Calle and Collaborators Build Nostr Directory for Bitcoin Ecash Mints

Calle and collaborators are developing an Internet Mint Finder on Nostr to organize Bitcoin (BTC) ecash mint announcements and reviews, giving users a shared directory for evaluating services they must trust. Cashu is an open-source protocol for issuing Chaumian ecash on Bitcoin. A mint is a service that exchanges Bitcoin for ecash, and users rely on the operator as part of that arrangement. Choosing a mint therefore involves trust, a point explored in TokenPost’s earlier coverage of Cashu’s mint trust model . The directory uses NIP-87, a Nostr format for messages about mints and reviews.
