Here is an interesting article about Zcash Vs Monero
https://medium.com/@dcorbacho/zcash-vs-monero-zec-in-bitmex-fe1cd4f5f81c#.je0m531m6
And some information on how BITMEX is going to offer Zcash as a future contract instrument.
I will appreciate feedback if you spot any information that is incorrect, so I can amend it.
Interesting that Bitmex has Zcash futures trading.
.. that of Zcash (where your transaction is hidden amongst all outstanding transactions)
Not just all outstanding (JoinSplit) transactions: in Zcash, your notes are hidden amongst all other notes that have ever been created. Combined with the fact that coinbase must be entirely spent to a z-address using a JoinSplit, this means that the set of possible JoinSplit outputs that your JoinSplit could be using as an input increases continuously.
Note that this assumes no other information leakage. See e.g. https://github.com/zcash/zcash/issues/778 and https://github.com/zcash/zcash/issues/1360 for work being done to eliminate potential sources of incidental information leakage.
Why did You post this article? To promote Monero? I know a coin which already has advantage of both XMR and ZEC, but no need to post it here.
