Decentralized Resource Name (DRN) DID Method

This document specifies the did:drn Decentralized Identifier (DID) method, which defines a deterministic mapping from Uniform Resource Names (URNs) (RFC 8141) into a DID-compatible identifier format called a Decentralized Resource Name (DRN). The did:drn method preserves URN semantics, enables DID resolution without mandatory centralized infrastructure, and provides optional cryptographic and service-layer extensibility. The method is fully compatible with the W3C DID Core specification (W3C DID Core, 2022) and the broader DID ecosystem.
