According to the official website of Toyota Blockchain Lab, Toyota is exploring new possibilities of blockchain and mobility from a technical perspective, saying that the purpose of developing the "Mobility Oriented Account" (MOA) tool using the ERC-4337 standard is to move towards fully autonomous driving in the future. In the future, users will be able to submit the address and rights represented by NFTs to MOA-IVD using smartphone applications, etc., and perform hardware operations such as unlocking keys on the car. These NFTs are recorded on the blockchain, and the hardware operations of the car are realized through the interaction between users, cars and blockchain, which means that flexible digital rights can be exercised for mobile hardware operations.
