Digital asset, server, terminal and digital asset transaction method

Abstract

The present invention provides a digital asset, a server, a terminal, and a digital asset transaction method. The digital asset includes: using a first private key to encrypt the base layer information and the version number of the first private key to obtain a digital signature; layer information and the digital signature to obtain the anti-counterfeiting layer information; the second public key is used to encrypt the anti-counterfeiting layer information to obtain the digital asset, and the present invention can provide a digital asset with a non-fixed face value to strengthen the security of the digital asset, While ensuring the safe circulation of digital assets, improve the processing efficiency of the digital asset system.

Description

technical field [0001] The invention relates to the technical field of digital assets, in particular to a digital asset, a server, a terminal and a digital asset transaction method. Background technique [0002] The cost of physical currency manufacturing and circulation (printing, distribution, storage, transportation, destruction, banknote verification and anti-counterfeiting, etc.) is very high. With the evolution of technologies such as Internet finance, cloud computing, and blockchain, payment methods have undergone tremendous changes, and it is an inevitable trend for digital assets to replace physical currencies. In recent years, driven by blockchain technology, a variety of private encrypted digital assets have emerged in the industry, while legal digital assets are still in the research stage. [0003] The technical challenges of general digital assets mainly include: first, anti-counterfeiting. Compared with the anti-counterfeiting of physical currency through pri...

Problems solved by technology

[0003] The technical challenges of general digital assets mainly include: first, anti-counterfeiting. Compared with the anti-counterfeiting of physical currency through printing technology, digital assets use data encryption technology for anti-counterfeiting; second, "multiple payments" (digital assets are used twice or more by the owner ), compared to the circulation of physical currency through physical transfer, there is no "multiple payment" problem, and digital assets may have the problem of "multiple payment" due to the easy copying of data; the third is digital assets based on fixed face value , in the transaction process, there is a relatively high probability that the change cannot be made, and the transaction cannot be carried out. In order to reduce the probability that the change cannot be made, a large number of small-denomination currencies must be issued, which will lead to a large number of digital assets. How to deal with them efficiently The problem of concurrent transactions is more prominent
