Someone is mentioning ShadowCash in the comments.  I tried to comment to mention ShadowChat and ShadyBay but it would not let me.  Also Adam Back the inventor of Hash Cash is posting in the comments.  Sure would be good to get on that guys radar!


Edit: Looks like they just deleted the guys comment about ShadowCash!

I e-mailed Coindesk and pitched them ShadowCash for a story. Told them about Shadow Send being implemented. I sent them tons of links and information. Told them about Shadow Chat and ShadyBay decentralized marketplace soon.  Told them Ryno would probably do an interview, I am guessing since he did an interview before for some smaller crypto news sites.  I remember several months back during the DRK bubble, Coindesk had a story saying "How Darkcoin became the king of alts".

I think we have a better chance of getting on their radar if more of us send inquiries to them:  http://www.coindesk.com/contact-us/

Yes keeping a large pool of Shadow on hand seems ideal, then spend smaller amounts from the pool.  Just use common sense.

Maybe check out this slide presentation, I think it explains it well: https://docs.google.com/presentation/d/1yX2jN618Rnzs4g2ri_utdKdHbny6-xnRcPhOuhLNGB0/edit?pli=1#slide=id.g577a31a2a_086

Hopefully we will have some respected people review the code.  There are still some attack vectors if you don't take precautions with your amounts and timing.  For example, you transfer 27.75664321 SDC to Shadow.  Then 5 minutes later u turn the exact same amount less the fee back to SDC, its going to be pretty obvious.  As for the crypto, there are probably some attack vectors if the ring sizes are too small and such things.  I am not an expert, but Rynomster the lead dev should be coming back soon to help clarify our questions.  He has been sick with the flu lately.

Also as for off-chain/on-chain solutions that depends on what your exact definitions of those things are.  But taking it to mean one way, it could suggest that an off-chain solution is a centralized solution.  This causes problems with trust.  On-chain solutions have issues as well.  I think coin-join solutions kind of fall short, and have too many attack vectors from a government adversary.  Zero knowledge crypto is a much better solution in my opinon, and it should be done "on-chain" depending on your definition, and it should be done with zero trust as well. Some of the crypto has to be set up using a trust model, trusting on the people who set it up, but from what I understand Shadow is striving to eliminate that need for trust, and still have complete zero knowledge anonymity.

I am going to e-mail coindesk and ask them to cover the Shadow project and the recent implementation of the Shadow send feature. The anonymity along with Shadow Chat, and the soon to be decentralized marketplace would make for a good story.  Maybe its a longshot, but they do say they accept news pitches.  It might help if others contact them as well: http://www.coindesk.com/contact-us/

Ok, well it is the best anon solution on the market, you said it wasn't and I asked you to tell us what is better and why and you have failed to do so. So your contention with Ryno is he should have copy pasted the code like a "good dev".  From my understanding Ryno and the devs are working towards a future goal very methodically.  Your accusation that the code was "maybe only changed so it would not be a 'copy'" really lacks any evidence to back it up.  It does not seem very logical for Ryno to do that.

It sounds like you are mad that they are competing with your coin, and "trashed" your coin.  I don't think anyone is trying to make enemies here, but we did get a lot of attacks from other coin devs coming here and acting rude to us. Some of their criticism was constructive, but much of it was not or it was delivered in a snarky or misleading way.  Some from the SDC community lashed back as humans do.  I would like to reach out to you and welcome you into the community.  It seems we have a common goal of crypto privacy.  I think all of the anon-coins should have higher market caps. But I think a big problem is people get emotionally invested in their coin.  Its healthy to have competition.  But its unhealthy to have a closed mind because of your financial holdings. Also its unhealthy to make unfounded accusations on other coins just to try to push your own investments or agenda.  Maybe you held some Shadow before and have dumped it, so now psychologically you want the price to go down.  Believe me I have been there before.  But its best to squash all that, and just support the coins because of the tech, and freedom, and privacy they allow.  Price matters, but its not what matters most.

Please tell us why its not the best anon, and what anon-coin is better and why.  So you are admitting that what Ryno did is "neat", yet its a scam because the price is where its at?  Do you realize how ridiculous you sound?  You also really don't understand markets much.  A market with low liquidity like this is going to have a lot of volatility, but the upside potential is huge.  To say its a scam is a horrible lie.  You think its a scam because the price is low and will never go up according to you?  That is a fallacy in of itself, but also you must have a crystal ball to see the future.  The price is already rebounding, looks like it found the floor.  But the price does not matter anyways, what matters is tech.  The real scam coins are the ones with inflated fake prices.  To call ShadowCash a scam simply because the price is where its at is preposterous.

I love the trolls who just call scam with no evidence at all.  Say what you want about ShadowCash.  If you don't like it fine.  But calling a scam with no evidence is pretty pathetic.

If we can design an appropriate marketing campaign I would also be willing to donate.  I know some crypto news sites offer paid articles.  Would be nice to get on Coindesk I think.

Hey guys, bad news kind of.  Kristov Atlas e-mailed me back.  He said he hasn't looked into ShadowCash much.  And he said he accepted a job recently, so he doesn't have any spare time to look into ShadowCash at present unfortunately.  He did say however, that it looks cool and he will bookmark the links I sent for the future.  Oh well, hopefully we can find some other avenues to get ShadowCash the proper reviews it deserves.

