<h1>Cashu – Chaumian Ecash on Bitcoin</h1>
|
||
<p>Cashu is a lightweight, privacy‑preserving ecash system that runs on top of the Lightning Network and settles
|
||
on‑chain. It uses zero‑knowledge proofs to hide the value of a transfer while remaining fully traceable when
|
||
required.</p>

<h2>What is Cashu?</h2>
|
||
<p>Cashu is an ecash protocol that allows you to mint, transfer, and spend sats without revealing
|
||
the amount or the sender/receiver in public transactions. It leverages the Lightning Network for instant
|
||
settlement on nodes. Think of it as a
|
||
privacy‑preserving bearer instrument that can be minted and redeemed across on the Lightning network.

|

|
||
<section id="privacy">
|
||
<h2>Privacy & Zero‑Knowledge</h2>
|
||
<p>At the core of Cashu is a zero‑knowledge range proof that proves the value of a note without exposing it.
|
||
This means you can pay for goods or services with a Cashu note and the recipient can verify that the
|
||
note contains sufficient value, while the transaction remains private on‑chain.</p>
|
||
</section>
|
||
|
||
<section id="technology">
|
||
<h2>Underlying Technology</h2>
|
||
<p>Cashu uses a set of “notes” minted by a mint and signed with a unique key. Each note contains an amount
|
||
and a unique identifier that the mint keeps encrypted. Transfers are executed with the Lightning
|
||
Network, and does require a mint to mint notes and therefore requires some level of trust in the mint.

|
||
<h2>Getting Started</h2>
|
||
<p>To begin using Cashu, you’ll need a Lightning‑ready wallet that supports the protocol. Most of the
|
||
wallets listed above have a <code>Cashu</code> switch or integration. Once installed, create a new Cashu
|
||
account, mint a few notes, and start experimenting.</p>
