If a redeeming P2SH transaction (or any transaction for that matter) is validated by the network (and I know it hasn't been spent yet), do I need to keep the "in" part of the tx or can I scrap it out? If I understand the protocol, I can left it out; in that case I fully support P2SH as the space savings in the future will be HUGE.

So not to fragment off but the reason why auto refunds can't be done is becuase the person that is supposed to recieve the refund has the other half of the "key" to commence an action(such as unlocking and sending back to wallet). Is this correct?
Correct. It is the same reason the merchant won't "automatically get paid". They need to sign off on the "forward" transaction also. In a 2 party transaction both parties must sign the transaction even if it is obvious to the humans that they will want to sign it. Granted some of this can be automated by the wallet. You could get a popup "there is a half signed transaction to receive 50 BTC @ addresss xxx we control. should we sign it to complete? yes/no/more info". Did anyone read my reply? Example, I am the buyer and I have this transaction already signed by the seller: This transaction sends 1 BTC to {seller}. To be valid, have this signed by {seller} and {buyer}. If I want to release the escrow, I sign it and publish it. The seller automatically get paid.

It IS possible with just multisig: You have 2 transactions, one that we'll call XtoA that sends the coins to A, the other, XtoB sends the coins to B. X is a script that require the transaction to be signed by both parties to be valid. A signs XtoA and B signs XtoB. In the moment A signs XtoB, it becomes valid without B interaction; and viceversa. No need to do use sequences or anything. Am I wrong? P.S: As others said, the idea is anything but new. Satoshi himself proposed this: https://bitcointalk.org/index.php?topic=750.0I would prefer a 3-way escrow where a third party will be contacted (and payed for the service) automatically when there's a dispute and it has the final word. Either thing is possible with P2SH I think.

In fact, Strongcoin is a modified version of Diaspora integrated with Electrum lightweight Bitcoin client ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) I have no idea, and I don't know if they fixed the problem. I haven't used strongcoin since I opened this thread. I use blockchain.info and the official client importing the keys with pywallet.

It would be great news! Until then, it seems you can already buy on amazon with this: http://spendbitcoins.com/Has anyone tried that?

I forgot to save some of my outgoing messages from me. Anyway it's clear I sent him 39 BTC from the messages I have. I don't know what to do with them, though. I also live outside US (I'm from Spain).

Hi DiThi,
I have been unable to replicate this using blockchain.info. What browser and OS are you using? Could you please confirm the exact steps to replicate the bug and if possible include a screenshot of the transaction confirmation dialog.
For example this transaction of 0.999999 appears to be constructed correctly.
You are right. I was about to send you an example but there was an error on my part when interpreting the tx. Thumbs up for such a great web app. By the way, it says "A 1% or 0.01 BTC fee is charged on all outgoing transactions". 0.01 is the minimum? Fix the text to make it clear.

I was talking about "online" wallets, i.e. web browser based wallets. I use BitcoinSpinner as well and it's great! By the way, blockchain.info is down the last times I've tried to access, and I need a private key I forgot to backup :/ It's up again.

I'll use escrow services from now on. btcrow or thrucoin until escrow is built-in in the client.

I'm very interested in this, specially after I've been scammed.

He also ran with 39 BTC from me, selling his iPad 5 days ago... He said he would send it early monday. Unless I receive the iPad (which I doublt since he didn't reply), it's very probably a scammer.

He sold me an iPad for 39 BTC, 5 days ago. He doesn't reply anymore, ran with my money.
I verified his ebay account, but that doesn't guaranteed anything...

None of them can access your private keys.
The problem is that if any of these sites are compromised by attackers, and the attackers change the scripts in these pages so that they can access your private keys, this will have been a false sense of security. Attackers gaining access to change html pages is actually a fairly common occurrence, so it's a realistic threat to be aware of. It's much more difficult than directly accessing unencrypted keys, but I agree, it's a threat. Is there a browser plugin or userscript that guarantees that the code in a page hasn't changed? Or something that allows digitally signing HTML and JS.

Sorry, misleading title tag. Don't try until they confirm it's fixed.

Strongcoin. They sent me the missing 10 BTC and they're trying to fix the problem. Also blockchain.info is affected (and maybe other bitcoinJS wallets), but as I said, you can review the transaction before sending it, so it's not a problem. Clien-side online wallets are much more secure than server side ones. Don't ever use server-side wallets (such as the infamous and now extinct mybitcoin). The only client-side wallets I know are Strongcoin, Blockchain.info and Bitventory (this one may be more secure since the author can't change the code without you knowing it). None of them can access your private keys.

Edit: A fix is on the way!
A friend of mine sent 0.99999999 BTC with StrongCoin and the fee has been 10 BTC (in theory it should be 1%, 0.005 min, 1 max).
With blockchain.info, trying to do that yelds even weirder results, but hopefully that wallet is so great it lets you review all the details of the transaction before sending it. blockchain.info is not affected at all, it was an error on my part.
Please, fix it!
And to the rest of the people: don't try that at home! Well, can someone try sending something like 0.00999999 to test?

I need any of the devices listed in the title for developing an OpenGL ES 2.0 app. Max 26 BTC. It doesn't matter if it has scratches, etc, as long as it works.
Edit: I forgot to mention, I live in Spain.

Definitely this app is the way to go!
I found a bug: the app crashes when you scan anything that's not exactly a bitcoin address (e.g. a bitcoin address with leading or trailing spaces or newlines). Also some strings are not in strings.xml (and therefore, not translated in any language).

Count me in! 1BTC per org, 40 BTC max at the moment. I've sent 1 BTC. I may send some more later...
