so you are saying rox will be back on bittrex in 48 hours?

im not a rich guy, but i believe in your coin and invested about 5 btc. i dont want to cry here, but damn for me this really is a lot of money!

i know there are always risks when investing in coins, but this is a whole new story.

so have i lost all my money or will rox relaunch on bittrex and other exchanges?

Hello

Our dev has applied the changes to the network and we are waiting for Bittrex to reactivate the market. You have invested 5 btc at a higher price? That is a lot of money. I will make sure you don't lost a damn penny and this is my personal commitment to you.

This has been a PR disaster and a total fuckery with our own resources/ our own time - your money, and your time.

We are thinking of holding a Skype session with investors to clear the air, we are ready to talk to you with our own voice and hear out your concerns.

Dyffy is a legitimate start-up with an extremely talented/skilled development crew. I put my real life credibility on the line and requested them kindly to collaborate with us. After the first initial wave of FUD they were extremely discouraged to work with us and I pleaded with them to continue. They were planning to integrate ROX with soundcloud API in a very unique way however they could not damage their own credibility by associating with ROX after that entire FUD storm.

I had already planned to tell the Dyffy team to separate as I could not bear the thought of the embarrassment that I would face if those in this community engaged in an assault against them as well.

Lets arrange a skype session, get on and talk this out. Our dev is in another timezone and comes online from around 6 PM PST on wards. As soon as Bittrex enables the market and he comes online he will be implementing new technical changes.

I am not endorsed with CAM, I have never heard of it until people started speaking about it last night. I do not care about it, I will bring ROX back up no matter what.

Hope you can recover this coin soon... Otherwise everyone will call you a scammer.
Let us know when the skype session starts.

hi all,

we suspended boostcoin deposit due the 51% attack we encountered.
we have solution for it now. the deposit will be reenabled very soon once we the solution is implemented.

thanks a lot for your paitience and supports, and many thanks to mammix2 for the help he offered.

大家好。

之前因为51%攻击的缘故我们暂停了 boostcoin 的充值,目前我们已经有了解决方案。

谢谢大家一直的关注,也谢谢作者 mammix2 在此次事件中对我们提供的帮助。

LOL. It is not possible to get a 51% attack on boostcoin, as that means 1 person owns 51% of all staking coins, which has NOT happened.

i hope mammix2 gives up on your exchange as you seem to be very incompetent.

Interesting to know that a PoS coin was attacked. It is mostly likely to be a problem of BTC38's deposit system itself. If it were a real 51% attack, they would not be able to come up with any "solutions"...
However, LOL, someone does own more than 50% of this coin Cheesy. It is BTC38 itself! They have about 9,000,000 coins...

hi victzhang,

thanks a lot for your great comments. as i am not the technical type of person, so I am not very sure about the very reason how we are attacted. I'll consult our enginner to get more information about the problem we were in.

i also hope mintpal will add boostcoin. a coin with more liqudity is good for all. not only the supporters of the coin, not only the exchanges, but also the coin it own.

have a nice day.

Glad to see your reply here. Your customer service really deserves an A+ rating Wink
Hopefully you have fixed bugs and built a better deposit system. The fast deposit was the reason why I like BTC38.

By disabling deposits (or making them very slow) without a good reason, people may think you are trying to manipulate the price, especially in this case you are almost the only major exchange (actually > 80% of total coins are on you exchange). This is really BAD.
I hope this will never happen again.

Re: Quark investors - Quark information on cycles and the push to move towards PoS.
by
victzhang
on 31/05/2014, 16:21:48 UTC

The problem is fundamental and will stay long-term, so the solution must be fundamental. I think the only viable option is Proof-of-Stake (PoS), the form of mining when a probability of block generation increases dramatically with increase of coins in the wallet of miner. TO day this technology has already proven itself with a several years of operating in probably a hundred of coins. I know no serious issues reported or acknowledged security concerns.

Moreover, PoS is viable economically, as it reward long-term coin supportes and provide income on capital. Also PoS stimulate people to maintain full nodes which favorably affects network integrity and security.

Still, PoS is not ideal because it give a significant share of block and coin generation to coin bags with large wallets. But it could be adjusted to reduce such factor. For example the network could provide even tiny amount of coins generated this way and the process will be still continuing since the costs is almost zero. Or amount of PoS generated coins and/or probability of block finding may be depend nonlinear from wallet. Anyway we could find some intelligent and economically justified solution.



What is needed is an algo which will assess a penalty (a drain) against any wallets holding excessively large stakes in the coin. This algo would constantly evaluate and be aware of wealth distribution on the whole network based upon activity recorded in the block chain (pseudo-anonymously).  When the size or advantage of a wallet, or a quorum of wallets, or a "neighborhood" of wallets, reaches a certain threshold or relational structure, then the algo will trigger the "fission" of the coin balance (a small fraction of it) to occur in the designated penalty wallet(s), while the network makes corresponding microdeposits in another designated set of wallets, the beneficiary wallets.

