DIDComm
A secure messaging protocol for decentralized identity systems that enables private communication between people, institutions, and IoT devices.
What is DIDComm?
DIDComm Messaging is a secure communication protocol built on decentralized identifiers (DIDs) that enables private, machine-readable messaging between people, institutions, and IoT devices. It solves the problem of establishing trusted communication channels in decentralized systems without relying on centralized authorities. The protocol works across any transport layer, making it versatile for various applications.
Developers building decentralized identity systems, secure messaging applications, IoT communication platforms, and anyone implementing interoperable identity solutions that require private, authenticated communication.
Developers choose DIDComm Messaging because it provides a standardized, privacy-first approach to secure communication that leverages decentralized identity infrastructure. Unlike traditional messaging protocols, it's transport-agnostic and built specifically for the decentralized web, with multiple open-source implementations available across different programming languages.
Overview
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.
