Ordinals brings inscriptions to Bitcoin

Casey Rodarmor released the Ordinals protocol and tooling for tracking individual satoshis and attaching inscriptions to them.

Inscriptions place content in Taproot witness data and identify the resulting satoshi through an off-chain numbering convention. The protocol required no Bitcoin consensus change, but it produced new demand for block space and renewed debate over transaction policy.
