TPTB_need_war has repeatedly been stating that Zerocash does not need IP obfuscation and therefore is not subject to I2P/TOR, which are, in his opinion, flawed.
However, it seems like Zerocash actually needs IP obfuscation as well and they seem to go with TOR, see ->
(starting point).
Look way back in 2014 when you launched Monero, I told you smooth and fluffypony that IP address correlation was the weakness. Fluffypony proceed to try to integrate I2P. I warned you all many times that was not an adequate direction. But you wouldn't listen.
I2P, and even somewhat Tor, is perceived as adequate by 99% of the market. The remaining 1% may be smarter but isn't obviously much of a market at all. Very niche-y.
By the speculators because they are clueless.
But the corporations do not use darknets. They want privacy on the block chain, like we have disk encryption. Mention dark nets, illegal drug trade, etc, and they won't touch it with a 100 foot pole.
I would guess that many corporations do use Tor now for certain things. I2P will be integrated and invisible. No one will know or care how it works, except that the obvious network level vulnerabilities having to do with broadcasting transactions will be removed, and it will pass routine (though not intelligence agency level) technical muster for being private sufficient to satisfy most of the market. That's my opinion, and you are welcome to disagree.
Zerocash still needs IP obfuscation for a lot of private usages in practice too. They acknowledge it in the paper.
Zerocash does not need IP obfuscation when all the transactions are in the private zerocoins. Cite the section of the paper. I think you must be misunderstanding something. You are probably conflating the use of the regular non-anonymous coins mentioned in the paper.
Here you are making excuses again. Corporations are not going to trust unprovable shit. And moreover, mixnets are always vulnerable to flood attacks. They are very, very unreliable. Not only do I disagree, but I also think you are ignoring basic fundamental realities about the technologies.
Edit: arguing for Tor/I2P is akin to arguing for Dash's off chain mixing. Now look in the mirror and remember your arguments for End-to-End Principled ring sigs (versus off chain mixing) and realize the same logic applies to why Zerocash is superior to using off chain mixnets. Hypocrite.
Edit#2: okay I see the section you are referring to:
6.4 Additional anonymity considerations
Zerocash only anonymizes the transaction ledger. Network trac used to announce transactions,
retrieve blocks, and contact merchants still leaks identifying information (e.g., IP addresses). Thus
users need some anonymity network to safely use Zerocash. The most obvious way to do this is
via Tor [DMS04]. Given that Zerocash transactions are not low latency themselves, Mixnets (e.g.,
Mixminion [DDM03]) are also a viable way to add anonymity (and one that, unlike Tor, is not as
vulnerable to trac analysis). Using mixnets that provide email-like functionality has the added
bene t of providing an out-of-band noti cation mechanism that can replace
Receive
.
Additionally, although in theory all users have a single view of the block chain, a powerful
attacker could potentially fabricate an additional block
solely
for a targeted user. Spending any
coins with respect to the updated Merkle tree in this \poison-pill" block will uniquely identify the
targeted user. To mitigate such attacks, users should check with trusted peers their view of the
block chain and, for sensitive transactions, only spend coins relative to blocks further back in the
ledger (since creating the illusion for multiple blocks is far harder).
I will need to understand this attack better. Seems to me they are saying that you need to spend from a block where your pour transaction was the only transaction in the block. But the user would I think know this and thus not spend the coin any more. Thus I believe the anonymity remains provable without the use of any mixnet. I will need to understand this more deeply to be sure.
Bear in mind that I2P will be integrated in Monero, but you can always choose to run Monero over TOR if you want.
