I think we're trying to say exactly the same thing two different ways, as
you appear to have restated in the second paragraph what I was trying (in
my admittedly obtuse way) to say in the first one. What I was ultimately
trying to say is that a sneaky third party could "steal" a large number of
blocks from the Bovine effort, ON THE ASSUMPTION that one of the stolen
blocks is THE BLOCK. This third monkey--er, third party, I mean-could then
check the stolen blocks themselves, with no intention of reporting the
results back to Bovine. If they DO find THE BLOCK, then they go straight
to RSA and claim the $10,000.
Which brings to mind the terrible question: Do We Have Any Way Of Knowing
For Sure That We Have Not Had Blocks Stolen Previously?
If I were going to hack Bovine like this, I would write a few dozen of my
own bogus clients, each reporting under a different email addy, and set
them to request/report just enough blocks to put them in the top 1000 teams
area, but below the top 100. That way I wouldn't draw too much attention to
myself, but would be able to request a respectable percentage of the
keyspace over time.
Perhaps I'm being paranoid, but maybe someone should check to see if there
are an unusual amount of blocks being reported under different email
addresses, but all coming from the same IP addy, or even the same subnet.
What does everyone else think?
