Stable currency transaction model and stable currency transaction algorithm based on digital certificate

Abstract

The invention provides a digital certificate-based stable currency transaction model, which comprises three types of participating roles, the three types of participating roles are a stable currency issuer, a virtual asset service provider and a client, the client comprises an enterprise or an individual, the stable currency issuer obtains authorized issuing of stable currency through a full-text unit, and the virtual asset service provider is a virtual asset service provider. A stable currency issuer obtains the authorized issuing digital certificate, a holder obtains the corresponding digital certificate to indicate the ownership of the digital certificate, all the transactions of the stable currency are realized through verification, generation and failure of the digital certificate on the block chain, and nodes on the block chain complete generation, verification and failure of the digital certificate. The nodes on the block chain maintain a failure certificate ID list which is used for recording the digital certificates which fail due to loss or expenditure and verifying the validity of the digital certificates at the same time; the stable currency issuer can also serve as a virtual asset service provider at the same time. The invention also discloses a corresponding transaction algorithm.

Description

technical field [0001] The invention belongs to the technical field of smart contracts, and in particular relates to a digital certificate-based stablecoin transaction model and a stablecoin transaction algorithm. Background technique [0002] On January 4, 2021, the U.S. Department of the Treasury allowed U.S. banks to issue digital stablecoins (Stablecoins) and participate in blockchain operations, and listed a series of management rules, but the U.S. Department of the Treasury did not propose a corresponding regulatory system to govern these numbers stablecoins. This is a historic event. Bank of America could not participate in the issuance of digital stablecoins before. [0003] The applicant has previously proposed the system design of digital stable currency according to the management rules, that is, the invention patent application "a dual-chain system controls stable currency issuance system", which describes that the dual-chain system realizes the issuance and man...

Problems solved by technology

But this design has serious disadvantages, because the digital currency is equal to "cash". If the digital currency is lost, the money will be lost accordingly. There have been many stories about the loss of Bitcoin digital currency in history. This is the same as the original reason for digital currency. No, because digitization should make money safer

[0005] Therefore, in order to solve this defect, this patent designs a stable currency transaction model based on digital certificates as a solution. Digital currency is just a "certificate". If the certificate is lost, the money is still there, so digital currency can solve the problem of "digital currency lost" problem
