Is Blockchain.info using this crc16 method or otherwise vulnerable to this?
 - http://bitcointalk.org/index.php?topic=85648.msg943612#msg943612

Honestly I'm not sure. The standard Yubico SDK is used and both the public and secret key part is checked. There has not been any security updates to the SDK recently so I assume it is ok.

 
how many blocks does this: http://blockchain.info/q/hashrate   look back?  might be interesting to give the look back as a parameter.   

does it go across retargets?

It uses the 24 hour avg difficulty (~140 blocks) and it know consider re-targets.

Quote
public double getNetworkHashRate() {
   return (getDifficulty() * (4294967296L / (((double)1440 / (double)getnBlocksMined()) * (double)60))) / 1000 / 1000 / 1000;
}

thanks.

should you ever get bored a good difficulty estimate would be nice  Wink

Meh. I got all excited when I saw the cydia update for the blockchain app. Turns out its  an unrelated bug fix and still broken on 5.1.1.

Another donation awaits you when the 5.1.1 fix is released Smiley.

account was locked for whatever reason (probably because my mail provider hiccuped the last couple of days and i entered the wrong email codes and/or my browser completes the wallet adress which is counted as a login try).

please unlock!

Issue with the new jailbreak should now be fixed. Turned out I needed to code sign the app with a self signed certificate rather than no certificate at all. Any donations appreciated.

please unlock!

Done

Just jailbroke my iPod 4G and it keeps rejecting my password, I even copy-pasted so I *KNOW* it was correct.

I have suspicions that it is because the camera on the iPod sucks and is mis-reading the QR code, but that is just a guess.

What can I do?

I don't understand what you could have copy-pasted.  You open the app, click "Pair Device" and then scan a QR code.  Theres no pasting to do.

QR codes have an incredible amount of redundancy in them and I would be very surprised if your camera was mis-reading it.

Sorry... I copy and pasted my decryption password, which is quite complex, to ensure that I was not mistyping it on the iOS keyboard.  I also attemtped to enter it on a bluetooth keyboard.

Thank you for the donations everyone.

Did you get it working in the end? Maybe try an alphanumeric password only if possible.

Feedback needed on the interface: compact or original as default?

I am always a little confused about My Transactions page.

I prefer the compact version but:

maybe I'd like to see MY addresses that took part of the transaction (From/To) and not third party addresses.


btw, great work, as always!


edit: another idea

at detailed view, when I receive funds, I'd like to see my address at the LEFT column. You can change the direction of the green arrow (to the left), it's good for the color-blinded people too (red-arrow to the right = paying / green arrow to the left = receiving).

That way all of yours addresses belongs to left column and all the third parties addresses (and change addresses) belongs to the right column.


You guys have really come up with somethin'

I never did get it working with my main wallet (maybe because of 2-factor auth?).  But on retrospect I thought maybe that isn't a bad thing and setup a new 'mobile' wallet.

BTW: Where can we change the default miners fee?  I have looked and looked but can not see it, I am starting to feel very dumb :/

I just installed the javascript verifier extension for chrome and when I went to the my wallet page and clicked the "turn off" button at the top right for logging out before I entered my pw and opened my wallet it sets off the javascript verifier and gives me the following two boxes:



If I just open the page https://blockchain.info/wallet/ and log in I don't get any messages..

Did you try clicking that button a few times in a row? Sometimes, for what ever reason, it takes a few clicks.

Critique: Most of the buttons that are clickable in the javascript use an I-beam on mouseover, instead of a hand as would be expected.

I'm having a few problems with the website (tried on both Opera and Chromium):

1.  I can't import private keys generated with vanitygen. I've done it once successfully, but on a new account, I can't. I've tried two different ones. They have the format 5xxxxxxxxxxxxetc.

2.  Once an address is added, it can't be deleted, nor can the existing wallet-generated address be deleted from the archive. It says "You must leave at least one active address" even though there is already an active address. Even a "watched" address can't be deleted.

Aren't 5xxx addresses test net?  Either way I thought only 1xxxx addresses were valid?

That's a private address.
