What is a protocol?

A protocol is a standardized communication language that enables different software applications to interact seamlessly. Popular internet protocols include SMTP for email and HTTP for web browsing. When we refer to Nostr as a “protocol,” we mean that you’re not locked into using a specific app. Instead, there are many applications that speak the same language and can be used interchangeably — each offering its unique approach to functionality and user experience. This empowers companies by potentially eliminating vendor lock-in and providing the freedom to choose or switch between different implementations while maintaining seamless interoperability. By adopting this open protocol approach, we’re bringing value back to the buyers and sellers of materials through increased competition and innovation in the tooling ecosystem.
