ZeroCash: 2nd gen with anonymization starting from the coinbase transaction

[tacotime]

Not a lot is known about this, as M. Green has been keeping very quiet.  The most I know is from these slides.

The transcript from the presentation is here: http://pastebin.com/raw.php?i=q3rgh5ZY

Fun facts:
- ZRC uses Succinct Non-interactive ARguments of Knowledge (SNARKs) for proofs, which are only 288 bytes in size for 128-bits of security
- Tradeoff is the time it takes to generate proofs for splits/merges (measured in minutes)
- Verification of proofs in milliseconds
- Release date: May 2014

I checked their website and this was posted 'We will be updating this site soon to include details of our new version described by Matt Green at Real World Crypto 2014".

looking forward to this coin!

Looks interesting.

i'd really like to know more since i am preparing a talk on this general topic. the video is now set to "private" on youtube.

It's because the publication of the paper is forthcoming and the source code is proprietary.

Judging by the success of darkcoin we will see more anonymity features in new coins.

I like coins that focus on anonymity for sure, I think it will be something like this that could possibly overtake Bitcoin because Bitcoin definitely isn't anonymous.

DarkCoin's CoinJoin is more a privacy feature, not true anonymity as provided by the use of ZKPs.

Just wait for Darksend

I'm also one of those who can't wait for zerocash.

I expect massive adoption by sites like silk road 2.0 and such. I expect several states declaring it illegal. And of course I expect its value to heavily rise in the middle of war with governments and other negative-hype-raising events.

It'll be grand, my friends.

In the video Dr. Green urged everyone to be cautious about the adoption of the currency -- there's one pitfall if I understand correctly, and that is that since everything is obscured (even the generation of new coins via block subsidy), you can't observe actual inflation in the currency (just try to predict it based on the programming of the source code).  That is, if there were a bug and someone were to generate 2 billion coins (as what happened with Bitcoin), there's no real way to observe that.
