Hai guys, bad news unfortunately.

You might have heard that some pools running yiimp got hacked in the few last days.

Well two days ago, the same hacker that hacked other pools, hacked my pool. He stole some DAS, some of it my mining fees, some of which should have been paid out to miners, but was not due to some blocks being marked as orphaned when the new wallet update came out, but apparently later was included in the chain again - not sure if this was a chain reorg or what happened, but apparently it is a situation yiimp is not equipped to handle, since they still showed up as orphans.

A payment was made for some blocks that was not marked orphans, and after hexpool sent me the fix for the coin daemon, a single block was mined, but I then disabled DAS mining on the pool, figuring that I should wait for an official update from the dev. After disabling, I did not look any more into it, figuring the funds had been lost due to the blocks being orphans..

Anyway, bottom line, the hacker stole some DAS belonging to whoever helped mine those "orphaned" blocks last week. Right now, I do not see how I can pay back the miners, partly because the DAS is stolen and not in my control anymore, partly because yiimp deletes information about shares after a payment is made..

I will contact nova exchange and ask if they control the address the DAS was transfered to, if they do, maybe they can give some kind of information on the user account associated with it.

Will let you know if this leads anywhere.

I am very sorry about this happening and I do apologize a thousand times for the lost funds.

if it was because of the reorg, then just resend the transaction ids to the blockchains from the wallet and it will re-update the status of the "orphaned" blocks
