What are NFTs?

Simply put, Non-Fungible Tokens or NFTs are a digital representation of unique assets. Art pieces, music albums, sports trading cards, limited edition clothing, are all examples of physical unique assets that people have been collecting for ages now. What gives value to these assets is their uniqueness and scarcity that can be verified by analyzing specific traits, serial numbers, with manual verification processes, among others. NFTs augment these traditional verification processes by allowing all these physical assets and also digital assets, such as digital artworks or music albums, to be digitally represented in a trustworthy, secure, and transparent way.

  • Limited: The value of NFTs comes from their scarcity so, just like in traditional physical collectibles, being the owner of something that only has 10 copies of it is different from owning something that has 1 million copies of it.
  • Indivisible: NFTs are indivisible into smaller units. You either buy the complete digital item or buy no item. However, this is evolving with social tokens and shared ownership.
  • Unique: NFTs have a strong information tab that explains their uniqueness and makes it so that it can’t be replaced for something else. This information is fully secured and genuine via blockchain technology.

What are the benefits and challenges of NFTs?

Since NFTs are based on blockchain, they get all the benefits of the technology. Some of these benefits are:

  • Easily Transferable: NFTs are purchased and sold by anyone around the world on special marketplaces, such as OpenSea and Rarible. After bought, owners can do whatever they please with their NFTs (we go over some of the use cases in the next section), including selling them to another person.
  • Trustworthy: The chain of custody allows you to know that your NFT is accurate since it’s hard to create counterfeits with a decentralized and permanent record.
  • Maintain Ownership Rights: This refers to an NFT’s worth of decentralized platforms that guarantee provenance and no purchaser can change the data later.
  • Environmental Implications: proof-of-work (PoW) blockchain, such as Ethereum in which most NFTs operate today, requires an immense energy consumption due to the computationally intensive mining process needed to secure and verify every transaction happening in the chain.
  • Security: Blockchain is one of the (if not the) most secure ways to store digital items. But users are the ones responsible for storing their own keys to access their NFTs and for adopting secure practices on marketplaces or other front-end applications that are subject to cyber-attacks.
  • Manual Work: One of the biggest advantages of NFTs or any blockchain-based technology is its chain of custody that allows for traceability. But accessing this information is cumbersome and marketplaces are not taking responsibility for this process. This makes it easy for anyone to say they are the creators of the specific NFT without actually being it.
  • Speculation: We are arguably in the middle of a hype cycle. Transactions are happening in extremely high values and there are many startups in the space raising funds at extremely high valuations. We are yet to see if we are in a speculative bubble or not.

What are NFTs useful for?


It has been a while since people started discussing how blockchain can help solve some of the music industry’s main challenges. With the technology’s proof of ownership and transparent record of transactions, labels can streamline the notoriously complex rights management and royalty payout process, and artists are consequently able to receive streaming money instantaneously and have a clearer view of their current income streams.


Digital artists have long struggled to make relevant amounts of money mainly due to how easy it is for anyone to copy the digital files of the art pieces without paying for them. By turning their creations into NFTs, digital artists can get much more value out of them as collectors are attracted to the scarcity, proof of ownership, and traceability of the piece, making them prone to spend more on these assets.


Gamers are no strangers to trading digital collectibles. In fact, they have been buying digital clothes (skins), items, weapons, and many other things for their game character for years now. However, there was no way for them to actually prove the scarcity of a rare item they acquired, sell it to other players or even take items bought in one game and bring them to be used in another game. These are all possible now with the use of NFTs.


I imagine all of us have or know someone who has already bought a fake ticket or paid much more than the original price of a ticket to a music concert or sports event. NFTs are perfect for combating identification fraud, meaning buyers of a secondary ticket sale can track the origins of the ticket, avoid buying fake ones and ultimately prove their ownership to the event organizer. Additionally, event organizers will be able to track the prices of these secondary sales and prevent people from charging exorbitant prices for tickets. After attending the event, the attendees will have their NFT tickets forever as they are immutable and permanent, allowing them to even resell them to fans who might be interested.

Real Estate

NFTs have several potential applications to real estate. The process of buying and selling physical real estate today is cumbersome, requiring a lot of paperwork and manual work. By issuing an NFT tied to the property, it becomes much easier to trade and manage the real-life asset as it instantly makes the history of transactions with that piece transparent and immutable. A startup called Propy is ahead of the curve here and already auctioned a real apartment as an NFT that will transfer ownership of the real estate to a future buyer almost instantly.

Financial Services

NFTs may be central to Decentralized Financing (DeFi), which are fintech projects that use cryptocurrency and the blockchain to disrupt existing financial intermediaries. Right now, if you want to get a loan, you need to go to a bank, go through all the paperwork and KYC processes to potentially get approved. With DeFi, anyone will be able to use an NFT, such as valuable digital art, physical real estate, or any other asset they might own as collateral and get the loan without even going through a bank.

Other Collectibles

Art and music are certainly collectibles, but NFTs also work for basically any other kind of collectible. NBA top shot, for example, is currently one of the most successful NFT projects and allows people to buy and own moments of basketball games working similarly to real-life sports trading cards. Cryptokitties is also another great example of a project that basically started the NFTs market that lets users collect digital cats with different traits and actually take care of them, much like virtual Tamagotchi for anyone who remembers these.
