You should have posted some links explaining what zeronet is since I don't think people know what you're talking about. Here's a really soykafty description for anybody interested.
Basically it's another net, but not inherently anonymous. Websites aren't on a server, but seeded by peers. You can route it through tor if you want more anonymity, and i2p integration is coming soon hopefully.
Since it's for dynamic content, it requires javascript in your browser. It's also written in python.
Many sites can be used offline since once you download it there's a copy on your computer.
The file transfer is supposed to be similar to torrenting, similar to IPFS.
I don't know why it's on localhost, but I think that's the port where you request data from.
Also there are a lot of Chinese people there. I think due to the GFW (and because there are a lot of Chinese people)
