Mark Karpeles just posted on GitHub at approximately midnight EST. Here’s the full quote:
Just to update this thread, it seems that this discussion is mostly stale now. We (at MtGox) will implement this new hash index in our transactions database and start working with it (we will announce a maintenance as we will have to stop bitcoin deposits too during the database schema update) and will start providing this new hash when customers are withdrawing bitcoins, litecoins, or any other coin based on Bitcoin we may support in the future.
We will also provide an API that will allow our customers to use this hash to retrieve the transaction hash as seen in the blockchain once the transaction is confirmed, and will hope others (blockchain.info?) will index this value one day.
We also invite other exchanges and businesses which may need to keep track of bitcoins they send to use this same method, since dealing with multiple variations of the same thing wouldn’t be very productive.
If nobody does it, we will also post some test vectors for regular (in=>out) transactions in the near future.
What Mr. Karpeles is saying here is quite clear. They have found a solution, and will be implementing it and testing it very soon. I hope they keep us up-to-date as this progresses. If this is the start of improvements to MtGox, I’ll be very excited. I expect to be disappointed–it is MtGox–but a little bit of good news could do his company a whole lot of good. If MtGox is not insolvent, which, while possible, doesn’t seem likely, then it’s likely more profitable for him to fix the issues than to try and cut and run. If Mr. Karpeles’ return to his company means this will happen, I’m truly happy.
I’m eager for the prospect of a fixed MtGox–a truly fixed one. If he can fix up their code, repair their various damaged ties, and continue on, we (and the world perception of Bitcoin) would be better for it. A reborn MtGox is the ideal, not a failed MtGox.
Perhaps this is simply the return of the king?
Really big news! I imagine the price on MtGox is going to shoot back up quite a bit.
