OrdinalsORDI

Ordinals NFT were launched on the Bitcoin mainnet on January 20, 2023, by developer Casey Rodarmor. They represent a new approach to creating NFTs on Bitcoin. Ordinals work by attaching data such as images and videos to individual satoshis on the underlying Bitcoin blockchain to create Bitcoin-based NFTs. Unlike their predecessors, Ordinals NFTs do not exist on a separate layer from Bitcoin. Instead, they use an arbitrary but logical sorting system called ordinal theory to assign a unique number to each Bitcoin satoshi. In this regard, Ordinals NFTs are completely native to Bitcoin. They operate without altering the Bitcoin protocol, require no additional layers, and are backward compatible with the network.
