Hi Jack,

when you moved the wallet does it still appear in your Mint transactions? If it appears, it isn't lost but may not have had additional people using the accumulators during that time.
Both transaction IDs don't seem to appear on the blockchain? What version were you using? 0.8.7.8?

I've also lost coins with the Mint & Spend function. I tried one coin and 100 coin tried to redeem (spend) over a month ago

After that I moved wallet.dat file to another pc. I didn't realize it had no confirmations so lost some more coins on that one. They also show as zero confirmations, but on the first pc there is no trace of them even being redeemed.

zcoinofficial
please tell me about algo changes on 47500 block
I ask about fork but nobody tell me
How you will change algo without fork?

50 xzc mints are a particular unpopular denomination I believe there's a mechanism in there that prevents you from doing spends until more mints fills up in that 50 xzc accumulator to improve your anonymity but I'll need to double check with the devs. Remember the anonymity is within the mint denomination.

When I encounter this notification when trying to spend,
"it has to have at least two mint coins with at least 7 confirmation in order to spend a coin"

I usually resolve this by doing another mint of the same denomination and then waiting 7 confirms for that which allows me to redeem my earlier one. As long as the mint still shows in your wallet, there's no 'lost' money unless the mint is completely not appearing in your wallet.

Hmmm. Another one who lost coins.
I need read all posts befor I make own conclusion.
but
Zcoin - new minig algo dosnt help you if it possible to lost one coin.
Cose one coin = 100 coins = 1000 coins wich may be lost , damn
it is about trust

I understand your frustration awill333.

We are trying to replicate your problem here. Trying to actually get an abbreviated version of your problem for the devs to look at cause they're right now furiously finishing stuff up but I'm seeing if I can get Leoreinaux to help out.

Yes of course say 'troll' and ignore when somebody has a problem of course it is the individuals fault because ya'll have had "no problems" that thing must work _PERFECTLY_ right? so i guess you have all compiled it and observed the results to? All being those who wish to attempt to call my a liar or wrong or discredit my statements. I am simply here to let you folks know that the mintzerocoin function lost my 50 coins and you call me wrong? That is absurdly foolish. Thats ok I am done posting here because team Zcoin has failed to provide any sort of response as you can see the silence means they dont know sh*t about what is going on either.

of course the tiny brain will not process what has been presented I have posted for those with any sort of perceptive and reasoning abilities so they can protect themselves.

a f*ckin typo error lost all those coins and you think that I am WRONG? haha if you think that ya'll crazy. This shows very sloppy coding and no audit and I am sure that nobody who has invested has actually inspected the code they just think they will get rich from a tool that never delivered what was promised, a functioning mint zero coin transaction. and so you can obsess with idiotic mtp all you wish to oneday figure out I am right. Have fun guys you wont hear from me again.

PS- I dumped my 685 coins last night and I am ripping all of the zcoin modules out of the software I am creating. I would challenge anybody who knows anything about programming to compile that code and inspect it and then tell me there is no chance that could have happened to me. It's on the blockchain, I have all of the private keys, wallet, proof, etc. Yet there is nobody here even attempting to help me? Where should I write to? The FCC? haha that's the funny thing about crytos NO ACCOUNTABILITY. so nobody cares because they dont want there coins to lose value. I sold all of mine so I don't care at all. And to the fools who think that is a wise choice you will learn the hard way. To any person of intelligence I challenge you to inspect that code yourself and see what a joke it is. Ok thats enough I am over wasting my time with you folks.

No probs here

I, also have had zero probs with the wallet. Ignore the trolls!

I downloaded the Linux wallet tried all the functions, and didn't have any problems, the only thing that I've noticed is if the computer shuts down improperly (eg power outage or wife holds the power button to get the kids off it) when rebooting the function to start the wallet automatically it runs in the background and in order to use it I'd have to kill the process first and restart the wallet. I'd have to say even with this small problem the wallet is always synced when I do restart it. Let me recap that all functions worked including mint zerocoin!!!

Don't understand whats going on. Im sure - somebody come and explain to us this situation.
Cose we wait MTP miner but you , man, talk about problem inside system.
Here is 223 pages. Somebody lost coins?? Cose somebody must see that problem befor.

Just to reiterate, in case my previous posts were not seen by the reader, I had a problem with zcoin the other day. I was testing mint zero coin function from the GUI wallet, I minted two 50 coin increments of zerocoins. One of the the procedures worked fine. I have included the data from both of the mint zerocoin transactions because I am not entirely sure which one was received and which one was not. It is all a bit confusing.. However, I am no idiot and actually I was in the moment of doing testing for software that I am devleloping that was to include zcoin support.

I wrote a post on this forum explaining my problem and instead of receiving any help I was simply directed to private communications and then re-directed to "slack" to talk to "the developer". I did create an account there but now I am having problems logging into it which is also quite infuriating. Did I mention that over the course of loading and reloading and reloading and reloading the blockchain from a non corrupt and working-just-fine wallet I have used well over 30 hours of my personal time. Time which I could have been working on my own projects implementing coins that function as promised. This wallet is nothing more than a piece of beta test software that was unleashed on the public so we could be "guinea pigs". After having a problem logging into slack I have become quite infuriated about this whole situation. I have wasted so much of my time on it now without any consulting with "the developer", that my time is more valuable to me than the stupid 50 zcoins that were lost. That doesnt amount to much more than $300 while if I was being paid even a pathetic low wage for my applied efforts regarding this particular problem it would be well over $1000. (at an insultingly low / hr wage btw).

