Voltry · Verify and certify used GPU clusters

What Voltry does

Verify, test, and certify used GPU clusters before you buy or deploy.

Independent assurance

Independent diagnostic auditing and performance certification for used GPU clusters.

A permanent record

We measure the physical condition of used GPUs and bind it to a permanent, tamper-evident record.

Hidden hardware risk

Protecting your AI infrastructure investment from hidden hardware flaws.

The independent condition and provenance standard for used AI compute.

Verify a certificate Get your fleet certified

Independent, tamper-evident, and never priced.

Draft specimen, not for reliance. No opinion of value is expressed.

The problem

The serial number is not yet a condition record.

A datacenter GPU already exposes identity, configuration, error, repair, thermal, power, utilization, and event data. Those facts rarely cross organizational boundaries in a standardized, policy-bound, independently verifiable form.

Signed field bundles

C0/A0 evidence bundles banked by Voltry's field program as of the VCM-1 v0.3 maturity statement.

40+

Registry identities

Software-reported A0 identities across the field program; physical-silicon continuity is not independently established at A0.

Sensor characterizations

Banked across four device models, measuring reported-value cadence and internal energy-signal consistency.

Evidence classes

Four evidence classes, kept separate.

A value is not meaningful until its evidence class is known. Voltry keeps hardware reads, replayable calculations, statistical estimates, and party assertions separate. Modeled evidence remains decision-inert in VCM-1 v0.3.

MEASURED

A fact read from hardware or an authoritative device interface.

Model, UUID, serial, and PCI topology
Driver, VBIOS, and InfoROM state
ECC, row-remap, and retirement state
Thermal, power, energy, clock, and utilization reads
PCIe, interconnect, configuration, and vendor events

The record includes the source and capture context.

DERIVED

A deterministic function that another party can replay.

Duty odometer and incident rates
Coverage and threshold distance
Seven non-compensatory axes

Inputs, formula version, and output travel together.

MODELED

A statistical estimate with its uncertainty and calibration stamp.

Always presented as a band
Never used to determine a VCM-1 grade
Explicitly marked when calibration is pending

Modeled evidence is labeled and remains outside VCM-1 grades.

DECLARED

A party-signed assertion, attributed to the party making it.

Ownership and custody
Facility assignment
Reservation and configuration intent

A declaration is verified as signed, not promoted to a measurement.

Certificate properties

Five properties of every record.

SEMANTICS

Every claim names what it is

Measured, derived, modeled, and declared evidence stay visibly distinct. A reader can see the source and the trust boundary before interpreting a result.

ASSURANCE

Evidence states its assurance level

A0 through A3 state how strongly evidence is bound to the physical device, from host-signed self-report through platform binding and independent witness.

COVERAGE

A scan is not a history

C0, C1, and C2 say whether the record is a point-in-time scan, functional observation, or continuous history. Coverage is never inferred from a good-looking result.

REFUSAL

Absence is never a pass

Missing evidence produces Not Assessed, not a favorable guess. Once VGR-1 publishes, a missing required axis produces UNGRADED rather than dropping out of the minimum.

REPLAY

The result can be independently rebuilt

A retained verification package lets a third party check integrity, provenance, and the derivations VCM-1 and its versioned artifacts specify.

From monitoring to portable evidence

A record counterparties can retain and verify.

Operator-plane monitoring produces useful signal for the operator. Voltry's category is different: selected evidence made portable, policy-bound, and independently verifiable by an external counterparty, with the residual trust boundary stated on the record.

01

Trust
Attestation
Schedules, periodic reports, and party assertions remain useful inputs, but they do not bind a claim to the device or make it independently replayable.
02

Telemetry
Raw signal
Vendor and operator tooling can monitor fleet health. It is designed for the operator plane, not as a portable counterparty record.
03

A portable record
Certified record
Classified evidence, explicit assurance and coverage, canonical signatures, and ledger proofs that a relying party can retain and verify.
- Identity strength stated on the face
- Missing evidence remains visible
- Specified derivations are replayable
- Tamper-evident history

Summary

Voltry is an evidence pipeline: read-only capture, canonical signed records, an append-only registry with a transparency ledger, deterministic evaluation, and audience-scoped views.
