H was reading about atomic cross-chain trading in the wiki link above and think that perhaps the Zcash circuit could be used to easily get semi-private Zcash-Eth atomic cross-chain trading.
As in the wiki above it would require the parties to communicate before and verify by themselves that certain things have appeared on the two chains. On the other hand, it doesn't require Eth chain to verify Zcash Proof of Work as I thought was needed. What the Eth client will need to do is verify a snark of the Zcash circuit (which was recently implemented for the C++ client as described in https://z.cash/blog/zcash-eth.html)
Semi-private means Alice will agree with Bob to exchange say 10 zec for 1 eth, and this 10 will only be know by both of them. Furthermore the address to which Bob's 10 zec note will be sent will be a z-addr known only by him and Alice.
So here's how it could work (simplified)
0.Alice will send Bob the Eth address Addr where she wants to receive her 1 eth
Recall a Zcash note consists of a value v, pu
