Ongoing Bitcoin Malleability Attack you can read more about it here : http://blog.coinkite.com/post/130318407326/ongoing-bitcoin-malleability-attack-low-s-high

thanks... so sir do you know if i can still recieve my bitcoin on it or not?
how can i retrieve it?

There's a explanation on the link aswell about that.
Nothing changes, the receipt will recieve your money, the thing is, your sender TxID isn't enough to know if your receipt received the money, since they are playing around with the "S" value once your transaction becomes public.

Blockchain.info wallet seems most affected. Try using other block explorer like blockr.io

Over there you will see your transaction and tx id. There is nothing you can do. You have to wait until your transaction isn't confirmed. If this doesn't happen for a while than you can do manipulation in your wallet to get your coins back and try sending them again (I don't think you can do this with blockchain wallet, I think you need to contact their support or they will eventually introduce a fix I guess).

Effectively you will create a double spend and then wait to see which out of two transactions will be confirmed first.

playing on a casino today after i deposit and lost my transaction appeared again waited 30 mins and still pending.

Same here, got 2-3 transactions blocked. Hope it solves soon, this is not very good for Bitcoin.

This will disrupt the development of bitcoin in the eyes of the market. such a problem will be fixed soon. hopefully

it's good that there isn't fully adoption yet, because problem like those would kill bitcoin in these situations

it's better to leave the beta stage before embracing the world

I sent myself coin from Armory to mycelium about an hour ago. Still no confirmations, is there anyway I can get the transaction to reject so I can free up these coins?

Yeah this happen to me when I'm betting on luckybit  :-\

Another Q , why this address show minus amount ? Why this can happen ? What does it means ?

I am too facing one very rare problem with blockchain.
When i try to send money it says "Transaction Submited" but after some time money comes back in my wallet and i get a email that blockchain transaction failed because of less fees even though i am sure i pay 0.0001 btc every time which is required by blockchain network..This problem has happened twice with me!!!

It means that bc.i is flawed the balance is 125.00000036[1].

I agree. Small attacks would in the eyes of the public make Bitcoin look insecure and the price would probably drop. From what I have seen so far there has been no significant price drop and so far everything is working fine.

woah.. this is the first time i saw a negative sign
on a final balance. what happen now to your wallet?
do you guys think changing wallet will help some of
our problems for this? hope this will be fixed soon.
me also send 4 btc for withdrawal the other day.
but still until today. i didnt recieve it.
it says unconfirm .. i do not know how to get back.
pls help me guys. what should i do?

From the looks of it most wallets are affected. Local wallets are easier to repair though as you dont need to contact someone from support and wait till they get it done for you. You can just fix it yourself. E.g. in multibitHD its as easy as clicking a button.


From what I read there is no easy fix, wallets need to be able to handle this.


Show us a transaction ID.

its all good now. i saw my 4 btc to my other wallet.
but it really takes a long time.
and theres another 4 btc appearing unconfirmed that i didnt send to my self.
i dont know where it comes from.
but when i see it in blockchain.
it says transaction cannot be found.
