NFTs & IP 3: Haɗa ERC721 & ERC20
Mai wakiltar tushen IP tare da ERC721 da lasisin IP na fungible tare da ERC20, don haɗa fa'idodin duka biyun.
The goal of this series is to practically connect NFTs with Intellectual Property (IP) to help NFT creators and collectors. It uses the language of IP and focuses on Solidity code-level implementations.
Article 1 of this series focused on the ERC721 non-fungible token standard, and article 2 on ERC20 fungible token standard. This article links ERC721 & ERC20, and describes how combining them gets benefits of both.
There are two big-picture scenarios on how base IP and sub-licenses relate.
Just base IP. This is quite simple. It’s a single artifact and there are no sub-licenses. For example, an artist paints a painting and has a copyright of it. That painting is sold to a collector who then gets exclusive rights to it. The base IP started as copyright held by the painter, then was transferred to the collector.
Sub-licenses against the base IP. This has many varieties. Typically the sub-licenses are fungible. For example, an author writes a book and has copyright of it; he does an exclusive license of this base IP to a publishing house. The house sells 10,000 physical books, each having its own fungible sub-license against the base IP. As a second revenue stream, it might also sell 20,000 e-books, each having its own fungible sub-license (a different license compared to the physical books).
