According to the intellectual property information from Tianyancha, on June 26, 2024, Shenzhen Qianhai WeBank Co., Ltd. applied for a patent titled “A transaction verification method, device, and storage medium”, with publication number CN202410379695.2 and application date of March 2024.
The patent abstract shows that the disclosed embodiment in this application provides a transaction verification method, device, and storage medium related to the field of blockchain technology. In this method, the blockchain system receives a transaction to be verified from the client, which carries the transaction address. The transaction to be verified includes transaction content, target signature, and signature random number. Based on the signature random number and the coordinates of the known base point, the verification parameters are generated. The encryption public key is recovered based on the verification parameters and the target signature. The target signature is verified based on the encryption public key and the transaction content. When the signature verification is passed, the encryption public key is encoded to obtain the reference address. If the reference address matches the transaction address, the transaction to be verified is determined to be valid. Compared to transmitting and storing the encryption public key, this application transmits and stores the signature random number, which reduces the occupation of transmission and storage resources and improves the efficiency and performance of the blockchain system.
