"The Zerocash protocol extends Bitcoin and enables users to pay one another directly, via payment transactions that reveal neither the origin, destination, or amount of the payment."
I can't see many governments being happy with a service like this.
- sirdogealot 12y agoMy thoughts exactly. Matthew Green has carefully worded his presentation of this project in the past. He has always claimed that such an implementation could be possible. Not that it was inherent to the coin itself. Let's hope that he gets it running sooner, rather than later. Before somebody has a chance to change his mind.

It can, for example, let a user prove that he paid his due taxes on all transactions without revealing those transactions, their amounts, or even the amount of taxes paid. As long as the policy can be speci ed by ecient nondeterministic computation using NP statements, it can (in principle) be enforced using zk-SNARK s, and added to Zerocash."
