According to Foresight News, Toyota Blockchain Lab has announced its research into integrating mobility into public blockchains. The lab is exploring the development of Mobility-Oriented Accounts (MOA) based on the ERC-4337 account abstraction standard within the Ethereum ecosystem. This account abstraction separates the authentication process from key management, ensuring that even if private keys are lost, the account itself remains intact. This approach enhances account management by making it more secure and flexible.

By maintaining states that can be referenced externally, the system allows for more transparent and efficient management of vehicle-related information, such as usage history and maintenance records. Additionally, MOA enables operations to be executed with the approval of multiple entities rather than a single entity. This feature allows various stakeholders, including car users, owners, manufacturers, dealers, and administrative bodies, to participate in the approval process for transactions related to vehicles.
