What is strange here? This Is probably inside job, small bug to be discovered by some stranger and exploited in this way, this is only dream of every hackers, and those who created this code didn't notice this at debug ..? I really want to be believe.

The real big mindfuck is the following one: Since this coin depends on you haven trusted that the developers destroyed the masterkey files (which would give access to the total supply in a total impossible to prove way) some dev could have the key and could access the supply, fuck shit up, then claim its a bug... nobody would know.

The whole concept of this coin seemed so stupid to me since the beginning.

how can this be possible? isn't zcoin like all the other coin completely and fully open source? if someone want can expect the code and check exploit/bug/whatever, on a side note, this bug explain why the price tanked by 25% in few days

This is something that ends up killing the coin, we saw the same happen with DAO and now with Zerocoin. This is what differentiates a good project from a bad one, I feel sorry for those who invested and end up losing money on this one.

The DAO had peoples coins actually stolen from them. This is completely different. For the timeframe that extra ZCoins were being dumped the price was actually going up and it only went down after this became known, and even at that it got fixed in a fair amount of time.

Nobody who bough these extra coins are losing anything

Best solution for this, is that this teach, if really working and this code can be fixed, is to be reused in another project. This coin is finished. This team is not to be trusted anymore. Bagholders will try to recover but only to find good exit point. Sad but true!

Summary:
The fix posted (so far) to Github is insufficient
- does not stop the attacker from continuing to create fake Zcoin Spend transactions
- prevents regular users who are holding private funds from moving them to a public address
- does not explain fix the issue of fraudulent Zcoin Spend transactions passing validation checks

Woke up to this article today : https://zcoin.io/language/en/important-announcement-zerocoin-implementation-bug/

One more reason for me to stay away.Today's it's a small bug,tomorrow could be my wallet.Attackers gained access anyway.Wake up!

I agree with you. this event involves a question of trust, at least, i can't believe it again

Trust the math and no one else. It is so simple. There are and will be new experiments. It is totally normal and only way to progress. But there need to be some basic minimum requirements.

Maybe warnings were off during the compilation and that case didn't appear in "probable bugs" section?
