Such a severe bug could easily destroy the coin, if it not already did so.

if the dev know a little about logic, they will realize that the hacker has stolen from them not from the community so in my opinion the should destroy 370 000 XZC send them to a vanity wallet a wallet without private key. that will bring a little confiance in the dev.

Please enlighten the devs how to destroy it when the coins are already sold on the market? No one has absolute control of that hacked coins now, how to gather them in one place and burn ??

its simple destroy the same amount of stolen coins from the dev wallet, you are payed the 20% of all mined blocks for good development if you fail you should pay, i'm i wrong ?

the stupid wallet is stuck at synchronizing the network, like at 4%. How I'm going to send my bittrex coins to that wallet if it can't even sync

ya i have to admit im not sure WHAT this team has been working on all they seem to care about is tweaking the algo for cloud miners over and over. tho its alot more GPU friendly which i like, but damn, FIX YOUR WALLET ZCOIN :/ most cant even store their coins long term, how will the community support holding? Sad

He means that, the devs must destroy 370 000 XZC from their own funds as compensation for the stolen ones, just for the good for XZC coin itself.
Problem is, i don't think they have that much XZC yet.

i agree this must happen

Is there a way wallet could synchronize faster? it will take days.

it is a good idea

@dev : any news of the compiled runing file for Ubuntu of the new wallet ?

Apologize for our delay and thank for your support. Here is it

No problem :-).
Good job, works fine with my configuration.
Thank you (the FP author can put the link in the FP).

As for price pressure, I don't think we should comment too much on price as that is not really our job and markets are fickle though the immediate aftermath really wasn't all that bad.

We have a lot of good urgent work ahead of us and the first priority being putting in checks in place and code review so that something like this doesn't happen again. We do of course have other features and plans lined up but let's focus on one thing a time rather than stretching our resources too thinly which was one of the reasons the bug occurred in the first place. Would be foolish to repeat that mistake again as this is a long term project.

what is it?
https://chainz.cryptoid.info/xzc/block.dws?21894.htm

Sooo... if fork is at block 22,000, doesn't it mean the bug is still there until the block 22,000? So coins could be still minted and dumped? Do I miss something?

still something wrong with the rich list on https://chainz.cryptoid.info/xzc/#!rich
there's no zcoin blockchain showing the real number of coins circulated. I think the devs should pay some collected coins to find some other coders to do this.

i think you need to go do some reading about what libzerocoin actually is and does.
your comments literally make you look retarded.

also:
http://www.newsbtc.com/2017/02/19/zerocoin-updates-about-a-bug-in-the-implementation-of-zerocoin/

well, smart guy. is there any correct blockchain explorer without showing the wrong richlist? i find non.
someone has had found something wrong with the rich list last december and reported to the devs, the devs said---something wrong's with the blockchain explorer...
well, it's ok, the chainz's doing this zcoin explorer for help and for free, there's nothing to blame. and i just didn't get it when the devs found something went wrong with chainz explorer, why didn't they just build one official explorer themselves. until now, after we just paid half a million dollars for them, still there's nothing.
possiblly the devs are toooooooo busy, so spending some coins collected to recuit some new coders could be a much more feasible plan.

sigh.
again.
once coins have been minted to anonymous; you arent able to simply 'check up on them via richlist'.
as is the entire underlying basis for this technology.

Our dev Aizensou is working on our own offcial block explorer which will also have in built checks to detect such abuses much quicker.

Chainz were paid to host our block explorer but of course deep customization is not expected. @fairglu has been pretty responsive and awesome.

It seems zcoin is decreasing more deeply. There is no buy support and the volume is still down more.
Maybe the big whales have left this coin because of error typing in the code. Is there any new plan for this coin, DEV?

I see the price is deeply down but that is good chance to buy more cheap zcoins. I expect it will decrease at 0.0006btc then I will spend all my bitcoins to catch it up immediately.

Sometimes bug happen. nothing is 100% safe, in crypto as real life.

i think u've just mistaken zcoin for zcash. and you cannot explain why the devs finally found something wrong with the incorrect circulating volume. the devs gave explanation to this comic entry level error as following link and they said:
https://zcoin.io/language/en/zcoins-zerocoin-bug-explained-in-detail/
"
How we discovered the bug
Slightly before midnight on February 16th GMT+0, during a check to analyze how widely used Zerocoin transactions were in Zcoin, we discovered that the total Zerocoin spend amounts did not tally with the number of mint transactions and the spend transactions far exceeded the number of mint transactions.
Upon further investigation, the dev team discovered that at block 11002, the serial number for the spend transaction had been reused which meant that someone was exploiting a single proof to generate multiple spends. If the code was working correctly, the duplicate serial numbers should have been rejected.
"

in which they said clearly the hacker forging issue can be found by some method, even though possibly the free chainz explorer could be wrong, there do be some method to check it out. but unfortunately the devs did nothing.
