Abstract
One or more implementations of the present specification provide a blockchain-based electronic bill reimbursement method, apparatus, and an electronic device. The blockchain stores electronic bills. The method includes determining whether a maintained target electronic bill is in an unreimbursed state in response to detecting a reimbursement transaction broadcasted by a reimbursement initiator for the target electronic bill to the blockchain; if the target electronic bill is in the unreimbursed state, updating the target electronic bill from the unreimbursed state to a reimbursement lock state; instructing a reimbursement acceptor to perform reimbursement processing on the target electronic bill; determining whether a reimbursement result corresponding to the target electronic bill is broadcasted by the reimbursement acceptor to the blockchain; and if the reimbursement result is detected, updating the target electronic bill from the reimbursement lock state to a reimbursed state.
