Are there currently any viable examples of this out there? “Viable” in this case meaning you can find stuff on there and it’s easy to set up, I guess
Only torrents work I2P at the moment. qtorrent and biglybt allow downloading torrents from I2P and the clearnet. There was an emule clone for I2P, but not sure if that still exists 🤔 There are anonymous websites (eepsites) just like onionsites - there’s an I2P torrent tracker called postman. No idea if somebody has figured out how to make IPFS or other tech work on I2P.
