IP blocking?? What is this?

it's under security options, you can lock the IP addresses that are allowed to connect to your wallet.  This historically has never affected the android app, but it appears to do so now.

my android app now doesn't work and triggers blocking because of my IP locking, it didn't do this before...
Will

I've had a couple other users note this change in the last week or so. I already sent this off to Piuk, but thanks for the heads up!

Minor feature request: Please print out a text version of the TOTP secret key below the qr code image on the two factor authentication settings page.

I'll pass this suggestion along, but in the meantime you can use a different QR scanner app to get a copy of the secret key. If you ever need to reset two factor authentication, then you can just submit a 2FA reset request. We usually process these within 12-24 hours max (I check them multiple times a day).

Any chance you could add a $ approximation to the miner's fee on the custom send money page.
It's a little inconvenient to do have to calculate the rough value of what I'm willing to pay and then double check I've counted the zeros correctly.
It's very easy to accidentally pay 10x more than was intended.
Thanks.

Not 100% sure, but with the new chrome app, the inactivity timeout loggout doesn't seem to work.

I have it set to default 10 minutes and it never logs me off, whereas before I had to relogin all the time.

What happened with Firefox browser extension?

https://addons.mozilla.org/en-US/firefox/addon/my-wallet/  gives me "We're sorry, but we can't find what you're looking for."

Also, many users (including myself) have reported that version 1.98 wasn't working properly, did anyone from support comment about that? I can't find any comment regarding this.

The mining profit and electricity consumption stats are said to be based on electricity consumption of 600 w/gigahash. This is out of date by factor of at least  100 . Can you update? (Block Erupters are about 7.5 w/ghs and some of the newer ASICS are under a watt). Otherwise the false impression is being given that the network is hugely inefficient in terms of electricity consumption, which is unfortunate.

Please enable HSTS to avoid sslstrip or a MITM replacing the http page.

Added.

Thanks for adding, it was working fine but it seems that there is not working right now.

Inspecting with http://web-sniffer.net/ you can see that no "strict-transport-security:" is set when you type https://blockchain.info.

I'm checking into why this isn't on the Firefox app page. If what you are reporting about 1.98 was widespread, then it may have been removed until this can be resolved.

Annoying niggle in the Android app - clicking the transaction has in the transaction popup sends you to an address with https:/ instead of https:// - which for me defaults to a Google search instead.

I'm not able to replicate this, what version of the app are you using?


App manager says 3.6 - Play Store website says that's the latest version too. Here's how I get to it: Open app, choose a transaction to open "Transaction Summary" popup, press the underlined Hash value to open the link. I'm opening the link in the default Internet app (Android 4.1.2) which throws me to Google as the URL isn't recognised. Maybe other apps auto-convert https:/ into https:// ?

Lastly, I used to be able to add a label to an address by choosing the transaction - is this still possible? I get the impression the "add note" button adds a public note instead?

It adds a private note to the transaction (stored client side). The only way to add an address label at the moment is to copy the address to clipboard, open the address book, swipe to "sending addresses" and choose "paste sending address". The other way was much easier, I'll look at adding it back in.

Great - good to know there's a workaround in the meantime. Cheers.

Yes, please print a text version of the key, it would be very convenient for users with older phones for which there are alternative Gauth implementations but none of them can scan QR codes. Other QR scanning apps are also problematic to work with.

Yeah it definitely doesn't log off after inactivity.
Also, after typing in the secondary password to make a transaction, it will never prompt again till next session.
Because of these two factors, a user's chrome app wallet left minimized and computer left unattended, all coins can be subject to theft.

IMO, the secondary password should function like a PIN, and needs to be entered for each transaction.   The secondary password should only expose the private keys to the system just for signing the transaction.

I've been using this site for about a year.
Works great  when you don't want to set up a client (and download the whole chain Wink).

Feature suggestion - using compressed public keys by default

As far as I was able to check, the blockchain wallet uses uncompressed public keys by default. Since it is very popular, a lot of people are using uncompressed keys. If you were to switch over to compressed public keys, each transaction sent from the wallets using those keys would be smaller, meaning the future blocks could accommodate more transactions. Just a way to be forward thinking and "greener" Wink.

More info on compressed public key - http://bitcoin.stackexchange.com/questions/3059/what-is-a-compressed-bitcoin-key .

Feature suggestion: When creating a payment request (by clicking the "Request Payment" button on an address page) it would be great if one could enter a EUR or USD amount. Right now you can only enter BTC amounts, but I do know several merchants who price their products in Euro and would like to be able to create payment requestsbased on Euro amounts.

This!

You could even get fancy and give us the option to pick our exchange (for price) and give the option to enter a % premium or % discount.

I totally agree they should do compressed keys, but for those of you that want to use them now, you can import private keys made from other clients, so you can make a compressed key with another client then import it into blockchain.info. And no I'm not saying they shouldn't add the ability to create them, but you can technically do it now with some hassle.

You can tell if a key is compressed if it starts with an L or a K. Uncompressed keys start with a 5.

This should be fixed now.

Any chance you could add a $ approximation to the miner's fee on the custom send money page.

This will be available next update. Btw you should get a warning if trying to send with a fee above 1 BTC, perhaps the warning should be lowered to 0.1 BTC.

Not 100% sure, but with the new chrome app, the inactivity timeout logout doesn't seem to work.

Will be fixed next update as well.

What happened with Firefox browser extension?

I'm having trouble getting it re-approved into the extension store. For now it can be downloaded directly from here https://github.com/blockchain/My-Wallet-Firefox-Extension/raw/master/blockchain.xpi.

The mining profit and electricity consumption stats are said to be based on electricity consumption of 600 w/gigahash. This is out of date by factor of at least  100 . Can you update? (Block Erupters are about 7.5 w/ghs and some of the newer ASICS are under a watt). Otherwise the false impression is being given that the network is hugely inefficient in terms of electricity consumption, which is unfortunate.

The electricity cost on the existing chart could either be changed a certain date when the first ASICs became available (1st Feb 2013?) or a new chart started for only ASICs . Not sure which would be better.

Inspecting with http://web-sniffer.net/ you can see that no "strict-transport-security:" is set when you type https://blockchain.info.

It is only set on wallet pages e.g. https://blockchain.info/wallet

Feature suggestion - using compressed public keys by default

The out of date iPhone app doesn't support compressed public keys which is preventing them from being made default. When the app is finally updated  this can change.
