> My question is whether freenet is designed to be resistant for active adversaries with deep packet inspection capability, particularly like the Chinese firewall that is also observed to do statistical timing analysis of packets? Is there any possibility to apply obfuscation to the peer to peer connection?

Freenet's transport protocol is a custom encrypted protocol over UDP, but it is not currently designed to evade sophisticated deep packet inspection or timing analysis by state-level adversaries like the Great Firewall.

That said, the transport layer is modular, and we would absolutely accept contributions adding traffic obfuscation or pluggable transports, subject to the usual tradeoffs around latency, bandwidth overhead, and resource usage.

Freenet uses a distributed small-world routing topology for peer discovery and efficient message propagation. It isn't a conventional Kademlia-style DHT, but conceptually it serves a similar purpose.

The network is designed to self-organize into a small-world topology.[1]
