Server, vehicle, distributed transaction verification system, and distributed transaction verification method

A vehicle which constitutes a distributed transaction verification system comprising a server, the vehicle comprising:

• a communication circuit configured to communicate with the server which holds a blockchain in which transaction information related to an inspection of the vehicle is recorded in a chain manner;
• and
• a processor configured to control an operation comprising driving of a host vehicle,
• wherein if the host vehicle is selected as a target vehicle of an inspection,
• the communication circuit receives an execution instruction of a transaction related to the inspection, and
• the processor controls execution of the transaction related to the inspection based on the execution instruction, and controls the operation comprising the driving of the host vehicle based on an inspection result, the inspection result being based on an execution result of the transaction related to the inspection of the host vehicle and an execution result of a transaction related to the inspection of another vehicle.

A distributed transaction verification system in which a server and a plurality of vehicles are connected to communicate with each other,

• wherein the server
• holds a blockchain in which transaction information related to an inspection of each of the plurality of vehicles is recorded in a chain manner, and
• selects a target vehicle of inspection from the plurality of vehicles, creates transaction information related to an inspection of the selected target vehicle on the blockchain, and transmits an execution instruction of a transaction related to the inspection to the target vehicle,
• wherein the target vehicle executes the transaction related to the inspection based on the execution instruction, and transmits the execution instruction of the transaction related to the inspection to at least one peripheral vehicle other than the target vehicle, and
• wherein the server registers an inspection result based on an execution result of the transaction related to the inspection of each of the target vehicle and the at least one peripheral vehicle in the created transaction information related to the inspection of the target vehicle.

A distributed transaction verification method using a distributed transaction verification system in which a server and a plurality of vehicles are connected to communicate with each other, the distributed transaction verification method comprising:

• holding a blockchain in which transaction information related to an inspection of each of the plurality of vehicles is recorded in a chain manner;
• selecting a target vehicle of inspection from the plurality of vehicles;
• creating transaction information related to an inspection of the selected target vehicle on the blockchain and transmitting an execution instruction of a transaction related to the inspection to the target vehicle;
• executing the transaction related to the inspection based on the execution instruction and transmitting the execution instruction of the transaction related to the inspection to at least one peripheral vehicle other than the target vehicle;
• and
• registering an inspection result based on an execution result of the transaction related to the inspection of each of the target vehicle and the at least one peripheral vehicle in the created transaction information related to the inspection of the target vehicle.
