hey everyone! did you know cars are really just the same as a horse and carriage because they both have wheels, i know crazy huh! just like SDC and Cryptonote are the same because they both have ring signatures..

You mean like if rhinos and ponies are the same 'cause they're both mammals + have 4 legs? Smiley



LOL, just havin some fun  Grin

Shadow is as much based on CryptoNote as CryptoNote is based on Bitcoin by your analogy. Surely because CryptoNote has a blockchain and uses PoW the CrytoNote developers based their entire technology on Bitcoin? That sounds as absurd as your statement saying Shadow is based on CryptoNote.

You may claim that is absurd, and yet, the cryptonote whitepaper references bitcoin extensively! They recognize that their system takes many ideas from Bitcoin and builds upon them. They likewise give credit in their white paper, and clearly explain what part of their work is new and what is based on bitcoin. In fact the entire first section of the cryptonote white paper explains this. Have you read it?

Can you clearly explain this (i.e. which parts -- specifically -- are original, and which are derivative) with respect to shadowsend? Because the shadowsend whitepaper doesn't.

Quote
just because ShadowSend uses Stealth Addresses + Ring Sigs does not mean it functions like CryptoNote

That is nonsense, because stealth addresses plus ring signatures is exactly the method used by the anonymity functions of cryptonote, and cryptonote was the inventor of using these methods for a distributed cryptocurrency. Why is that so hard to understand?

Quote
Shadow keyimages are reusable whereas in CryptoNote they are one-time if I recall correctly.

False. Quoting from the Shadowsend whitepaper: "The blockchain is searched for the provided keyImage, if one is found the transaction is
considered a double­spend attempt and denied."

This works exactly the same.

Quote
The list is endless of how Shadow differs from CryptoNote.

The list is not endless.

As far as I can tell the list is:

1. Shadow transactions occur on a Bitcoin-style chain (transaction formats, etc.), wheres the cryptonote implementation has its own blockchain and transaction formats.

2. Shadow shares a blockchain with a non-anonymous coin SDC. Operations allow exchanging one for the other.

3. Some relatively minor implementation details of the Shadow anonymity scheme differ, such as the denominations used. Likewise, I read somewhere that Shadow uses a different elliptical curve for its elliptical curve cryptography, though I can't find that in the white paper.

Quote
This is my opinion and not that of the brains behind ShadowSend

Then why are you arguing about something you don't understand?

I read the thread, just want to watch it to get the answer to this post.

Bear in mind a crytographer is involved in Shadowsend, Techovert. If, as you say, ssv2 is an implementation of cryptonote, then why would Ryno collaborate with him? Ryno certainly has the skill to build an implementation of cryptonote without any help…

I'm not familar with this technovert. What else has he accomplished?

Assuming your developer is not a cryptographer and employed the assistance of one, that speaks well of him. There are certainly aspects of shadowsenc that are different from cryptonote (such as the way it integrates with the non-anonymous SDC), and any changes or differences in context should be reviewed by a cryptographer, yes.




Alice makes cupcakes, she puts them in the same brand of tray that bob does. Except bob has refined his process and has a far better cupcake mixture then Alice. So Bob gets a far better review for his cupcakes. Even though Alice was using that same cupcake tray a while before bob was. It clearly seems irrelevant that Bob or his reviewers acknowledge Alice because she used the same tray!

You are implying bob should give credit where credit is due. I think you are off your tree
 if you think this is anything like cryptonote besides using ring signatures! Which might i add are not cryptonotes invention, as you know!

Cryptonote uses a different curve, different libraries, and a whole different underlying core. For starters SS2 does not send the entire ring.
The scheme is quite a bit different, in that it borrows concepts from zerocoin, with the minting and spending, and use ring signatures to make the inputs untraceable from the outputs.. It's also using PoS instead of PoW. Its a completely unique scheme and implementation. End of story!

