This is intentional (or at least cannot be change now). It should be fairly easy to reverse the byte order.


The USD ticker was switched to bitstamp. The spread between Mt.gox and other exchanges is getting a bit ridiculous and I don't beleive it to be a fair representation of the current market price. The charts (http://blockchain.info/charts/market-price) will still use Mt.gox for consistency.

Submitted a Blockchain Desktop App to the Mac App Store today. I'm not sure if anyone has tried to get approval for a bitcoin client into the mac app store yet but hopefully it might get approved. If not it will be distributed by direct download.

This error should be fixed now.

What browser are you using? The identifier may be stored in your browsers localstorage, which often persists after the cache is cleared.

Otherwise please PM all the info you have (IP address, time the wallet was created etc).

The old bitcoin address has been moved into Archived addresses so you will be able to receive funds to it, it is just hidden from the main view. If you could unarchive that address temporally and test sending from that address using the android app that would be great.

The fixed was actually included in v3.54 release today. Did you update today as well? Would it be possible you could test your old address (the one known to cause issues) with the latest app. If you post it I will send some bitcents to it.

Password guesses are not limited so this sounds like a problem with 2 factor authentication to me. Do you have two factor authentication enabled? If so please use the form at https://blockchain.info/wallet/reset-two-factor in order to have it removed after which you will be able to login using only the password.

Please can anyone experiencing the "Error Response Invalid signature" error please update to the latest version (3.54) and report back if the problem is fixed.

If the problem is not fixed, an alternate work around is to login through the web interface.

Please see this announcement on the issue http://bitcoin.org/en/alert/2013-08-11-android

An update was made to the blockchain.info app yesterday (v 3.52) to fix the problem for newly generated private keys. If you are a user of the blockchain.info android app you can either login through the web interface and send any coins to a new address or update to the latest android app and send all coins to a newly generated address. Alternately please wait for another update will be issued shortly to automatically rekey all android wallets however more testing is needed.

Yeah that makes sense. I've just left the donation addresses for wikileaks and erowid so if someone does accidentally an address at least the coins go to a good cause.

I'm not sure, which link is that?


From the addresses in your PM it seems like the coins arrived at the destination address a while ago. If they are not showing please make sure your client is up to date or if there is an issue with the receiving website.


So this is your bitcoin address http://blockchain.info/address/1Ns9v93ngjYJavLc6VMQj7HKPCv5BCPSRE? and you are currently mining coins? No transactions from that address appear to have originated from blockchain.info.

http://blockchain.info/tx/cddf4fa049c7b57a3065c8dc31ddf2c52c03fd4ea98e18895d72bfdbb9c56dd5 is your transaction but you do not recognise one of the output addresses? If you have imported the wallet from Bitcoind then it is likely a change address.


Yes someone has setup a bot to automatically sweep coins sent to the demo wallet. It doesn't really matter if I change the addresses nobody should send funds to any addresses in the demo wallet as anyone can spend them. I will add a warning popup if someone tries to copy and paste an address from the demo wallet.

I take responsibility to fix any bugs as soon as possible. However it is impossible to tell whether the private key was actually lost or even in the wallet in the first place so we do not offer any refunds (The exception being issues shared send which is server side). If it was indeed an issue with the app then I do apologise but any coins hosted with blockchain are your own and you should always keep your own backups etc. The new version of the app allows you make backups to external storage much easier.


They should PM me.

2weix's coins were lost because of an issue with the first version of the android app. He generated a new address and it didn't properly sync with the server. Unfortunately with the phone being rooted and accessing the local wallet stored on the app the coins are permanently lost. The the bug was fixed a while ago in the new version of the app (https://play.google.com/store/apps/details?id=piuk.blockchain.android).

As far as i'm aware there is no issue with shared send at the moment. I'm trying to resolving outstanding problems now. Please do not reuse shared send addresses they are removed after the first transaction so subsequent transactions may not be forwarded immediately.

Did you record the wallet recovery mnemonic or make a paper wallet?

If only. That figure includes none-shared transactions as well and the majority of blockchain's transactions are free.

Luckily the site has very low operating costs.

I've had at least half a dozen people contact me claiming to own the blockchain.com but none have been able to provide any proof of ownership.

If he his the genuine owner I am willing to pay a premium for it.

Apologies for the downtime. Twitter https://twitter.com/blockchain is normally where updates are posted.

It is a problem with the android app. An update which fixes the problem was released yesterday.

Did you use custom send in the android app to make this transaction?

Credit vouchers are not fully tax exempt. If you are buying and re-selling VAT is still due on the profit made from resale. Exchanging BTC for sterling is more complicated because technically you are redeeming the voucher and may be liable for VAT on the full face value.

The plus side for selling coins is you don't need to register for VAT until your profit exceeds £79k, rather than revenue. Although the site is no longer selling coins Blockchain paid approximately £40k in VAT this year.

What device did you use to make this transaction? Was it the android app, did you use custom send?
