A Primer on Non-Fungible Tokens and Smart Contracts

A Primer on Non-Fungible Tokens and Smart Contracts

A series of lucrative auctions in the early months of 2021 has brought international attention to non-fungible tokens, or NFTs – a new type of asset that is widely misunderstood. Here, Shane Wax of Gottlieb, Rackman & Reisman, offers Lawyer Monthly an analysis of how NFTs work and from where they derive their value.

By now you have likely heard about the latest technology craze: Non-Fungible Tokens (NFTs).

In 2021 alone, we have seen A-list names like Michael Jordan, Mark Cuban and 2 Chainz investing millions in NFT-based start-ups and auctions for NFT-linked assets fetching astounding sums of money, including Jack Dorsey’s first tweet ($2.9 million) and collections of digital artworks by Grimes ($6 million) and “Beeple” ($69 million), just to scratch the surface.[i]

While often linked to digital assets, NFTs (and Smart Contracts) can also be used to sell discrete physical assets like one-of-a-kind sneakers, vinyl records and concert tickets,[ii] and the future could see their use in transactions for major purchases like cars and houses. However, before you or your clients start minting, selling, buying or trading NFTs, you should understand what NFTs and Smart Contracts are, the rights involved in NFT transactions, and some lurking dangers.

What are NFTs? A “token” is a digital asset stored on a secure, but transparent distributed blockchain ledger. Non-fungible means one-of-a-kind—like a record-breaking homerun ball, a bootleg concert recording, or collectables like baseball cards. Thus, an NFT is a digital asset that is linked to a discrete and unique asset. In contrast, a fungible token such as Bitcoin is an asset in itself—its value fluctuates relative to other currencies, but all bitcoins are the same and equal fractioned amounts of bitcoin will have equal value against each other. The process of creating an NFT is called “minting.”

Like Bitcoin, NFTs enjoy the security, transparency and immutability of cryptographic storage, but whereas bitcoins are divisible to 10-8 degree, NFTs are indivisible and can store significant amounts of data, including unique information. This is what makes a particular token “non-fungible,” and it is stored in a “Smart Contract,” computer code that automatically executes upon the occurrence of a set of preconditions.

Combining a Smart Contract with other unique identifying metadata — such as the identity of the owner, and secure file links — along with the security afforded by blockchain, provides practically irrefutable proof of ownership and authenticity to prospective buyers.[iii] Smart Contracts can prevent someone from transferring an NFT or accessing an underlying asset unless all preconditions specified in the contract are satisfied, including potentially paying royalties on the resale of the NFT. While most early NFTs can be resold without restrictions, some NFT marketplaces are encoded to enforce Smart Contracts royalty “clauses” which, upon the resale of an NFT, automatically pay a fee to the minter-seller, usually as a fixed percentage of the resale price.[iv]

In layman’s terms, NFTs and Smart Contracts act simultaneously as a “certificate of authenticity” for the underlying asset and as a valuable representation of ownership of a real asset like a stock.

While NFT auctions have yielded jaw-dropping real dollar figures, what does a buyer really possess? Ultimately, an NFT owner has access to the underlying asset, but they may lack exclusive access to or control of the asset, let alone ownership of the asset or any intellectual property (IP). Indeed, the default rule is that a patentee or copyright owner retains all IP unless it is clear from the language of a signed writing (e.g. the Smart Contract) that ownership of an intellectual property right is being transferred.[v] In most cases, Smart Contracts do not transfer IP rights.

In layman’s terms, NFTs and Smart Contracts act simultaneously as a “certificate of authenticity” for the underlying asset and as a valuable representation of ownership of a real asset like a stock.

An NFT owner may have an implied license in the same way that the purchaser of a useful machine is not infringing a patent by using it as intended or how the purchaser of music is not infringing copyrights by privately singing along with their copy of a record. For example, hundreds of people bought the NFT version of the new Kings of Leon album and received exclusive digital and physical collectibles, but the same music was released via traditional streaming and purchase outlets and the Kings of Leon (or their label) still retain all copyrights. In collectible cases like this, owning an NFT is like owning one of the roughly 10,000 copies of Nolan Ryan’s 1968 Topps rookie card, with the added bonus that your version of the card is authenticated and you are provably the owner. Thus, the value in buying an NFT is often in creating a collectible (non-fungible) version of an otherwise a replicable (fungible) asset.

Despite the security offered by blockchain, this new industry is ripe for fraud and misuse, particularly in attempts to mint and sell NFTs linked to assets not owned by the minter-seller, be it a copyrighted work, trademarked brand or celebrity likeness. In a recent example, an NFT auction for a drawing by Jean-Michel Basquiat that purportedly included “reproduction and IP rights…in perpetuity” was pulled after Basquiat’s estate clarified that it still owned all copyrights in the sketch and that the NFT seller had no rights to give away.[vi]

While there are no laws yet relating to cryptographic assets, legal systems should largely be able to adapt existing laws and principles to blockchain technology as was done for online activities. For starters, most disputes between a buyer and seller of NFTs should be easily resolved either by the Smart Contract or by a judge applying traditional principles of contract law. In Internet-based copyright infringement lawsuits between parties of different nationalities, US courts apply a two-step “conflict of laws” analysis, determining the validity of the IP right under the laws of the nation where the work was created, and determining liability for infringement under the laws of the nation where the tort occurred. Similar rules could apply to this context.

While there are no laws yet relating to cryptographic assets, legal systems should largely be able to adapt existing laws and principles to blockchain technology as was done for online activities.

Another issue is that, since NFTs are, in the end, data stored in cyberspace, there is a risk of non-permanency and losing access to digital assets linked to NFTs. In the meantime, the NFT craze is just beginning and we can either continue to gawk at lofty sales or join the fray.
