Abstract

The embodiment of the present application discloses a certificate storage processing method, device, equipment and storage medium, which relates to blockchain technology and can be applied to cloud computing and cloud services. Wherein, the method includes: receiving a data deposit transaction request, wherein the data deposit transaction request is based on the deposit data, the pre-acquired credible time stamp of the deposit data, and the time stamp providing the credible time stamp. The digital signature of the provider is initiated, and the trusted timestamp is obtained by the timestamp provider from the timestamp server selected by the deposit requester; if the verified digital signature matches the deposit data, the credible timestamp of the deposit data is determined It is valid and executes the data deposit transaction request, and stores the deposit data and the credible timestamp of the deposit data to the blockchain network. The embodiment of the present application can solve the problem of low efficiency of certificate storage processing in the existing certificate storage scheme, and improve the efficiency of data certificate storage processing.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to blockchain technology, and in particular to a method, device, device and storage medium for depositing certificates. Background technique [0002] Blockchain data storage refers to storing data on the blockchain to achieve the purpose of anti-tampering, traceability and trustworthy data sources. In order to further strengthen the authenticity and authority of the deposit data, the deposit service provider usually cooperates with the trusted timestamp service provider, that is, the trusted timestamp service provider adds a trusted timestamp to the deposit data. [0003] In the existing scheme, the depository service provider usually stores the deposit data on the chain first, and then requests the credible timestamp corresponding to the deposit data from the credible timestamp service provider, and finally combines the credible timestamp with After the storage certifi...
