MemTX: A Transactional Protocol for Reliable Agent Memory
MemTX, a newly developed protocol, tackles the issue of unreliable shared memory in LLM agent systems. Existing memory frameworks treat every accepted write as an immediate truth, which can result in irreversible actions due to outdated or corrupted data. This innovative protocol employs a transactional belief-commit system, ensuring each record is accompanied by evidence, permissions, provenance, and validity. Writes occur within snapshot-isolated transactions and are processed through a validate-and-commit pipeline. Irreversible tool calls depend on the current belief state, and retracting a belief initiates a structured cascading repair of related records and tool effects. Two key invariants—action-safety gating and cascade-repair completeness—are verified through property-based testing. This research is available on arXiv, ID 2607.23929.
