01The Problem

Blockchains made activity verifiable. They also made too much of it visible.

Your financial activity, identity, and on-chain behavior shouldn't have to be public to be trusted. Transparency became surveillance — every transaction exposes sender, recipient, amount, and history.

Without ZeroKnow

Public on-chain data

  • Transaction history0x3a...f72e
  • Identity0x9b...c4d1
  • Positions12 tokens
  • CounterpartiesVisible

With ZeroKnow

Prove the fact, hide the data.

02How It Works

From private state to public trust.

Prove what matters without revealing the underlying data. ZeroKnow separates information from proof: private data becomes a claim, and only the claim is published.

07Redaction by Default

Information disappears. Certainty remains.

Run your cursor over the data. The values vanish — the verified claim does not. That is the entire idea behind ZeroKnow.
