Can somebody tell me why Shadow would need Ring Signature with ZeroKnowledge proof?
There'd be a bloat in the chain, no?
I'm confused, especially because they didn't talk about their "how to approach ZK" - I doubt the use Zerocash, I doubt they use Zerocoin, and maybe the coin later depends on decentralized servers relaying the transactions building the system on "fake" anonymity.
No coin ever really achieve true anonymity, I really doubt that Shadow, Monero, Anoncoin, Dark and all the others are able to do this.
I've been here since 2013 and I only - repeat - ONLY experienced that Coins/Coindevs fuck with people, no matter how holy they might seem, no matter what they have achieved/coded in the past. - Be careful here - Don't go 100% into a Coin, diversify.

I mostly hear positive voices when it comes to anonymous coins, its very strange to me, because mostly every "anonymous" coin is not anonymous, and the many coins that claimed to be anonymous fucked people over.
