Block chain-based digital asset processing method

Abstract

The invention relates to digital asset processing, in particular to a block chain-based digital asset processing method, which comprises the following steps of receiving an uplink request of a user, carrying out dimension reduction processing on digital assets sent by the user, calling a private key to which the user belongs according to the uplink request to encrypt the dimension-reduced digital assets and generate a signature; acquiring an uploading timestamp and an expiration timestamp of the dimension-reduced digital assets, generating a transaction tag with a deadline attribute, uploading the transaction tag and the dimension-reduced digital assets to a block chain, receiving a transaction request of a user, calling the dimension-reduced digital assets to be transacted and a corresponding signature according to the transaction request, verifying the signature, verifying identity information of the transaction proposing terminal according to the transaction request, and verifying a result and an identity verification result according to the signature; the technical scheme provided by the invention can effectively overcome the defects that whether the digital assets are tampered by the owner is difficult to verify and the storage condition and the transaction state of the digital assets cannot be completely recorded in the prior art.

Description

technical field [0001] The invention relates to digital asset processing, in particular to a blockchain-based digital asset processing method. Background technique [0002] Blockchain technology (Block Chain) refers to a technical solution for collectively maintaining a reliable database in a decentralized manner. This technical solution mainly allows blocks to be associated through cryptographic methods. Each block contains a certain amount of time All data information in the internal system, and generate a digital signature to verify the validity of the information, and link to the next data block to form a main chain. Among them, a block is a record in the blockchain that contains and confirms pending transactions. [0003] Digital assets refer to non-monetary assets owned or controlled by enterprises or individuals that exist in the form of electronic data, are held in daily activities, are ready for sale or are in the process of production. With the development of com...
