01 · FIX THE DATASET
Commit before selecting
The seller processes the CSV locally and registers its cryptographic commitment.
PRIVATE DATASET SAMPLING
Inspect the sample.
Verify where it came from.
The seller fixes the dataset first. Records are selected afterwards. You verify that the disclosed records belong to the committed dataset.
Start verificationSee how it works5 USDC per verification. No accounts. No subscription. Your full CSV stays on your device.
02 · SELECT ONCE
No hand-picked sample
After the verification fee is confirmed, the buyer requests one fixed random selection.
03 · VERIFY LOCALLY
Check the disclosed records
The buyer checks the sample file and inclusion proofs in their own browser.
Know what a proof does — and does not — prove
An inclusion proof links disclosed records to the seller’s prior commitment. It does not certify data quality, lawful sourcing, ownership or the seller’s identity. DataPeek does not hold the purchase price of a dataset.
