Does anyone know if this is the same format as Electrum? I am away from my laptop or I would check.

I don't think so, Electrum has a more sophisticated deterministic algorithm.

Do you have any plans to implement this? If not what would you consider a decent bounty? I see two very useful use cases for this:

1. Import the master public key for watch only balance/notifications. I *love* the MyWallet service and the iPhone app. Being able to see my balance or if a payment has been confirmed / received is awesome. However this breaks when using Electrum because of the way it handles payments and change addresses. See http://acceptbit.com/

2. Actually importing the wallet seed (hex or mnemonic) and using MyWallet as a backup/clone/whatever. If you go this route please make sure that you don't limit yourself to the seed size that Electrum gives you, it actually supports much bigger seeds (I have successfully feed it a 512 bit seed and it worked).

Blockchain can not do full OTP validation on Mt.Gox Yubikeys and and only uses the 16 byte prefix. It's not ideal (Related: https://bitcointalksearch.org/topic/how-can-blockchaininfo-use-the-mtgox-yubikey-64300).

Damn. I was hoping that it would be an actual OTP, instead of something that is vulnerable to a replay attack.

@piuk: what happens after 5 wrong login attempts?

Your account gets locked for 4 hours preventing further login attempts and you will get notified by email.

Note the minor typo on the new Brain Wallet feature.

Thanks

I just got a Yubikey from Mt. Gox. When I go to my blockchain.info security details, I see that I can choose "Mt. Gox Yubikey." Mt. Gox claims that their site is the only one where this Yubikey will work. Did piuk hack the Gox yubikeys so I can use the same yubikey here and at Gox as well? It seems that way from the site, but I'm afraid of going through with it in case I lose access to my coins. Is it really that simple?

The Mt.Gox option only uses the 1st part that is always the same, not the one time password. It just adds a little more entropy to your password. If someone knows one of your yubikey passwords from the past they can use it to login with out needing your yubikey.

Note the minor typo on the new Brain Wallet feature.

"A Brain Wallet if a private key..." => "A Brain Wallet is a private key..."

Awesome new feature and glad it is compatible with bitaddress.org too.

No, they are encrypted, so password is needed for import.

Thanks - I thought (and hoped!) as much.

Newbie question:

Regarding the wallet backups that I receive via e-mail - if someone had access to them would they have access to my coins? Or would they still need my password?

List of all bitcoin nodes blockchain has connected to: http://blockchain.info/ip-log

You can search for an ISP e.g. http://blockchain.info/ip-log?search_input=verizon

Wow... Looks like there are way more people from my hometown than I would have thought.

Anyone from Casper,WY PM or respond here.

* You can now import the output form vanitygen.
* Brain Wallet import now supported (Same format as bitaddress.org)

* When sending a transaction the UI will no longer ask for a private key for a watch only address unless there isn't sufficient funds available in addresses which already have a PK associated.
* Fixed DNS SPF records (Thanks Stephen)
* Potential security issue with uservoice script. Uservoice will now only load on https://blockchain.info/wallet/support-pages. (Thanks coderrr)

The pool 50BTC.com still does not appear on this page http://blockchain.info/pools

Finally got around to adding your ips. Sorry for the delay.

One third of the BTC came through immediately, and no more has been transferred in the last two hours. I'll just wait it out until tomorrow and see... Huh

Payments > 1000 BTC can take few hours depending on how busy the service is that day. Sorry for the delay.

wouldnt it be awesome to just import a wallet.dat?

Yeah I really wanted to do this but with pure javascript I don't think it's possible. The alternative option is introducing a java applet but it opens up a lot of potential security issues (Same with a downloadable java app).

The JSON RPC import can provide similar functionality though.

Currently not letting me send funds. It says 'sending transaction' beside 'Status: Subscribed To Wallet', but then nothing leaves my wallet.

Edit: I think I see what's happening. I am waiting for the change of an unconfirmed transaction.

Maybe a HappyHour every day could help the problem?

Do you mean a time where the bonus is paid? I think paying exactly when the funds are needed and charging when they are not is the best way and is what Piuk had in mind. I'm assuming he's tweaking or studying exactly how to do this and will bring that back when it is ready.

Is the mixer out of bitcoins? I received a large txn anonymously. One third of the BTC came through immediately, and no more has been transferred in the last two hours. I'll just wait it out until tomorrow and see... Huh

It doesn't seem to offer the bonus anymore or I'd shoot some in.

I was able to send some funds today, but another transfer I make fails all the time with this error:

Application Cache Error event: Manifest fetch failed (404) https://blockchain.info/wallet/wallet.404.manifest

I tried refreshing, of course. Also tried opening in a fresh incognito tab without any plugins. No go.

The URL above really returns 404.

Can you explain what's this file, is it supposed to return 404, and how do I proceed in sending funds?
