Embodiment approach

[0054] In one embodiment, the received file-like digital asset is compressed to generate a compressed file, and the compressed file is used as uplink data. The file compressed by the compression software is called a compressed file. The principle of compression is to compress the binary code of the file and reduce the adjacent 0 and 1 codes. file space. The basic principle of compressing files is to find the repeated bytes in the file, and create a "dictionary" file with the same bytes, and use a code to represent it. For example, there are several places in the file that have the same word "People's Republic of China" with a The code is represented and written into the "dictionary" file, so that the purpose of reducing the file can be achieved. Common compression software are winzip, winrar and so on.

[0055] In another embodiment, a hash operation is performed on the received file-type digital asset to generate a hash value, and the hash value is used as the uplink data. ...

Abstract

The invention discloses a digital asset processing method and system based on a block chain. The method comprises steps of receiving an uploading request from a first user and uploaded file type digital assets, and enabling the file type digital assets to at least comprise one of the following file types, a patent, a certificate, a work, a document and a resume; performing data dimension reductionprocessing on the received file type digital assets to generate uplink data; and according to the uplink request, calling a private key corresponding to the first user to encrypt the uplink data to generate signature data, and uplink the signature data. Once the file type digital assets are chained, the modification difficulty of the file type digital assets is extremely high, so buyers in the file type digital asset transaction can compare the file type digital assets provided by sellers with the file type digital assets stored on the block chain to confirm whether the file type digital assets are tampered or not; and the buyer can verify reliability of the file type digital assets conveniently.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a method and system for processing digital assets based on block chains. Background technique [0002] Digital assets refer to non-monetary assets that are owned or controlled by enterprises or individuals, exist in the form of electronic data, and are held in daily activities for sale or in the process of production. Especially for file-type digital assets, the form of electronic data makes file-type digital assets easy to store, copy, and edit, which greatly facilitates the dissemination and transaction of file-type digital assets. [0003] However, due to the electronic data characteristics of file-type digital assets, file-type data assets are easily edited and tampered with maliciously during the transmission process. When the authenticity of file-type digital assets cannot be confirmed, the transaction expectations of file-type digital assets are reduced, whic...
