Lmao, even the shitcoin Darkcoin cant be compared to the even shittier shitcoin Shadowcash

Shadowcash's implementation of "ring sigs" is mediocre at best. In simple terms, it's kind of like a rusty, broken down version of cryptonote's ring signatures.

And u are? Pls provide some evidence for your claims and a member of the Shadow team will forward to Zeuner for review.

I can't speak for the person you're replying to, but I see this card being played a lot recently, and it gives me pause. Who is Isidor Zeuner, and what qualifies him to evaluate the cryptographic soundness of the proposed scheme as well as the merits and security of the code? I Google'd around to try figure it out, but to no avail.

According to his LinkedIn profile he is an "IT Consultant" whose "mission is to provide quality software solutions to demanding small and medium sized businesses."

His work history details that he has been involved in projects such as "custom functionality for embedded linux devices", "crawling, indexing and retrieval of content", and "web development".

I can find no mention of him on any publication available on arXiv, so given this body of evidence it's safe to say that he is not a recognised cryptographer (or a cryptographer at all).

I'm also not sure if the ShadowCoin team are paying him, but the top review on hie Freelancer profile is quite disturbing.

Don't get me wrong, in today's day and age nearly everyone has had something "controversial" splashed across the Internet, and invariably there are multiple sides to the story etc. etc., but nevertheless I think the term "renowned cryptographer" or whatever should not be bandied about without clarification thereof.

I saw that negative review when looking into Isidor also. It made me think twice for a bit too, but I don't think its fair to judge on one person's comments.

When looking further into him, I read his posts on the bitcoin developer mailing list. I saw he was active there and many times commenting on anonymity. This made me feel much better about him doing the review. Here is the link, you can search his posts on the bitcoin dev mailing list if you like: https://www.mail-archive.com/bitcoin-development@lists.sourceforge.net/

Here are a couple examples of his posts having to do with anonymity and Tor:
