Hi Flower team,

I built Sovereign Mohawk, a formally verified hierarchical FL runtime that scales to 10 M nodes with 55.5% Byzantine tolerance (far beyond standard Krum or median-based defenses).

It uses a 4-tier tree (edge → regional → continental → global) + zk-SNARK verifiable aggregation + O(d log n) streaming gradients.

Formal proofs (six theorems):

Key theorems excerpt:

Sovereign Mohawk is formally verified across six theorems (full details in ACADEMIC_PAPER.md + proofs/):

Theorem 1 (BFT): (∑ f_t)-Byzantine resilient if f_t < n_t/2 per tier → 55.5% global tolerance (5.5 M malicious nodes out of 10 M) via hierarchical Multi-Krum.

Theorem 2 (Privacy): Sequential RDP composition → strict ε=2.0 budget across entire population.

Theorem 3 (Comms): O(d log n) complexity (40 TB → 28 MB at 10 M nodes).

Theorem 4 (Stragglers): 99.99% success probability with 10× redundancy.

Theorem 5 (zk-SNARKs): 200-byte proofs, O(1) verification in ~10 ms.

Theorem 6 (Non-IID): Convergence rate O(1/√(KT)) + O(ζ²) under heterogeneity bound ζ².

Test suites & numbers:

Test suites (all public, Apache 2.0):

1. Core runtime (Go): make test && make verify
2. Python SDK: make test-python-sdk (includes proof verification benchmarks)
3. Full genesis swarm: ./genesis-launch.sh → spins up 200-node local testnet + Grafana in <60 s
4. Scale validation: 5000-node Kubernetes manifests + 200-node audit (results in audit_results/20260219)

Key results (March 2026):

• zk-SNARK verification: 10.55 ms mean, 94.77 ops/s
• Aggregation: 30.63 µs mean
• Gradient compression: 995 µs mean
• Weight integrity: error < 1e⁻⁷ after sharded FedAvg
