The invention discloses a method for retrieving a key of a blockchain system. The method comprises the following steps: 1, creating an original key pair; 2, calculating a service key pair according to the original key pair; 3, calculating an address and an account according to the service key pair; 4, when the service key is lost, executing the step 2 to retrieve the service key. According to the invention, the original key pair is created, and the functional areas of the original key pair and the service key pair are separated, so that the service private key is used for the delivery, editing, approval, signature and the like of daily electronic files such as electronic judicial documents or the creation, accounting, transaction, circulation and the like of digital assets, and the original private key is properly stored in a safe place. Once the service private key is lost or damaged, the original private key can be used for recalculation to restore or retrieve the service private key. The method is not only suitable for evidence-storage type, trace-leaving type, traceability type and other blockchain systems, but also suitable for accounting type, transaction type, stream transformation type and other blockchain systems of digital assets.
Description
technical field [0001] The invention relates to the field of block chain systems, in particular to a method for retrieving keys of the block chain system. Background technique [0002] Blockchain is a term in the field of information technology. In essence, it is a distributed database or distributed ledger. The data or information stored in it has the characteristics of time sequence, immutability, traceability, openness and transparency, and collective maintenance. Based on these characteristics, blockchain technology has laid a solid foundation of trust, created a reliable collaboration mechanism, and has broad application prospects. [0003] The operation of information or digital assets on the blockchain is inseparable from the private key. The current blockchain system has functions and only has business key pairs. Users can access electronic files in the blockchain system through business key pairs (such as electronic judicial documents) or digital assets and other ...