I sent him an e-mail telling him about Shadow and asking him to check it out and give his opinion.  I sent him a bunch of links to white paper and CoolStoryTeller's slide presentation. Also I asked him about a donation address.  Hopefully he will get back to us soon.  I am willing to donate, hopefully others will join in.


  

What are some avenues we can spread the word about ShadowCash?  Does anyone have twitter?  Maybe contact Kristov Atlas and ask him to review the code: https://twitter.com/kristovatlas

I know the DarkCoin people donated thousands of DRK to Kristov Atlas to review their tech and he reported it on his youtube show "dark news" on the world crypto network channel: https://www.youtube.com/user/WorldCryptoNetwork

He has even been on some mainstream television shows like Glenn Beck before to talk about Bitcoin also.  He is big into anonymity, and he has a website: http://anonymousbitcoinbook.com/ 

Here is his about me section: http://anonymousbitcoinbook.com/pages/about-the-author

I have heard him talk about other anonymous coins.  I am going to try to e-mail him about Shadow and get him talking about it.

Is a pump group unethical?  What if we just decided to all pump the price to 40,000 satoshi on January 7th?  Hey it worked for paycoin they just claim their coin is going to be worth 20 dollar, and bam the market eats it up.

CoolStoryTeller made something similar to this a few days ago.  I think its pretty good, check it out: https://docs.google.com/presentation/d/1yX2jN618Rnzs4g2ri_utdKdHbny6-xnRcPhOuhLNGB0/edit?pli=1#slide=id.g577a31a2a_086

Don't worry about price guys.  Stop panicking.  I have been watching the market on bittrex, and it really seems like mostly one large holder keeps dumping.  Maybe its a few different people, but I think it might be one guy.  Hes been waiting for larger buy orders and filling them all at once with like 25,000-30,000 SDC sells at once.  Its been happening for days. Seems like they have several hundred thousand SDC or maybe even millions.  Several hundred thousands of SDC have been dumped.

Just hold tight and don't worry though.  People are scooping up these cheap coins.  Do you realize how little liquidity is in this market? I am not sure exactly how much is needed, but possibly all it takes is like a 20 bitcoin market order to send the price to new highs.  All it takes is one whale to come in and look to buy a bunch of SDC.  Just hold tight, this project is going to get the attention it deserves.

Ryno seems like a cool guy, lay off him.  His job is to code, and not PR.  Look how much effort the devs have put into this coin.  That speaks for itself.  I believe the flu story, because the guy was probably working his arse off getting shadow send v2 ready and it takes a toll on your health when you don't sleep.

As for me, I am scooping some cheap coins.

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.

There have?  Which ones?  I know Monero does not have a GUI wallet, but only a web based wallet.  But SDC wallet is amazing, with many advanced features like encrypted chat, and soon to be a decentralized marketplace.

Can anyone offer insight into ring sizes when sending to and from shadow?  I guess ring sizes must be chosen to be smaller now because the network is still small? Does ring size affect anonymity/privacy?  Sometimes it won't allow you to send because it says not enough anonymous outputs exist.

Also I noticed when sending from Shadow back to SDC, you must always use a stealth address, is that correct?

I want to vote for ShadowCash (SDC) also.  But I don't know how to vote, is it over?

For those who don't know ShadowCash yet, this is how it works: https://docs.google.com/presentation/d/1yX2jN618Rnzs4g2ri_utdKdHbny6-xnRcPhOuhLNGB0/edit?pli=1#slide=id.g577a31a2a_086

Also white paper is here: http://shadow.cash/downloads/shadowcash-anon.pdf

Also ShadowCash has the first GUI wallet for a cryptonote based anon-coin.  The wallet is amazing and has an encrypted messaging system called ShadowChat built into it as well.  They plan to add voice, video, and file support in the future too. The devs have also created the first ever proof-of-stake Android wallet.  Also the devs have decided the next implementation will be a decentralized marketplace inside the wallet, kind of like OpenBazaar.  Yet the anonymity SDC affords over BTC offers even more potential for this new marketplace.

Pretty cool project for the lack of attention it has gotten so far.  Check it out: http://shadow.cash/

Here is a great presentation, thanks to CoolStoryTeller: https://docs.google.com/presentation/d/1yX2jN618Rnzs4g2ri_utdKdHbny6-xnRcPhOuhLNGB0/edit?pli=1#slide=id.g577a31a2a_086


Hopefully it makes it easier to understand.

Seems pretty good as long as you don't do anything foolish to expose your amounts.  Or alternatively, I think you can just send some of your shadow tokens back to SDC and then use the SDC to pay the merchant and it seems just as anonymous.

But timing also plays a role as well.  Its probably best to have a pool of shadow long before you have to spend or transfer any back to SDC.  The longer you wait before changing back to SDC, the more anonymous it seems to be. But as the network grows the anonymity will improve as its easier to blend in with the rest of the network.  Also if you have super large amounts of SDC, then this is going to stick out on the network, so better to keep transactions smaller.

Also, alternatively you could wash the funds by going into Shadow, then back to SDC at some future time.  You could prepare pockets of SDC ready to spend.  I find myself doing this with Bitcoin.  Cleaning the coins, then setting up a few pocket addresses that can be used for spending at different merchants without linking them together.  Then if there is any change in the pocket, you could send it back to Shadow stealth address.  Would there be any problems arising from this behavior?  Is it safe to send the change back to a stealth address that already contains shadow?  

But also it seems the more shadow that exists in the network the better the anonymity.  So it may be healthy for the network if we all keep a good percentage of our coins in Shadow all the time.
