And the block chain node responds to the identity authentication transaction request of the authenticator and obtains the authentication data which is uploaded by the authenticator and is about the target user. Authentication data refers to data relating to a target user issued by an authenticator and may indicate the identity of the authenticator. For example, the authenticator is a college, the target user is a student of the college, the content of the authentication data is the school achievement of the target user issued by the college, and the name of the college is indicated in the authentication data. The authentication data obtained by the blockchain node is authenticated data, that is, the authentication data is determined to be data sent by the authenticator. For example, the authenticator may encrypt the authentication data with a key, and if the authentication data can be decrypted with the key of the authenticator, the authentication data is authenticated data. The authenticator may also sign the authentication data, and if the signature matches the correct signature of the authenticator, the authentication data is authenticated data, and the identity of the authenticator may be determined by the signature.
