🎨 What Are Non-Fungible Tokens (NFTs)?
NFTs are unique digital assets stored on a blockchain, representing ownership or proof of authenticity of a specific item — usually digital art, collectibles, music, virtual real estate, or even gaming items.
Unlike cryptocurrencies such as Bitcoin or Ethereum (which are fungible, meaning one token is interchangeable with another), NFTs are non-fungible, meaning each token is one-of-a-kind and cannot be exchanged on a one-to-one basis.
🔑 Key Characteristics of NFTs
| Characteristic | Explanation |
|---|---|
| Uniqueness | Each NFT has a distinct identifier on the blockchain. |
| Indivisibility | NFTs cannot be divided into smaller units; you own the whole token. |
| Ownership | Proof of ownership and provenance is verifiable on-chain. |
| Interoperability | Can be used across different platforms and apps supporting the same standards. |
| Programmability | NFTs can have built-in rules via smart contracts (e.g., royalties to creators). |
🛠️ How NFTs Work
-
Creation (Minting): Digital files (art, music, videos, etc.) are "minted" as NFTs by creating a unique token on a blockchain like Ethereum.
-
Metadata: NFT stores metadata such as title, creator, ownership history, and often a link to the digital file.
-
Ownership Transfer: NFTs can be bought, sold, or transferred via blockchain marketplaces.
-
Smart Contracts: Automatically execute terms like royalties on secondary sales.
