What Datavar is

Your data already trains AI models. It gets scraped, bought and resold, and none of the money reaches you.

Datavar is a data protocol where you contribute data on your own terms and get paid when it is used. Every dataset carries a consent receipt held on the Stellar ledger: who allowed it, for which buyer, for what purpose, and until when. An AI team can check that receipt without asking us, and you can withdraw it without asking anyone.

Four steps

1. Sign in with a Stellar wallet. No email, no password, no name.
2. Upload a dataset. It is hashed on your device before anything leaves it.
3. Grant consent to a named buyer, for a named purpose, until an end date. Your wallet signs it.
4. When it sells, your earnings are credited to you in a contract, and you claim them in XLM with your own signature.

How this differs from a data broker

A data broker sells data you never knowingly handed over and keeps the proceeds. A privacy setting stops the collection and pays you nothing.

On Datavar the terms are recorded on a public ledger. Consent always has an end date and only you can revoke it, and the contract enforces both rules.

Payments are handled the same way. Your earnings are credited to your wallet in a payout contract, and only your signature moves them out. We can record whom the money in the contract belongs to, but we cannot pay it to ourselves, move it back out, or stop you claiming it.

Datavar runs on Stellar testnet today. The consent and payout contracts are deployed on-chain. Buyers are simulated while the demand side is built, so payouts settle in test XLM. A third contract, for licences with a hold period, a protocol fee and refunds on early withdrawal, is written and tested but not deployed yet.

How it works goes through each step, from wallet to payout hash.
