There is an error in the paper:

Section 3.1:

"Note that be- cause darknet nodes do not communicate with opennet nodes,
there may be many disconnected darknets instead of one large network."

Darknet nodes can communicate with an opennet node provided there is an
out-of-band agreement between them, the hope being that this will prevent
the problem they describe.

Sorry if this has already been discussed - I was off the list at the<br>
time the paper was published.<br>
<br>
Researchers at the University of Minnesota carried out an address<br>
harvesting attack on Freenet opennet. They estimate the size of the<br>
opennet at around 2,500 nodes at any time, from a long-term population<br>
of around 11,100. It took a single node 2.5 hours to collect the<br>
addresses of nearly all active opennet nodes.<br>
<br>
Obviously the concept behind this attack isn&#39;t news to anyone here, and<br>
I realise it&#39;s not something opennet tries to protect against, but I was<br>
interested to see some empirical figures.<br>
