It needs to be verifiable to be protected from spoofing, and encrypted to be protected from listening. You can't verify arbitrary network traffic because servers aren't stateless, but you can encrypt some traffic (https). Sadly, the encrypted traffic still has some metadata, such as server ip, sometimes hostname, request size. Either way, it can't be protected in the way filecoin/gridcoin are protected.
