Abstract
An electronic bill management method performed in an electronic bill management system is provided. A bill issuance request of a first user including original bill information is received. A first bill account corresponding to the first user is generated based on the original bill information, and account information of the first bill account is stored to an account table in the electronic bill management system. A second block is generated based on the bill issuance request, the first bill account, and a block header eigenvalue of a first block in a block chain in the electronic bill management system. The first block is a previous block of the second block in the block chain, and a bill issuance event of the first user is recorded based on the second block. An issuance success message is transmitted to the first user, the issuance success message including the first bill account.
