Introduction
Blockchain technology, as a pivotal innovation transitioning from the information internet to the value internet, has demonstrated unparalleled potential through its integration with digital assets. Unlike fungible tokens such as cryptocurrencies (e.g., Bitcoin), Non-Fungible Tokens (NFTs) represent unique digital assets, enabling verifiable ownership and scarcity for digital art, collectibles, and more. Notable examples include:
- Banksy’s burned artwork sold as an NFT for $380,000.
- Twitter CEO Jack Dorsey’s first tweet auctioned for $2.9 million.
- Beeple’s digital artwork fetching $69.3 million at Christie’s.
NFTs leverage standards like Ethereum’s ERC-721 to ensure uniqueness, immutability, and programmability via smart contracts. However, their rapid adoption raises complex legal questions regarding property rights, intellectual property (IP) protection, and regulatory frameworks.
Overview of NFT Development
(1) Market Logic Behind NFTs
NFTs thrive due to two core attributes:
- Scarcity: Blockchain ensures non-replicability and tamper-proof records.
- Uniqueness: Aligns with human valuation of rare and distinctive assets.
Each NFT is a unique data unit (hash function) recorded on-chain, functioning like a digital fingerprint for assets ranging from art to virtual real estate.
(2) Key Applications
- Digital Art: Platforms like SuperRare and Rarible enable provenance tracking and royalty automation.
- Gaming: Axie Infinity allows players to own and trade in-game assets.
- Metaverse: NFTs underpin virtual economies (e.g., Decentraland).
- Physical Asset Tokenization: Real estate and luxury goods gain liquidity via NFTs (e.g., Red Swan’s $22B property tokenization).
(3) Technical Foundations
Standards:
- ERC-721: Ensures indivisible, unique tokens.
- ERC-1155: Supports semi-fungible asset classes (e.g., game item categories).
- Metadata: Stored on-chain (immutable) or off-chain (e.g., IPFS).
Intellectual Property Protection for NFTs
(1) Ownership vs. IP Rights
- Holding an NFT does not inherently transfer copyright. Example: NBA Top Shot buyers own the NFT but not commercial rights to the underlying video clips.
- Smart contracts can encode IP terms (e.g., perpetual royalties via EIP-2981).
(2) IP Infringement Risks
- Unauthorized Minting: Copying others’ works into NFTs (e.g., NFTifiedTweets bot scams).
- Platform Liability: Varies by jurisdiction. Some platforms (e.g., OpenSea) adopt notice-and-takedown policies, while others (e.g., SuperRare) pre-vet creators.
(3) Legal Precedents
- Case Study: A U.S. lawsuit (Rensel v. Centra Tech) debated whether NFT buyers are bound by platform terms. Courts ruled smart contract terms supersede website disclaimers.

Property Rights and NFT Transactions
(1) NFTs as Property Objects
- Characteristics: Scarcity, exclusivity, and transferability align with property law.
- Challenges: Traditional laws often require tangible assets, but NFTs redefine ownership in digital spaces.
(2) Smart Contract Legality
- Automated Execution: Smart contracts enforce terms (e.g., transferring NFT ownership upon payment).
- Dispute Resolution: Ambiguities exist—e.g., code errors may lack legal recourse pathways.
Future Applications
(1) Asset Digitization
- Securities: STOs (Security Token Offerings) tokenize stocks, bonds, and real estate.
- Carbon Credits: Blockchain tracks environmental assets.
(2) NFT Lending
Platforms like NFTfi enable collateralized loans using NFTs, addressing liquidity issues.
(3) Metaverse Integration
NFTs serve as digital deeds for virtual land, identities, and cross-platform assets.
FAQs
1. Do I own the copyright if I buy an NFT?
No, unless explicitly transferred via contract. NFT ownership typically grants usage rights, not IP.
2. How can artists protect their work from NFT theft?
Mint original works first and use platforms with robust verification (e.g., SuperRare).
3. Are NFTs considered securities?
Case-by-case. Regulatory bodies like the SEC may classify some NFTs as securities based on investment contracts.
4. Can smart contracts replace legal contracts?
Not entirely—they lack nuanced human interpretation and dispute mechanisms.
5. What’s the environmental impact of NFTs?
Ethereum’s shift to Proof-of-Stake reduces energy use. Alternatives like Tezos are eco-friendly.
Conclusion
NFTs are reshaping digital ownership, but legal frameworks must evolve to address IP rights, property laws, and smart contract enforceability. Collaborative efforts among technologists, lawmakers, and creators will ensure sustainable growth.
