Problems solved by technology

However, the above three methods will have different problems and consequences. For the first one, if the discarded piece of data is important data, then losing the data will lead to catastrophic consequences, even if the discarded piece of data It is not important data, and saving some garbage data on the chain will also cause a storage burden on the chain; for the second type, if multiple transactions are managed separately, the management of the mult

Abstract

The invention discloses a block chain-oriented secret key management method and device, equipment and a storage medium. The block chain-oriented secret key management method comprises the steps: if rollback secret key data is detected, storing the rollback secret key data in a preset key value database, the rollback secret key data comprising a secret key and a key value corresponding to the secret key; acquiring key data in the key value database according to preset time; judging whether data corresponding to the key value exist on the block chain according to the obtained key value of the key data; if so, decrypting the data corresponding to the key value by using the obtained key of the key data, and judging whether the decryption is successful; and if the decryption is successful, storing the obtained key data in a preset relational database. By implementing the scheme, the data uplink transaction and the data key loss transaction can be separately processed, so that the key of thedata can be effectively prevented from being lost, and the negative effect caused by losing the data key is avoided.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a blockchain-oriented key management method, device, equipment and storage medium. Background technique [0002] In the application scenario of storing data in the blockchain system, specifically, the data stored on the blockchain needs to be encrypted and stored, and when the data on the chain is encrypted and stored, the key will be randomly generated, and the randomly generated The key is stored in a database. The existing storage schemes are to write the randomly generated key into a database for storage while writing data to the chain. However, if the data is written to the chain, there is a timeout of entering the chain or there is no return due to network reasons. Or when there is a network abnormality, the key stored in a database corresponding to the data written on the chain will be rolled back or the operation of writing the key will not be performed, which...
