Design of Extensible Non-Fungible Token Model in Hyperledger Fabric
Sangwon Hong, Yoongdoo Noh, Chanik Park · 2019
This paper presents an extensible non-fungible token (NFT) model for supporting NFTs in Hyperledger Fabric (Fabric) with reference to ERC-721 defined as Ethereum standard NFT and Cosmos NFT. In this model, we defined the standard structure and interface for all Fabric NFTs. This model also supports the extensible structure and interface that accommodates different types of NFTs. To demonstrate how to take advantage of this model, we applied extensible NFTs such as document and signature tokens to a decentralized signature service.
