Launched on the Mainnet by the esteemed developer Casey Rodarmor in January 2023, Ordinals represents a groundbreaking approach to the creation of token economies on the Bitcoin network: data like text, image, video, and more is added or "inscribed" onto a Satoshi, which exists as a digital artifact on the blockchain. Ordinal Inscriptions don't need smart contracts to operate, therefore offering users unmatched flexibility regarding token creation by inscribing arbitrary data into the Bitcoin blockchain and encoding it into the witness field of transactions. It's a more secure, permissionless way to create NFTs, which can be transferred/sold to another party via online platforms or marketplaces that support NFT trading.
