Abstract

One or more implementations of the present specification provide an invoice invalidation method and apparatus based on a blockchain, and an electronic device. The method includes: receiving an invalidation request that is initiated by an invoice invalidation party for a target invoice recorded in the blockchain; in response to the invalidation request, determining whether the invoice invalidation party has authority to invalidate the target invoice; and in response to that the invoice invalidation party has the authority to invalidate the target invoice, invoking an invoice invalidation logic provided in a smart contract deployed in a blockchain network of the blockchain to invalidate the target invoice.
