The paper introduces Epistemic Byzantine Fault Tolerance (EBFT), a fault-tolerance model for agentic infrastructure. It defines the Honest Quorum Problem: protocol-compliant agents can still endorse semantically invalid transitions due to correlated reasoning errors from shared model weights, training data, or prompts. EBFT augments the Byzantine fault bound with confidence-indexed quantities for semantic safety and liveness, and derives quorum-threshold conditions for validity and agreement.

Formalizes a specific failure mode in multi-agent consensus — correlated reasoning errors when validators share model provenance. Useful input for anyone designing quorum-based agentic infrastructure, beyond protocol compliance.
