Zerocoin was initially conceived as computer code that would add anonymity to Bitcoin transactions. But it is now being developed as a separate currency after pushback from some Bitcoin advocates who are seeking to defuse the issue of criminality and win over Congress and federal authorities by arguing that Bitcoin transactions are traceable.
Matthew Green and his graduate students released a paper in April 2013 outlining how Zerocoin would work, hoping that someone would take the research to the next level and write the software code to support it. When no one did, they began writing the code for an exchange. They believe it will be ready in the spring or early summer. – Carrie Wells

Once Zerocoin is folded into the reference client all the IRS bluster will be moot. People will report what they want to and nothing else. – Beautyon
Used to find myself on pins & needles worried about regulatory agencies affecting bitcoin. Now I laugh at the notion. – Rey Poullard

Cryptonote Coins vs. Zerocash
Monero was forked from Bytecoin, and was not premined.
It uses Greg Mawell endorsed Cryptonote, which is the “ring signature” tech behind bytecoin.
“I wouldn’t be surprised if none of the current implementations of it are around in ten years though: Bitcoin emerged at a surprisingly mature state, the BCN/MRO/FTM stuff isn’t yet anywhere near as mature. But certantly darkcoin is totally uninteresting compared to this stuff. They’re also free of the trusted initialization challenges zerocash has” – Greg Maxwell
It’s a little disappointing to see how much ZeroCash is hyped compared to Bytecoin (https://bytecoin.org/), since the former is still vaporware while the latter is something real that you can go use right now.
If you’re looking to compare ZeroCash with competing technology, the comparison point should be Bytecoin. It’s also an altcoin (lame, because metcalf’s law applies— dividing up the cryptocurrency network effect is harmfful to all), but unlike ZeroCash it isn’t just a proposal— its an actual functioning system already – Greg Maxwell
Bytecoin is a ground up rewrite (for better or worse) blockchain cryptocurrency which uses a pretty boring schnorr-like ring signature in an _very_ clever way to achieve strong privacy. The ring signature its using has been peer reviewed, though the partial uncloaking technique they use to prevent double spending is a novel application.
The privacy achieved by Bytecoin is better than any existing-in-production privacy tools (e.g. CoinJoin) and also as good as or better than every theoretical system I’ve heard proposed except for Zerocash. Relative to ZeroCash, Bytecoin exists today and has simpler cryptographic assumptions, better performance for signers, and no requirement for trusted initialization. Because it doesn’t mask values its anonymity set is potentially smaller, though the implementation does some clever denomination tricks to reduce the harm of value transparency – Greg Maxwell
Unfortunately Bytecoin was premined. – Lee Banfield

Zerocash / Zerocoin (Not realeased yet)
It’s certantly better to see things like ZeroCash and Bytecoin being worked on… I’m really skeptical about the wisdom of splitting up the crypto-currency adoption network effect just to introduce some new transaction features. But certantly doing it with substantive new features is way better than just-another-worthless-clone – Greg Maxwell

I couldn’t give a shit about all this altcoin speculation stuff. I think it’s all rubbish, including the really unfortunate idea to release ZeroCash as an altcoin – Greg Maxwell

Coinjoin / Zerocash
“Bitcoin is traceable” is a misleading statement; we’re fixing that flaw.

Cypherpunks and The Crypto Wars 2.0
In late 1992, Eric Hughes, Timothy C May, and John Gilmore founded a small group that met monthly at Gilmore’s company Cygnus Solutions in the San Francisco Bay Area. The group was humorously termed “cypherpunks” as a derivation of “cipher” and “cyberpunk.”
The Cypherpunks mailing list was formed at about the same time, and just a few months later, Eric Hughes published “A Cypherpunk’s Manifesto“.
Cypherpunks believe that privacy is a fundamental human right, including privacy from governments. They understand that the weakening of a system’s security for any reason, including access by “trusted authorities”, makes the system insecure for everyone who uses it.
Some notable Cypherpunks and their achievements:
- Jacob Appelbaum: Tor developer
- Julian Assange: Founder of WikiLeaks
- Dr Adam Back: Inventor of Hashcash, co-founder of Blockstream
- Bram Cohen: Creator of BitTorrent
- Hal Finney: Main author of PGP 2.0, creator of Reusable Proof of Work
- Tim Hudson: Co-author of SSLeay, the precursor to OpenSSL
- Paul Kocher: Co-author of SSL 3.0
- Moxie Marlinspike: Founder of Open Whisper Systems (developer of Signal)
- Steven Schear: Creator of the concept of the “warrant canary”
- Bruce Schneier: Well-known security author
- Zooko Wilcox-O’Hearn: DigiCash developer, Founder of Zcash
- Philip Zimmermann: Creator of PGP 1.0
Cypherpunks write code. They know that someone has to write software to defend privacy, and thus they take up the task. They publish their code so that fellow Cypherpunks may learn from it, attack it and improve upon it.
Their code is free for anyone to use. Cypherpunks don’t care if you don’t approve of the software they write. They know that software can’t be destroyed and that widely dispersed systems can’t be shut down.
We have entered a phase that many are calling The Crypto Wars 2.0. Although the Cypherpunks emerged victorious from the first Crypto Wars, we cannot afford to rest upon our laurels. There are many battles left to be fought in the Crypto Wars; take up your keyboards and let us proceed together apace. – Jameson Lopp

The Dominant Anonymous Coin
Litecoin may be minimally useful as a backup blockchain, but it would make more sense for the number 2 digital currency in the world to be an anonymous coin.
A strong, dominant anonymous coin taking the number 2 spot with litecoin 3rd would seem like a sane world.
Privacy improvements in digital currencies are needed and although I’d prefer it to see it happen in bitcoin, I don’t mind seeing separate currencies working on it too.
Spending bitcoin through mixers is still the most popular way to pay for products on dark markets, but altcoins are accepted on some sites.
At the moment Dash is the most dominant anonymous coin by market cap, and Monero is the most technically advanced.
After years of hype, the anonymous coin Zcash (formerly Zerocoin and Zerocash) is scheduled to be launched on 26th September 2016 (although they have missed all of their previous milestone so further delays wouldn’t be surprising).
I probably should get around to finally buying some Monero. xmr.to is a pretty clever service.
We’re going to find out the hard way that Bitcoin will get outcompeted by currencies like Monero and Zerocash if we don’t act to get better anonymity and privacy into Bitcoin itself – Peter Todd
Monday 8th August 2016
I would like to see Bitcoin adopt greater privacy tools and be able to integrate good privacy systems but at the the rate of advancement of the Bitcoin protocol itself and gridlock, I’m not all that optimistic that Bitcoin is going to be able to do that. That’s one of the reasons why I agreed to invest in ZCash.
I think the more options and more tools people have the better. If it’s on Bitcoin, that’s great. If it’s on something else, that’s fine as well.
ZCash is coming out in September. – Roger Ver
