A computer-implemented method, non-transitory, computer-readable medium, and computer-implemented system is provided for obtaining a real-name electronic bill. In response to an association operation initiated by a user for a target electronic bill, an association transaction is published that includes an identifier of the target electronic bill, where the association transaction causes a network node on the blockchain to return identity association prompt information when determining that the target electronic bill stored in the blockchain is not associated with user identity information (UII). The UII is collected when receiving the identity association prompt information. The UII is sent to the network node, where the network node verifies whether the UII matches identity information of a payment user in the target electronic bill, and after verification succeeds, publishes an association relationship between the UII and the identifier of the target electronic bill to the blockchain for storage.
