Epistemic State Replication Proposed for Agentic Distributed Systems.

A new paradigm for distributed systems, Epistemic State Replication (ESR), is proposed to address the unique challenges posed by agentic AI systems. Traditional State Machine Replication (SMR) relies on bitwise identical states across replicas, which becomes problematic when dealing with autonomous, stochastic, and generative AI agents. These agents might arrive at semantically equivalent operational decisions through divergent reasoning paths or different token boundaries, making bitwise agreement inefficient and restrictive. ESR shifts the focus from data visibility to knowledge visibility, aiming for replicas to agree on "belief" rather than exact "bits." The framework formalizes an epistemic node state, separating a deterministic evidence log from an evolving, stochastic belief lineage. It introduces concepts like Semantic Linearizability, ensuring operations reflect the latest committed operational meaning within defined semantic compatibility, and Bounded Eventual Coherence, which limits semantic divergence. ESR also outlines protocols for propagating insights using structured epistemic deltas and enables Verifiable Semantic Rollbacks to correct faulty premises without losing context.
