Experiments in libp2p connectivity
Custom libp2p-based Go binaries for testing p2p
connectivity in the following scenarios:
- Public ipv4 to public ipv4
- Public to private (behind NAT) and viceversa
- Private to private (behind NAT, using holepunching)
- Using the Tor transport
Assumptions
I am exploring the possibility of creating network conditions which resemble those of the scuttleverse. Peers are offline friends and have some out-of-band method of connecting to each other first. So, for example, I don't want to make use of a public DHT by default.
To facilitate holepunching and avoid public IPFS relays or DHT, I want to use a private self-hosted relay. No standard bootstrapping nodes should be required, everything is "in house" (like a "pub" or "room" in SSB).
I make explicit use of Noise for encryption because I control the peer implementation on both sides (guaranteed to be available).
Sometimes, it might be handy to make use of public IPFS relays or DHT, so I will leave this as an optional approach. The important point is that this will not be the default.
Local-first connections should also work.
Since libp2p was built within the context of a global connectivity mindset, I
am exploring whether the feature set works for peer connectivity between a
small group of friends.
Goals
Simple and well documented example programs.
Show possiblities for using overlay networks from the start.
