A minimal ActivityPub server.

Based on the specification: https://www.w3.org/TR/activitypub

Also: https://raw.githubusercontent.com/w3c/activitypub/gh-pages/activitypub-tutorial.txt

Goals

• A minimal ActivityPub server, comparable to an email MTA.
• Server-to-server and client-to-server protocols supported.
• Opt-in federation. Federate with a well-defined list of instances.
• Resistant to flooding, hellthreads, etc.
• Support content warnings, reporting and blocking.
• http signatures and basic auth.
• Compatible with http (onion addresses), https and dat.
• Minimal dependencies.
• Data minimization principle. Configurable post expiry time.
• Commandline interface. If there's a GUI it should be a separate project.
• Designed for intermittent connectivity. Assume network disruptions.
• Suitable for single board computers.
