Or another option - there is something seriously wrong with cryptcoin protocol and/or blockchain (because it adds 10 CRYPT to one address but it doesn't subtract 10 CRYPT from the address from where it was (supposedly) sent).
The exchanges would have picked up on this instantly, so that isn't the answer.
Exchanges don't care or check from which addresses the coins come. They are only interested in that they get coins on the address that they control (they have private key).
I guess that there was human error (or multiple errors). You can't expect that the existing wallet will create "anonymous" transactions if this functionality hasn't been finished yet (and of course it cannot even theoretically be compiled in the executable file of the current wallet).
The exchanges do care very much, they check the addresses vs confirmations all the time for double spends
That's how WC was caught out.
I don't know what WC is and what technology it uses.
How can you check "addresses vs confirmations"? Confirmation is a number associated with one transaction. Address doesn't have any such number. Exchanges track confirmations.
It is not the job of an exchange to prevent double spends. They can't prevent or resolve any double spends at all. The network itself (protocol and/or blockchain and/or miners) needs to "resolve" double spends.
If CryptoNick's example is valid, then this actually means that CryptCoin network may actually allow double spends (but I seriously doubt this).
First CryptoNick spent 10 CRYPT for donation, but this probably didn't decrease amount of coins on his address (maybe it decreased number of coins on another address, but we don't know that). So that means that these 10 CRYPT coins may be sent second time to another addess. Voila - double spend.
Nope no double spend! I verified that there are ways to do this and you would need to program it which is what is going to happen, I am sure this is what they are working on since it is so simple. I expect there to be a new tab in commander with this functionality embedded into it. Such a simple idea! You only see positives correct but I could make it look like zero if I wanted. The blockchain is fully in tact too all of the transaction info is there on the block. I am amazed it was this easy!
I don't know if Crypt Dev's would want me to divulge their plans. That is my $10 donation which is truly not showing my total amount of coin. Not a joke, not trying to be funny here at all. They will implement 2FA and all kinds of good stuff since this is why they created Commander. Makes so much sense now and with an SSL Commander is locked down.
