There really should be more private trackers on I2P. Once you get over the slower speeds, there are a lot of benefits, like not really needing to port forward to be connectable (but you should to support the I2P network).

You probably aren’t connectable from the outside. You need to port forward to support the network.

IPFS is kind of like the BitTorrent DHT. Every file is indexed by a cryptographic hash and can represent anything. There is no general way to search it, but you can build an index and search the index like how torrent search engines work.

You don’t need a VPN if you use I2P!
