NFTs, or Non-Fungible Tokens, are unique digital assets stored on a blockchain, typically Ethereum, that prove ownership and authenticity of a specific item, like art, music, or virtual collectibles. Unlike cryptocurrencies such as Bitcoin, which are interchangeable (fungible), each NFT has distinct data, making it one-of-a-kind and non-replaceable. They work by leveraging blockchain’s secure, transparent ledger to record ownership and transaction history.
For example, an artist can mint an NFT for a digital artwork, and the buyer’s ownership is verified on the blockchain, ensuring it can’t be duplicated or forged. NFTs often include metadata, like the creator’s details or a link to the digital file, though the file itself (e.g., an image) is usually hosted off-chain, which can raise concerns about long-term accessibility.
