Ok.. So new_key returns bitcoin address and exponent for private key (not a private key itself)?

When I put it in brainwallet, it gives the right bitcoin address... So it means that theoretically I control my test money. Thanks for help!

But now there is a question, how to spend them practically via blockchain API?

I want to use this call:
https://blockchain.info/merchant/$guid/payment?to=$address&amount=$amount

According to brainwallet doc,

Quote

$guid can be replaced with a hex encoded private key and the password parameters can be omitted.

I tried to convert private key from DER to HEX format via brainwallet's "converter", but when I feed the result string to blockchain, I get

Quote

{"error":"Invalid PK Bytes Length"}

How do I get a hex encoded private key?

Thanks!

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

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).

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.

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!

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 Undecided

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.

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

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

None of them have confirmed.

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

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

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.

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?

The SSL cert for coinad should work correctly now.

YES!

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:

Code:

Got error 1 'Unknown error code' from NDBCLUSTER

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..

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. Sad

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

Fixed.

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

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:

Quote

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

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