Yep, I'm gonna give a second request for what i2p is? Seems to be similar to tor? Can someone explain the differences? (Sorry for what might be a very elementary question)

See https://news.ycombinator.com/item?id=24254844

What’s i2p all about then? I took a look at the website and I’m none the wiser. Is it something like Tor?

Yes, it is like tor. See https://en.wikipedia.org/wiki/I2P, https://geti2p.net/en/about/intro, https://geti2p.net/en/faq, and https://geti2p.net/en/comparison/tor.

I’m still not getting it.

Is there a single i2p universe or do you have separate self hosted instances. What does i2p offer that Tor doesn’t? Are there active sites or communities it is it just a routing layer?
