Core Architecture
Understanding the HUMΛN Protocol's layered design
Architecture Philosophy
HUMΛN is built on a five-layer architecture that separates concerns while enabling seamless integration. Each layer has a specific purpose, and together they form a complete protocol for Human-AI Orchestration.
Think of it like the internet: TCP/IP provides the foundation, HTTP builds on top, and applications use both.HUMΛN follows the same principle — composable layers that work independently but shine together.
The Five-Layer Stack
Application Layer
Your agents, workflows, and business logic. This is where you build.
Orchestration Layer (HumanOS)
Coordinate multi-agent workflows, route tasks, and enforce human-in-the-loop.
Capability Layer (Capability Graph)
Skills & permissions. Grant, verify, and revoke capabilities across agents.
Identity Layer (Passport)
Cryptographic identity for humans, orgs, and agents. DID, keys, metadata.
Ledger Layer (Provenance)
Immutable audit trail. Every action is logged with full provenance.
Key Architectural Principles
Separation of Concerns
Each layer has a single responsibility. Identity doesn't know about orchestration. Capabilities don't know about the ledger. This makes the system modular and testable.
Composability
Use only what you need. Want just identity? Use Passport. Need orchestration? Add HumanOS. The layers compose cleanly.
Immutable Provenance
Everything flows through the ledger. Every action, delegation, capability grant — all logged immutably. This is non-negotiable in HUMΛN.
