Every coin says this. Nothing against xc but do coins not check if others have currently working anon?
Fair point. Maybe I haven't checked sufficiently. Who else has it?
Let me know and I might be able to qualify what I mean by "working" and "anonymity". ;-)
All of the CryptoNote coins do (Monero, Boolberry, Bytecoin (BCN) etc.) They have working anonymity from their launch. If you take Bytecoin's claim at face value (it's pretty clear it's bullshit) they have been around for 2 years. Even knowing that it's likely a false claim meant to cover up their 82% premine, you still come face-to-face with an indisputable fact: Bytecoin's
first commit to github was on 15 November 2013, and already then the code worked and provided cryptographically untraceable and unlinkable transactions. Monero, too, was launched (fairly) on 18 April 2014, before XC even came into existence.
As much as I think Bytecoin is a fail because of their premine, they are the ONLY ones that can lay claim to having the FIRST "working anonymity". Monero and the all the other CryptoNote coins can lay claim to being the ONLY cryptocurrencies that currently have a 100% working solution to cryptographically untraceable and unlinkable transactions.
If you don't believe me, pick any transaction on the Monero blockchain (eg.

I'll gladly even setup two wallets and transfer between them and give you the transaction ID to give it a try. Oh and these transactions are instantaneous, no waiting for a mixing hop to finish or anything.
You're right about Cryptonote coins. I should've worded my statement more carefully.
My opinion of Cryptonote is that it causes an unworkable degree of blockchain bloat - so much so that it's unlikely to scale even on PCs, never mind on mobile phones. Boolberry have made hotly disputed claims about being able to reduce bloat, but to my knowledge this has not been implemented yet.
If a coin bloats, then in my opinion it should not be considered "workable", since it simply can't scale to mainstream (or even sizeable niche) adoption.
So although there's a clear sense in which Cryptonote coins are "working", there's also a clear sense in which they're not workable solutions.
XC, on the other hand, is designed from the ground up for mobile. It's eminently scalable.
