classu.cash

Lightweight demo site explaining Cashu (privacy-preserving digital cash using blind signatures).

This repository contains a small Next.js demo app that visualizes the three main phases of a Cashu token lifecycle: Minting, Transfer, and Redemption. The interactive page (app/page.tsx) uses simple animations and icons to explain the flow between Alice, Bob (the mint operator), and Carol.

What this demo shows

• Phase 1 — Minting: Alice creates a secret, blinds it, Bob signs the blinded secret and Alice unblinds to obtain a token.
• Phase 2 — Transfer: Alice transfers the token privately to Carol (off-chain).
• Phase 3 — Redemption: Carol redeems the token with Bob, Bob checks the spent database and pays Carol, without linking the token back to Alice.

Why: This app is meant as a visual, educational explainer for Cashu-style blind-signature digital cash.
