憶する方法において、トランザクション処理速度を大幅に向上する。
【解決手段】ユーザー端末で生成された、資産の移転元識別子から移転先識別子への移転を表すトランザクションを、分散ネットワークを構成する第1の部分ネットワークのノードが受信し、トランザクションを含むブロックを生成して、その採択のための第1の部分ネットワークにおける合意形成処理を行う(S303)。合意形成に参加する各ノードは、各ノードが処理可能な移転元識別子の資産の状態を記憶しており、合計形成を経て追加されたブロックに含まれる1又は複数のトランザクションに記述された移転元識別子からの資産の移転を記録する(S304)。
【効果】各部分ネットワークにおいて処理可能な移転元識別子を定めることにより、複数の部分ネットワークにおいて同時に複数のトランザクション処理が実行可能になる。
