A method for achieving forward secrecy in asynchronous messaging environments:https://whispersystems.org/blog/asynchronous-security/ …
@justinsteven You only lose pfs for the first message transmitted. Keys ratchet forward for subsequent messages.

@whispersystems unless the client stays offline and you're gunning messages at them, right? -
@justinsteven That's correct, no pfs until you get a response. Although the last resort key is rotated periodically as well. -
@whispersystems@justinsteven Why usage based rotation instead of time-based rotation? e.g. upload 1000 keys and rotate once per hour.
