This paper presents a novel method for minting hierarchical Non-Fungible Tokens(NFTs) via a parent-child structure. In contrast to existing NFT structures, our proposed model enables an NFT to act as a parent, creating child NFTs and distributing ownership stakes among them. These child NFTs are recursively structured, allowing them to generate their own descendants. The existing structure of NFTs does not inherently allow for fractional ownership. However, our proposed hierarchical model provides a feasible solution to this restriction. By dividing an NFT into multiple child NFTs, each with its own unique identity, we facilitate the detailed division of an asset, thereby making fractional ownership possible. In conclusion, the hierarchical NFT model proposed in this paper offers a promising solution to the challenges of fractional ownership in the digital asset arena. By enabling the detailed division of NFTs through a parent-child structure, we anticipate a future where digital assets can be owned and traded more flexibly and transparently.