I am not getting paid to develop zcoin, nor am I getting paid to lose my money and help the "developer" (who is claiming a founders fee of 20%) to make his code better. The facts are simple, I compiled this software from the source code myself as I do with all of the other wallets that I have been testing. The result was a _horrendous_ amount of "warnings" I am surprised it even compiled! They were warnings from broken libzerocoin not my fault. the other daemons I have compiled since was zero warnings. It is no surprise the coin disappeared, I should have realized the score when I compiled.

Why am I writing this text now? There are a few reasons I am wasting even more of my time and haven't quite written this off as a loss yet. One is in hopes somebody can provide me some INFORMATION as to how to GET MY COINS BACK because nobody has bother to do so. I have not had a single question answered, only a redirect to another confounded situation. I believe the answer to my statement of "not agreeing to move the conversation behind close doors" was something along the lines of "we may require your private keys" . And just what makes you think that I trust you, "the developer", or SLACKs unsecured messaging system with my PRIVATE KEYS? Are you all insane or do you think we are all just so stupid we will use software that has 50% FAIL when minting zero coins. Yes, I minted 4 parcels of zero coins two of them were 50xzc parcels and the other two were 1xzc portion. 2/4 (50%) mintings were lost. This is not my fault the wallet is bullsh*t.

I would like to take a moment right now to publically apologize to PLAYING POODLES because I publically talked rudely to him when he was simply expressing the dissent of the slipshod modality being applied by these "developers" and using our loss as their gain. That software never should have been released on the public and there is NO WAY it should have a version number as high as it is. That is EXTREME BETA software AT BEST. It should show up with WARNINGS THAT YOUR COIN MAY VAPORIZE and if so YOU WONT RECEIVE HELP WHEN YOU ASK DIRECTLY FOR IT.
Prove me wrong by answering my questions. WHERE THE F*CK ARE MY ZCOINS? This is more of a public service at this point than an expectation of getting my coins back. I refuse to transmit private keys over unsecured systems and I refuse to trasmit same to parties I DO NOT know OR TRUST.

I was all about Zcoin and I sold all of the bytecoin and every coin that I had to stock up on Zcoin exclusively. I started writing software for zcoins implementation to real world function. I wont mention what I am selling all of my zcoin right now to trade so nobody thinks I am here for the selfish interest. After seeing the code (I am now using) for the daemon compile without any warnings, code that is far more complex, I have much more faith that that software will not lose my coins. AND THEY WARN YOU WHEN THE WALLET IS BETA.

so this is a word to the wise. I hope if you plan on investing in zcoin you try MULTIPLE MINT ZERO COIN TRANSACTIONS because the developers DID NOT SUFFICIENTLY TEST THE MOST IMPERATIVE FUNCTION OF THE WHOLE SYSTEM !!!!

Yes that is severe and all capitals but if you think I am watching clowns throw away my money because they wrote sh*tty code and not complaining about it, that is just crazy.

By the way all of these texts were copied out of my wallet and block explorer today, the 30th of July. As you can see the above address aAXQzvBL56EzkGngZgeQxcBGv9bowY2P5k never received ANYTHING although the wallet claims the coins were sent there it was never verified by the network.

So yes expect to be criticized publically when your wallet is eating peoples coins for breakfast. I am deeply insulted by this event. Not because of my measly loss but because of the potential loss for any and all customers who I would encourage to use the software that was being written who may lose an infinity amount of coins minting zcoin with only 50% success. What possible justification can you have to release a product like that on the public other than blatant lies and promises that it "does work" ?

I expect any data to be presented about this subject to be presented publically. THE PUBLIC DESERVES TO KNOW WHY THOSE COINS WERE VAPORIZED AND IF YOU FIX THE PROBLEM OR NOT.
No, I will not give my private keys to any address. If you have advice for troubleshooting (WHICH I ALREADY REQUESTED), you may provide it in knowing that I am a highly skilled and technically oriented person more than capable of troubleshooting this problem if you have any information that I do not currently have such as where the f* is my money.

Indeed, we ourselves are surprised at the hash rate. Not sure how many other 'CPU-friendly' coins are out there tho.

mabye it's just for thrill of saying they're mining Zcoin

But if they mine pure for speculation why not mine a other more profitable coin and trade them back for more zcoin? Oh well maybe it doenst matter at all since new minging algo is arround the corner but still is a bit strange

oke thanks I mixed things up. first I thought we where already on mtp algo but then I understood we where on a transition algo what gave me the impression that we just switched or something in preperation for mtp what seemed kind of strange in the timeframe but should have read it more extensivly.

Goodluck to all the bug finders!

I thought, that botnets and vps workers do not mining now because of MTP release. And of course if botnets are still available to mining, it will have bad influence to price.
Also one question - any news about Z-nodes?

im mining for speculation mostly as well, tho for me if the price dosent take a huge climb, ill just hold till my "Znode" ROI's me hehe.
This coin's development is still young, and i personally think MTP will bring ALOT of attention to zcoin, the Miner competition is on now so it wont be long now
I use ccminer too ya, there's nothing better i have found, and it's super stable

I know them, top 15 miner in miningpoolhub are botnet or vps worker. They can use many more cpu for mining not need spend money for do that, so they alway live in top 15 in long time and not care about profit because free all
