00:05 < Herodes> imperi: make sure not to leave the house. U never know what might
                 happen. Shocked
00:05 < Herodes> \o/
00:05 < MagicalTux> some people have bogus balances
00:06 < Herodes> what do you mean by bogus balances?
00:06 < MagicalTux> some of the really old accounts have a corrupted history, causing the
                    balance to be wrong


00:08 < MagicalTux> I fixed the trade entries so now when you buy 1 BTC it shows you
                    bought 1 BTC
00:08 < go1dfish> MagicalTux: if you stored a running balance separately...
00:08 < x6763> MagicalTux: nice, i like that!
00:08 < go1dfish> and that was used to determine if someone had enough to make a trade...
00:08 < go1dfish> and someone inflated their balance...
00:08 -!- Vandroiy is now known as VandroiyOtherPC
00:09 < go1dfish> rerunning the transaction log and getting negative balances is exactly
                  what would happen I think
00:09 < MagicalTux> go1dfish: some of those accounts are really old, so I wonder
00:09 < MagicalTux> I'll be comparing old & new balances~


The plot thickens... he went on to say that they are usually negatively bogus. Anyways I guess this is what's making it so difficult for them to verify accounts.

Once a transaction has 6 confirmations, it is extremely unlikely that an attacker without at least 50% of the network's computation power would be able to reverse it.

If you were there, did you ask how many days they have known this?

No, didn't ask that, I was mostly there to ask questions about my account.

Obviously they're not up on sophisticated modern transaction processing techniques. If only they had read the 1458 edition of Della mercatura e del mercante perfetto by Benedikt Kotruljević.

It's got to be only since the rollback was complete and they started processing account claims. I've got a log from the past several hours if anyone wants it.

Also, this was just asked:

"<MagicalTux> [13:18:59] <Ooofo> MagicalTux, on these corrupt histories, do you at least know what the balances are supposed to be? <- yes"

So he knows what the balances are, it's just sounds like accounts with really old early transactions don't add up to the balances. Thus he needs to process them differently or manually correct them, I assume.

Phew. That's quite a bit less disparaging than the thought that people could lose money because of corrupted histories.

I was about to post something to the same effect. It seems like they have it sorted out but it's just making the process take longer.
