So this was done with other cryptocurrencies, they had a prize for anyone who could hack network/address of the coin. Zcash could do something like this. They could offer people Zcash for those who can reveal the hidden information Z-addresses provide. Showing the power of Z-addresses can show the rest of the industry that Zcash is as secure as we say it is. Just some thought. What do you guys think?
A bounty could be a good incentive.
I like your idea!
