The attack you're thinking of was on Zerocoin, not ZCash; Zerocoin wasn't built by the team that came up with the zero-knowledge proof ideas, and was built on top of the original Bitcoin client code IIRC.

- runeks 9y agoI stand corrected. However, in the thread you link you it's pointed out that ZCash has no auditing built in, so it's not possible to actually see how many coins are in circulation. So saying ZCash hasn't suffered from a bug of this nature would be presumptuous, although it may be perfectly correct.
