Fungible vs Non-fungible tokens(NFTs): What is the difference?

The distinction between fungible and non-fungible tokens is not a novel concept in economics. Coin-like objects were sold as early as the Roman Empire, possibly as brothel or game tokens. To pay for services given by foreigners in the Middle Ages, English monasteries employed tokens known as “Abbot’s money.”

Arcade games and casino slot machines began to employ fungible tokens that could be exchanged for money in recent years. Tokens of other varieties are used in services including vehicle washes, parking garages, and public phone booths.

Tokens remain the same in the crypto era: they represent something concrete (physical) or intangible (non-physical, such as a service) within its ecosystem.


The complete guide for Complete beginners

In blockchain technology, fungible tokens are cryptocurrencies like Bitcoin.  Non-fungible tokens are units of data which represent a unique digital asset stored and verified on the blockchain.

The web 3.0 is the future of the internet and it has a lot of implications on seo and other features.

What are the types of tokens?

There are many types of tokens for any kind of service or product in the crypto space.  Payment tokens like Bitcoin or Litecoin used to run transactions in the digital world.

Utility tokens give holders access to blockchain-based services and products.

Security tokens are like traditional assets such as stocks and shares represented by digital tokens based on the blockchain technology.

Now let us see the fungible and non-fungible tokens in crypto space.

Fungible and non-fungible tokens are the two most distinct types of tokens, as discussed in this article.

What is a fungible and nonfungible token?

Understanding fungible and nonfungible tokens may be made easier if one is familiar with the concept of fungibility in economics. The only difference is that crypto tokens express their fungibility through a code script.

Fungible tokens or assets are divisible, non-unique and replicable.  For example fiat currency like a dollar is fungible:

A $1 in New York City has the same value in any country.  It can be replaceable with the currency of the other country.  A fungible token can also be a cryptocurrency like Bitcoin:

1BTC is worth 1BTC, no matter where it is used.

On the other hand, Non-fungible assets are non-divisible and unique.  They should be considered as a deed or title of ownership of a unique and non-replicable item.

A flight ticket, for example, is non-fungible because there cannot be another of the same kind due to its unique data. Because they are one-of-a-kind, a house, a boat, or a car are non-fungible physical assets.

The same is true for nonfungible tokens, which represent a single unique and indivisible item, whether physical or intangible, such as a photograph or intellectual property.

The underlying technology that can easily prove ownership of an intangible digital item is blockchain.

The main difference between fungible and nonfungible assets is the content they store.

Fungible tokens, such as Bitcoin, store in value, whereas nonfungible tokens, such as an academic title or an artwork, store in data.

How are Cryptotokens different from cryptocurrencies?

Cryptocurrencies and crypto tokens are both built on the same underlying blockchain technology.

However, cryptocurrencies are payment coins with their own blockchains. Bitcoin, Ether (ETH), and Litecoin are examples of cryptocurrencies that operate on their blockchain.

They are fungible crypto tokens that can be used to store value or as a medium to buy and sell goods.

Crypto tokens, on the other hand, are created on a different blockchain. Tokens created on Ethereum include Uniswap, Chainlink, and ERC-20.

What are fungible and nonfungible tokens in a blockchain?

Tokens on a blockchain are commonly known as crypto tokens and represent digital units of value created on current blockchain networks.

How to create tokens on the blockchain to fulfill many purposes such as transferring value, providing access to a subscription, and even voting.

The first fungible tokens, known as ERC-20, were created on the Ethereum network. They establish the standards that allow developers to create apps of different types.

The initial coin offerings era that boosted an industry and built its fortunes on ERC-20 tokens.

Non Fungible tokens have been there since the notion of coloured coins first appeared on the Bitcoin network in 2012.

Colored coins may reflect real-world products sold on the Bitcoin blockchain; however, they are tied to an external contract and must be built on trust.

A group must agree that a particular number of these coins reflect a different value entirely.

In such a situation, they may be able to transact in that value using these “designated” coins.

The digital tokens utilized are satoshis, which are tiny fractions of a Bitcoin that have been tagged or “coloured in” with information that links the currencies to real-world assets.

Colored coins were rarely used in the cryptocurrency sector. They were mostly used to create and trade artworks such as “Rare Pepe” digital cards on Counterparty, a peer-to-peer trading network built on Bitcoin’s blockchain.

The Ethereum blockchain also saw the creation of the first non fungible tokens, which were used to uniquely identify a product, service, or person.

Some NFTs are built on the Tron and EOS blockchains, which both host voting tokens.

