Yep. See my continuation of this IP address issue here with some research I’ve done.
Let’s try to move Tor / IP issues there, and keep this to quantum matters mostly. Or, just let it flow because in the end, the quantum computer will be the end of us all. This is the end thread, my friend.
No perfect anonymity/security/privacy exists - but no perfect attacker exists either. Powerful entitiescan be unimpressive at times, and surprisingly make many mistakes, and also they have their own weak points and design weaknesses. One should assume nothing for 100% sure, which includes assumptions about threat actor’s abilities too.
I think Zcash, if the best technically possible OPSEC is applied to it, as I am working out*, approaches NSA-proof levels of money anonymisation (at least in the present day - who knows about post quantum), due to the default crypto design. To even discover this is astounding. No other coin AFAIK is at this level (and/r combination of enough network effect). This one is it. Innovate or die!
This ‘NSA-proof’ level of using Zcash is not (currently) convenient -
zcash-cli could do with much more hand-holding like
monero-wallet-cli - but it works! I agree with Zooko though that no level of privacy should be made hard or non-default for any user. It should ‘just work’. Outside of that, those who really want it can do these things discussed.
It’s not dangerous for Zcash to talk about this idea - what else seems NSA proof, ‘if done right’? Physical cash, AES-256, other pure crypto, other crypto designs and implementations (e.g. I think Signal messenger, i.e. the pure content encryption, not metadata). And no one’s banning those. I know money is especially touchy regarding the powers that be - money is directly tied to power and resources, which is what runs the world - but competing governments and corporations need to hide their information from each other too! The world needs perfect privacy, because everyone does.
I now think Zcash can have a beneficial symbiosis with Monero in terms of treatment by the powers that be, so that neither is ‘banned’ into oblivion. I’d bet that most Monero transactions are practically traceable by the NSA - much more than Tor - so it’s beneficial for them to keep it around and let people think they’re much safer than they are.
Whereas Zcash is the one actually securely private - and surely seen as beneficial to governments as an option when necessary, like Tor is. (I assume it needs to be a publicly traded commodity like Tor being a publicly used resource, to blend in with other parties, for public deniability.)
The people coming to Zcash are the few who ‘see the light’, by actually studying it. Maybe status quo of Zcash not being as commonly used as we’d prefer isn’t too bad, but some bolts need tightening and adding for sure. But if it shoots to the moon in usage or value for some reason, then woohoo, of course!
That’s the conclusion I’ve come to as well. It’s only about being anonymous ‘enough’, and trying your best. Pragmatism. Realism.
[*] and aside from being targetted specifically by nation state actors for existing, other reasons than just using shielded Zcash
