So my 30Mh farm has been "Payment received - waiting 1 confirmation" for over 8 hours. Anybody else have this kind of problem? It was a 6-hour rental, it should have been finished by now but instead it hasn't even started.
ANNOUNCESome of you read probably the announcment by mtgox that triggered a brief BTC selllof:
https://www.mtgox.com/press_release_20140210.htmlIf you read the technical details, then you'll see that there is a kind of attack that allows an attacker to alter a hash of an existing transaction that is just being propagated on the network.
So the attack goes: 1/ Attacker request withdrawal from Exchange; 2/ Exchange send, and store Transaction TX on database; 3/ Attacker alter the TX number of the transaction 4/ Attacker claims to Exchange it never received funds 5/ Exchange check Transaction TX Id on database and indeed sees it does not exists, send again.
That being said, yesterday I was puzzled because I saw 1 incoming payment for a rig, which was seen on the network (so it went to the status "Payment received -- Waiting 1 confirm", but then the transaction has now disappeared! Or rather, in fact, it appeared with another transaction number! So yesterday I was puzzled and suspected maybe a double spend.
Then today, I got 6 more of those. Each from differents users.
Now I know where this come from. The sender are of course not attackers (wouldn't work in above describded attack) but probably side effect in an ongoing large scale attack -- but this is only some guessing from my side from the little I know now.
That being said, if your rented rig is in status "Payment received - waiting 1 confirmation" , then you are probably part of the 7 transactions that dissapeared, and I'll deal with you individually in the next 3 hours -- read, checking real payment and unblocking.
