What needs to be said here is that they apply a fundamentally bad notion 
of 'offline payments': delayed deanoymiziation of double-spenders is not 
only making privacy brittle, but moreover is insecure as deanonymization 
doesn't imply that you can recover the funds --- or even that the double
spender is truly guilty. So naturally they don't bother to explain these 
social implications of their design in the paper, but those are critical 
and the reason why this approach will fundamentally never fly.

my 2 cents
