A long time ago there was a talk on what happens when a completely closed Dark
network gets a single connection (or a couple of connections) to the outside
world. If i recall correctly you said that currently it breaks the routing quite
significantly (from the outside the whole network is seen as a single point). In
here the problem is even larger, it is possible to have a closed darknet, and
then every so often somebody can connect to the outside larger network. That
"brave node" may be different, thus the location of the "point" which is
connecting will change (when looking at this darknet from outside).
Has something changed to make the closed darknet be able to connect to the
larger network via a single connection?
