For more a week, the dev doesn't say something. Is it going to dead?

Did some of you miss the fact that the dev said he was mining solo at the start, yet it was massive hash and the wallet that was mining from block 1 ended up getting some huge number of the coins.. And then they were dumped and the dev disappeared???

Had an odd bug with the windows wallet.  Completely new install, fired it up and it starts to download the blockchain. I rename the main address and write the info down.  I create a second address and write that info down.  Then I go to create a third address and when I click Ok, it just hangs so that I end up having to just kill the process. I start it back up again, it starts to download the blockchain and I go to try and create that third address again and the same thing happens. Tried a couple times and then gave up. Figured it might have something weird to do with the fact that it was a completely new install. So I started it up again and just left it running and waited for it to finally download the entire blockchain. Once it was done, I was able to create that third address without any problems.

Thanks for the bug report Viper. By chance do you have a Twitter account? I'll shoot you over a tip via the Twitter bot. xD

Nope, I don't have a twitter account.  Keep meaning to get one "just cause" but it's not something I can see myself using that much.

Most likely the current pump is a combination for 3 things. The pump a week or so ago was probably mostly due to the merge mining with LTC.  Now it's probably due to the merge mining, the halving that's going to occur within the next week or so and the gocoin paypal thingy.

There could be another reason though, the falling BTC price.  It's probably in the miners best interest for Doge to be much higher so they can offset BTC losses with Doge.  But you'd have to ask miners if that would be true or not.

Making it hybrid sounds like a good idea. I'm not sure what Devs think about it

He's said he's in favor of lowering the block reward and extending mining.  He's also said this:

Personally, I would like to see PoW remain an option even after said total is reached in order to help process transactions and alow miners to collect tx fees.

What are the pros and cons to lowering the reward? I'm trying to get a grasp as to what this would mean for the community, the coin and my investment. Thanks guys!

Lowering the reward involves extending the mining period as well so there's a few benifits IMO.

1. More interest in the coin, more people involved etc which is better overall as it leads to a more active market, more people wanting to use the coin etc.

2. The network is more stable when the coin is being mined. Take a very rare coin like Firecoin that's only PoS. They have a problem there because not a lot of people are staking and so transactions can take a long time to occur.  But in another rare coin like Uno, they still have mining and thus transactions are faster.

3. Although staking creates new coins, people tend to horde them and they don't make it out into the market. On the other hand, miners want to sell their coins and so there are fresh coins coming into the system constantly which also should help to spread out the distribution more.

4. Less coins means the price should stabilize, not be susceptible to as many "large" dumps and actually go up as time progresses.

As for cons, the only thing I can really think of is that as long as the coin is being mined, it could be susceptible to a 51% attack. Once PoS is implemented though, that should help to alleviate that somewhat.  Maybe if someone else knows some other Pros and Cons they could outline them.

So are you for or against POS? Seems like the con would outweigh the Pro there..

Not sure exactly what you're asking since going PoS either does away (sort of as it's just a lot harder with PoS) the 51% attack issue if you don't have mining, or it helps to alleviate it by having people staking.

But I'm for having a hybrid PoW and PoS coin as I believe the combination creates a stronger coin in the long run.  Peercoin for example is a hybrid.

I've got a few question about this coin and hopefully someone can give me some answers.

1. Where's the source? Looked at both threads, the official site, the wiki and either I'm completely blind or is it not open source?

2. What method does the PoS use? Like peercoin with coin age? Like NXT? Or like the newer BC PoS V2 or Reddcoin PoSV? Or maybe something unique?

3. Is the coin based on ZeroCash? From what I've read and with the upcoming implementation of zk-snarks it would appear it is.

4. Assuming it's based on ZeroCash, I'm wondering about:

4a. "They used a brand new technic called SNARK, which has certain downsides: for example, a large initial database of public parameters required to create a signature (more than 1 GB) and the significant time required to create a transaction (more than a minute)" - What does all this really mean and what, in terms of practical use, would it mean to users?

4b. "Another important note is about trusted setup in Zerocoin. In easy words the whole system is based on some secret values nobody should know (for example, this secret allows to make a double spend). How to acquire these values? ZC devs says: we can generate them and then "forget" OR we can implement the special algorithm to do in a distributed way at the system start (everybody know only his own part of the secret)." - does this issue also exist in Zerocash and (if Shadow uses it), ShadowCoin as well?

4c. "The proofs of Zerocash can be computed by a i7 single core 2.7 GHz CPU in a matter of 3 minutes" - What exactly are these "proofs" and again, what would this mean to regular users?

I really don't understand fully the difference between Zerocoin and ZeroCash etc so not sure if all this really would apply but maybe someone in the know could educate me.