A Fission event may (A) create new coin and/or (B) deduct existing coin.  A Fission event occurs, for example, when one or more stakes becomes "too big," or an oligarchy of stakes becomes too entrenched.  Fission causes the dispersal of coin from the big stake(s) into and among wallets deemed worthy of being beneficiaries.  That opens a wide door, doesn't it?

Fission may accomplish wealth redistribution, or not.  Its up to the devs and the market to decide which fission regimes are the best.  

My preference is to have fission deduct from top stakes and drizzle the harvest into every other wallet on the network in statistically-defined patterns and portions.  

This "fallout" or dust caused by fission can be distributed randomly in all wallets or apportioned methodically into the appropriate beneficiary wallets.  Different coin developers can compete with different coins defining different ways to determine which "standards" and wallets are "appropriate."  It would open up a whole new generation of PoS coins.  

To sum up: In the proposed "fission" mechanism, whenever the algo determines that a critical mass exists in one or more wallets, or that the time has come to forceably reshape the wealth distribution profile of the network, the stakes in the one or more wallets undergo "coin fission," and each stake blasts a calculated sum of coin out into the community to be received however the devs have arranged it. The dynamics of any coin's fission rules can be customized and finely tuned.

And importantly, stakeholders can reasonably predict the consequences of holding a fissile coin, because the terms and criteria are published; however, stakeholders can never predict the precise timing and exact cost of any one fission event (so they cant avoid it). Thus they must acquiesce to the "stake tax" when investing in the coin or they must go find another coin to parasitize.  Still, in a fissile coin, the largest stakeholders do gain enough steady growth overall to compensate and reward them for remaining dominantly invested in the coin.  

My vision of Fission is that it tickles the big wallets more than it mauls them.

Thus, the above concept is a suggestion for implementing a "coin fiission" algo that might save us from the current doldrums of the "gotto go PoS" days of altcoins, where the imperfect infrastructure of the digital economy is selecting strongly for PoS algos even though we may be better off without much PoS.  

The proposed Fission algo will operate upon wallet balances that reach a "critical mass," or throughout a network when it starts dying for lack of liquidity due to excessively large stakeholdings (e.g., high coin age).  Fission imposes a size-dependent cost upon the largest and laziest stakeholders and it makes offsetting deposits in other wallets according to variable rules and goals.  This will promote liquidity in PoS and will smooth out the rough edges of wealth-concentration patterns that would otherwise characterize a mature PoS network.  


Got it?  Great.  Have a beta version in my inbox by tomorrow...

Your comments and criticisms are most welcome...

However most top big wallets belong to exchanges... See some good discussions blow:

PoW coins with low/no block reward have been shown to not work. A recent failure is Coin2, which was under massive attack and had to implement PoS after that. The attacker even posted in the ANN thread and claimed that he earned 20+BTC by 51% attacks. Considering Coin2 only has a very small market cap, 20BTC is a huge number. Quark could be the next Coin2 if we blindly believe Quark is unique and shouldn't be changed in anyways, and don't take any measure to increase network security.

Not the best example.  Coin2 PoS was 51% attacked.

ha ha..

That simply shows the fact that implementing PoS and not asking people to open their wallets do not work.
However, it is WAY easier to encourage people to open their wallet than to mine. For Quark I don't think it's a problem because there is a strong community behind it.

quark is just fine. Stop making all coins the same. Quark has been copied many times - because it is good. Please no pos. Pos is more inflation and reduces the value in the long run. don't kill quark with pos. Thanks.
Have some patients with it and improove otherwise. do not dilute scarce coin.

PoS will not make Quark more inflationary. Currently Quark has a 0.5% inflation every year. We can split it as 0.25% PoW inflation and 0.25% PoS inflation. PoS will NOT kill Quark; instead, it will save it from attacks.

Network security is a very important issue, and PoS is an efficient way to solve this issue. With pure PoW, people has to set up miners to protect the network; given the very low block reward, a smart person doesn't want to mine Quark because the mining income can't even pay electricity. With PoW/PoS mixed, people can simply leave their wallets open to protect the network at a very low cost.

PoW coins with low/no block reward have been shown to not work. A recent failure is Coin2, which was under massive attack and had to implement PoS after that. The attacker even posted in the ANN thread and claimed that he earned 20+BTC by 51% attacks. Considering Coin2 only has a very small market cap, 20BTC is a huge number. Quark could be the next Coin2 if we blindly believe Quark is unique and shouldn't be changed in anyways, and don't take any measure to increase network security.

Low hashrate keeps investors away. Currently the hashrate is only about 400M. At this hashrate an investor is getting worried because one could lose his/her investment after a attack. This is definitely not good.

PoS is stronger than you think. I know recently there are some discussions on whether PoS is safe enough. Someone doubts if PoS provides enough protection. Yes, PoS could be attacked even only with 1% of the total coins, but it will happen ONLY IF very few people are connecting their wallets to the network and the active stake on the network is less than 1%. PoS can be 51% attacked if the attacker own more than 51% coin-age than the "active" coin-age on the network. We can simply encourage people to leave their wallets open when idle to increase the active stakes on the network to gain enough protection, much easier than encouraging people to fire up their equipment and burn electricity to mine. (Added on 05/31)However, implementing PoS and not asking people to open their wallets do not work. Coin2 is still a bad example here since it was said to be 51% attacked even after PoS implementation.

