At the cost of *greatly* strengthening aggregation.
Suppose there is currently many makers, all with roughly-equal bonds.
Suppose I were to approach two of these makers, and offer to aggregate their
bonds.
The combined bond would, because of the V^2 term, have 4 times the weight of
the other makers.
Thus, approximately I can earn a little below 4 times what one other maker does.
I offer 1.5x what one maker does to both of those makers and keep a little
below 0.5x to myself.
So:
1. I earn without putting any of my money into bonds.
I just need starting capital to pre-pay for the rents.
2. I get to learn a little below 4x more CoinJoins than other makers.
This increases my earnings further since I can sell this privacy
information, and I also get an advantage compared to other non-aggregating
spies.
It seems to me not to fix the root issue, i.e. makers who make for the purpose
of gathering privacy information, even if it might fix sybil attackers.
