1081  Bitcoin / Bitcoin Technical Support / Re: What happens to unconfirmed transactions? (blockchain.info) on: April 24, 2013, 10:11:13 PM
This would make bitcoin unusable for micro payments.

Bingo!

At the time the logic was developed, a 0.01 BTC payment was a "micro transaction".  Now at an amount over a dollar fifty, there are payments which that you'ld think would not be considered micro transactions but the network does consider them as micro transactions.

Paying a fee resolves that.

The Bitcoin-Qt/bitcoind client would have insisted on a fee in this instance.  Blockchain.info/wallet ...  not so much.
1082  Bitcoin / Bitcoin Technical Support / Re: What happens to unconfirmed transactions? (blockchain.info) on: April 24, 2013, 10:09:11 PM
It has been over 30 hours since that transaction was submitted. Is it possible that it can still be confirmed?

Well, the transaction won't even be relayed by the Bitcoin-Qt/bitcoind client because it has an output below 0.01 BTC.

If you had made this transaction from the Bitcoin-Qt client, it will continue to try to re-broadcast the transaction, maybe hourly, and presumably eventually it would reach a miner directly and eventually get mined.

Blockchain.info/wallet doesn't seem to re-broadcast indefinitely.  It seems to abandon a transaction after a certain period of time passes and the transaction doesn't get a confirmation.    The transaction then disappears from blockchain.info/wallet as if it had never been made.

If you need the fund, you could import the private key that spent the funds to another client and try to spend the funds that way.  Of course, that is a double spend and all the other transactions you made using that coin or any children transaction would instantly become invalid.

when I try to download the client I get an error!

Installing an executable from an untrusted source?

Good luck with that.

The easy solution is to just send your coins to yourself. This will push them past the fork on the LinearCoin chain.

There's no difference between an address created using Bitcoin-Qt/bitcoind versus inflatacoin LinearCoin.  So me sending to my own address is a transaction valid on both chains.  

So the private keys in my LinearCoin client would be as valuable to an attacker as my Bitcoin-Qt/bitcoind wallet.dat.

I personally am not a thrill seeker who jumps off bridges tethered by a bungee nor does playing Russian roulette appeal to me.  Trying to use LineaCoin without losing my bitcoins seems like an equal challenge.

Changes to Alias Resolving

When a wallet is accessed using an alias if the browser does not already have the wallet identifier saved or have an authorised login session email authorisation will now be required.

I'm not sure this is working.  On a new browser with no cookies or other local storage (Chrome in icognito mode) I enter my alias for Identifier.  The page is reloaded and the ID field remains blank.  Then in another tab I go to Blockchain.info/wallet and there is my identifier.   So the challenge is defeated somehow.

I am planning on donating to Freebanking.org as a sort of insurance (and big Thankyou).

If you figure out a way to donate using bitcoins, please share.  I only saw PayPal.
1087  Bitcoin / Project Development / Re: [ANN] coinwidget.com - a Bitcoin Donation Widget on: April 24, 2013, 10:30:23 AM
Please share any ideas or suggestions you may have to improve on this widget.

Thank you for providing a useful donate button (script and graphics).

I do believe the method offered for use could be made more secure for the site operator.  Currently, your site has full access to replace the bitcoin address.  And without HTTP everywhere, there is the opportunity for a MITM to alter the contents, substituting the bitcoin address with another.  Being that these are for donations, I might not even realize that this is happening.

The javascript could be revised so that it could site on my host, or in the same .html as my page.  That would be safer.

With this service, you can pay your bills with Bitcoins.

Is this payment sent by check only, or is the USD payment delivered electronically?
1089  Alternate cryptocurrencies / Altcoin Discussion / Re: I will create a forked bitcoin chain on: April 24, 2013, 07:48:57 AM
But you all missed the TRUE OP's goal :
to confuse/delude(or defraud ?) as many Bitcoin users as he/she/CIA can...

Based on the comments right after yours, it looks like that attempt is successful, unfortunately.

1092  Alternate cryptocurrencies / Altcoin Discussion / Re: I will create a forked bitcoin chain on: April 24, 2013, 04:06:30 AM
But they do relay new block announcements. Even if they are off the current chain. Right?

