I haven't been on the forum in a while, and looked around. I apologize if this has already been answered, and if it has, please point me to the thread.

Can someone post a concise answer as to the exact problem with Mt. Gox and whether the others have the problem or not.

Please correct me. From what I can see:

1. The Bitcoin protocol has a transaction ID, which can be changed shortly after transaction initiation (but not after the transaction is confirmed?)
2. Mt. Gox used this transaction ID for their internal accounting, while others claim that they do not use it to identify transactions.
3. Mt. Gox customers would do a withdrawl, change the transaction ID, then complain to customer service that they didn't receive their coins. The Mt. Gox system was fooled because of using the transaction ID, and then customer service would send the coins again.

So:

1) This is known in the bitcoin software.
2) Proper accounting systems do not use the transaction ID to track payouts.

No known other exchanges have the problem (or if they do, they're not saying).

Please correct me and add any other pertinent information.

Thanks,

Oatmo
