The problem

Data now flows between blockchains, databases and AI agents. Nobody can check that it's real.

Incoming dataLive

Blockchain via indexerWallet balanceNo proof

Bad actor

Your appUnchecked

Wallet balance

5730USDC

Read from the chain via an indexer

Your app reads a balance. 5730 USDC, from the chain through an indexer, like most apps do.

Then someone gets in between. An indexer, an API, a compromised server. They can send your app any number they like.

Your app can't tell which is real. So it acts on the forgery: payouts and reports built on a number nobody checked, wherever data moves between blockchains, databases and AI agents.

Provably attaches a proof to every answer. The swapped number fails its check. The real one is shown, verified in milliseconds.

What you get

Data that proves itself. Wherever it goes, whoever reads it.

FAQ

Questions, answered. And anything else, just ask.

They prove to partners and remote systems that your data and query results are correct. Each proof covers where the data came from, how it changed and that the query ran correctly: cryptographic guarantees instead of assumptions. So you can work with people you don't fully trust without contracts or manual audits.
