What is your favorite Darknet or Deep Web Network? I've been a user of I2P for a good 7 years now, before I even heard of Tor, which I've been using for about 5 years as well.
And then there is ZeroNet, which although the focus is not anonymity, does a great job in ensuring distribution and longevity through seeding a-la torrent. This concept got expanded in IPFS, though I used it mostly with files instead of web pages.
I'm still curious about the likes of GNUNet (which I hear it's a complete stack with even its own DNS) or FreeNet on which I2P was based. Got any other I didn't cover?
