About

fmsg is a message definition and protocol intended as an alternative to email and IM apps. Like email it&#x27;s distributed – anyone can host a server for their domain. Unlike email, messages are binary, verifiable by all peers, and linked into a DAG using cryptographic hashes. Sender verification and message integrity are built into the protocol, so you get what email needs SPF&#x2F;DKIM&#x2F;DMARC for out of the box.<p>The host implementation (fmsgd) is written in Go. There&#x27;s a Docker compose setup to get a full stack running in minutes: <a href="https:&#x2F;&#x2F;github.com&#x2F;markmnl&#x2F;fmsg-docker" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;markmnl&#x2F;fmsg-docker</a><p>The spec is nearing v1.0: <a href="https:&#x2F;&#x2F;github.com&#x2F;markmnl&#x2F;fmsg" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;markmnl&#x2F;fmsg</a> — would love feedback.

AI Score Reasoning

fmsg presents a technically interesting DAG-based protocol to solve email's legacy security issues, but it lacks the necessary network effects and team pedigree to suggest venture-scale viability. The project currently shows minimal traction and faces extreme competition from both established incumbents and emerging decentralized standards like Nostr or Matrix.
