Method and system for jointly managing digital currency by multiple terminals and storage medium

Abstract

The invention discloses a method and system for jointly managing digital currency by multiple terminals and a storage medium. The method comprises the steps of acquiring private keys generated by a plurality of terminals, generating a plurality of first public keys, aggregating the first public keys to obtain a plurality of first aggregation public keys, determining a Merkel tree and a root of theMerkel tree according to the first aggregation public keys, and uploading the root of the Merkel tree to mark a corresponding digital currency. According to the invention, only under the condition that at least t terminals send out transaction requests, the digital currency transaction request can pass the verification of a digital currency registration center; the digital currency registration center can perform transaction on the same digital currency only when enough terminals apply for transaction on the same digital currency, the safety and atomicity of the transaction process are ensured, the implementation cost is low, and meanwhile, the digital currency registration center is prevented from being too complex. The method is widely applied to the technical field of digital currency.

Description

technical field [0001] The present invention relates to the technical field of digital currency, in particular to a method, system and storage medium for multi-terminal joint management of digital currency. Background technique [0002] Digital currency is a brand-new form of currency recognized by central banks or other currency issuers in some countries or regions. The technical framework of the existing digital currency is: the central bank sets up a digital currency registration center to generate and manage encrypted strings, which are equivalent to paper currency; users use electronic terminals to store and manage encrypted strings, which is equivalent to holding There is currency; the digital currency registration center marks the ownership of the digital currency through the public key. When the user uses the digital currency, he uses the private key generated by himself to sign the transaction. The digital currency registration center uses the number of the digital ...

AI Technical Summary

Problems solved by technology

By using smart contracts, the existing technology can be adapted to the above multi-person transaction scenario, but the application of smart contracts requires the transformation of the digital currency registration center, which will incur high costs and complicate the design of the digital currency registration center , it is difficult to guarantee the security and atomicity of the transaction process
