DIDComm

DIDComm Messaging is a communication methodology that enables secure, private interactions between entities using decentralized identifiers (DIDs) as the foundation for security and privacy. It provides a standardized way to exchange machine-readable messages across any transport layer, making it essential for building interoperable decentralized identity ecosystems. ## Key Features - **Transport Agnostic** — Works over HTTP, Bluetooth, SMTP, raw sockets, sneakernet, and other communication channels - **Decentralized Security** — Uses DIDs as the basis for authentication, encryption, and privacy - **Machine-Readable Messages** — Enables structured communication between people, institutions, and IoT devices - **Specification-Driven** — Developed through open standards processes with multiple independent implementations - **Privacy-First Design** — Built with strong privacy protections and security guarantees ## Philosophy DIDComm Messaging is designed to be an open, interoperable standard that leverages decentralized identity principles to create secure communication channels independent of centralized authorities or specific transport protocols.
