SDMP 0.12

Secure Distributed Messaging Protocol

A software and network agnostic protocol for distributing messages across a cryptographically secure, peer-to-peer network.


At its heart the SDMP is just a protocol for machines to communicate messages to each other, in a secure way that humans can understand.

If humans can understand it, it's easier to make sure the secure part is actually secure.
