- Abstract: Sybil resistance reframed as four-layer composition (nullifier, proof-of-cost, QVL trust graph, behavioral admission), not nullifier-centric. - New section 1.5 Scope of This Paper: identity layer only; KEF consensus, settlement, currency, governance, dispute resolution are companion specs. - Section 3.1: Archival Observer adversary (A_arc) — harvest-now-decrypt-later, cited to Babbush-Zalcman-Gidney et al. 2026 quantum resource estimates. - Section 3.2: G6 Retroactive Unforgeability security goal — forces activation deadline discipline (T_act must precede T_crqc or G6 is unattainable). - Section 4.2: DnakeyProfile table (inclusive / standard / sovereign) with Argon2id parameter sets; citizenship-tier-driven, not hardware-class. - Section 4.4: migration-artifact DID carve-out removed. Footnote rewritten and the pre-Phase-5 zeroed-pk paragraph replaced with canonical-from-genesis requirement. DIDs committing to zeroed pk_MLDSA are no longer permitted. - Section 5.2: Option C (deterministic re-keygen) named as normative Lattice HD instantiation. Lyubashevsky authorship provenance footnote added. Proofs-team verification acknowledged as gating concrete ratification. - Section 5.7 and Conclusion: 'PQ from genesis' softened to 'PQ at the root and KEM from genesis; SoulKey signature hybridization on deadline-bounded path'. Cross-reference to SPEC-040 v0.2.0 section 10 for implementation supply chain (liboqs during Phase 1, pure-Zig before sovereign Phase 2). - Section 9.5 Future Work: KEF (Key Event Framework) consensus specification explicitly deferred — equivocation detection, fork-choice, Byzantine witness thresholds, partition recovery. SPEC-KEF as companion doctrine. - references.bib: Babbush-Zalcman-Gidney et al. 2026 whitepaper entry (Google Quantum AI + Ethereum Foundation + Stanford, dated 2026-03-30). - PDF rebuilt: 35 pages, 713 KB. pdflatex + bibtex + pdflatex twice. |

SKH: Anonymous Root Keys for Quantum-Safe Decentralized Identity
A three-tier hierarchical identity architecture combining post-quantum key exchange, context-separated identities, Sybil resistance, and anonymous root keys -- without blockchain dependency.
Structure
arxiv/ LaTeX source + bibliography for the arXiv preprint
bench/ Benchmark harness (Zig) and comparative benchmarks (Python)
easycrypt/ EasyCrypt formal proofs (HKDF, hybrid sig, KEM)
tamarin/ Tamarin Prover protocol security model
Build
cd arxiv
pdflatex skh-arxiv-v1 && bibtex skh-arxiv-v1 && pdflatex skh-arxiv-v1 && pdflatex skh-arxiv-v1
Reproduce Benchmarks
See bench/README.md.
Reference Implementation
The SKH cryptographic core (Zig) and application layer (Janus) are part of the Libertaria identity stack.
