Systems and techniques for maintaining and validating vehicle ledgers using blockchain techniques are disclosed. The technique includes receiving, at a host node in a system, a request to update a vehicle ledger associated with a first vehicle node constituting the system. If the first criterion is met, the system updates the vehicle ledger, including generating an updated version of the vehicle ledger using vehicle data stored in a primary ledger associated with the primary node, and transmitting the updated version of the vehicle ledger to the first vehicle node. If the first criterion is not met, the system abandons updating the vehicle ledger. The vehicle data corresponds to a first vehicle associated with the first vehicle node. A master ledger is implemented using a blockchain containing vehicle records of vehicles associated with the system. The blockchain includes a first block including vehicle data corresponding to a first vehicle.
公开了使用区块链技术来维护和验证运载工具账本的系统和技术。该技术包括在系统中的主节点处接收更新与构成该系统的第一运载工具节点相关联的运载工具账本的请求。如果满足第一标准,则该系统更新运载工具账本,包括:使用与主节点相关联的主账本中存储的运载工具数据来生成运载工具账本的更新版本,以及将运载工具账本的更新版本传输到第一运载工具节点。如果不满足第一标准,则系统放弃更新运载工具账本。运载工具数据对应于与第一运载工具节点相关联的第一运载工具。使用包含与系统相关联的运载工具的运载工具记录的区块链来实现主账本。区块链包括包含与第一运载工具相对应的运载工具数据的第一区块。
