Abstract
(EN)
Provided are a blockchain-based invoice authenticity verification method, an apparatus, and an electronic device, correspondence relationships between invoices and digital summaries of the invoices being stored in said blockchain. The method comprises: an anti-fraud verification request submitted by a client in regard to an invoice to be identified is received; in response to the anti-fraud verification request, a digital summary of the invoice to be identified is calculated, and whether a target invoice corresponding to the digital summary is stored in a blockchain is queried; and if such an invoice is stored in the blockchain, a verification result that the invoice to be identified is authentic is returned to the client.
