Monero vs. Zcash

I just read this article;

https://www.coindesk.com/edward-snowden-zcash-is-most-interesting-bitcoin-alternative/

Everything I know about Snowden leads me to believe that he's a stand up guy when it comes to infosec. In that read, he clearly endorses Zcash over XMR. And while I don't own or deal with either of those currencies (I am interested though) I'm curious as to what other people think about them.

Right now I see ease of use issues, and I need to do some personal reading on wallet options for both. Cash out is a whole different ordeal, not really part of the conversation I think.

As far as privacy goes, what do you Think? Discuss...

A detailed comparison of Monero and Zcash

In my view, ZCash's fatal flaws are trusted setup, transactions not private by default (here you can see that over 90% of zcash transactions are unshielded/public), 20% ongoing founders tax, and extremely high inflation.

Zooko the founder once tweeted something along the line that they can still track people using Zcash for criminal activity - meaning they own your privacy. Monero is the only coin that should be called a privacy focused coin.

"3,691.98 Zcash And an unknown amount of Monero. "

that should give you the answer

Snowdon is right the TECH is interesting which is why it's slowly being integrated into ETH But, and it's a really big but, Zcash is run by a company which can easily be forced by LE to provide information on users. The same isn't true for Monero.

Zcash was created by rich guys to make themselves richer. Fuck zcash.

Zcash is bullshit and it's equihash algorithm will be used in the upcoming "btc gold" fork.

Inputs from traced transactions into private transactions can be linked to one another, it also makes your transaction stand out if you're one of the only people not disclosing what you're doing. This also means the coin is not fungible; when you buy Zcash, that coin could have been used in an illegal purchase using private transactions, this means the coin you bought is at risk of being frozen or confiscated making it worth less than a Zcash coin that hasn't been traded illegally in the past. Well, if only 5% of transactions are private there's not a whole lot of places the money could've come from. So how would one go about tracing one of these 5% private transactions? Alice, Bob, and Charlie each have ten coins. You close your eyes so you can't see the transaction. You open your eyes and you now see Alice has 12 coins, Bob still has 10 coins, and Charlie has 8 coins. The transaction was completely private though... You or me not be able to figure it out on a larger scale, but a state actor or major corporation could. How does this scenario apply solely to zCash and not Monero? Wallet balances/transactions are never public with Monero, while they mostly are with Zcash. Alice, Bob, and Charlie each have ten coins. You close your eyes so you can't see the transaction. You open your eyes and you now see Alice has 12 coins, Bob still has 10 coins, and Charlie has 8 coins Because in Monero you can never see Alice, Bob, and Charlie each have ten coins in their wallet to begin with. UNLESS Alice, Bob and charlie EACH give you both the "view key" and their wallet's "address". Goodluck buttercup, because how do you know they start with 10 and endup with 12, 10, 8... unless they told you to begin with :)

the first part is how it obsurces. remember you keep seeing alice and bob putting in coins... or at least balance etc... monero you cant... also using "2 z transactions" would look VERY akward vs 2 normal monero spends. Also • τ is NOT quantum secure: gτ mod p is published. where t= trapdoor Whoever sets-up the Z.Cash system (CRS-based) might keep hold of some trapdoor information. • This trapdoor τ is material and real: the only hope is that it was erased! monero has hired and looked into quantum proofing. If your math is pretty good here is a college assignment at the University College London explain the difference of how both xmr/zcash/zerocoin works and their flaws. remember Z transaction look more suspect because it's only 5% of the network heres the University College London http://www.nicolascourtois.com/bitcoin/paycoin_privacy_monero_6.pdf also remember there is a difference Untraceable doesnt equal unlinkable :) Privacy / anonymity: in monero – for senders [Ring Signatures] – for receivers [Stealth Address] => “un-linkable” transactions => “un-trace-able origin” digital signature ***Various Forms of Un-Linkability • hard to link different PKs/addresses of the same user • hard to link different TXs of the same user • hard to link send different users (e.g. sender to recipient) remember IF i see ALICE BOB and CHARLIE PUTTING IN COINS something is up. Privacy / anonymity: for senders is gone... and it's only for the reciever of said coin... see the issue here

Monero > zcash! Zcash is back by J.P. Morgan bank. That's a bad sign
