Blockchain.info - Bitcoin Block explorer & Currency Statistics

[Dabs]

Dunno if it's been mentioned before, but I have a suggestion. Right now, you can click the green button to get the fiat equivalent of the bitcoin number displayed in a transaction.

I know blockchain also keeps track of historical price data.

It would be nice to see the fiat value of the transaction, at the time the transaction took place, in addition to seeing what it would be worth currently.

Hi,
I'm posting in this thread because i don't quite understand the RPC Api of blockchain.info.

I set up a node.js client and connected via my wallet credentials to the blockchain RPC API. No problem there. I can lookup my balance and stuff, all fine there.
BTW I'm using node-bitcoin.
The problem is that when i call getNewAddress i get errors and i don't know what they mean:

Code:

ChainListener.prototype.getNewAddress = function(next) {
  this.client.getNewAddress(null, function(err, address) {
    if(err) {
      console.log(err);
    } else {
      next(address);
    }
  });
};

gives me this output:

Code:

{ [Error] code: -32603 }

I also tried to put the account in:

Code:

ChainListener.prototype.getNewAddress = function(next) {

var self = this;
  this.client.getNewAddress(self.client.rpc.opts.user, function(err, address) {
    if(err) {
      console.log(err);
    } else {
      next(address);
    }
  });
};

This gives me:

Code:

{ [Error: Second Password Expired] code: -32603 }

FYI: self.client.rpc.opts.user is my account address for the Wallet on blockchain.info.

What does this second error mean. I read on the api documentation, that a second password is required, and i also set it up in my account but i don't know where to put it
in my programm.
Please help


EDIT: I just deactivated my second password and boom, it works as expected. But WHY is the RPC API telling me that a second password is required?
I don't get it?!

Code:

Method: getnewaddress
Parameters: (String label = null)
Description: Returns a new bitcoin address for receiving payments. If [account] is specified (recommended), it is added to the address book so payments received with the address will be credited to [account].
Returns: String
Second Password Required

I've sent a message to the OP. I'll be awaiting your reply.

A new address requires a new private key to be encrypted using second password. The purpose of second password is to encrypt the private keys, in addition to whole cloud-synced encrypted wallet.

Are you going to add qr scanning to the online wallet like coinpunk? It would be nice for the iOS people who can't get a good app or they are banned to have all the functionality through the web browser.

Scanning QR codes should now be possible through the web interface on iOS. I'm not sure if coinpunk is any better but from some brief testing the lighting and whitespace around the qr code need to be perfect for the code to scan correctly, not very practical for real world use.

"650 Watts per gigahash and electricity price of 15 cent per kilowatt hour."

Puik, can you readjust all the math from Electricity Consumption stats?

The current average with a mayority of ASICs miners is 15W per gigahash.

On the ticker, the 24h average is not appearing for USD:

feature or bug?

You've been ignoring my support tickets, not sure why... http://stackoverflow.com/questions/20585095/bitcoin-sendmany-with-jsonrpcclient

Disable Bitcoin-Qt Compatible JSON RPC as it is not working correctly and giving headaches to everyone trying to use it.
Point them to Blockchain Wallet API instead.

Weird -- blockchain.info is showing up in Firefox in Spanish or Portugese. But in IE it's in English.

"Explorador de Blocos Bitcoin - Blockchain.info"

Am I the only one?

Nevermind -- I just noticed the language option (dropdown flags in upper right corner) -- maybe I accidentally hit something.

Thank you! I imagine the library that decodes the picture can always be improved with time though. What library do you use?

You probably clicked a link by someone who had the selected the Spanish/Portugese version of the site. It's a bit annoying sometimes.

Hi guys,
First of all, your API is awesome, neat and does what it has to do.
The only thing, which prevents me from using it for everything:
"The minimum supported transaction size is 0.001 BTC" for receiving payments. I actually do have payments less than 1 USD, if price goes up again, this restriction may be tough for me. Do you have any specific reason for that? Is it up to date or you have it since long time ago?

Can you guys add a clean and simple directory listing on who accepts bitcoins like http://usebitcoins.info/

Hi, I just noticed that the Chinese version of your explanation about Bitcoin Days Destroyed Cumulative is wrong.
In English you write:
"Bitcoin Days Destroyed is a measure of the transaction volume of Bitcoin. If someone has 100 BTC that they received a week ago and they spend it then 700 bitcoin days have been destroyed. If they take those 100BTC and send them to several addresses and then spend them then although the total transaction volume could be arbitrarily large the number of bitcoin days destroyed is still 700."

In Chinese you write:
"比特币的天摧毁是衡量比特币的交易量所用的方法。如果有人在一个星期前，接到100比特币，然后今天花了700比特币，那700比特币天已被销毁。如果他将100比特币寄往几个比特币地址，他的总交易量虽然可能变非常大，但是比特币天摧毁数仍然为700比特币。"

The part highlighted means "If someone has 100 BTC that they received a week ago and they spend 700 BTC today then 700 bitcoin days have been destroyed."

I suggest you re-write the Chinese version as follows:
"比特币的天摧毁是衡量比特币的交易量所用的方法。如果有人在一个星期前，接到100比特币，然后今天花了100比特币，那么700比特币天已被销毁。如果他将100比特币先寄往几个比特币地址再花了他们，他的总交易量虽然可能变得非常大，但是比特币天摧毁数仍然为700比特币天。"

1. Can you please fix the custom tx fee when doing custom transactions? Right now it seems to enforce the Bitcoin-Qt default, regardless of whatever fee I specify (see also this topic)

2. Can you please add an option to record a public message with transactions that are pushed on the network manually, i.e. through blockchain.info/pushtx, just like when creating a custom tx from a blockchain.info/wallet?
(I realize this 'public message' thing is merely a blockchain.info feature, and doesn't get officially stored in the blockchain itself - that's OK)

3. Can you add support for BIP38 (password protected) private keys in the wallet?

Thanks

Hi, I recently started using the Android app and converting many friends to it.

I have a doubt and I think this might be the place to ask.

I don't understand how to use the 'address book' . An address book is usually a place to save addresses and label them, right? Like in the bitcoin-qt client. I have somethink like

I would imagine to have something like this in the address book :

Mum <address here>
Mark <address here>
Friend#1 <address here>
...


However in the app this doesn't seems to be the case. there are three tabs (active addresses, archived addresses, sending addresses). None of these seems to represent what an address book actually is.
I want to be able to store public addresses like in any other application so I don't have to rescan the QR code everytime I need to send a payment to a known address.

Is there a way to achieve what I want with the app?

If not, I'd rename 'address book' in something else since right now doesn't seem an address book.

Thank you.
