cashu-feni

Cashu is a Chaumian Ecash wallet and mint with Bitcoin Lightning support.

Disclaimer: The author is NOT a cryptographer and this work has not been reviewed. This means that there is very likely a fatal flaw somewhere. Cashu is still experimental and not production-ready.

Cashu is an Ecash implementation based on David Wagner's variant of Chaumian blinding. Token logic based on minicash (description) which implements a Blind Diffie-Hellman Key Exchange scheme written down by Ruben Somsen here. The database mechanics and the Lightning backend uses parts from LNbits.

Please read the Cashu documentation for more detailed information.

This project aims to replicate the python mint implementation of cashu.
