Abstract
One or more implementations of the present specification provide an invoice access method and apparatus based on a blockchain, and an electronic device. The method includes: generating first ciphertext data by encrypting plaintext data of the target invoice based on a first key corresponding to an invoice issuer; generating second ciphertext data by encrypting the plaintext data of the target invoice based on a second key corresponding to an invoice receiver; adding the first ciphertext data and an user identifier of the invoice issuer to the blockchain as related to one another; and adding the second ciphertext data and an user identifier of the invoice receiver to the blockchain as related to one another.
