Embodiment Construction
[0049] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0050] Blockchain is a continuously growing list of records (blocks, blocks). These lists are connected in series through cryptographic methods, and have the characteristics of non-alterable, open, and transparent. For the real data generated in the physical world, the nodes in the blockchain can construct it into a standard transaction format supported by the blockchain, and then publish it to the blockchain, and the nodes in the blockchain will process the received transactions Consensus processing, and after a consensus is reached and confirmed, the accounting node in t...

The invention is suitable for the technical field of block chains, and provides a block chain-based evidence storage verification method and device, computer equipment and a medium, and the method comprises the steps: obtaining evidence storage uplink data according to a to-be-verified evidence storage file; determining associated summary information of the evidence storage uplink data according to the to-be-verified summary information in the to-be-verified evidence storage file; carrying out abstract verification on the to-be-verified evidence storage file according to the to-be-verified abstract information and the associated abstract information, and if the abstract verification is qualified, carrying out signature verification and timestamp verification on the evidence storage uplink data; and if the signature verification is qualified and the timestamp verification is qualified, determining that the to-be-verified evidence storage file is qualified, and generating an evidence storage verification report. According to the method and the device, abstract verification is carried out on the to-be-verified evidence storage file, and the to-be-verified evidence storage file is further verified to be not tampered after being uplink based on signature verification and timestamp verification under the condition that the to-be-verified evidence storage file is not tampered, so that the accuracy of evidence storage verification is improved.
Description
technical field [0001] The present application relates to the technical field of blockchain, and in particular to a method, device, computer equipment and medium for deposit verification based on blockchain. Background technique [0002] The use of blockchain for electronic document storage has become a common solution for many manufacturers. Utilizing the non-tamperability of the blockchain, under normal circumstances, the collaborative work on and off the chain is adopted, and the file and the hash value of the file are separated. The data on the blockchain chain only saves the hash value of the file, and the original file is stored in the chain. Down. As long as the hash value of the file is calculated and compared with the hash value on the chain, a verification report corresponding to the certificate can be generated. [0003] In the existing certificate verification process, the certificate file is only verified based on the hash value, and the accuracy of verifying ...
