Yes! It's a fairly new, but nonetheless impressive system called Reticulum. If you're familiar with mesh networks, it is essentially an entire networking stack you can flash to many devices, even an ESP-32. It has the ability to use existing infrastructure as well, so it can bridge the gap between mesh nodes and the greater internet on its own.

Personally, I have one ESP32 node for Meshtastic, and another for Reticulum. They run on the exact same hardware, like a prebuilt Meshtastic node you can buy online is one firmware flash away from (hypothetically) cutting out the ISP. As per usual for these systems, they're completely decentralized and under the control of the community. Truly a piece of software I would love for every modern router to ship with.

As far as TOR relevance goes, it doesnt use TOR itself, but the infrastructure behind it has anonymity built in through a similar node system. I dont understand the full scope of how deep it runs, but these links below should be able to shed light.
