OPAQUE gives away the agent audit receipt and sells the machine that prints it
The Linux Foundation now hosts TRACE, a format for evidence of what an AI agent actually did. The package that produces those records still ships as a developer preview.
The Engineer · Build desk
What happened
- The Linux Foundation said on August 25 it had accepted TRACE, an open specification for AI runtime evidence contributed by OPAQUE.
- A TRACE Trust Record is a portable artifact signed inside a trusted execution environment, binding runtime, software, policy, data classification and tool usage together.
- OPAQUE is releasing the format for free while selling the confidential runtime and governance software that enforces policy and emits the records.
- The project remains a developer preview, with governance and verification work described as unfinished.
Why it matters
- capability Because the format wraps attestation and provenance specs that clouds and chip vendors already produce, an auditor could in principle read one operator's evidence without buying that operator's stack.
- cost The receipt is free and the machinery to produce it is not, so the spend lands on enterprises that need runtimes capable of enforcing policy and signing the output.
- decision Compliance teams have to choose between writing TRACE into controls now and waiting for verifier governance, because a record nobody is chartered to validate proves little in a dispute.
- constraint The download count cannot carry procurement weight, which leaves buyers without a public measure of who is actually running this in production.
The commercial logic here is legible without any help from the press release. A signed record is only worth something if a party that did not run the workload can check it, and checking needs a verifier, a trust anchor, and rules about who may issue and revoke. OPAQUE contributed the format; according to the source, the project's own documents show governance and verification work is unfinished [5], with the technical track moving to the Coalition for Secure AI [3]. Until that settles, a Trust Record is a well-formed artifact whose validation path is a matter of trust in whoever produced it.
What makes the format plausible is that it is mostly an envelope. TRACE composes existing specifications, including RATS, EAT, SLSA, SCITT, SPIFFE and EAR [6], so the underlying attestations, provenance statements and workload identities are things cloud platforms, chip vendors and policy engines already emit. That is the argument for cross-vendor uptake: no cloud or agent framework has to adopt a competitor's definition of proof to interoperate [17]. It is also why the interesting design question is not the schema but the verifier.
The adoption figure deserves less weight than its size suggests. Nearly 135,000 PyPI downloads in the ten weeks after the June debut [7] works out to roughly 13,500 a week [14], which is the shape of continuous integration traffic and casual evaluation as much as deployment. The Linux Foundation itself labels it a company-reported package count rather than evidence of production use [7], and the package identifies TRACE as a developer preview [8]. Anyone writing "TRACE record" into a control framework this quarter is designing an audit around preview software.
The lineage is more informative than the download chart. Imran Siddique built Microsoft's Agent Governance Toolkit for agent identity, permissions and runtime behavior before joining OPAQUE [9]; TRACE pushes the same concerns into an after-the-fact artifact that names the model, the location, the active policy, the class of data touched and the tools called [10]. That is the correct list of fields for an incident review. It is also, conveniently, the list of things you can only capture if you control the runtime, which is the product OPAQUE sells [4].
One detail worth holding onto: Intel co-developed TRACE with AMD, Microsoft and the Technology Innovation Institute [3], and Intel Capital took part in the $24 million Series B that valued OPAQUE at about $300 million post-money [11]. The same company sits on the standards side and the cap table [15]. That is normal in confidential computing, where the hardware root of trust and the vendor ecosystem are the same small set of names, but it is a reason to read the verifier rules closely rather than to treat neutral hosting as neutrality already achieved.
The test of whether this is a standard or a product feature with a foundation logo is narrow and checkable: a Trust Record emitted by a runtime OPAQUE did not build, validated by a party that sells neither.
What to watch
- The finished technical charter: who may operate or certify a verifier, and who holds maintainer authority once the Coalition for Secure AI owns the technical work.
- A Trust Record produced by a runtime OPAQUE did not build and validated by an unrelated third party.
- Any audit or compliance framework citing TRACE while the package still ships as a developer preview.

Claim ledger
Ranked by verification strength, evidence, and original report placement.
- [1]
The TRACE documentation describes a Trust Record as a portable artifact signed inside a trusted execution environment that binds the runtime environment, software, policies, data classifications and tool usage, and is intended to travel across clouds and confidential-computing environments.
- [2]
The Linux Foundation announced on August 25 that it had accepted TRACE, short for Trust, Runtime Attestation and Compliance Evidence, as an open specification contributed by OPAQUE.
- [3]
TRACE was developed with AMD, Intel, Microsoft and the Technology Innovation Institute; the Linux Foundation will provide a vendor-neutral home while technical work runs through the Coalition for Secure AI.
- [4]
OPAQUE is giving away the evidence format while selling the infrastructure that enforces policies and produces the evidence, building confidential runtime and governance software aimed at that job.
- [5]
TRACE is still a developer preview with unfinished governance and verification work, and the project documents show the handoff to neutral governance is not complete.
- [6]
The Linux Foundation says TRACE builds on existing standards including RATS, EAT, SLSA, SCITT, SPIFFE and EAR to create a common evidence layer.
- [7]
The Linux Foundation said TRACE recorded nearly 135,000 PyPI downloads in the 10 weeks after its introduction at the Confidential Computing Summit in June; the article notes this is a company-reported package count rather than evidence of production adoption.
- [9]
Imran Siddique, OPAQUE's chief platform officer, joined the company in 2026 after more than 15 years at Microsoft, where he created the Agent Governance Toolkit, an open-source framework for controlling agent identity, permissions and runtime behavior.
- [10]
TRACE extends that work into evidence: a signed record intended to show which model ran, where it ran, which policy was active, what class of data it touched and which tools it called.
- [11]
In February OPAQUE announced a $24 million Series B led by Walden Catalyst with Intel Capital, Race Capital, Storm Ventures, Thomvest and the Advanced Technology Research Council participating, bringing total funding to $55.5 million at about a $300 million post-money valuation.
- [12]
The open specification, technical documentation and reference implementations are available through the TRACE project site and on GitHub, according to the Linux Foundation announcement.
- [13]
The question TRACE is meant to answer is how anyone outside an agent's operator can verify what actually ran when the agent touches sensitive data or calls a tool.
- [14]
Nearly 135,000 downloads across 10 weeks averages roughly 13,500 downloads per week.
- [15]
Intel appears on both sides of the TRACE arrangement: it co-developed the specification and its venture arm, Intel Capital, participated in OPAQUE's Series B.
- [16]
If TRACE becomes a common receipt for agent activity, enterprises will need infrastructure capable of enforcing policies and producing those receipts.
- [17]
A shared evidence format could let existing security products, cloud attestations and policy engines exchange records without requiring every cloud, chipmaker or agent framework to accept another vendor's proprietary definition of proof.
