"""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.
