Show HN: ZK Visualizer – I built this while learning zero-knowledge proofs
zkenthusiast Thursday, January 29, 2026I was learning ZK proofs and found that visualizing things really helped me understand them. Noticed there aren't many interactive visualizations out there, so I built one.
Here's the first version: zkvisualizer.com
It walks through the full pipeline step by step (Problem → Circuit → R1CS → Polynomials → Witness → Proof → Verification) with real Groth16 proofs generated in your browser using snarkjs.
You can toggle between what the prover knows vs what the verifier sees, and there's a tamper detection demo where you can watch verification fail.
This is still very early on, but I would be very happy to receive any feedback!
Summary
The article provides an overview of the ZK Visualizer, a tool that helps users understand and analyze zero-knowledge (ZK) proofs. The ZK Visualizer allows users to interactively explore the structure and performance of various ZK proof systems, assisting developers and researchers in understanding the underlying technology.
