Resilience Architecture

Redundancy and Availability

• Geo-Distributed Validators: Minimum 3 regions per cluster (NA, EU, APAC) ensure continuous consensus during outages.

• Fault Isolation: Agents queue proofs locally if disconnected; automatic back-pressure control avoids loss.

• Hot/Cold Failover: The Lattice AI Core uses active-active redundancy with a 30 s RTO.

Byzantine Fault Tolerance

Secure Lattice’s validation layer follows a variant of Practical Byzantine Fault Tolerance (PBFT). Even if 1/3 of validators act maliciously or go offline, consensus and proof continuity persist.

Simplified model:

if len(signatures_from_validators) >= (2/3 * total_validators):
    finalize_proof(batch_id)

This ensures no single compromised node can rewrite or censor proof entries.

Disaster Recovery

• Event Journals: Each agent maintains a ring-buffer (30 MB default) of unsynced telemetry, encrypted locally.

• Recovery Mode: In the event of outage, agents re-establish sessions and re-anchor unsent proofs with preserved timestamps.

• Chain Forks: Use checkpointing with Merkle roots signed by ⅔ quorum to avoid state rollback.
