A Digital Collection Platform Architecture based on NFTs

In this digital age, the number of NFTs (Non-Fungible Tokens) in the market is growing, and NFT trading platforms are also emerging. However, most of the smart contracts used to manage the ownership, transaction and metadata information of NFT in the platform are different, that is, the management specifications for NFT are also different, which will prevent the sharing of NFT information in different platforms and affect the development of NFT. At the same time, as the number of NFT works continues to increase, when users search for NFTs, the platform needs to quickly and accurately locate the NFTs that users are interested in. Therefore, the platform needs a robust and efficient search system. We proposed a solution for the NFT platform, which manages the functions of registering NFT, searching NFT, and trading NFT of the NFT platform in the way of standardization task, search task, and verification task. The standardization task is used to unify the metadata information of NFT, resulting in the unified specification of NFT created by different users and platforms. The search task uses two methods of content addressing and elastic retrieval to realize the retrieval function of the platform and uses the verification task to learn user identity verification. Finally, the implementation algorithms of the different tools will be presented.
