NFTs, Explained


Everyone has probably heard about NFTs by now. If you haven’t, you’ve been living in a cave. They’ve become a cultural phenomenon in just the last year. Some individuals despise them, while others believe they will be the future of anything and everything. But, no matter where you land on this spectrum, there’s a lot to absorb here, including a thriving $13 billion industry vying to become the Amazon of NFTs. But first, let’s agree on what an NFT is.


What is NFT

NFT is an abbreviation for Non-Fungible Token. Because something is non-fungible, it cannot be traded for another item. For example, one work of art is not the same as another. Both have distinct characteristics.

Other than that, things that can be exchanged for each other are called “fungible” things. One dollar or Bitcoin, for example, is always equal to another. NFTs are blockchain-based tokens that represent unique item ownership.

Because digital material can be easily copied and spread, it is hard to figure out who owns it. So, how can you show who owns the original file when everyone has an identical copy? This issue is solved by NFTs. Think of a piece of digital art that you’ve made on your computer as a JPG. This can be used to generate or mint an NFT.

The NFT that represents your art comprises information about it, such as the file’s unique fingerprint, a token name, and a symbol. This token is then held on a blockchain, with the artist, as the owner. You now can sell that token by submitting a transaction to the blockchain.


The blockchain ensures that this data is never altered. It also allows you to see who currently owns a token and just how much it has already been sold for in the past.

Artwork is not stored on either NFT or blockchain. Only its properties, such as the file’s fingerprint or hash, a token name and symbol, and potentially a link to an IPFS  hosted file, are permitted.

Using the NFT, a digital image can be traced back to its originator, who connected it to the blockchain, who purchased it, and who has held it all along. That is exactly what the NFT is. On the blockchain, which is a public digital ledger that records decentralized internet transactions, these transactions are recorded. To hack or fool the system is nearly hard because all modifications are made public and validated simultaneously by so many computers.


Things you can do with NFTs

When you purchase an NFT that symbolizes artwork, you do not receive a tangible copy of the artwork. Most of the time, anyone can get a free copy. In a blockchain, the NFT simply indicates ownership, which cannot be tampered with because it is recorded in the blockchain. NFTs provide you with digital bragging rights. While the original art is owned by the token owner, the author of the NFT maintains the copyright and reproduction rights.

So, while an artist can sell his original art as an NFT, he can also sell prints. For example, you can sell concert tickets with NFTs. You can also use them to sell domain names and rare in-game goods. You can also use them to sell real estate.

For example, Twitter’s creator sold his first tweet as an NFT. Anyone can read that tweet on his profile, but it is now owned by only one individual. And that guy spent more than $2.9 million on it.


Who can buy NFTs

The big question is whether or not anyone can purchase an NFT. It is tough to find a cheap piece for everyone’s pocket because it is a budding and thriving market. Because the items are typically sold on Ethereum, it is important to first own assets of this cryptocurrency, which is currently valued at roughly 2.7 thousand dollars per ether (ETH) at the time of writing this article.

NFTs can be purchased by the general public because they are available on platforms that are open to the public, such as  Opensea, Rarible, and Sorare.

OpenSea is currently worth more than $13 billion. They aspire to be the Amazon of NFTs. OpenSea offers an art gallery approach in which they have specific NFTs that they enjoy and anyone can go there because they want this specific type. It’s curated and managed.



All visible blockchain activity is subject to the same moral conundrum: how much energy does it consume? While there are no official data, Digieconomist estimates that the Ethereum network consumes 46.54 kg of CO2 each transaction. However, when mining, auctions, auction cancellations, sale, and transfer of ownership values are included, it can exceed 200 kg of CO2.

After analyzing the issue, Ethereum released Ethereum 2.0 at the start of 2021. The mining work, which needs GPUs (Graphics Processing Units) to execute the transactions, will be eliminated with this more efficient approach. Moving your PoW (Proof-of-work) system to PoS (Proof-of-stake) will result in a 99 percent reduction in your energy cost. Ethereum predicts that this methodological shift will occur in the second quarter of 2022.
