Architecture Overview

The Libertaria Stack is organized into five protocol layers (L0-L4+), each with a specific purpose and clean interfaces to adjacent layers.

Layer Philosophy

Each layer follows these principles:

  1. Orthogonality: Use layers independently or together
  2. Kenya Rule: Every layer runs on minimal hardware
  3. Exit-First: Fork or exit at any layer without penalty
  4. No Blockchain: Sovereignty through cryptography, not consensus

Cross-Cutting Concerns

Security

  • Cryptographic Stack: SHA3/SHAKE, Ed25519, X25519, ML-KEM-768
  • Post-Quantum: Hybrid PQXDH handshakes by default
  • Memory Safety: Zig's safety features + explicit zeroization

Performance

  • Zero-Copy: Hot paths avoid allocations
  • Lock-Free: Shared-nothing architecture where possible
  • Kenya Compliance: All targets under strict resource budgets

Privacy

  • Unlinkability: Context-separated identities
  • Metadata Protection: MIMIC skins resist traffic analysis
  • Local-First: Data stays on device unless explicitly shared

Layer Interactions

L4 Application    →  "Store this event"
                    ↓
L3 Governance     →  "Authorize per Chapter policy"
                    ↓
L2 Session        →  "Send to peer via active session"
                    ↓
L1 Identity       →  "Sign with SoulKey, check QVL trust"
                    ↓
L0 Transport      →  "Encrypt, wrap in MIMIC skin, send"
