Don’t just store your data. Prove it.
Verifiable Data issues portable proofsabout your data that anyone can check — without your data, and without our software.Turn “trust us” into “verify it yourself.”
- 4 proofs
- exactness, deletion, clean-room, unlearning
- free
- verifying is always free — no account needed
- portable
- a small certificate anyone can check in seconds
- per-proof
- billed per artifact, not per byte — additive line
Every data-trust claim today ends in “trust us.” Trust that the archive still decodes. Trust that the deleted record is really gone. Trust that the clean room didn’t peek. Trust that the model forgot.Verifiable Data replaces the promise with a proof — four of them, each a portable certificate a third party verifies in seconds. Issuing is metered; verifying is always free and needs no account.
Prove a compressed archive decompresses to exactly the data you committed to — checked by re-decoding a handful of random blocks against a signed root, never the whole dataset.
For: archival integrity, data escrow, “is this the file we agreed on?”
Keep a WORM-immutable, tamper-evident store and honour GDPR/CCPA erasure. The bytes never change; the ability to read a subject’s data is provably destroyed, and the destruction is itself an immutable, certified event.
For: right-to-erasure on immutable / audited storage.
Run exact aggregates (SUM, COUNT, averages) across parties where the operator provably cannot see any raw row — non-visibility is a mathematical property, not a policy promise.
For: cross-party analytics, data collaborations, privacy-first measurement.
ExploreProve your AI forgot a specific subject — that the updated model is exactly what training-without-them yields, and that they influenced nothing else.
For: ML compliance, “prove the model no longer contains my data.”
How verification works
at1 prove seal data.at1 -o proof.at1proof # issue a proof (metered) # hand the recipient ONLY proof.at1proof -- never your data at1 prove check proof.at1proof # anyone verifies -- FREE, no account -> VERIFIED: decompresses to exactly the committed data
You issue a proof with one command and hand the recipient only the certificate. They run one free command and get a yes/no — reading none of your data and running none of our proprietary software. That’s the whole product: proofs that travel, checkable by anyone.
Pricing
Billed per proof issued— a proof is a compliance deliverable, so it’s priced per artifact, not per byte. Your first 1,000 proofs are free — a one-time credit— and verifying is always free. Volume rates below are per month. Your compression bill is unaffected; this is a separate, additive line.
