How to Create Your Own Decentralized Messenger Protocol

Building a decentralized messenger protocol requires a federated architecture similar to email (SMTP), where independent servers communicate directly with each other using a standardized protocol after discovering each other through DNS lookups. Key requirements include end-to-end encryption so servers only handle encrypted data, domain verification to prevent spoofing, and user identities formatted as `@` to enable proper routing between federated servers. This approach eliminates the need for centralized orchestrators while maintaining security and interoperability.
