Hey Peter Todd, wondering what you think about ShadowCash? It seems pretty cool to me, but I am not nearly technical enough to completely understand the inner workings. I only barely grasp the concepts they are using, but it sounds pretty revolutionary.

They just released their shadow send feature and white paper a couple weeks ago. White paper here: http://shadow.cash/downloads/shadowcash-anon.pdf

Like stealth, I don't have the background to really understand the ring-signatures ShadowCash uses; I was contacted by ShadowCash to do an audit and deferred it to a cryptographer I know. They said the math looked to be a clone of Monero, done on top of Bitcoin. They were however potentially interested in doing an audit of the ring signatures idea to get a better idea of what kind of privacy it really gives people in practice - we'll see if they have the time to work on that further in the near future.

Best not to say more publicly than that given I just haven't done the research to really know.

The phrase "clone of Monero" would incense Ryno

Im sure SDC is not that (cryptonote) waiting on your friend

You guys are so stubborn.

Everyone who looks at it who understands this stuff at all (and I do somewhat, but I wouldn't put myself in the same category as a cryptographer referred by Peter Todd) says that is a clone of the cryptonote stealth address plus ring signature scheme, and then the same echo chamber here says "No, its not cryptonote!" As if that would even be a bad thing Huh

It's quite interesting to see.

Its because this is what the core developer is telling us.

Why there is no reference to Cryptonote on whitepaper?
Zero Knowledge + ring signatures is nothing more than Cryptonote.
Shadowcash is just cloning Monero without giving its credits and lying that is creating something new and revolutionary.
And everyone here know it.

From cryptonote white paper:

https://cryptonote.org/whitepaper.pdf

You can't read the reference at the end of the WP ?

Cryptonote uses a different curve, different libraries, and a whole different underlying core.
We used ring signatures to spend Shadow, which is created by sending SDC as an anonymous output.
Our scheme is quite a bit different, in that we borrow concepts from zerocoin, with the minting and spending, and use ring signatures to make the inputs untraceable from the outputs.. We're also using PoS instead of PoW.
Its a completely unique scheme and implementation
