"""The transport layer is responsible for both sending transactions to remote
home servers and receiving a variety of requests from other home servers.
By default this is done over HTTPS (and all home servers are required to
support HTTPS), however individual pairings of servers may decide to
communicate over a different (albeit still reliable) protocol.
