You can simply go to the official tor or i2p pages and read more about details, then do follow up research from there. With i2p there’s actually a few parallel implementations actively being developed. Original is in Java, there’s a C++ one, and then another one I can’t remember. Very new implementations are being made in Rust as well
I understand your sentiment. I wonder, if one were to “recruit” a lot of popular youtubers to stream in a decentralized fediverse manner by offering to make a simple hardware solution for them, would it encourage others to follow? How much of an investment would that be? Presumably you could keep the hardware “product” going and if more catch on they could also be directed towards your solution as helping them get in (quicker to market) as the network effect grows.
One would need to address the way people could monetize themselves aside from getting direct viewer support via subscriptions or donations.