The possibilities for this type of token are infinite, ranging from collectible things like artworks and musical works to lottery tickets and concert and sporting event tickets.

Because they are easily traceable and verifiable, NFTs can also be used as marketplaces for preserving academic titles and digital identities on the blockchain.

There is a misperception about NFTs: their perception only as artworks following their phenomenal market growth in 2020 and 2021. However, long before the arts were involved, NFTs had a significant application in the gaming business.

CryptoKitties first debuted on the Ethereum blockchain in 2017. The game was the first real-world use of NFTs in the cryptocurrency space, and it eventually became the most successful decentralized application on the Ethereum protocol.

NFTs are identified on the Ethereum blockchain using a different standard than the ERC-20, the ERC-721.

How do NFTs work, and how do you create one?

How do NFTs work, and how can you make one?

Non-fungible tokens can be produced and stored on a public blockchain, which is open to the world and accessible to anybody.

The objects they represent can be verified and traced, but the owner can stay anonymous. NFTs are created technically through smart contracts that assign ownership and govern the transferability of the NFTs.

The minting procedure involves several steps, beginning with the creation of a new block and ending with the validation and recording of data on the blockchain.

How to buy or sell a nonfungible token ?

NFTs can be bought or sold online, and they serve as digital proof of ownership for any given item.

Transactions can take place at cryptocurrency exchanges or online marketplaces such as Rarible, Nifty Gateway, or OpenSea, to name a few.

An item, like on eBay, can be sold at a fixed price set by the owner or by bidding in an auction.

The first step is to purchase a cryptocurrency such as Ether and register with one of the available platforms. The user must then transfer the cryptocurrency to a cryptocurrency wallet compatible with the tokens.

ERC-721 coins are supported by MetaMask, Trust Wallet, and Coinbase Wallet. Binance Smart Chain, Tezos, Polkadot, EOS, and Tron are among the other blockchains that support NFT transactions.

Users must, however, ensure that their chosen collectible platform is compatible with their chosen blockchain. After connecting the wallet to the platform, you can upload an image or file containing the NFT.

Users can also construct NFTs on platforms such as MakersPlace. However, they must first register and become a listed artist before they can begin working on it.

Celebrities such as Grimes, Paris Hilton, and Snoop Dogg have all increased the popularity of NFTs by publicly declaring their participation in the space.

What are the pros and cons of using non-fungible tokens?


Artists can use NFTs to claim royalties on future sales after their artwork sells for the first time. The ability to claim such future benefits is a significant breakthrough in the art industry, and it has encouraged many artists to resort to this new digital economy.

All users need to do is enable a specific blockchain function. Every time the NFT is sold or changed ownership, the system allows a profit share to be given to the artist.

For the first time, artists and content creators may monetise their work using blockchain technology, and they can do so without the intervention of a third party like an agent.


Physical galleries and auctions are also being phased out, allowing artists to migrate to the digital arena for more accessible and smoother interactions.

Digital images, like photographs, can be duplicated, with the downloaded duplicate looking identical to the original.

The potential to create unlimited reproductions of artworks has caused confusion and distrust among the artistic community.

If people can download thousands of duplicates of the original, what is the sense of paying a high price for the original?

Careful analysis reveals that digital artworks are similar to traditional art masterpieces. Someone can make an unlimited number of copies of the Mona Lisa, but only one is the original.

The question then becomes, what in the crypto world grants ownership of the original asset?

A cryptographic digital signature, sometimes known as a non-fungible token, grants someone ownership of the original work. Ownership of the work can be verified and transferred on a blockchain.

The future of NFTs

As the world becomes more and more computerized, NFTs may offer a feasible alternative for tokenizing ownership and property.

Both fungible and nonfungible tokens enable proper digitization and storage of real-world assets while also keeping them secure.

The NFT market will be worth $2.5 billion in the first half of 2021. Given the high selling prices of some of the artworks, this should come as no surprise.

“Everydays: the First 5000 Days” by digital artist Beeple was auctioned off for $69.3 million at Christie’s.

In the meantime, Twitter CEO Jack Dorsey auctioned off an NFT of his first tweet for $2.9 million.

NFTs are anticipated to revolutionize many digital markets by facilitating transactions and strengthening interpersonal relations.

NFTs, on the other hand, are investments based on demand rather than fundamentals since they are collectibles.

Bitcoin and Ether are assets whose value is based on technology advancements and economic adoption, providing more robust fundamentals to the smart investor.

People’s interest in the sector, on the other hand, and how much they are ready to pay for an NFT, determine the price of an asset, eventually dictating the future of the entire market.
