Are you ready to better understand one of the most used terms in society in recent years?
What is NFT?

The acronym NFT stands for “Non-Fungible Token” or “Non-Fungible Token” in Portuguese. Although the translation of the acronym doesn’t explain much, it’s quite easy to understand the topic after exploring it a little better.
NFT is a type of cryptocurrency that represents ownership or authenticity of a unique or collectible digital item, such as artwork, music, videos, gifs, memes, and even tweets.
Unlike traditional and more popular cryptocurrencies when we talk about the subject – such as Bitcoin or Ethereum, which are fungible (that is, they can be replaced by each other) – non-fungible tokens are unique and cannot be replicated. This is because they are based on blockchain technology – usually using the Ethereum network – which guarantees the authenticity, transparency and security of transactions.
Each NFT has a unique record on a blockchain that proves ownership and authenticity of the digital item associated with it. This feature makes NFTs very valuable to artists, creators, and collectors, as they can sell or auction their unique digital items directly to buyers, without the need for intermediaries.
NFTs also allow artists to receive royalties when their digital items are resold on the secondary market. This functionality is implemented automatically through blockchain smart contracts, ensuring that creators continue to receive a percentage of future sales.
While NFTs have gained a lot of popularity in the digital art and collectibles world, they have also been the subject of debate and criticism related to environmental sustainability, financial speculation, and lack of regulation. It is important to do careful research and be aware of the risks before getting involved with NFTs.

What is NFT for?
Now it’s time to understand once and for all what NFTs are for in a practical and easy way!
Imagine you have a special sticker album, where each sticker is unique and cannot be replaced by another. Each sticker has its own value, and some are rarer or more desired than others.
Now, apply this concept to the digital world. NFTs are like unique digital trading cards. They serve to represent ownership or authenticity of a specific digital item, such as an image, a video, a song, or even a tweet.
Let’s take a digital artwork as an example. An artist creates a unique painting and decides to turn it into an NFT. By doing so, they create a special record, using a technology called blockchain, that proves that they are the original creator of that artwork.
This artwork can now be sold as an NFT. If someone buys the NFT, they become the sole owner of that digital item. While others may make copies of the image itself, only the owner of the NFT owns the original and can prove that they are the rightful owner.
NFTs can also be bought and sold on the secondary market. This means that if the owner of the NFT decides to sell it in the future, they can do so and transfer ownership to someone else. And, most interestingly, NFT creators can receive a percentage of future sales every time the digital item is resold.
Although the term is no longer as popular as it was a few years ago, NFTs have become very popular, especially in the world of digital art, music and collectibles, because they allow artists and creators to monetize their work directly and independently, without the need for intermediaries.
The main controversies involving NFT
As a topic that has taken over the world – and, at the same time, become the subject of the most diverse conversations – it is clear that NFT has been involved in controversy.
Below, we list some of the main ones:
Environmental sustainability
As we’ve discussed here, the creation and trading of NFTs is based on blockchains like Ethereum, which consume a significant amount of energy. This has led to concerns about the environmental impact of these transactions, especially given the large number of NFTs being created and traded.
Copyright and Intellectual Property
This can be considered the biggest “controversy” involving the term NFT.
While NFTs provide a record of ownership, there are concerns about how they affect copyright and intellectual property. Owning an NFT does not necessarily mean that someone has the right to use the associated content in ways beyond mere possession.
Frauds and scams
Another controversy that accompanied the term during the time that NFTs were on the rise around the world is in relation to scams and possible frauds involving the term.
With the growing popularity of NFTs, cases of scams and counterfeits have emerged. Some malicious individuals attempt to sell NFTs of artwork or digital items that do not have the legitimate rights or authenticity.
