Alert: chain fork caused by pre-0.8 clients dealing badly with large blocks

[nelisky]

Coins are safe, but the current value in them is not. This will have consequences.

Right now I don't understand how can coins be safe if transaction was made on the 0.8 blockchain? I'm hoping for a detailed official answer from the devs.

Coins are safe because your transactions will exist in the 0.7 blockchain too. Only issue is double spending and that's why you should not buy any coins from anyone right now.

is it safe to redeem private keys on gox?

[instaBoost]

I smell a mass sell off along the horizon...

[adamstgBit]

what will happen to the resent tx's?

Revert to 0.7 and all ok

sorry can you elaborate on this? reverting to 0.7 means the qt client has to be 0.7? I just upgraded to 0.8..

is that what you mean by it?

Only miners need to do so. General users need not to panic.

I figure both clients would send the same information along about a transaction whether 0.7 or 0.8 so how could a fork be made in the first place?

Or is the program just "confused" about handling larger blocks and things are fine?

[WikileaksDude]

If you are mining on bitcoin version 0.8, please stop for a few hours.

my rigs are mining on cgminer 2.10.5 so I'm confused as if I'm mining on .5 or .8

Check with your pool. If you don't know, just don't mine for a couple hours.

Someone save the deprecated chain...just in case.

are my coins that I transferred to a different wallet yesterday safe or not???

I don't see how this can be handled without any coin loss, what about all those block rewards that were mined after the fork? how can they be re-distributed to the rightful owners?

Oh Oooo

Yes, they're safe. (You should make sure to keep the old wallet just in case, but since your transactions were done yesterday and presumably many people will re-run all lost transactions, it shouldn't matter.)

1) If you run a mining pool or are mining solo, and have upgraded to 0.8, downgrade to 0.7

2) If you are a normal user, do not perform any important Bitcoin transactions until you get the all clear.

3) If you are a pool miner and you know your pool has not downgraded, stop mining.

4) If you performed any transactions recently, be warned that you cannot rely on them.

This is going to be on every nerd news website in 24 hours. What a black eye. A few people can stop bitcoin from functioning properly and not even mean to do it.

No, no, it's like the NASA adventures... we aaaaalmost lost contact with our Mars Rover, but then after hard work from our engineers, we finally made contact with it again, it's all fine and dandy now! Everybody cheers at the great NASA bitcoin engineers, and life goes on.

You are not solo mining, so it depends on which bitcoin version your pool is running.

[Herodes]

is it safe to redeem private keys on gox?

GoxUSD, GoxBTC and any other Gox-currency is safe, BTC traded on Gox is not on the block-chain, only in Gox database, it's virtual BTC so to speak. The only time Gox touches the block chain is for deposits and withdrawals.

So - yes it is safe.

Looking forward to Gavin's "I told you so" message being posted soon.

I was building on my previous post stating "if they have more than 11 confirmations as of block 225446". But you are right that it was misleading, just trying to write as fast as one can.

PANIC SELL!!

Price has just dropped to $30...

Im buying at $29  

On which exchange?

[MysteryMiner]

Just my 0.5 bitcents to calm down the panic - Bitcoin protocol was not compromised, regular users should not change Bitcoin software version right now, only miners should change back to 0.7.

Now sell all your coins so I can buy them for cheap!