Nope, for two reasons.  Firstly, only if the block is of a greater height than any block the client already knows about will the client then relay it.   Secondly, the amount of coin generated (200 BTC) would fail the block validation logic (as it exceeds 25 BTC at these block numbers), so the Bitcoin-Qt/bitcoind client would reject the block and, of course, not relay it.

1093  Economy / Trading Discussion / Re: MTGox to UK bank on: April 24, 2013, 03:52:43 AM
thanks, do you know if there is a possibility I can ask my bank to give me USD and I change myself? OR - dare I say it, should I just ask my bank about this Smiley

Some UK banks allow foreign currency (e.g., USD) accounts as well as domestic currency (GBP) accounts, though that isn't common as far as I know.

Citibank UK offers it:

HSBC too:

1094  Economy / Services / Re: Getting difficulty level imported into Excel on: April 24, 2013, 03:42:47 AM
Currently I am importing it from a website, but when the website goes down it messes up everything for me. I need this for other coins than bitcoins so there really are not a lot of good stable sites to grab the difficulty level from.

If you weren't aware, from the Bitcoin-Qt/bitcoind client there is getdifficulty API call:

Other clients might have similar capability.

Eric Schmidt:
Quote
"Bitcoin is a technological tour-de-force, what I don't know is whether ultimately it's going to be legal; because all money structures need legality for various reasons, including fraud and those sorts of things. It's too early to say."

Bitcoin doesn't help Google.  Google does quite well with the restrictions in place today.  It doesn't have to compete with individual engineers raising capital on their own through equity crowdfunding.  Instead because the State doesn't allow engineers to raise capital thorugh equity crowdfunding, Google gets to hire those engineers instead.

Fortunately, Bitcoin doesn't need Dr. Schmidt to look favorably on it.   The market will decide if there's a place for Bitcoin.

1096  Bitcoin / Development & Technical Discussion / Re: From address on: April 24, 2013, 12:05:59 AM
As you might notice from my sentence.. first few words indicated that I have researched it, but since I haven't found anything useful, I thought I'll ask for help.
And instead of asking it, it would have been very nice of you to point me to the right direction.

The word "sender" may be confusing.   There are INPUTs and OUTPUTs in a transaction.  You are asking how to know what were the INPUTs to your transacion.

Raw transactions API will give this info.  Here's a thread on it:

As was pointed out, getrawtransaction <txid> 1    will do the decode for you.

So given a trasnsaction hashi, get the raw transaction then decode it to get the UTXOs used.

[Edit: And the typical disclaimer here ... payments from a hosted (shared) E-Wallet account will show an INPUT that is not for the same E-Wallet account as the party that sent the payment.   That's why SatoshiDICE includes the warning about only using approved clients like Bitcoin-Qt/bitcoind, Multibit, blockchain.info/wallet, etc., and to not send from an exchange or hosted (E-Wallet) services.]
1097  Bitcoin / Bitcoin Technical Support / Re: Yubikey (general two factor auth) question on: April 23, 2013, 10:54:06 PM
Can I use it as a two factor auth for ANYTHING ?? or are they specially designed for BTC wallets ?

If you want to use a Yubikey with Mt. Gox you need to order it from Mt. Gox.   

There are other services which use Yubikey.  That Yubikey from Mt. Gox is customized and will not work with other services.  You can use a Yubikey obtain from Yubico with those services.   

You don't want to share the same Yubikey with more than one service.

1098  Economy / Trading Discussion / Re: MTGox to UK bank on: April 23, 2013, 10:23:40 PM
or will I receive USD into my UK account and then change myself from there (preferable as I know some good methods of exchange)??

Yes, you would withdraw USD as an International bank transfer and your bank would do the conversion to GBP (less conversion fees).
1099  Economy / Service Discussion / Re: UK Funding options on: April 23, 2013, 10:21:40 PM
What's the catch?

Mt. Gox got rid of redeemable codes.  There no longer is a path from Mt. Gox to AurumXChange.

Does anybody have any tips/best practices for doing this? Outside of the obvious such as meeting in public, etc etc - more on the mechanics to make sure both of us fulfill our ends of the bargain.

Tips for local transactions
