I would then encourage you to look up how those work and what proof of work actually is. Proof of work requires some work to be done by the client. If you want regular people to browse the internet normally and “do work”, that means JavaScript, otherwise it requires them to install an extra binary like TOR or something, which would lock out most of real users. I imagine that’s not the goal of site operators.
I don’t know of a tutorial, but most tools have to have support for I2P built in, otherwise they won’t work. A good torrent client that does is qBittorrent.
Browsing I2Ps network with HTTP happens over a SOCKS5 proxy, so if aria supports that, you can use it too. https://geti2p.net/ should have more information.
