There are now many technologies for P2P file sharing:
- Usenet
- Bittorrent
- IPFS
- Tenfinger
- more?
And also several technologies for anonymization:
- VPNs
- Tor
- I2P
AFAICT the most popular option is still Bittorrent with various public and private trackers and indexers. Private trackers seem to be the most effective option that communities have converged on.
I’ve tried all of the above solutions over the years and while I think something like I2P sounds great in theory, it doesn’t seem to actually work well in practice. Because it’s not terribly popular, it’s hard to know what to expect.
We clearly still haven’t found the ideal model that can provide both good performance, discovery, access, availability, and anonymity. But do you think we will actually make progress on these problems? We seem to have stabilized on a local maximum.


BitTorrent is a good middle ground between decentralization, adoption and user-friendliness. I think the transport layer is pretty solid, and there’s no need to stick an anonymity layer at the protocol level, as the preferred method might change over time.
Combined with a VPN to handle the anonymity part, I think it’s solid and modular enough.
I agree the transport layer is good and having anonymity in a different layer works. I think my main gripes with it today are:
