Blockchain ledger validation and service

A method for maintaining vehicle ledgers in a distributed network architecture, the method comprising:

• receiving, at a master node in the distributed network architecture, a request to update a vehicle ledger associated with a first vehicle node of a plurality of vehicle nodes comprising the distributed network architecture;
• in accordance with a determination that first criteria are met, updating the vehicle ledger, including:
• generating an updated version of the vehicle ledger using vehicle data stored in a master ledger associated with the master node, wherein the vehicle data corresponds to a first vehicle associated with the first vehicle node, and wherein the master ledger is implemented using a blockchain that contains vehicle records for a plurality of vehicles associated with the distributed network architecture, the blockchain including a first block including the vehicle data corresponding to the first vehicle,
• transmitting the updated version of the vehicle ledger to the first vehicle node, and
• causing the first vehicle node to update a memory location in the first vehicle node corresponding to the vehicle ledger in the first vehicle node by replacing a current version of the vehicle ledger with the updated version of the vehicle ledger in the memory location of the first vehicle node;
• and
• in accordance with a determination that the first criteria are not met, forgoing updating the vehicle ledger.

A non-transitory computer-readable storage medium storing one or more programs configured to be executed by one or more processors, the one or more programs including instructions for:

• receiving, at a master node in a distributed network architecture, a request to update a vehicle ledger associated with a first vehicle node of a plurality of vehicle nodes comprising the distributed network architecture;
