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?

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." Tongue

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.

Couple of updates:

P2SH now fully supported in the block explorer

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

https://blockchain.info/address/3Dnnf49MfH6yUntqY6SxPactLGP16mhTUq

Transactions will show the deserialized script:

https://blockchain.info/tx/6a26d2ecb67f27d1fa5524763b49029d7106e91e3cc05743073461a719776192

Wallet encryption changed slightly

Wallet format changed to Block mode CBC ISO10126 padding with more PBKDF2 rounds. It will be re-encrypted when you next login.

Simple My wallet API Now Available

https://blockchain.info/mywallet_api

The requirement to share your password will be removed when P2SH is ready. I need the api now to implement so new features internally.

Lots of new features coming later in the week.

Rassah And BkkCoins: Sorry I haven't got a proper response yet, need some time to look into your bug reports.

Which address do you have in your wallet 1MSDPEP5HukXi8LQG6dP9EU5HWZoNKzaXX or 14avxyPW5PgA68kGkDkY1mCGPP8zqkywEx?

1MSDPEP5HukXi8LQG6dP9EU5HWZoNKzaXX is mine ( a change address ).
14avxyPW5PgA68kGkDkY1mCGPP8zqkywEx is April BitLotto address.

Note, my account balance appears to be correct so this dropped 0.25 is subtracted but not shown in red.

Edit: I thought the explorer non-advanced mode and wallet were showing the same. But now I re-checked the explorer non-advanced and it shows the 0.25 output whereas the wallet does not. Either you just updated the explorer code but not wallet or the wallet is actually using different logic than the explorer.

To make the blockchain easier to understand Inputs are grouped by address in default mode. If you view it in "Advanced" mode (bottom of the page) if you show you the true inputs:

https://blockchain.info/tx-index/3099094/f08f16cb4acac8e334d4e99155085cd5f03730936b06e1ea68c2d1fd0ece18d2?show_adv=true

Unfortunately Advanced mode isn't available in My wallet.

Same with the missing output on:

https://blockchain.info/address/1MSDPEP5HukXi8LQG6dP9EU5HWZoNKzaXX
This is odd because it shows up in non-advanced mode in explorer but drops an output in the wallet. In the ledger this transaction shows as receiving money (green) rather than spending money (red). This was a purchase of BitLotto for 0.25 btc so it should definitely be a spend.

I have Advanced:Disabled in explorer and it still shows the duplicate input and 0.25 output. I don't know how a duplicate input from the same address occurs. Nonetheless, my ledger shouldn't drop the spend and convert it to a receive... right?

Edit: Ok. just checked again and see I am in Advanced mode in explorer since the button is Disable to turn that off. I still think the transaction is misinterpreted by the wallet because it really should not show up as a receive instead of spend. The actual amount (0.25) is gone and I cannot see that BitLotto purchase.

If you compare the difference between normal and advanced the direction of flow should not reverse and output disappear.

Just helping you fix'er up a bit - not trying to be nasty.

Thanks, I've made the changes to my local copy. Will show when I push an update later int the week.

I have a transaction that shows up correctly in the explorer but is missing an input and output in the wallet ledger.

f08f16cb4acac8e334d4e99155085cd5f03730936b06e1ea68c2d1fd0ece18d2

Maybe it's related to the address 1KToDEnWP9vzBFYgyJrRo1ahGLyWY1VNxq
being an input twice (only shown once in wallet ledger)?

The output for 0.25btc  address
14avxyPW5PgA68kGkDkY1mCGPP8zqkywEx
is not shown in the wallet ledger.

Edit: Had JS errors - didn't know a new version of FF Add-on was out. Old version caused JS errors but FF didn't restart after new version so was not active. Ok, now.

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."

And one small one on sliding panel 5 (charts) - "you" should be "your".
Also on panel 3 run-on - should start a new sentence after "saved locally".
Also in Retain Control section,
"ability for to access your money"
should drop "for".
And in section, Open Wallet, "Where to spend My Coins" this,
"Also check Bit-pay.com's fatured merchants."
And in "Account details", "Secret Phrase", this phrase,
"help us verify your identify" should be "identity" I think.

Also, might I suggest a finger pointer cursor for the main menu buttons - better than text caret,
eg. in css file,

ul.pills li { cursor: pointer; }

Please check the dendrogram of d0636198ea55fadee5b4ccc07c85012db7d07c2d25790b3aec770c86617801c0 transaction - one of the outputs is shown as going to 1D6mjWev7NnbPdCQQznMxxFxBk6HadixS2 instead of 3Dnnf49MfH6yUntqY6SxPactLGP16mhTUq

P2SH isn't fully supported yet. I use byte[20] to represent a bitcoin address in a few places so cannot yet distinguish between a normal pub key hash and and P2SH hash. I will fix it before April 1st but before then P2SH hashes will behave weirdly.

While the above chart seems to work fine, I do see all recent blocks as orphaned. I suppose thats a related problem?

Server down captain!

One server just stopped responding, not sure why. Should be able to run without it until I can get a restart on Monday.

None of the charts are working at the moment.

That transaction was mined, but never confirmed. So while blockexplorer.com and my Satoshi wallet reports the address it was mined to as having 0 balance, your wallet still reports me having something like 0.074 from that transaction. I think that was also what corrupted my wallet, and made Bitcoin crash every time I tried to send any wallet. I extracted all the address private keys using pywallet and emptied them all out one at a time, including this one, so my Bitcoin is safe, but while my wallet says this account is 0, blockchain.info says it's not.
Just a heads up on a possible bug or something.
