Abstract

The invention discloses a method and a device for uploading an electronic certificate. The method comprises the steps that a front-end terminal obtains an electronic certificate, carrying out Hash processing on the electronic certificate; determining a hash value of the electronic certificate; and according to the private key of the front-end terminal, the merchant number, the terminal number andthe hash value of the electronic certificate, determining signature information, and uploading the merchant number and the terminal number of the front-end terminal, the hash value of the electronic certificate and the signature information to the blockchain node, so that the blockchain node verifies the signature information and then registers the signature information in the blockchain network.The front-end terminal directly uploads the electronic certificate to the block chain network after processing the electronic certificate, so that the problem that in the prior art, when the front-endterminal uploads the electronic certificate to the block chain through the background terminal, the electronic certificate is tampered is solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of blockchain, and in particular to a method and device for uploading electronic certificates. Background technique [0002] In the blockchain-based electronic certificate project, each acquirer hashes the electronic purchase order, stores the hash value on the distributed ledger, and other institutions obtain the hash of the electronic bill from the distributed ledger. , compared with the electronic bill to determine the authenticity and integrity of the electronic purchase order. But for non-bank acquirers, there may be cases of data falsification. Contents of the invention [0003] Embodiments of the present invention provide a method and device for uploading electronic certificates, which are used to solve the problem of falsification of information uploaded by a third-party acquirer. [0004] A method for uploading an electronic certificate provided by an embodiment of the pres...
