NFTs exist on a blockchain. A blockchain is a digitally distributed, decentralized, public ledger that exists across a network. As you might already know, blockchain technology also powers cryptocurrency. Currently, most NFTs are part of the Ethereum blockchain. However, it is worth noting that other blockchains can also support NFTs. Being stored on the blockchain means that the creation, ownership, and transfer of NFTs are recorded on a public ledger. As such, anyone can track the ownership of an NFT on the blockchain.
