I read the MAD-HTLC paper and I think it actually doesn't get into the size
of the collateral (v^{col}). I might have missed it though. Can you please
point me to the section in the paper where the amount is discussed?

I assumed that v^{col} has to be at least the size of v^{dep}. Otherwise,
Bob can threaten Alice with an HTLC bribery attack, and Alice knows that
Bob has very little to lose. Bob *should* have the same amount to lose, to
make it work - no?
