Blockchain.info - Bitcoin Block explorer & Currency Statistics

[Proofer]

Thought I'd point out a grammar mixup on the wallet page,

"1000's of Merchants accept bitcoins worldwide already accept bitcoin with new ones joining everyday."

probably should be,

"1000's of Merchants worldwide already accept bitcoin with new ones joining everyday."

If you're being really picky, "1000's" should drop the apostrophe also. Or just spell out "Thousands."

And to be really really picky, "everyday" should be "every day," although the one-word usage is now quite common.  In traditional standard English, "everyday" is an adjective meaning ordinary or commonplace ("he wore his everyday outfit rather than dressing up"), while "every day" means each day.

Let's say I'd like to use Blockchain.info's API in order to vet new unconfirmed transactions for possible double-spending attempts. Do I use the "double_spend" key? Is "relayed_percent" a good metric?

Use both.

Thanks a bunch.

Why there is no "Spent" link on the second output ?

Fixed now.

After sending a transaction I get a change transaction that I cannot use for spending in a new transaction until the previous transaction gets a confirmation.  Wouldn't there be a way to let me spend from the output of the change?  Perhaps if, in the original spend, I were to use the mode where I can specify the address for the change to be sent to -- and select the input and change address to be the same address?

[DeepBit]

Unconfirmed transactions list shows e63a323bb7475c32881517380fa54637ffbf6b891eb5fcc08ff50ffe666524cf as Fee: 0.7415 BTC - Size: 2235 bytes, but actual fee was 0.0015 BTC

The ability to edit address book labels, and receive address labels seems to have vanished.

.. or perhaps I'm missing something obvious.

I could really use "receive address" labels. It seem you can currently only label "send addresses". I have quite a few receive addresses and since each one refers to some event or place I sent money it would be really useful to label them. Also some users have made mistakes in the past sending to an address they didn't intend and labels would make that much harder to do.

The label address button has been moved to the QR Code dialog.

Indeed it has.  Thanks.

is anyone else having login trouble?

[DeepBit]

is anyone else having login trouble?

Yes.

I created a test wallet with a couple of bitcents in it, just to evaluate the site and now it says that my password is wrong :)
Luckily I have all the privkeys saved.

[Stephen Gornick]

I was able to login just now without any problem.

There was a change made to wallet encryption a few days ago.   Is this your first login since then?

P2SH now fully supported in the block explorer

e.g. An address (always starts with a 3)

Cool, but it says "0 BTC received" :)

Yes I login many times today. I also use a yubikey. It shows error decrypting password. I made a test wallet and login fine.

Might be an issue with auto-detection between old and new wallet formats. Please try again now.

Edit: Also next time you login please run the "Integrity Check" found in the Account Details tab.
