hi i have problem with zcoin pc wallet its not been synce and processed stoped on 670 of 40k from last day ! may help me please how i can fast download ?
Get a blockchain downloaded: http://znode.io/hi thanks for reply me. how i use that ? i extract Blocks and Chainstate Folders to Users\Username\AppData\Roaming\zcoin ,its right ? i doing that but Zcoin wallet run and stop on Loading wallet.. what i doing now ? Remember to make a backup of wallet.dat under Users\Username\AppData\Roaming\zcoin, and then remove everything except wallet.dat (I guess you didn't delete files, that's might be the reason of errors), then unzip block chain files into that. Close the qt-wallet before you doing the above, and then launch up the wallet. I haven't done through the above though, but believe should work.

You are just a worthless liar J_A_Bankster, you wrote "zcoin remained relatively stable", no it didn't it dropped from $19 to about $10.50 at low point. Now it's around $11.50. That isn't "relatively stable", and unless you believe your own lies you know that. I don't really mind people like you lying, although when it's as outrageous and blatant as this I'm happy to point it out as I have done. Since you asked, yes, I like being me. Why did I post that about the devs doing what I think was a misleading pump announcement of an announcement - because I don't like it. I think it gives someone some short term gain - them? - but it's shortsighted. You build trust and long term significant price rise by doing things the proper way. Dash did this. They started off with an instamine and got hated by everyone. But then they did it right and by the book, and all of the early investors would be extremely wealthy now.
My comments can't influence the market price one way or another. They can perhaps inform it.
Look at you frustrated loser calling everybody a liar lol.. ZCoin recently went from $8 to $18.... and gradually came down as is normal after a pump i might add... Then last week Ethereum - the hottest stock in the world right now - crashed nearly 30% and zcoin remained relatively stable...so where is the lie again? Besides, whats wrong with you little snowflake..? Crypto too hardcore for your little nerves? This is not a game of safe spaces, this is the Wild Wild West of financial investments.. pump and dump is the name of the game... By all means sell everything you own and go sing John Lennon songs whilst writing poetry under the rainbow.... But no worries, you have enough self reflection to understand your brain is not working properly LMAO MTP is underway, it is written in the code..

Poodle you are such a douche bag now leave this thread please.. And just so you understand me, i invested in Zcoin when it was $4,-... these swings don't affect me the slightest at this point.... Given that this is a long term investment and it has been known for months that August-September true maturity in development will commence.. You are feeling entitled and demanded all kinds of things... I truly hope you bought in around $19, let the market humble you with your big mouth Trading wise XZC perfectly follows an upward trend line.... A one day spike to $19 doesnt mean that this must be the norm immediately... Yes Zcoin is holding very strong on support level... Once again VERY STABLE, if you cant see any of this i dont think trading is for you... go find a hobby poodle.. maybe you can walk dogs in the park..less stress for a snowflake like you. This crypto is being coded from the ground up with a small team with relatively minimal resources... This is start up and people investing now are still way ahead of the curve... If you cant identify the opportunity here, then please go and put all your money in Litecoin today, its up 20% Also spend all your money on XBC which is up 50% today... Go poodle buy at the tops you entitled loser buy everything that is green, you will be a millionaire believe me LMAO

I bought at $4.90, why would you want me to lose money? I want you to stop lying and saying the price was stable when it dropped 40% in value. Other than that I think you an I are actually entirely on the same page, I think Zcoin has longer term (1 year timeframe) value. I agree with you about the danger and risk of high value altcoins like Litecoin too. Stop attacking me when it was you who did the wrong thing (lying about the change in value of Zcoin over time). Poodle you are such a douche bag now leave this thread please.. And just so you understand me, i invested in Zcoin when it was $4,-... these swings don't affect me the slightest at this point....

It's a 20% fee !!! 223200 coins minted per month x 0.2 = 44640 to the Dev Treasury at a avg price of $12 it's 535 680$ per month. This is one of the reasons i prefer open projects where everything is public. XZC has potential but still a long way to go.

Is there a version of ccminer that supports older gpu's and has lyra2z algo or any gpu miner that supports older cards and has lyra2z algo? Currently no. Lyra2z is being phased out in a month anyway. Currently 4 x GTX 1080 TI will net you around 1.4 XZC a day only.