Hi Viper

1. The project is open source, the link for the repo is on the ANN theres a little icon for Github. I can see how you would miss it though., we should probably add a link to it.  https://github.com/SDCDev/shadowcoin
2. Shadow is using coin weight/age. Any change to the PoS scheme will happen after zk.
3. ShadowSend is based on a combination of dual-key stealth addresses and zero knowledge proofs. The underlying technology in ZeroCash is zk-snarks, but the initial setup of the parameters in zerocash requires trust. Shadow is using its own zero knowledge scheme (proving a statement without revealing any information) and our setup doesn't require trust.
4a. In the WP they are referencing the initial parameters of Zerocash. Our system uses a different setup, so that issue only applies to ZC. All this translates to for the end user is that the ZC opts for a trusted setup.
4b. This is a non-issue because of 4a.
4c. https://self-evident.org/?p=995
Here's a detailed video covering the differences:
https://www.youtube.com/watch?v=FXU65XsLiFk
I've attached this pdf for zero knowledge in laymen's terms: http://pages.cs.wisc.edu/~mkowalcz/628.pdf

Awesome, thanks for the details answers.  Yeah, now that I look back at the OP, I can see the source icon there.  I just assumed those were all some sort of wallet downloads lol

So I was just looking up "dual key stealth" and came across DarkWallet. Then I came across this post of yours which actually laid it out a bit more clearly for me.

https://bitcointalk.org/index.php?topic=700087.msg8153845#msg8153845

Am I correct if I were to say that ShadowSend is an improved derivative of DarkWallet? Or maybe that's not really fair to say as I can't figure out who actually implemented what first. lol

So right now there seems to be I guess 4 anon "methods".  We've got Darkcoin which one could argue isn't all that trustless given you need the masternodes.  Then there's CN which, near as I can tell, is generally perceived as the only "true" anon implementation out there.  I found it interesting though that one of the CN guys seemed to be saying ZeroCash was a more advanced method although I'm not sure if he also meant better. And then there's some other coin that will remain nameless that seems to be implementing some derivative of CN which they claim will resolve at least the blockchain bloat issue of CN coins.  The Monero guys recently put out a white paper outlining some issues with CN that could potentially result in exploits.

So, if we assume that CN is the "best" currently despite some of it's issues, what makes ShadowSend better and what are some of the issues with it. i.e what are the currently known Pros and Cons.

Hey Viper,

We're actually working on a overview that will chart the pros and cons of each unique anon protocol. Approaches that don't use zero knowledge either mix or mask the transaction by using nodes, pools or group signatures. ZK protocols make the transactions invisible in a way that only the sender and receiver know about the transaction. It would be the same as thinking of paying someone in cash and not keeping a receipt. The only people who would know about the transaction is the buyer and the seller. The other approaches like mixing or group signatures could be looked at as paying by cash, but using something like western union or a money order to facilitate the transaction. Although the transaction is technically cash there would be a way to figure out and/or trace the transaction some harder than others.. ZK and it's variants are the closest thing to a cash transaction in cryptography.

A couple benefits of Shadow over CN would be a compressed blockchain vs bloated one. Shadow has a Simplified Payment Verification (SPV) system in place with ShadowLite (thinmode=1) that already helps reduce the bloat.

Ok, thanks.

what was the block reward? just curious

If you're refering to the PoW period, it was 1 for some period of time after launch and then 400 until the end of PoW

Code:
    if (nHeight <= 0)
        nSubsidy = 0;
    else
    if (nHeight <= LAST_FAIR_LAUNCH_BLOCK)
        nSubsidy = 1 * COIN;
    else
    if (nHeight <= LAST_POW_BLOCK)
        nSubsidy = 400 * COIN;

last fair launch block until what height? 0-1000?

Code:
static const int LAST_POW_BLOCK = 31000;
static const int LAST_FAIR_LAUNCH_BLOCK = 120;

Clock failed and the price fall, simple as that. Think Stealthcoin as Darkcoin and Litecoin then you will win. You can't be a sore loser all your life, almost all flippers are sore loser included yourself. Most of us here already 10x or 12x profits.

lol..  Ok man.  Whatever you say..  lol

I guess what you really mean to say is that you're one of the P&D guys as that's the only way you could be at 10x 12x profit.  And I don't mean holding coins in the hope it won't suddenly crash,  I mean actual cash in your pocket.

Bro, 'PnD groups' as you call them are the people who grow a coin. Their strategy does not include dump. Dumping is what people like you do, and you're kind enough to admit it. A good coin is easy to grow. Cloak WAS a good coin, and it turned crap - it was not killed because of PnD. Look at the Xst chart - large dumps have not killed demand.

You think you're pretty smart, but it's your kind that are the enemy to a coins long term growth and health.

"Bro". By definition P&D groups grow a coin and then dump to take their profits and move on to the next one.  As for volume on this coin, it's because of the P&D groups and the bots. When the P&D guys aren't active and you take out the bots, the volume isn't as high as one would think.  Look at the dumps that have occurred on this coin.  That wasn't me.. That was the P&D guys.. If the coin had been left to grow naturally, it would be much more than it is now.  It was held at 9k (any time it tried to get to around 10k or so it was dumped) for what, a week or two and then allowed to grow for this mintpal thing. Then the dump.. and now it will be allowed to grow again for StealthSend and then another dump.  This isn't real growth.  It's not because of the coin or the devs itself, it's pure manipulation for profits by a select few at the expense of those that don't know any better..

BTCwriter, just read the previous posts from him to see that he actually invested in the scam ltcd and only appears here to spread soft fud with a pseudotechnical blablabla moved by envy since the days when he still believed in cloak LOL

I don't "invest" in any new coins, I simply trade as they're too unstable, unproven and far too risky especially given the people involved in most of them.  Maybe one day there will be a coin worth believing in but I have yet to find one besides the old established ones.
