Blockchain.info - Bitcoin Block explorer & Currency Statistics

[johnlu]

piuk, it would be really nice if you add an option in android client to require a pin or something to access the android wallet. How do you see this suggestion?

Is BC down?

Getting all sorts of random errors?

Also check this tx, I think the miners fee may be a tad high!

A negative miners fee!  Somebody must have played with raw transactions.  I assume it will never confirm, but how on earth did it propagate?


EDIT: The outputs have been spent.  Surely, somebody is trying to creating correctly-looking transactions that will never confirm probably attempting a double spend.

So the miners fee is actually low? So ho do I get my coin if it does not confirm? There is no double spend message anywhere..

[piuk]

Dunno if anyone noticed the "Cancel Transation" button but it's missing a c if it means to be TransaCtion.

Fixed.

Yep a custom transaction submitted to /pushtx. Bitcoinj validates scripts but custom validation has to be done to match the inputs and outputs etc, this was missing:

if (valueInput < valueOutput) {
      throw new ValidationException("Value Input: "+ valueInput +" < Value Output: "+ valueOutput +"");
}

The miners fee is negative, it is guaranteed never to confirm, and the transactions building on this one will never confirm either.  Presumably the transactions will expire after a day or two, and the money will be back in the sender's wallet.

If you are at the receiving end of any of these payments you will not see the money.

Something is wrong with blockchain.info

When I try to search an address, it returns this:

Code:

Got error 157 'Unknown error code' from NDBCLUSTER

Example: http://blockchain.info/address/1Kf1nT7jQnFC7N3tSdgg5qKGTV4MucfpBg

I got a different error:

Got error 1 'Unknown error code' from NDBCLUSTER

Freaking My Cluster is driving me insane.

[piuk]

So it doesn't seem to like your SSL cert.

The SSL cert for coinad should work correctly now.

YES!
Thank you!

can we get address searches to be https:// ?

I may have found a bug.

I sent the following two transactions 15 hours ago using my blockchain.info wallet on my iPhone:
http://blockchain.info/tx/56c41c6a98d94a2b338d684aedae46a4a481eb1e11c25c042bb017b936414630
http://blockchain.info/tx/eba76d7b7c5b13927681c9441e64c666f3e585df179f2a246ddd17cf5b2baf83

None of them have confirmed.

Both transactions are small (257 bytes), standard, and have a 0.0005 fee. Plain vanilla.
Nevertheless, I never saw the transaction in the memory pool of any of my own nodes, so I believe that they were never broadcasted from blockchain.info which would explain why they have not yet confirmed.

Did anyone experience something similar recently?

blockchain.info isn't calculating firstbits for new addresses. Could you fix it please?

Yep, Fixed.

None of them have confirmed.

I have rebroadcast them and they have both confirmed now. Perhaps an issue with automatic rebroadcasting.

Ah for some reason I disabled this. It is enabled again now but has a bit of catching up to do.

Scheduled Maintaince

Friday 22nd 10:00am approximately 30 minutes.

I know there has been a fair amount of downtime recently but in the interests of improving the situation a bit more downtime is unavoidable. An additional server is ready to be installed but there isn't enough space in the current rack. The servers will therefore be moving to a dedicated quarter rack, which means more room for future expansion and a private locked cabinet for improved security. It should just be a case of powering down and up again so it will probably be less than 30 minutes.

Piuk - do you run bitcoind or your own implementation of the protocol?

[paraipan]

Hi piuk, can you please fix blockchain.info's transaction routine? I have it set-up to pay the hefty fee on all my transactions, and form time to time it just chooses to send a fee-less transaction. This is not acceptable dude  

Can you link me to an example transaction that the fee should be higher.

Yes, PM sent

Sorry for making you lose precious time with me.

Typical PEBCAK issue here, the fees were set to normal in my blockchain.info account and when using old enough inputs the miner fees were not included.

Hi!

Blockchain.info is a great service! But I got a small problem with it.

Is output https://blockchain.info/q/newkey actually correct?

I assumed it returns a bitcoin address and a private key for it.

So I generated a pair using this API call and sent 0.01 btc to bitcoin address to test it. And now I can't spend it using the private key.

I converted the private key to Base58 via brainwallet.info and tried to sign a message... and noticed, that it showed a different bitcoin address (not the one that had been given by https://blockchain.info/q/newkey).

This is reproducible for me. The newkey call broken? Is it possible to recover my test funds?

Thanks!

It works fine for me.

I used http://brainwallet.org/

Then I clicked the "Secret Exponent" button, and entered the private key received from https://blockchain.info/q/newkey in the "Secret Exponent" field.

When I clicked the button for "Compressed" key, the displayed Bitcoin Address was the same as the one given by https://blockchain.info/q/newkey

Are you sure you are using "compressed key" when generating the Base58 code and Bitcoin Address?

Hmm.. You are right, I used a different procedure. I used "converter" tab to convert to Base58, and then used Base58 on the "sign" tab. And it showed different address. So maybe I'm just misunderstanding something, sorry.
