World Server - Action Server trust

[calummackervoy]

I'm a World Server.. How do I trust an Action Server's action ?

I could define a personal whitelist, but this might harm the interoperability of action and world servers

The conflict between security and interoperability could be softened if a federation/community structure manages a whitelist/blacklist. Possibly World Server's should keep track of operations and roll them back if needed, but this might be a difficult operation unless it's very fresh (e.g. imagine undoing a butterfly flapping its wings 20,000 years ago)

Ping @MattTennison you might find this one interesting. Storing federation spec-related issues in this repo because it's where I've started writing the early federation design specs (#1 )
