What is zkRune?
zkRune is a visual Zero-Knowledge Proof builder that makes privacy-preserving technology accessible to everyone - no cryptography expertise required.
Prove facts without revealing sensitive data:
• Age Verification: Prove you're 18+ without showing your birth date
• Balance Proof: Prove sufficient funds without exposing your exact amount
• Anonymous Voting: Cast votes with verifiable results while maintaining voter privacy
• Private Membership: Verify group membership without revealing your identity
• Range Proofs: Prove a value falls within a range without disclosing the actual number
How it works:
zkRune uses real Groth16 zk-SNARKs (the same cryptography securing major blockchains) but makes them simple. Our visual circuit builder lets you create custom privacy proofs through drag-and-drop - no coding, no command line, no servers.
Key features:
• 100% Client-Side: All cryptographic operations run in your browser. Your private data never leaves your device.
• Works Offline: Install as a PWA on your phone. Generate proofs on airplane mode.
• No Setup Required: No wallets, no accounts, no API keys. Just visit and use.
• Real Cryptography: Not simulations - mathematically verifiable zero-knowledge proofs.
• Open Source: Fully transparent and auditable code.
Perfect for:
Developers building privacy features, organizations needing compliance without data exposure, and anyone who values digital privacy.
Built for the Zcash ecosystem
