An exciting sub-project within Monero is the possibility of using I2P[0] as a transport layer[1].
I2P is an onion-routing network overlay similar to Tor, but different in that:
- It focuses on internal services, rather than proxying out to the regular internet (though outproxies are available).
- Tor is designed primarily for TCP-based use-cases (proxying to the web). I2P natively carries both TCP and UDP.
- In I2P, every node is a router, unlike Tor where most nodes are just clients. Last time I checked, Tor had in the neighborhood of 6k routing nodes, and I2P had around 20k.
I2P is a fascinating project with a hard-working team that has been maintaining and growing the network for a decade. It's worth checking out.
