2. Simple Summary
A protocol facilitating the secure storage and depositing of tokenized real-world assets through authorized providers.

3. Abstract
The NFT Infrastructure Protocol (NIP) revolutionizes the NFT ecosystem by introducing a comprehensive framework for depositing tokenized real-world assets, enriching the blockchain landscape with tangible, physical value. This abstract delves into the primary innovativeness, applications, and implications of NIP, emphasizing its distinctive features in comparison to existing NFT standards.

The primary innovation of NIP lies in its ability to seamlessly integrate real-world assets into the NFT ecosystem, extending beyond the digital realm. By establishing a standardized process for depositing tokenized objects, NIP addresses the inherent challenges of representing and managing physical assets on the blockchain.

Innovative Features:

  1. Physical Asset Tokenization: NIP pioneers the secure tokenization of real-world assets, allowing owners to represent physical items as NFTs. This includes real estate, artwork, collectibles, and more.
  2. Three-Party Participation: NIP orchestrates a synchronized dance between three main participants — facility owners, NFT mint services, and depository owners. This tripartite interaction ensures a robust, transparent, and decentralized process for asset deposition.
  3. Smart Contract Synergy: Leveraging smart contracts, NIP establishes clear ownership records, facilitates secure transfers, and automates key processes such as deposit initiation, withdrawal, and ownership verification.
  4. Data Structures for Transparency: NIP introduces specialized data structures, like Asset Metadata and Ownership Records, to ensure transparent and tamper-resistant storage of critical information about tokenized assets.

Applications: NIP opens doors to a myriad of applications across industries, including but not limited to:

  • Real Estate: Tokenizing properties for efficient and transparent property transactions on the blockchain.
  • Art and Collectibles: Securing ownership and provenance of physical art pieces and collectibles as NFTs.
  • Supply Chain: Enabling the tokenization of physical goods, ensuring transparency and traceability in the supply chain.
  • Finance and Collateral: Using tokenized real-world assets as collateral in decentralized finance (DeFi) applications.


  1. Economic Inclusivity: NIP broadens the accessibility of NFTs, allowing individuals to tokenize and trade physical assets, democratizing ownership in traditionally exclusive markets.
  2. Enhanced Trust: The protocol’s emphasis on security and transparency enhances trust among participants, mitigating concerns related to ownership disputes and asset provenance.
  3. Blockchain Integration in Traditional Industries: NIP bridges the gap between blockchain technology and traditional industries by offering a standardized and secure method for integrating real-world assets into the digital realm.

In summary, the NFT Infrastructure Protocol introduces a transformative approach to tokenizing real-world assets, unlocking new possibilities for ownership, trade, and economic inclusion in the blockchain space. Its innovative features, broad applications, and positive implications position NIP as a cornerstone in the evolution of the NFT ecosystem.

4. Motivation
The NIP is crucial for the continued evolution of the NFT ecosystem by expanding its scope to include real-world assets. The motivation behind this protocol is to streamline and standardize the process of depositing tokenized objects, creating a reliable framework for participants involved. By doing so, it enhances the overall functionality of NFTs, making them applicable beyond digital art or virtual items. This protocol encourages broader adoption by establishing a secure and standardized method for integrating physical assets into the blockchain-based NFT space.

5. Rationale
The NIP addresses the current gap in the NFT ecosystem by providing a structured and secure process for depositing tokenized real-world assets. The background of the problem lies in the lack of a standardized approach for integrating physical objects into the NFT space, leading to inefficiencies, disputes, and uncertainty. The objectives of the NIP are to establish a clear framework, enhance security through authorized providers, and ensure a transparent and efficient process for all participants. The technical details include the integration of smart contracts for ownership transfers and the use of blockchain for provenance and tamper-proof records.

6. Specification (non-mandatory)
The NFT Infrastructure Protocol (NIP) introduces a standardized framework for depositing tokenized real-world assets. The specification outlines the syntax, semantics, and implementation details of this protocol.

6.1. Smart Contract Integration

The core functionality of the NIP is facilitated through smart contracts. These contracts are deployed on a blockchain network to ensure interoperability with existing NFT standards.

  • 6.1.1. Facility Ownership Contract
    • Defines the ownership of the real-world asset facility.
    • Contains functions for transferring ownership securely through cryptographic signatures.
    • Integrates with the NFT mint service for seamless tokenization.
  • 6.1.2. Deposit Contract
    • Manages the depositing process of tokenized objects into the facility.
    • Includes functions for initiating deposits, verifying token authenticity, and updating ownership records.
    • Utilizes decentralized identifiers (DIDs) for unique identification of tokenized assets.

6.2. Data Structures

The NIP introduces new data structures to store relevant information securely on the blockchain.

  • 6.2.1. Asset Metadata
    • Contains detailed information about the tokenized real-world asset, including its physical characteristics, origin, and any associated metadata.
    • Conforms to existing metadata standards for NFTs, ensuring compatibility with NFT marketplaces.
  • 6.2.2. Ownership Records
    • Maintains a transparent and immutable record of asset ownership changes.
    • Captures the timestamp, transaction details, and parties involved in each ownership transfer.

6.3. NFT Mint Service Integration

The NIP collaborates with NFT mint services for the tokenization of real-world assets.

  • 6.3.1. Mint Function
    • The NIP integrates with the mint service to create NFTs representing tokenized assets.
    • The mint function embeds a reference to the deposit contract, ensuring traceability.
  • 6.3.2. Token Authenticity Verification
    • The NIP mandates the mint service to verify the authenticity of tokenized assets before initiating the deposit process.
    • Utilizes cryptographic methods to ensure the integrity of tokenized content.

6.4. Depository Ownership and Storage

Owners of depositories play a crucial role in the NIP.

  • 6.4.1. Storage Agreement Contract
    • Defines the terms and conditions of the storage service provided by depository owners.
    • Specifies storage fees, access conditions, and procedures for withdrawal.
  • 6.4.2. Withdrawal Function
    • Allows asset owners to initiate the withdrawal of their tokenized assets from the depository.
    • Implements a secure and auditable process for asset retrieval.

6.5. Interoperability

The NIP is designed to be interoperable with existing NFT standards, allowing tokenized assets to seamlessly interact with NFT marketplaces, decentralized applications (DApps), and other blockchain-based services.

6.6. Security Considerations

Security measures, including encryption and access controls, are implemented at every stage to safeguard the integrity and confidentiality of tokenized asset information.

This specification provides a foundation for developers to implement the NFT Infrastructure Protocol, ensuring a standardized and secure process for depositing tokenized real-world assets within the NFT ecosystem.

7. Open-source commitment
I commits to open-sourcing the NIP and grants permission for developers within the Mint blockchain ecosystem to build protocols and applications based on this NIP.
