What is a NFT

What is NFT Token:

NFT (Non-Fungible Token) is a unique digital token based on blockchain technology that represents an irreplaceable, non-interchangeable asset or item. The key characteristic of an NFT is its non-fungibility and uniqueness, meaning each token has its own distinct value and cannot be replaced or exchanged for another token in the same way as cryptocurrencies.

Key features of NFT:

  1. Uniqueness: Each NFT is one-of-a-kind, distinguishing it from other tokens.

  2. Indivisibility: NFTs cannot be divided into smaller units, unlike some other cryptocurrencies such as Bitcoin or Ethereum.

  3. Durability: NFT data is permanently recorded on the blockchain, ensuring immutability and a public record of ownership history.

  4. Ownership: NFT ownership is decentralized and recorded on the blockchain, eliminating the need for intermediaries and providing users with full control over their digital assets.

NFT Token Standards: It is also worth noting that there are different NFT token standards, with two of the most popular being ERC721 and ERC1155.


  • One of the earliest NFT token standards.

  • Each ERC721 token is unique, making it ideal for representing one-of-a-kind assets, such as digital art.

  • Commonly used in projects related to collecting and digital art.


  • Introduces a more flexible model, allowing for the issuance of both unique and fungible tokens.

  • Ideal for games where different access levels or a variety of items are needed.

The differences between these standards provide developers with various options to tailor NFTs to specific use cases.