Very interested in this coin... Can't wait for the MTP implementation.... Can we also have an update for easier mining on the GUI wallet please?

Hmm, but I thought, that MTP was released already, wasn't it?

Uh, I guess not: https://github.com/zcoinofficial/zcoin/commit/bc81678b7f9467fecf64e0a44dba35550e50619fNot just the parameters, but the algorithm just changed this weekend? And no longer follows the paper? How are we supposed to code for a moving target like this? What is going on here folks? This is some serious seat-of-the-pants-nonsense. If you are making changes like this then you'd better not be serious about the height=47500 target, and if you're not then that should be made public. Either way I will be sitting out until the dust settles.

Either way I will be sitting out until the dust settles. Hi mjosephs. Totally understand your concern that's why we haven't released the MTP miner bounty challenge yet. We will be releasing the details sometime this week which should give people more than a month to code miners. The MTP change was meant to address recent findings in this paper: https://eprint.iacr.org/2017/497 which was only very recently released (like two weeks before we released MTP?) and we were only recently made aware of it. After consultation with Dmitry Khovratovich (co-author of MTP), the proposed fix in the paper was not ideal as it used Argon2i instead of Argon2d as there exists strong tradeoff attacks on Argon2i. TLDR version: the paper talks about bruteforcing the garbage blocks until the references to the next real blocks all point to the memory. A solution to this (and simpler attacks they mention) is to embed the challenge in all compression function calls to prevent memory reuse across challenges and this is the reason for the changes in the algorithm which are relatively minor. No planned changes on the block 47,500 switch. We don't forsee any further changes on the MTP algorithm itself. Some of the fixes are in there are to fix the memory leak in the inbuilt miner and not the algorithm which should not affect miner dev.

Totally understand your concern that's why we haven't released the MTP miner bounty challenge yet. We will be releasing the details sometime this week which should give people more than a month to code miners. Dude, this isn't about your beauty pageant. Radical last-minute changes like this guarantee that the best miners will be the ones that exploit some bug you introduced while frantically trying to plaster over another bug. And they will be kept private. Like the last Zcoin issuance bug. And this didn't cause you to reconsider whether or not you understand what you're involved in here? After consultation with Dmitry Khovratovich (co-author of MTP)
... and the same guy who utterly failed to foresee this entire class of attacks against his MTP scheme. Wouldn't it make more sense to gather opinions from the people who broke his scheme? TLDR version:
A simpler way to put it: just like PoS is vulnerable to "stake grinding", it turns out MTP is vulnerable to "DAG grinding". Instead of grinding for a nonce as you would like them to do, the miners can instead grind for a favorable DAG that minimizes the chances of their bluff getting called when they stuff garbage into the Merkle Tree. It's like letting a poker player sift through all the possible future call/check/raise patterns instead of sifting through all the possible hands he might be dealt. Once he finds the "future" where nobody calls his bluffs when he's bluffing, it doesn't matter what cards he's dealt. DAG grinding is still grinding of course and it's still work, but it's not memory-hard anymore -- DAG grinding requires hardly any memory. This calls into question any sort of scheme for validating only a pseudorandomly selected subset of the miner's work. The source of pseudorandomness has to come from the blockchain's blocks, which are selected by the miners themselves, meaning it will always be a potential alternative grinding target. The band-aid hack bears a disturbing similarity to the Proof Of Stake cults lately, who just keep slapping on extra layers of complexity to hide the alternative-grinding problem, when in fact it raises fundamental issues with the entire scheme. the changes in the algorithm which are relatively minor.
... and only fix the most epic and catastrophic attack. All you did was stop miners from reusing work across blocks; MTP is still no longer memory-hard in light of Dinur and Nadler's work, and can be mined using an ASIC with less than a megabyte of on-die SRAM (i.e. 20-year-old chip fabs). By the way I think it's utterly fascinating that Nadler is a semiconductor fab tool engineer/executive rather than a cryptographer ( check out the guy's career history). Dinur of course is a hardcore hashbreaker. No planned changes on the block 47,500 switch.
Full speed ahead, trainwreck ahoy! We don't forsee any further changes on the MTP algorithm itself.
Well since you didn't forsee this one that's not saying much.
