Patent number: 11429983Abstract: A target transaction to write off a target e-bill is received. In response to the target transaction, a write-off logic declared in a smart contract published on a blockchain is invoked. A bill number of the target e-bill is obtained, and whether the bill number matches an e-bill number segment maintained in a blockchain account corresponding to a bill issuer of the target e-bill is checked. In response to determining that the bill number matches the e-bill number segment maintained in the blockchain account corresponding to the bill issuer of the target e-bill, a validity check is performed on bill content of the target e-bill. After the validity check succeeds, generating a write-off completion event corresponding to the target e-bill is generated and published to the blockchain for storage.Type: GrantFiled: June 28, 2021Date of Patent: August 30, 2022Assignee: Advanced New Technologies Co., Ltd.Inventors: Xueqing Yang, Longsheng Qing, Zhen Sun, Ge Jin, Zhenzhong Meng, Yu Chu

Patent number: 11210660Abstract: A computer-implemented method, non-transitory, computer-readable medium, and computer-implemented system is provided for obtaining a real-name electronic bill. In response to an association operation initiated by a user for a target electronic bill, an association transaction is published that includes an identifier of the target electronic bill, where the association transaction causes a network node on the blockchain to return identity association prompt information when determining that the target electronic bill stored in the blockchain is not associated with user identity information (UII). The UII is collected when receiving the identity association prompt information. The UII is sent to the network node, where the network node verifies whether the UII matches identity information of a payment user in the target electronic bill, and after verification succeeds, publishes an association relationship between the UII and the identifier of the target electronic bill to the blockchain for storage.Type: GrantFiled: March 19, 2021Date of Patent: December 28, 2021Assignee: Advanced New Technologies Co., Ltd.Inventors: Zhenyu Yang, Longsheng Qing, Ge Jin, Zhen Sun, Xueqing Yang, Zhenzhong Meng, Yu Chu
