...

I get it now, thank you.
How ever: Can you confirm here that there is nothing wrong with the method I am using except that it's unnecessary complex?
I mean before users that might not understand this abacadabra think BtcBalance is unsafe or whatever.

Thanks again.

It isn't insecure* and I am keeping my account.   Using a stronger hashing algorithm would simply make it more secure.  It strengthens the user's password by making it take more resources to crack.  

I can delete my posts if you wish to cleanup the thread. PM me if you want me too.

* with the caveat:
You use a secure hashing algorithm (one is fine but three won't "hurt")
You include sufficient salt (32 min but bits are cheap so go 128 bit) which is random and psuedo-unique per user.
Your user's ensure their passwords have sufficient length and complexity.

For the record it is mostly academic because there is little value in attacking the site

Here's one example where that's not true.  If I'm referring to the use case where I use this to maintain balances for payments from customer, each getting their own address (which I've labeled with their name).  If this then were to be compromised someone could go in, add a new address, update the label with a customer's name, then delete the old one.  I'ld never know and might think the customer has a higher balance than this shows.

[Of course, I'ld not use it this way myself, but it might be [mis-]used by someone in this manner.]

BTCBalance uses BlockExplorer API, and BlockExplorer is several hundred blocks behind at the moment.  Could that possibly be the reason?

Cause of a database problem on the server the lists of the last 7 accounts made are gone.
This regards account id: 185 towards 192.
Sorry for the inconvenience.

Big update coming by the way!

Will there ever be a mobile app version of BTCBalance (or mobile-enabled website)?

Specifically, what I'm looking for is an app that lets a person scan a QR code containing a Bitcoin address and then see the balance and transaction history for that address.

For a specific use case, a mobile phone (or Android tablet, more likely) is going to be made available at an event to allow people to check the balance of their bitcoin address.  Attendees with their own smartphone can use their own mobile wallet app but for those without smartphones and those who don't know (nor care) about bitcoin, the QR code on their badge will work as their wallet.  Kind of like these, for example:



 - http://www.paymyaddress.com/


The app can be pretty simple -- a text field to enter the firstbits (and a button to optionally allow a scan), and then the balance is displayed (with transaction history below, optionally).

Since it would be used by people just walking up, it shouldn't require any registration or login.  Simply scan and view.

Is there any chance a BTCBalance app or mobile-enabled page could be built to do this?

UPDATE v1.4 -> v1.5

Added
  • Charts page. You can now check how many euros or dollars your Bitcoin balance was worth in the past.
  • If your balance in euros or dollars decreases it displays how many. The fading out of the text is still a little buggy sometimes I am aware of this.
  • Instead of waiting a very long time before the page was loaded with all the data, now you can see in realtime how the data is loaded in.

Changed
  • All data is being parsed from Blockchain.info now. Wich means your data will load almost 3 times as fast
  • You can add up to 50 addreses now
  • Total EUR balance (based on intrsngEUR)
  • Some text on the About page

@ Stephen Gornick
I will come back to you very soon about that.

The chart page is developed in the Chrome browser.
Weird, can you maybe give me some more details?


Minor update
  • Since much problems are going on with Intersango these days, I have decided to stop using there API.
    The "euro balance check" now uses the Mtgox Euro market.

If I just created an account but entered an address that had previous transactions, should that appear in the chart?

If so, it isn't appearing for me.

The chart just measuers your total balance each day and connects it to the date.
So then you can check how many bitcoins you had in euros or dollars in the past.

The first donation is recceived.
Thank you!

And another donation -> http://blockchain.info/address/1GdYkpXs7NqQt4YnT52UFHU5L5ELxKmGjX
with the public note: "Thanks for the neat service"

Thanks you!

Over 400 accounts have been created now!
I am really excited about this.
Any feedback is welcome, I would like to improve the website a bit more.
Also, do you guys use the chart function much, or is it a superfluous feature?

It's actually funny to see the amount of unique views a day rising when there is a rally going.

Love the page (use it several times a day) but there's this bug:



The LAST RECEIVED field (for an address whose balance is ZERO) always shows the LAST RECEIVED of the line above it.

For example, I sent 71.12xx BTC to the address ending in xxxPFPN, and the LAST RECEIVED for it and the address below show that figure:

It's fixed now.
Well, not really fixed. I have replaced the "Last recceived" feature with the "Total recceived" feature.
