WEMIX3.0 blockchain has External Owned Accounts (EOA) and Contact Accounts (CA).


EOA is simply a user account. A private key is generated through a wallet, and a public key is generated through a private key using the ECDSA algorithm. The EOA is authorized by the private key that the user has.


CA is authorized by the contract code. Therefore, the CA does not have a private key. An electronic signature is required to generate a transaction and is signed with a private key. EOA has a private key, so it can generate transactions, but CA cannot create transactions on its own. The CA can only perform internal transactions at the request of another account.
