zkRune

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.
