What Are NFTs?

Non-Fungible Tokens (NFTs) are unique digital assets stored and managed on a blockchain, a decentralized digital ledger technology. Each NFT is distinct and cannot be replicated, making it one-of-a-kind. Unlike cryptocurrencies such as Bitcoin or Ethereum, which are fungible and can be exchanged one-to-one, NFTs represent ownership of specific digital content or assets, such as artwork, collectibles, virtual real estate, music, videos, or any other form of digital media. Each NFT contains metadata that verifies its authenticity, ownership history, and other relevant information, providing a transparent and immutable record of ownership.

How NFTs Differ From Cryptocurrencies Like Bitcoin

NFTs differ from cryptocurrencies like Bitcoin in several key ways. While both are digital assets that utilize blockchain technology, they serve different purposes and have different properties:


  • Cryptocurrencies like Bitcoin are fungible, meaning that each unit is identical and interchangeable with any other unit of the same denomination. For example, one Bitcoin is equivalent in value to any other Bitcoin.
  • In contrast, NFTs are non-fungible, meaning each token is unique and cannot be exchanged like-for-like. Each NFT represents ownership of a specific asset, and no two NFTs are identical.

Use case

  • Cryptocurrencies like Bitcoin are primarily used as a medium of exchange or store of value, functioning as digital currencies that can be traded or spent. 
  • NFTs, on the other hand, represent ownership of digital content or assets. They can be bought, sold, and traded like any other asset, but their value is derived from their uniqueness and scarcity rather than their utility as a medium of exchange.


While cryptocurrencies like Bitcoin are generally interchangeable across different platforms and wallets, NFTs are often specific to particular blockchain networks or marketplaces. However, efforts are underway to improve interoperability and enable cross-chain compatibility for NFTs, allowing them to be transferred and traded more freely between different platforms and ecosystems.

Understanding Fungibility vs. Non-fungibility

  • Fungibility refers to the property of an asset whereby each unit is interchangeable and indistinguishable from any other unit of the same type. For example, a dollar bill is fungible because one dollar bill is equivalent to any other dollar bill.
  • Non-fungibility refers to the property of an asset whereby each unit is unique and cannot be exchanged on a like-for-like basis. Non-fungible assets have distinct characteristics or properties that differentiate them from one another. For example, a piece of artwork is non-fungible because each artwork is unique and cannot be replaced by any other artwork of the same type.


    How NFTs Work

    Blockchain technology is the underlying infrastructure that enables the creation, management, and transfer of NFTs. It is a decentralized digital ledger that records transactions across a network of computers in a secure, transparent, and immutable manner. Each block in the blockchain contains a cryptographic hash of the previous block, creating a chain of blocks that cannot be altered retroactively.

    The decentralized nature of blockchain technology ensures that NFT transactions are transparent and resistant to censorship or tampering. When an NFT is created, its ownership information, metadata, and transaction history are recorded on the blockchain, providing a permanent and verifiable record of ownership.

    Smart Contracts and Their Role in NFT Transactions

    Smart contracts are self-executing contracts with the terms of the agreement directly written into code. They automatically enforce the terms of the contract when predefined conditions are met, without the need for intermediaries or third parties. Smart contracts play a crucial role in NFT transactions by facilitating the creation, transfer, and ownership of NFTs in a trustless and decentralized manner.

    When an NFT is created, a smart contract is deployed on the blockchain to define its rules and conditions, such as its ownership rights, royalties, and transferability. The smart contract automatically executes these rules when the NFT is bought, sold, or transferred, ensuring that ownership rights are properly transferred and enforced.

    Examples of Popular Blockchain Platforms for NFTs

    Several blockchain platforms support the creation and trading of NFTs, each with unique features and ecosystem. Some of the most popular blockchain platforms for NFTs include:

    1. Ethereum: Ethereum is one of the leading blockchain platforms for NFTs, known for its robust smart contract functionality and vibrant ecosystem of decentralized applications (DApps). The Ethereum blockchain is widely used for creating and trading NFTs thanks to its flexibility, scalability, and interoperability with other blockchain networks.
    2. Binance Smart Chain (BSC): Binance Smart Chain is a blockchain platform developed by Binance, one of the largest cryptocurrency exchanges in the world. BSC offers fast and low-cost transactions, making it an attractive option for NFT creators and traders looking to minimize transaction fees and maximize efficiency.
    3. Flow: Flow is a blockchain platform designed for building decentralized applications and digital assets, created by Dapper Labs, the team behind popular NFT projects like CryptoKitties and NBA Top Shot. Flow is optimized for scalability and performance, making it well-suited for handling large-scale NFT collections and high-volume transactions.
