Example Embodiment
[0042] The present invention will be described in detail below with reference to the drawings and embodiments.
[0043] figure 1 It is a flowchart of an encrypted storage method for electronic contract data provided by an embodiment of the present application.
[0044] Such as figure 1 As shown, the method of this embodiment includes:
[0045] S11: Obtain contract documents from the bottom of the blockchain;
[0046] S12: Generate the original hash value according to the contract document;
[0047] The original hash value is generated based on the contract content in the contract document, because the content of each contract document is different, so each original hash value will be different.
[0048] As an optional implementation manner of the present invention, the generating the original hash value according to the contract document includes: encrypting the contract document using the SHA-512 algorithm to generate the original hash value.
[0049] SHA (Secure Hash Algorithm, translat...