Price increase will not solve the security issue. If we do some good promotions and more people are buying (increase the price), the hashrate will go up as a result. Promotion is important; however, when the price goes up, attackers also have more incentive and are willing to pay more to do the attack since he can earn more after the attack. If price and hashrate increase at the same time with a similar scale, network security is not improved.

So you know and accepted that Darkcoin has instamined ~2 millions ?

Why wouldn't I accept it? I had the chance to buy the instamined coins for 0.00008 but I didn't. You know why? Because I thought the spread was ridiculous. Want to buy orders were at 0.000025 (as in PMs / thread) and sell orders were 0.00007x - 0.00008x. I said screw that, it's like 3x... Then I watched it go to 0.000180 as orders were coming through to buy massive quantities and people selling them thinking "wow we are damn smart, hoho we unloaded 10 BTC's worth of dark on the whale buyer"... and then it went to 0.0005 and they stopped laughing... and then some sold again, and the laughter was over as buyers bought it up all until 0.002.

In this crazy world, people don't care about instamine or premine, don't care if it is a scam or not. They just want to sell their coins to someone else at a higher price. Scammers know this well.

He probably had enough money to start up this coin Darkcoin, and paid some others too do it big time with money.

I believe this is something closer than ever.

I was on www.darkhack.com and checked the site, and was robbed 0.75 BTC out of him, probalby im on the trace to take him even bigger with darkcoin coins.

Quark is super undervalued.. the haters are the ones who began chasing it when it got hot and then try and shit on it saying it was "PRE MINED BRO!!!" which is total bullshit, it was mined over a short time but wasn't pre-mined at all.
And the same people will chase and praise it when it become hot again.

Kolin, I'm actually a supporter of Quark. But right now we are quite a weak and anyone could easily destroy Quark both with market manipulations and 51% mining attack and it will be cheap for them. Let's admit it and work this out. On the other hand Quark is the only coin I know made with use of market and macroeconomic theory and human experience in this field of knowledge. Quark is a quality work on the mistakes which appeared in bitcoin protocol and economics in recent 5 years. Since that, Quark has the best fundaentals among cryptocurrencies to day. Moreover, developers and community know that the way to success don't lay through painting doggies on cars but through real work like seeking pertnership with game developers. Only a few people in whole crypto world understand it (Charlie Shrem, Tony Gallippi to name a few).
What we see now is a wild market, when a really large money belong to those who just was in the right place in the right time. From time to time it happens in the real world, the great example is a 90s market reforms in Eastern Europe or Latin America. Huge fortunes fell into hands of yesterdays ordinary engineers and workers and many of them don't know what to do with them. Look at the hundreds of jackpot winners who lost everything in months and returned to their few-dollar-work. Money leave the hands of those who dont deserve them. We can see it in cryptos and Quark right now. People with millions of Quarks just see a decline in price and Doge or Dark hype and pump and decide to quit the market. They just don't understand what fell in their hands and don't know how to grow their fortune. Yeah better to join some hype sit and wait when someone took you to the moon where you will be R.I.C.H. For a pity on their way they are able to do much harm to efforts of those who actually trying to do something usefull.
Microeconomic theory proves that free-market equilibrium is Pareto-optimal (1st Welfare Theorem) but don't say when the equilibrium is reached. I believe that no faster than inflation hits 1-2% range what happens for bitcoin and similar coins in 10 years since the first block. Quark could do it much faster maybe in a year or two, when big wallets either lost their coins or prove they deserve them. All the mining issues will be solved in prices 20-50 times more than present which I consider not only possible but inevitable.

To sum up, Quark is not for those who seek a coin which allow looting itself by mining and ineffective distribution model, and not for those who scour a quick buck in a matter of weeks. These kind of people will try to crap it, cause they just don't see a sence in its existence. Quark is for those who are willing and able to work and understand how to move the community forward or at least trying to become such. For these folks Quark is the best platform for now.
That's what me, Kolin and others are trying to say, despite some controversions on a few technical issues.  Roll Eyes

Well said.

FACTS:
Blackcoin is fully mined within the first week.
The author of Darkcoin insta-mined 30%-50% of existing coins within the first few minutes.
Darkcoin's so called DGW difficulty adjustment algorithm is intentionally set to increase difficulty slowly after the initial launch. The first 1000 blocks are generated within one hour, and each of which has a block reward of 500. Remember currently Darkcoin block interval is 150s and block reward is only 5.

Why people say Quark is a premined scam coin, while they give Blackcoin and Darkcoin so many credits?

IMO, most coins launched after last December are scam coins. Their authors created these coins for cheating people and making money.

Quark is one of pioneer CPU coins. It was so cheap before and thus was manipulated by some Chinese whales last December. Right now most speculators have left the market and price is stable. There is nothing wrong with Quark itself.
