The industry standard zk-SNARK for constant-size proofs and lightning-fast verification on Ethereum.

Groth16 remains the most widely deployed zero-knowledge proof system in production (powering protocols like Zcash and Tornado Cash). It generates compact proofs of just 128 bytes regardless of circuit complexity, making it the premier choice for gas-efficient on-chain verification. While it requires a per-circuit trusted setup (the powers-of-tau ceremony), the performance trade-off is unmatched: verification takes less than 1ms on standard hardware. It is the definitive benchmark for pairing-based SNARKs using the BLS12-381 curve.

### [Generating zk-Proofs from Browser Interactions Using Claude Vision](https://nyc.aitinkerers.org/talks/rsvp_Nm7EH_v3HOE)

Learn how AI vision models generate zero-knowledge proofs (zk-proofs) from browser interactions without exposing sensitive data. We’ll demonstrate how our system observes user actions within a secure webview to create zk-proofs for credential verification and compliance monitoring. We’ll also explore the challenges we faced in building this technology, from ensuring user privacy to overcoming technical hurdles. Discover how advancements in AI and cryptography enable secure, private verification.
