Lucid Computing
A company offering attested, confidential-computing AI clusters; it hosts the Sovereignty Certificates location specification and runs a verification research programme.
Lucid Computing describes its offering as "Verifiable AI. Proven in hardware.": privacy-preserving, verifiable compute clusters built on trusted execution environments 1. Its verification work includes:
- Location certificates. Lucid hosts, in its GitHub organization, the draft Sovereignty Certificates specification, which packages ping-based chip location verification as short-lived certificates 2; its homepage links to the effort 1. See Lucid sovereignty (location) certificates.
- Developer platform. Its documentation lists a "Data Sovereignty & Localization" auditor, described as "Ensuring data remains within approved geographic jurisdictions" 3.
- Traffic shaping. A Lucid design brief proposes capping the external traffic of each pod of accelerators, on the grounds that inference sends little external traffic while training moves large volumes between machines 4. The brief says the design is not yet implemented or red-teamed 4. See Bandwidth limits and compartmentalization.
- Research cluster. Lucid reports that it builds and operates a bare-metal GPU research cluster on behalf of the Verifiable Compute Foundation, which decides who gets access 5 6. Its cluster page says the cluster opens to the community in November 6.
- Red-teaming and standards. Lucid reports running red-teaming programmes with national security agencies and government research institutes, in which the teams attacking its architecture are not the teams that built it 5. It reports building a testbed inside an unnamed government-funded research institute, whose first configuration retrofits two eight-GPU H100 servers to test claims about where compute runs, how it is used and which model is loaded 7. Lucid says the institute sets the test plan 7. It lists standards in development for compute identity, attested audits and hardware-rooted compute accounting 5.

Implementations
Implementations this organization develops.
- A draft specification, hosted by Lucid Computing, for short-lived certificates that bound where a workload runs by timing signed exchanges with fixed anchors.
Related records
Mechanisms and implementations whose records cite or describe this organization's work.
- Capping or removing network links between groups of accelerators, so that serving within each group still works but large training across groups becomes far slower.
- Timing a chip's signed replies to trusted servers at known places, so that the speed of light bounds how far away the chip can be.
