What are Non-fungible tokens? 

Non-fungible tokens, or NFTs, are unique crypto assets. They can be wont to represent both tangible and intangible items. A tangible product may be an object which will be touched like a building, gadget, etc whereas an intangible product can only be perceived indirectly. Fungibility is that the ability of an asset to be interchanged for an additional of an alike item for instance gold, dollar, etc. Non- fungibility is the ability of an asset to be irreplaceable or unique for example art, etc.

A non-fungible token may be a digital certificate of authenticity and credibility that you simply own something collectively referred to as the blockchain. It keeps a record of your transaction history. NFT is opening an ingenious platform for underrated goods and giving collectors a simple way of collecting arts digitally. Non-fungible tokens (NFTs) are evolving with time and industry growth. Beeple is a popular name emerging in the NFTs world. Read below to explore how NFTs work, and how they’re being used.

How are non-fungible tokens(NFTs) used:

Non-fungible tokens (NFTs) are often used for digital assets or goods that are different from one another to prove their worth and rarity. They can represent and supply digital acceptance to everything from virtual games to artworks etc.

Non-fungible tokens aren’t traded on standard and traditional exchanges, instead, they’re purchased or sold on digital arena or marketplaces.

How do NFTs work:

Non-fungible tokens are often created on contract-enabled blockchains with non-fungible token tools and support. Ethereum was the primary to be widely used, NEO, EOS, etc now even have NFT standards.

Non-fungible tokens and their smart contracts leave detailed information to be added, just like the identity of the owner, etc. The potential of non-fungible tokens is to supply proof of digital ownership of an asset within the digital world making the straightforward flow of buy and sell on non-fungible items.

An NFT (non-fungible token) may be a special cryptographically-generated token that uses blockchain technology to link with a singular digital asset that can’t be replicated. non-fungible tokens differ from popular cryptocurrencies such as Ether (ETH), Bitcoin (BTC), and Monero (MXR), which are fungible; for example, you can exchange one Bitcoin for any other Bitcoin.

Although the usage of NFTs has spread in various industries, they’re synonymously related to the gaming and digital collectibles sectors and are most ordinarily found as a selected Ethereum token built on the ERC-721 standard. However, in 2021, their use is beginning to spread to other blockchains like Binance Smart Chain’s BEP-721 protocol.

What Is Fungibility?

Fungibility refers to an asset’s ability to be exchanged with a similar asset without sacrificing its value. Fungibility also defines an asset’s characteristics, like divisibility and value.

In the cryptocurrency sector, one BTC has the same value as any other BTC. However, the sport changes once we cross over to non-fungible tokens. An NFT crypto token features a distinct value from the other similar token. Individual characteristics dictate their uniqueness, hence, they’re non-fungible, very similar to real-world assets like rare stones, works of art, and collector luxury items.

What Are Fungible Tokens?

Fungible tokens are tokens that are tradable for every other, and their value remains constant. In the above example, Bitcoin may be a fungible token because it’s an equivalent value no matter its owner or history.

Characteristics of Non-Fungible Tokens

Rare – the worth of NFTs comes from their scarcity. Although NFT developers can create any amount of non-fungible tokens, they often limit the tokens to extend rarity.

Indivisible – Although not set in stone, most non-fungible tokens are indivisible into smaller units. You either purchase the whole amount of, say, a digital art piece or purchase no art in the least.

Unique – This is perhaps the most significant characteristic of them all. NFTs have a permanent information tab that records their uniqueness. Think of this information as a certificate of authenticity.

Advantages of NFTs

The Non-fungible tokens bring a replacement dimension to digital interactions.

The three leading advantages of NFTs are:

They’re transferable – Unlike exchange-traded fungible tokens, NFTs are bought or sold on special marketplaces. However, their value depends on their uniqueness.

They’re authentic – Blockchain technology powers non-fungible tokens. Therefore, you know that your NFT is genuine since it’s nearly impossible to create counterfeits with a decentralized immutable ledger.

They preserve ownership rights – Again, this refers to an NFT’s use of decentralized platforms where no owner can alter the info once committed.

Non-Fungible Token Use Cases


NFTs are popular within the gaming industry since these tokens solve a number of their inherent problems. For example, top games like Fortnite prohibit the sale of rare traits and accessories like weapons and skins.

However, with NFTs, these features can easily be transferred and utilized in different games. As such, non-fungible tokens can help drive in-game economies.

Digital Assets

Think of Decentraland. Here, participants can buy virtual land. Another example that’s closer to the house is ENS (Ethereum Name Service), which uses NFTs for its. ETH domains to facilitate buying and selling.


NFTs are ideal for fighting identity theft. Examples of things that will be digitized to represent identity include academic qualifications, medical records, and even our appearances.

Furthermore, digital artists can turn their work into NFTs for copyright purposes.

NFT’s use to prove identity includes converting physical game tickets into non-fungible tokens to weed out counterfeits.


NFTs, bring a new dawn to the collectible world. Consequently, conventional collectors are now onto digital assets.

What Are ERC-721 tokens?

An ERC-721 token may be a term used loosely to explain non-fungible tokens. Breaking down the term, ERC-721 refers to guiding standards when creating NFTs atop the Ethereum blockchain. Therefore, this is often a token type that’s built to support Ethereum’s ERC-721 standard.

Apart from Ethereum, NFTs can survive other decentralized networks like EOS and NEO. However, these platforms must have smart contract-capability and a box filled with NFT tools. Smart contracts, during this case, enable the inclusion of detailed descriptions like metadata.
