According to ChainCatcher, Toyota Blockchain Lab published a blog post saying 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 preserved 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 the car (such as usage history and maintenance records) can be managed more transparently and efficiently.
In addition, MOA allows operations to be performed with the approval of multiple entities rather than just one. This enables a variety of stakeholders, including car users, car owners, manufacturers, dealers, and administrative agencies, to participate in the approval process for car-related transactions.
It is reported that Toyota Blockchain Lab is an organization established within the Toyota Group in 2019 to promote the use of blockchain. The initial focus was on corporate projects for material and information traceability. In recent years, it has expanded its activities to include public chain-related topics such as web3 and innovative finance.