Now, to get onto the topic of technovert. He is rynomsters partner, they have been working on this project together from the beginning as far as i know.
You believe its the same as cryptonote, we don't, so lets just leave it please. I'm really getting sick of seeing dadon react.

FYI @dadon, people don't belong to certain threads. Smooth may be a bit passive and seems to have some sort of agenda here on first glance but he really does not "belong" in any thread. This is free for everyone who contributes. Smooth is at least contributing. If all we have is some weak comparison to cryptonote through a ring signature. Which is like saying ShadowCash uses "if" and "while" statements in its code like bitcoin "nothing special" "credit where credits due"...

I know you know this but i really don't like that "please return to your home". Just counter argue him/her, you have all the facts and history laid out before you to shoot back at some of the things he/she says.


This implementation is the foundation with which to slot in snarks. It will, again, blow anything close to it away! Again... Buy Shadow, don't buy it. Its of no consequence, it is the leading anon project. Very few people are willing to openly accept it yet.

Some quotes from Ryno to refresh your minds :

Our scheme was never going to be perfect, and we have said on a few occasions that we will only be utilising a basic nizkp until zk-snarks is fully out and trustless.

The reason we opted for anonymous tokens, instead of direct anonymous outputs to ringsigs, is because we're building towards direction we're heading in. What we're striving for... Encrypted values, with perfect nizkps, proving all values of inputs are real, without revealing any information about where they come from.

We're looking at many things, like homomorphic encryption, snarks, etc...
http://eprint.iacr.org/2014/976
snarks are advancing, along with many other ideas... We are not for limiting ourselves, but for bettering our [collective] future




This implementation is the foundation with which to slot in snarks. It will, again, blow anything close to it away! Again... Buy Shadow, don't buy it. Its of no consequence, it is the leading anon project. Very few people are just not yet ready to openly accept it yet.

Peter Todd's comments were interesting on that thread.  He is saying that getting faster zerocash SNARKS are more important than getting rid of a trusted setup because it will take several minutes to sign a transaction.  Its interesting that SDC may mitigate that problem because you only have to wait the extra time when using Shadow for anonymity.  When using the regular SDC it will be fast as normal.

What perplexes me is why people are bending over backward to claim that shadowsend doesn't use (something very close to the) the cryptonote design for anonymous coins. It's a great system, the best one around. Your project and developers should be congratulated for choosing it and apparently implementing it effectively.

Instead this turns into a food fight over claims of "No, it's completely new!" (which as someone else pointed out is rather silly even if it weren't incorrect with respect to cryptonote, since every single coin is copied from bitcoin) and who is supposedly advertising in your thread. Silly.

Just give cryptonote their due credit for their part of all this (which is sort of done in the white paper since they are listed as a reference) and get back to the business of building and promoting the coin.

The reason for the behavior could be that they were told Shadow would get "ZK" and that would blow everyone's minds and make Shadow stand out and make everything else obsolete. It's tough to give up that thought.

What you upset about? Everyone knows that site is a ponzi scheme, and apparently coins get dumped instantly to push the price down and hopefully pick up double the amount of coins if enough people panic sell.

i am telling it again....

in order to prevent such sites, price moves which harms shadow, we need a market maker to stabilize the price...sell upon excessive demand to prevent hype and buy to prevent price push downs

big holders of shadow should organise that fund...what i see, shadow is not owned by strong investors who can punish such sites/people when needed...

now, shadow is like back garden of some people where they play anygame they want...

without stabilized price; marketplace, using shadow as a fiat, etc will be just dream

I agree, these things are harmful to all crypto just by existing. Every time a crypto crook makes the news the legitimate businessmen are less interested in accepting what we offer. And the politicians are more interested in imposing regulation. The bastards in Washington are just itching to enact laws controlling us, these incidents just give them ammunition.

Try ShadowCash, the first coin with instant and decentralized private transactions!

Hey Everyone,

Just spoke to Ryno he's had a nasty flu last few days.. He'll be on soon as he's on his feet to respond to inquiries.

Thanks all!
