This project presents a decentralized approach to copyright management, specifically focusing on the Interested Party Information (IPI) system. The IPI system uniquely identifies rights holders globally, allowing for the tracking of rights and their protection. The proposed solution involves representing rights as Non-Fungible Tokens (NFTs) on-chain, providing autonomy to rights holders in managing their NFTs, ensuring consistency and avoiding conflicts. 📜 🎨

The project is implemented on the Algorand blockchain, utilizing Algorand Standard Assets (ASAs) to represent rights as NFTs. The stateful and stateless smart contracts are used to manage the on-chain consistency of created rights. Techniques like Merkle Trees and BitMatrix are introduced to efficiently verify on-chain whether a right already exists, minimizing computational and memory overhead.
