Live demo · Side-by-side narrative for non-technical viewers

A compliance check, without the data behind it.

Watch a zero-knowledge proof generated in the browser, verified, and anchored on-chain in real time. The technical flow runs on the left. The plain-English explanation tracks on the right — written for a CCO, GC, or partner who doesn't need the math, only the consequences.

For non-technical viewers

What you're about to see

Stage 0 of 5 · Idle

Pick a scenario on the left — bank KYC, age verification, AML screening, or accredited investor — then press Run demo. Five stages will run in real time.

The technical flow runs on the left. This panel explains what just happened in plain English, step by step. By the end, you'll have watched a complete compliance check happen — and you'll see exactly what data was retained: none.

The whole point

A standard compliance check today produces a customer file you have to keep. This demo produces a mathematically verified attestation — and nothing else. Same audit trail, no data liability.

What's running

This demo uses production primitives — Noir / UltraHONK ZK circuits compiled to WASM, Barretenberg backend, and a deployed Solidity contract on Base Sepolia at 0xCB9567…4c3264. The bundles you can inspect are real, generated 2026-04-23 from live circuits.

What changes by scenario

The circuit changes — proving age > 18 versus sanctions-clean versus accredited. The protocol doesn't. The same four-layer stack produces the same attestation format for every regulated check.
