The BTCO DID Method specification defines a decentralized identifier method that leverages Bitcoin Ordinal Theory and Inscriptions to create, resolve, update and deactivate DIDs directly on the Bitcoin blockchain.

The BTCO DID Linked Resources extension provides a standardized framework for associating immutable resources with DIDs through Bitcoin Ordinal inscriptions, enabling verifiable credential schemas, governance frameworks, and other resource types.

The BTCO Verifiable Metadata specification defines how to create and verify metadata about Bitcoin Ordinal inscriptions using the W3C Verifiable Credentials Data Model 2.0, enabling trustless verification of inscription properties and collection curation.
