# Milk Market

> Milk Market is a permissionless, Bitcoin-native marketplace for local food and decentralized food systems, built on the Nostr protocol. Producers sell raw milk and dairy, meat, eggs, produce, baked goods, honey, and other local goods directly to buyers, with no platform gatekeeping. Payments work over Bitcoin (Lightning, Cashu ecash), cards (Stripe or Square), and manual fiat. AI agents can browse and buy, and sellers can manage their stalls, through a Model Context Protocol (MCP) server.
