I have been following the coin tumbler wallet activity since, I was sending some coins through it when it stopped on the 14th. Actually, I am concerned as this was a pretty good size load for me, more than the current balance on the account (I know, it could be at other addresses in the same wallet from change etc)

Anyway, there was a lot of movement yesterday and I started to ask... am I screwed? SO I started looking back, based on what I know about it, to see if it looked like I could identify whether it was processing orders more recent than mine... what I saw worries me...and I am hoping that someone here can explain it.

That is the account in question, Scroll down to the end of 3/14 where the next pile of transactions is on 3/19

Now this is where things get strange and thousands of coins start moving but... many of the transactions are from the main address back to itself. Now, this makes sense to me for consolidation purposes, since all transactions refer to previous ones... so consolidation into big ones before dispersement makes sense but.... shouldn't this be a zero sum game?

Look here: http://blockexplorer.com/tx/cff8306919dc875fa2c31589980e7a39c2023e30ffdd174dbd123afe5761293b#o0

Ok so a lot of inputs from the main address, and one output to the same, both input and output the same...good. Then find the same transaction back on the ledger for this account
 balance from previous trans: 1391.59
 balance from this transaction: 1721.42

That doesn't seem like it can be right, is this just a blockexplorer bug? Seems like it must be but... I am definitely concerned with all this action in the account and not seeing any of my several hundred coins. I have moved coins through it with no trouble before.

It's caused by the way BBE displays balances. I have to either calculate credits first or debits first, and calculating debits first results in negative balances, so I chose to do credits first. This results in a very rare situation with sends to self where the balance temporarily appears to be more than it actually is. Notice that the balance corrects itself when the sends in that same transaction are taken into account later.

I'll eventually do something to make this more clear, but it's a low priority.

That site will generate a valid address from any hash which is probably what whoever sent those coins used.  I highly doubt they actually own that address, but it is possible.

Yeah, it's a valid address with an all-zero hash. A few cents were sent to it, but they will almost certainly never be spent.

Its just highly improbable that anyone has the private key. It is entirely possible (if unlikely) that someone generated an address, sent some coins to it, and it happened to hash to 0.

It would be impossible to prove this for the same reason as its impossible to prove a lost wallet. However, it would be possible to prove that someone has the private key...if these ever get moved.

That said its also impossible to prove that said private key existed before the coins were sent there...since collisions, while unlikely, are possible.

Though, thats absolute proof.... I would say you can be pretty darned sure to the tune of many 9s that this is the case.

Due to my calculation there are 844.27 BCs in CoinTumbler in the addresses

If you have the addresses where you sent the coins, you could also follow them and see if they were transfered to the second address or if they are still somewhere else.

My wallet is in sync, but still missing 1 transaction. They are in the blockchain, and even the balance that the blockchain shows, is correct but they are still not in my wallet on my mac. To solve this , i first reloaded the blockchain but with no results, than I have made a backup of the wallet, export the wallet, made a copy of the wallet.dat file, before deleted my wallet, installed a new one, imported the old wallet.dat file, sync again but still the missing the transaction.
Opened my console, used the command "dumpprivkey", but got the error 05 "invalid 42 address" Tried to "validateaddress" but not possible because of "invalid address", create a new address but same results.
What is going on with the wallet?
