Everything you need to know about NFT

Non-fungible token (NFT)

  • Unique
  • Not shareable
  • Not replaceable
  • ERC-721 protocol

Non-fungible tokens or abbreviated (NFT-Tokens) are cryptographic tokens on a blockchain that cannot be exchanged or copied, where each item or token is completely rare and represents a unique asset. Think, for example, of festival tickets. There are of course several tickets for sale for the same festival, but your ticket contains your name, seat number and a unique code, which makes your ticket unique. You would not be admitted to the festival with someone else's ticket.

Because the Non-fungible tokens are not interchangeable, they can be used as proof of authenticity and ownership within the crypto world. The NFT concept can be seen as a new concept of ownership. Today tickets are already sold through NFTs, an advantage of this is that they cannot be counterfeited and resold with high fees.

The most popular blockchain enabling NFT technology is the Ethereum blockchain. The NFT tokens conform to a standard called: ERC 721 standard proctocol. This protocol allows the tokens to be unique and cannot be shared. The protocol allows investors to get hold of these tokens in a simple way.

fungible token

  • Not unique
  • Divisible
  • Replaceable
  • ERC-20 protocol

When something is fungible, it means it is easily replaceable. An example is the euro or dollar, which is perfectly interchangeable with any other euro or dollar. These are not unique items, there are more copies of the same item. Just like physical money, cryptocurrencies are replaceable, meaning they can be traded or exchanged for each other. For example, a Bitcoin is always equal in value to another Bitcoin.

Fungible tokens use ERC20 standard protocol on the Ethereum network / blockchain. ERC20 is actually a technical specification, if a token applies these specifications it belongs to an ERC20 token.

The protocol has basic functions that every token needs to be traded. Developing and maintaining a blockchain technology is very expensive, which is why these tokens are active on the Ethereum blockchain. A major advantage of the ERC20 protocol is that a trading platform can easily add new tokens to the network to make them tradable on their platform. An example of an ERC20 are sablecoins, security tokens and utility tokens.

What are they used for?

Because NFTs are unique and cannot be copied, they often serve as collectibles or collector's items. NFTs are used for things like digital artworks, sports pictures, fashion items, gifs and purchases in the game industry where players can buy rare weapons or skins to enhance the gaming experience. NFTs are also used for serious business, including verification of educational credentials or medical history and tangible property.

Meanwhile, well-known major companies and brands such as McDonalds, Louis Vuitton, Warner Music and NBA also offer digital goods based on the NFT concept.

NFT' in the art world
