NNCPNET Email Network

The NNCPNET email network is a peer-to-peer, encrypted Email[1] network based on NNCP[2]. It routes across the quux.org NNCP public relay[3] by default. It is a full-featured email system that doesn't require Internet connectivity, though by default it routes across the Internet. It doesn't require a public IP, DNS tricks, or port forwarding.

Email is one of the most common examples of Asynchronous Communication[5] people are familiar with today. It is a store-and-forward approach which is tolerant of temporary disruptions to services and supports multiple hops.

According to the NNCP documentation[7], NNCP[8] is intended to help build up small size ad-hoc friend-to-friend (F2F) statically routed darknet delay-tolerant[9] networks for fire-and-forget secure reliable files, file requests, Internet Email[10] and commands transmission. All packets are integrity checked, end-to-end Encrypted[11], explicitly authenticated by known participants public keys. Onion encryption is applied to relayed packets. Each node acts both as a client and server, can use push and poll behaviour model. Also there is multicasting area support.

NNCP lets you securely send files, or request remote execution, between systems. It uses asynchronous communication[13], so the source and destination need never be online simultaneously. NNCP can route requests via intermediate devices -- other NNCP nodes, USB sticks, tapes, radios, phones, cloud services, whatever -- leading to a network that is highly resilient and flexible. NNCP makes it much easier to communicate with devices that lack Internet connectivity, or have poor Internet.
