To provide a technique by which vehicle information provide by a vehicle is managed by multiple nodes with a decentralized ledger.SOLUTION: A ledger management node of a ledger management system comprising multiple ledger management nodes 10 connected communicatively each other where the multiple ledger management nodes comprises the same decentralized ledger comprises a decentralized ledger 24, an agreement determination unit 18, and a ledger recording unit 20. The decentralized ledger stores ledger information generated by one of the multiple ledger management nodes and including unique information unique to the previous ledger information and the current vehicle information acquired from the vehicle. The agreement determination unit determines whether ledger information that one of the multiple ledger management nodes generates satisfies an agreement rule set on the multiple ledger management node. The ledger recording unit stores the ledger information to the decentralized ledger when the agreement determination unit determines that the ledger information satisfies the agreement rule, and doe not store the ledger information to the decentralized ledger when the agreement determination unit determines that the ledger information does not satisfy the agreement rule.SELECTED DRAWING: Figure 2

    【課題】車両から提供される車両情報を複数のノードが分散台帳で管理する技術を提供する。【解決手段】互いに通信可能に接続された複数の台帳管理ノード10を備え、複数の台帳管理ノードが同じ分散台帳を備える台帳管理システムの台帳管理ノードは、分散台帳24と合意判定部18と台帳記録部20とを備えている。分散台帳は、複数の台帳管理ノードのいずれかが生成する、一つ前の台帳情報に固有の固有情報と車両から取得する今回の車両情報とを含む台帳情報を記録する。合意判定部は、複数の台帳管理ノードのいずれかが生成する台帳情報が、複数の台帳管理ノードにおいて設定された合意規則を満たしているか否かを判定する。台帳記録部は、台帳情報が合意規則を満たしていると合意判定部が判定すると、台帳情報を分散台帳に記録し、台帳情報が合意規則を満たしていないと合意判定部が判定すると、台帳情報を分散台帳に記録しない。【選択図】図2
