The Locus URI Scheme: A 256-bit Interplanetary Addressing and Resolution Framework

This document defines the "locus" URI scheme, a hierarchical interplanetary addressing system that encodes both astronomical location and network routing information within a fixed 256-bit structure. The scheme enables deterministic resolution of named endpoints into IPv6-compatible network addresses and supports future interplanetary networking without reliance on centralized lookup systems. The Locus scheme introduces a unified address format spanning five tiers: star system, orbital position, planetary body, network domain, and host identifier. The upper 128 bits encode astronomical location; the lower 128 bits encode IPv6-compatible network identity. For present Earth-based deployments, the scheme resolves to standard HTTPS URLs via DNS. Future extensions accommodate delay-tolerant networking across Lunar, Martian, and interstellar distances.
