Toyota explores building "MOA" based on the account abstraction standard ERC-4337 in the Ethereum ecosystem

ChainCatcher news, Toyota Blockchain Lab published a blog post stating that it is researching how to introduce mobility into public blockchains. 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 even if the private key is lost, the account itself can be retained. This makes account management more secure and flexible. By preserving a state available for external reference, information related to vehicles (such as usage history and maintenance records) can be managed more transparently and efficiently.In addition, MOA allows operations to be executed with the approval of multiple entities (rather than a single entity). This enables various stakeholders, including vehicle users, owners, manufacturers, dealers, and regulatory agencies, to participate in the approval process for vehicle-related transactions.It is reported that the Toyota Blockchain Lab is an organization established within the Toyota Group in 2019, aimed at promoting the use of blockchain. Initially focused on corporate projects related to material and information traceability, its activities have recently expanded to include public chain-related topics such as web3 and innovative finance.
