Ord.io

Launched in March 2023, Ord.io has led several initiatives in the Ordinals ecosystem: "Startibutes," a standard for indexing categories of rare sats; "Social Inscriptions," enabling users to interact with inscriptions through profiles, upvotes, and replies; and "Inscription Number Immutability," embracing inscription numbers as permanent identifiers. It lets users search, browse and interact with Ordinals inscriptions on the Bitcoin blockchain and intends to use the fresh capital to expand support for the upcoming Runes protocol, a new fungible token standard for Bitcoin launching at the halving.
