According to Foresight News, Toyota Blockchain Lab published a document stating that it is studying how to introduce mobility into the public blockchain and exploring the construction of MOA (Mobility Oriented Account) based on the account abstraction standard ERC-4337 in the Ethereum ecosystem.
MOA account abstraction separates the authentication process from key management, ensuring that the account itself is retained even if the private key is lost. This makes account management more secure and flexible.
By saving states that can be referenced externally, information about cars can be managed more transparently and efficiently. In addition, MOA allows actions to be performed with the approval of multiple entities, allowing various stakeholders to participate in the approval process for car-related transactions.
