What is Ordinals on BTC?
Ordinals on the Bitcoin network are similar to NFTs on the Ethereum network. They were created in January 2023, and over 600,000 had been minted by May 2023.
The ordinals protocol enables people who run Bitcoin nodes to inscribe data on the blockchain. That data can include smart contracts that can host an image. This process is similar to how NFTs are hosted on Ethereum, but not exactly the same.
