Blockchain-based invoice creation method apparatus, and electronic device

Abstract

Computer-implemented methods, non-transitory, computer-readable media, and computer-implemented systems for creating blockchain-based invoices are provided. In a computer-implemented method, an invoice creation transaction for a target payment order is received by a node device in a tax blockchain. The invoice creation transaction includes an identifier of a first collection confirmation transaction whose certificate has been stored in the tax blockchain. The first collection confirmation transaction includes an identifier of a second collection confirmation transaction whose certificate has been stored in a payment blockchain. The first and second collection confirmation transaction are identified based on the identifiers of the first and second collection confirmation transaction, respectively. In response to detecting that collection confirmation data in the first collection confirmation transaction matches collection confirmation data in the second collection confirmation transaction, invoice creation logic declared in a predetermined smart contract is invoked to create an invoice for the target payment order.
