Frequently Asked Questions
The concept of fungibility refers to the ability for an asset to be exchanged equivalently with another asset of like kind. A practical example of a fungible asset is the US Dollar, where you can trade one dollar for another knowing the value is exactly the same regardless of which dollar you have.
In contrast to fungible assets, non-fungible assets are valued differently based on their unique attributes and scarcity. One example of this is baseball cards, where each individual baseball card is assigned a unique value depending on its attributes such as edition number, design, player, and rarity. Baseball cards are not fungible because every baseball card is different and therefore cannot be exchanged directly for any other baseball card.
Non-fungible tokens, often referred to as NFTs, are blockchain-based tokens that each represent a unique asset like a piece of art, digital content, or media. An NFT can be thought of as an irrevocable digital certificate of ownership and authenticity for a given asset, whether digital or physical.
NFTs can be created to represent virtually any asset, whether physical, digital or metaphysical. However, the most common NFT assets are digital art, digital collectible items, pieces of content like video or audio, and event tickets.
Non-fungible tokens (NFTs) are designed to be 1) cryptographically verifiable, 2) unique or scarce, and 3) easily transferable.
By using the cryptographic signatures native to the blockchain on which an NFT is issued, one can easily determine the origin and the current owner of the asset in seconds.
Smart contracts are simple programs stored on a blockchain that run when predetermined conditions are met. They typically are used to automate the execution of an agreement so that all participants can be immediately certain of the outcome, without any intermediary’s involvement or time loss.
Smart contracts are the primary means by which developers can create and manage NFTs on a blockchain. Smart contracts track who owns which NFT, and what needs to happen when that ownership changes (for example, what percent of the sale needs to be paid to the creator as a royalty).
An NFT is created by an artist, creator, or license-holder through a process called minting. Minting is a process that involves signing a blockchain transaction that outlines the fundamental token details, which is then broadcasted to the blockchain to trigger a smart contract function which creates the token and assigns it to its owner.
Under the hood, an NFT consists of a unique token identifier, or token ID, which is mapped to an owner identifier and stored inside a smart contract. When the owner of a given token ID wishes to transfer it to another user, it is easy to verify ownership and reassign the token to a new owner.
- NFT event tickets — companies can distribute and sell tickets to events using NFTs, reducing friction for verification of ownership and authenticity and helping to eliminate fraud. Furthermore, there are infinite possibilities for post-purchase collectability of tickets through exclusive experiences and digital art.
- Fan/customer engagement – brands or organizations can issue or sell NFTs that represent exclusive collectibles, products, experiences, or voting rights for the future development of a product or service in order to deepen the engagement customers / fans have with the brand/organization.
- In-game items – video games are walled gardens today, players do not own their digital items and secondary markets are hard to implement. NFTs can be used to create a widely varied ecosystem of in game digital items that can be bought sold and exchanged on open secondary markets and used across a broader gaming ecosystem rather than anchored to one game.
- Digital collectibles – organizations or individuals who have a well-defined brand can create NFTs that can be sold on the open market to fans or brand-loyal customers as collectibles. Think of a company like Disney that has huge brands of licensed universes like Star Wars and Marvel.
- Credentialing – identity credentials like driver’s licenses or professional certifications like AWS’ wide range of cloud certificates can be issued as NFTs to reduce the burden of proof for these credentials and eliminate the siloed nature of credentials today
- Royalties – NF’s can track fractional ownership or royalty entitlement for a piece of media or content or art.
There are various challenges and risks that may affect the adoption of NFTs. Here are some of the biggest ones:
- Complexity: The technology and tooling behind non-fungible tokens and the decentralized applications (dapps) that underpin them are still nascent despite the increasing adoption amongst startups and enterprises alike; Many of the complexities associated with building NFT-related solutions are not yet abstracted by quality tooling.
- Regulatory/Legal Implications: With the introduction of new and innovative technologies, particularly ones that involve speculative or high-value assets, come distinct regulatory and legal considerations including but not limited to know your customer procedures, anti money laundering mechanisms, and securities law compliance.
- Rapid Innovation: The rapid pace of innovation in the NFT ecosystem and the blockchain networks on which they are issued present challenges for those adopting the technology in the form of consistent change; agility and modularity are critical.
- Concerns Regarding Ecological Impact: Controversy continues in regard to the impact that energy-intensive blockchain networks that utilize the Proof-of-Work consensus mechanism have on climate change, and NFT-focused products have been a target for such criticism. However, solutions already exist to ameliorate this concern, such as the adoption of less energy-intensive consensus mechanisms and the use of “Layer 2” or L2 networks where transactions that mint NFTs can be validated more rapidly and efficiently outside of the main blockchain network. For example, the Ethereum blockchain network is well on its way to shifting towards the more energy-efficient Proof-of-Stake consensus mechanism in its Ethereum 2.0 launch, and Layer 2 solutions like Polygon and ImmutableX are already helping reduce the load today.
