Design And Implementation Of Digital Asset Management Platform Based On NFT

Cultural and creative industries have developed rapidly with the vigorous support of the state.With the rising of the digital economic entities represented by Internet companies,it makes the dissemination of digital content faster,the creation forms more abundant and colorful,and the communication channels more diversified.However,the great challenges have been brought by the openness and sharing characteristics of the Internet to the copyright protection and trading of digital assets.The three major problems exist in the traditional digital asset management mode.The first problem is the poor security performance of data storage.By storing the data assets in the centralized server,there are risks of data leakage and tampering.The second problem is the copy of digital content in unlimited quantities.Due to the cumbersome confirmation of assets,the phenomenon of piracy and infringement exists in the process of transaction.The third problem is that users are not sensitive to the ownership of digital assets.Due to the lack of the effective operation mechanism in the operation of digital assets,the deep value of digital assets cannot be played under the low circulation rate.The bottom layer of NFT relies on blockchain and smart contract technology to enable the existence of digital assets in an open form not needing trust.By combining digital asset management with NFT,the key research is carried out in this thesis.The bottom layer of NFT relies on blockchain and smart contract technology to enable the existence of digital assets in an open form without trust.By combining digital asset management with NFT,the key research is carried out in this thesis.Considering the urgent requirement for rapid confirmation,copyright and circulation of digital assets on the Internet,a digital asset management platform based on NFT,oriented to digital assets,using the IPFS distributed file system,and the link of smart contracts is designed and implemented in this thesis.The following is the research work of this thesis:(1)A digital asset storage solution based on the IPFS distributed file system is designed.The IPFS file system can adopt the SHA-256 algorithm to generate the unique identification of digitization for digital assets to ensure that data cannot be tampered with.The IPFS file cluster system is built to solve the problem of single-node data loss,so as to ensure the security,reliability and availability of data storage.(2)An NFT digital asset issuance scheme based on ERC-721 standard smart contracts is designed.The smart contracts are deployed to the Ethereum testnets,the contract execution is triggered through transaction messages,so the functions such as NFT creation,transfer,purchase,destruction and so on can be completed.(3)The digital asset storage scheme and the digital asset issuance scheme are combined to design a digital asset management platform,it designed the overall function and technical architecture of the digital asset management platform,a new digital asset issuance method is provided for cultural and creative teams and individuals,the use right and ownership of digital assets are managed through blockchain bookkeeping,and the digital assets can be collected,used,shared and transferred like physical assets.(4)The introduction to the background of the animation production team on the CGYUN platform is made.On the digital asset management platform,the production team publishes the copyright and IP-derived content of digital cultural and creative projects as NFT.The function of each module testing and expected results are basically identical,The normal operation of each functional module of this platform can provide stability service for digital assetization.The blockchain and smart contract technology are applied to CGNFT digital asset management,the circulation and copyright problems in traditional asset management systems are solved,the proof of rights for digital assets in the real world is provided,the transparency and security of asset information are enhanced,the regulation on the digital cultural and creative copyright protection is made,the mutual integration and circulation of physical assets and virtual assets can be effectively promoted,and the vitality of the digital content market can be stimulated.
