Blockchain.info - Bitcoin Block explorer & Currency Statistics

[chrisrico]

why is the public key of my bitcoin address  on blockchain.info   130 character while the scriptPubKey on bitcoind is 50 characters?

The name scriptPubKey (despite its name) is only a hash of the public key with some op codes. The scriptSig (on the input) is what contains the full public key. The standard transaction is like

Code:

OP_DUP OP_HASH160 <pubKeyHash> OP_EQUALVERIFY OP_CHECKSIG

and the scriptSig is like

Code:

<sig> <pubKey>

(source).

Nice to see the blocks of Asicminer in the Pool Pie!

But when clicking on it (or viewing with the API/JSON)
https://blockchain.info/en/blocks/Asicminer
http://blockchain.info/blocks/ASICMiner?format=json

They seem to mine every block

Would be nice if this can be fixed!  

Because I got no reaction after 1 week, I'm asking it again  

Can the JSON please be fixed?

It's probably very easy to fix, but now it's very difficult to get the mined blocks of ASICMINER from the last 48h or days because
the '48 hours' and '4 days' from https://blockchain.info/pools?timespan=48hrs aren't also working..
_{(It only shows the last 250 mined blocks, so it's going back for max 1.7 days or so..)}

Everytime i want to login into my wallet and i enter my alias i get a "Authorize log-in attempt" message.

Email only states the attempt that i made few seconds ago...

It's annoying... can i turn this off?

If you login successfully once your browser should be remembered for up to 1 month, is this not happening? To avoid these messages you can use the direct link from the welcome email to login rather than using the alias but they cannot be disabled currently.

It remembers the browser until some other alias is entered in. So, if me and my GF share the same computer, we have to reauthorize the aliases all the time. It's annoying.

Please allow the user to decide if re-authorization is needed in case someone uses existing alias (and make it ON by default).

I believe we are getting too paranoid here...

After recent thefts from blockchain.info, you can't be too paranoid.

Thanks for the fix!

But is there a way to go back for more than the ~30 blocks now? (1.5 day)

@Piuk: Would you possibly be able to strip white space when importing a private key.

Amory and some other clients split the private key with spaces to allow for easier reading, however with these spaces your service doesn't recognise it until they are removed.

Thanks.

Edit: Bug.
When signing up for a wallet, the first captcha entry always fails. Tried this numerous times over the last few days on various browsers.

piuk,

I'm trying to transfer BTC from my blockchain.info wallet and I get the error message: "ReferenceError: Can't find variable: precisionFromBTC".  Any idea what is causing this?

Thanks

In case puik does not answer: Have you tried clearing your browser cache, it often solves this kind of problems.

I am not receiving SMS for my 2 factor authentication so I can't log in since yesterday. Anyone else having the same issue?

I'm in the UK.

[SOLVED]
puik,
 just to bring to your attention that https://blockchain.info/api/json_rpc_api does not allow connecting using SSL on port 443 only non-SSL on port 80. Sending username/password in plaintext is not an option for me. Could you please fix that and let me know when SSL can be used?

[dansmith]

@maraoz

THanks for the heads-up. SSL works for me now. Probably some temporary glitch on blockchain.info yesterday.

I created a 2-of-3 address as described here: https://people.xiph.org/~greg/escrowexample.txt
Then i sent some BTC to that address (32UQPBzLuYMGYCSkSK4YYSFD8BHBrJNmJC) using blockchain.info JSON RPC.
The resulting transaction is https://blockchain.info/tx/a3b2c1db9424a0623aa92e2ec512f6ff26401c51726151cab842dbaffc2fe81e
The BTC went to a completely different address 3JNaZ9A1yMpRTGyoG9Vq9MvvjKcECYbSoo

Any explanation for that behaviour?

If you still have the exact command you used to send the tx to blockchain's json-rpc, then some diagnose might be possible.

Even if you don't, you might be lucky, as the different address might just be the consequence of specifying the pubkeys in wrong order. In that case, you and the other one would just need to redo the creation of the multi-sig address as you did it for the spend, and nothing lost.

Also, there was recently a problem (that was quickly fixed) about eventually showing the pub-key for an address of yours in a wrong format. It's not likely to be the case, but if it was, then there'd still be hope for your funds...

[dansmith]

I imported all three private keys of the 2-of-3 address into bitcoin-qt and the "lost" coins popped up in my wallet.
The receiving address, though, is 32UQPBzLuYMGYCSkSK4YYSFD8BHBrJNmJC - the one I sent to initially.
Bottom line:
blockchain.info has some issues with multisig addresses.

Thanks for the assist, but it appears to have resolved itself.  I'll be sure to try your recommendation if I happen to encounter this issue again in the future.

The websocket API is great - thanks for making it available.

I'm working on a tutorial for how the blockchain works that uses real time data and if you could add an optional argument to the ping api:

{"op":"ping_block", block_hash}

it would allow the tutorial to browse some recent blocks immediately after it's opened.

Cheers,
Steve

Is there a way to show the found blocks in the last week instead of the last 250? _{(which is less than 36 hours)}

http://blockchain.info/blocks/ASICMiner?format=json

If not, can you please create it? (a parameter like ?showthe250blockslfoundafter=239000) is also fine to reduce the bandwidth

Thanks

Looks like a broken link:
https://addons.mozilla.org/en-US/firefox/addon/my-wallet/

Returns "We're sorry, but we can't find what you're looking for."

Chrome link works fine, though.

FEATURE SUGGESTION:

Simple queries feature:
example

SENT BY 'sender'
TO 'addr1' OR 'addr2'
AMOUNT < 1

application example

SENT BY '1dice8emzmqkvrge4qc9buff9px3xaydp' TO '1CasperDEhyGD81WNPo9qkaFnWxUSWmrqk' AMOUT <1 to get all SDICE TX to me which is  < 1BTC

example 2: SENT BY '1CasperDEhyGD81WNPo9qkaFnWxUSWmrqk' FEE='0'

Is it possible for your system to handle these quries? Also, we'd like to see there are some good UI to do all those stuff

Feature request:
Please allow the Android App to import private key by typing it. (copy and paste).
I was importing a private key and I needed two mobile phones, one to create a qr code and the other to scan it.
