Digital asset, server, terminal and digital asset transaction method

Abstract

The invention provides a digital asset, a server, a terminal and a digital asset transaction method. The digital asset comprises the steps of encrypting basic layer information and a version number ofa first private key through the first private key to obtain a digital signature; obtaining anti-counterfeiting layer information according to the basic layer information and the digital signature; and encrypting the anti-counterfeiting layer information through a second public key to obtain the digital asset, thereby providing a digital asset with a non-quota value, enhancing the security of thedigital asset, and improving the processing efficiency of a digital asset system while ensuring the secure circulation of the digital asset.

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
