How NFTs Work

NFTs are created through a process called minting, in which the information of the NFT is recorded on a blockchain. At a high level, the minting process entails a new block being created, NFT information being validated by a validator, and the block being closed. This minting process often entails incorporating smart contracts that assign ownership and manage the transferability of the NFT.

As tokens are minted, they are assigned a unique identifier directly linked to one blockchain address. Each token has an owner, and the ownership information (i.e., the address in which the minted token resides) is publicly available. Even if 5,000 NFTs of the same exact item are minted (similar to general admission tickets to a movie), each token has a unique identifier and can be distinguished from the others.

Like the traditional tokenized NFT, a Bitcoin Ordinal can be bought, sold, and traded. The difference is NFTs inscribe serial numbers to the work of art or music and Bitcoin Ordinals have identifiers inscribed to the satoshis—the smallest chain denomination.
