EOA (Externally Owned Account) refers to the account of a user who uses Ethereum, a platform that enables the development of decentralized applications, and each account is assigned an address consisting of a random string of characters for identification. People cannot know the name of the account holder from this address, and a robust control system of blockchain technology to access an account is used to ensure the confidentiality of the user.
Startbahn Cert. (This Service) is based on Startrail, a public blockchain built on Ethereum. When the users register their account on Startbahn Cert., their EOA is generated at the same time because they need to access Ethereum to issue, transfer, and receive the blockchain certificate- "Cert.”.
The address of your EOA can be found in the upper left corner of the dashboard screen after you log in.
