[tor-talk] Questions on the coming next-gen onion services

Will the next gen hidden services be more at risk of deanonymization during this transition period?

Good question. Onion services need basically three different type of relays,
HSDir (directory), Intro point (IP) and Rendezvous Point (RP).

The tor 0.3.0 release has the next-gen support for HSDir and IP. For the RP,
the all current relays will work with next-gen. And for IP, next-gen services
have a legacy option to use old IPs (<= 0.2.9). It has been put there for this
transition period where we expect to have unfortunately a lot more tor out
there that don't support next-gen.

What is left is the HSDir that will have to be selected based on the protocol
version advertised by the relay. So at first, there might be very few of those
so there will be a period of time before we reached what we call "network
maturity" which will allow us to switch from the current service protocol to
the next-gen for all newly created services.
