NFTs, or non-fungible tokens, are unique digital assets stored on a blockchain, a decentralized digital ledger. Unlike cryptocurrencies, such as Bitcoin or Ethereum, which are interchangeable or fungible, NFTs are non-interchangeable and cannot be exchanged on a one-to-one basis due to their uniqueness. Each NFT has a distinct value based on the item it represents and the metadata attached to it.
NFTs can represent a variety of digital assets, including digital artwork, music, videos, collectibles, virtual real estate, and in-game items. The ownership of an NFT is tracked on a blockchain, typically on the Ethereum network, but other blockchains such as Binance Smart Chain and Flow also support NFTs. Once an NFT is created, or "minted," it is assigned to a unique blockchain address, which verifies ownership. This allows for transparency, as the ownership and transfer history of each NFT can be publicly verified.
NFTs are traded on decentralized marketplaces such as OpenSea, Rarible, and Foundation, where users can buy, sell, and create NFTs. The process of minting an NFT involves creating a digital asset, uploading it to a platform, and linking it to a smart contract that records the asset's information on the blockchain. NFTs can be bought directly from creators or through secondary sales, where the original creator may receive royalties from future transactions, depending on the smart contract terms.
NFTs do not grant ownership of the underlying intellectual property but provide proof of ownership or a certificate of authenticity for the digital item itself. Buyers of NFTs own the digital asset associated with the token but must follow the terms of use specified by the original creator regarding its reproduction or commercial use.
NFTs gained significant attention in 2021, with high-profile sales of digital art, music, and other digital assets on platforms like OpenSea and Rarible. The blockchain ensures that NFTs are immutable, meaning the data cannot be altered once it is recorded, further establishing the authenticity and provenance of each asset.
