Linux Foundation Adds TRACE Spec for AI Runtime Evidence

The Linux Foundation has accepted TRACE, an open specification for hardware attested runtime and compliance evidence for AI agents and confidential workloads, from OPAQUE, the group announced in a press release. TRACE was developed with AMD, Intel, Microsoft, OPAQUE, and the Technology Innovation Institute.

TRACE creates a common evidence layer for records that connect the runtime environment, software, policies, data classifications, and tool use into a portable cryptographically verifiable artifact. The specification is designed for AI agents and confidential workloads across cloud and confidential computing environments.

TRACE builds on existing standards including RATS, EAT, SLSA, SCITT, SPIFFE, and EAR. Its initial specification focuses on current AI agent architectures and confidential computing deployments.

TRACE recorded nearly 135,000 PyPI downloads within 10 weeks of its initial introduction at the Confidential Computing Summit in June 2026. The open specification, technical documentation, and reference implementations are available at trace.agentrust-io.com and on GitHub.
