Launched on Bitcoin mainnet by developer Casey Rodarmor on January 20, 2023, Ordinal NFTs are simply the latest way to create NFTs on Bitcoin. Ordinals are means of creating Bitcoin NFTs by attaching data such as images, videos, and more to an individual satoshi on the base Bitcoin blockchain. Unlike their predecessors, ordinal NFTs don’t exist on a separate layer from Bitcoin. Rather, they use an arbitrary but logical ordering system called ordinal theory to give each individual Bitcoin satoshi a unique number. In this regard, ordinal NFTs are completely Bitcoin-native. They work without changes to the Bitcoin protocol, don’t require any extra layers, and are backward compatible with the network.
