Workflow History Signing, Propagation, and Attestation let you prove what happened in distributed systems and AI agents—replacing audit logs with tamper-evident cryptographic chains using SPIFFE identities.
July 1, 2026
Summary
When AI agents make business decisions or access sensitive data, you now have verifiable proof of who did what and whether execution history was altered—critical for compliance and downstream system trust in regulated industries.

Implementation verdict
Ready now as open-source Dapr 1.18 or managed Catalyst Cloud. Replaces manual audit trails with built-in cryptographic signing. Requires SPIFFE-compatible identity infrastructure and downstream systems that can validate attestations. Worth evaluating immediately if you run long-running workflows or agentic systems in regulated domains.
