"...Qortal..."
Qortal is developing Reticulum, a radio based (cell phones are radios) mesh network. That is the best idea I've seen to date. There may be other mechanisms that are being developed covertly. I sure AF hope so! There are extant mesh networks it seems to me H4x0rz could develop hostile parasitism on, such as LoRa, Bluetooth local, and etc. I reckon adopting all of these, because diversity is truly decentralizations strength, just as unity and conformity is centralization's strength.
There may be ways to ride on the internet parasitically. Again, I sure AF hope so. I do not know of any, though.
Reticulum is the one i was thinking of. i knew Qortal had plans for an alternative internet but didn't know they were planning to use Reticulum. i'm pleased to hear that.
