<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 Bitcoin value without revealing the amount or the sender/receiver in public transactions. It leverages the Lightning Network for instant settlement while maintaining on‑chain traceability for regulatory compliance. Think of it as a privacy‑preserving UTXO that can be moved anywhere on the Lightning network.</p>

||

|
||
|
||
<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>
|
||

|

|
||
<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, but minting and redeeming are done via on‑chain transactions that are fully verifiable.</p>
