1  Bitcoin / Bitcoin Discussion / How do other blockchain implementations affect Bitcoin? on: August 02, 2014, 08:05:54 PM
I know that the blockchain technology which is the backbone of Bitcoin has lots of other applications.  For example, it could potentially be used by companies to issue shares of stock, or for two individuals to construct a public contract.

My question, and I realize this probably requires speculation, is as follows:  If this type of behavior caught on, would it provide support to the bitcoin network/currency?  Since the bitcoin blockchain is by far the biggest/strongest/(most stable?) does it make sense for these contracts to exists on the same blockchain somehow?  Or would they simply exist as completely separate entities, using the same technology (the blockchain concept)?

I am both an investor and an enthusiast.  When I explain bitcoin to friends/family, I cite the "alternate blockchain usage" as a potential support for bitcoin as a currency.  But I am unsure if this make sense in theory.
2  Bitcoin / Electrum / Question about Electrum seed and multiple addresses on: February 19, 2014, 09:44:23 PM
Just a quick clarification.  Say I create an electrum wallet and it automatically generates me 5 addresses.  I save the seed.  I receive bitcoins at multiple addresses, causing electrum to automatically generate me new addresses.  In the end I have bitcoins stored at 30 addresses in my one Electrum wallet.

Now my computer gets fried.  I buy a new computer and install Electrum, and re-create my wallet using the seed.  Will all 30 of my addresses (and coins) be restored, or only the original 5?
3  Bitcoin / Electrum / How does the seed-backup and encryption work simultaneously? on: January 29, 2014, 07:27:32 PM
I want to have a complete understanding how the electrum client operates.  I understand that when you generate your wallet, it provides you with the 12-word-seed as a backup.  So if I lose my wallet, I can re-create it with the seed.

My question is, does that re-create an unencrypted version of the wallet?  So if my wallet is encrypted but someone somehow stole my seed, could they steal my bitcoins without knowing my encryption password?  Or does the seed re-create the encrypted wallet?  If that's the case, wouldn't changing my encryption password render my seed useless?

Or is it simply the case that my seed is paired with a static encryption password, and if I change that password then proceed to lose my computer, i would need to resort back to my original password after i recover my wallet?
4  Bitcoin / Bitcoin Discussion / What would a fake transaction look like? on: January 24, 2014, 10:51:00 PM
What I mean is, I've heard it's possible to pretend to send bitcoins so it shows up on the blockchain as unconfirmed.  How easy is to do this?  What would it look like on the blockchain... just a transaction that never gets confirmed or what?

I'm just wondering if it means anything when I buy a bitcoin from someone and it "shows up" in my wallet immediately without confirmations.  Is that any evidence that they actually sent real bitcoins or could those easily be faked?
5  Bitcoin / Bitcoin Discussion / Issue of anonymity and fungibilty for btc on: January 22, 2014, 08:00:24 AM
From what I can tell here, there seem to be two possible threats. 

Firstly that if bitcoin transactions are traceable, then btc loses it's fungibility and I understand this is a big problem.  If certain bitcoins are blacklisted or color-coded and what not, this gets ugly quickly.

Secondly, if something were written onto the btc code to make it fully anonymous, then governments may lash out against it for fears of money-laundering and such.  I realize this is no different from cash, but governments do things to combat the use of cash for illegal activity.  So without control of bitcoin one would expect they may choose to fight the bitcoin system all together.

My question isn't so much whether either of these "problems" are a serious concern for the widespread adoption of bitcoin, but rather if there is some way to resolve both of them.  Some way to make one bitcoin indistinguishable from another, while not being a safe haven for illegal activity.
6  Economy / Currency exchange / WTB up to 5 bitcoins, paying with Pokerstars or Skrill USD on: December 09, 2013, 03:59:49 PM

7  Other / Beginners & Help / Did I just get sold fake coins? on: November 19, 2013, 12:12:08 AM

I realize I should be more careful than I was, so I'm not trying to speak badly of bitcoins or anything, I just want to understand what's going on in my situation.

I arranged to purchase bitcoins for an online $ transfer with someone I don't know all that well.  We agreed on a price and I sent for 0.4 coins.  He received, and said he sent me 0.4 bitcoins, which showed up in my client as unconfirmed.  I figured these were legit coins, so I send $ for 0.5 worth of coins.  At this point, he claims to have sent the coins, but nothing is showing up in my wallet.

However, on the page for my wallet's address, the 0.5 worth of coins are showing up.  In fact, they are showing up twice.  So my "final balance" reads 1.4 btc on blockchain, but all 3 transfers are unconfirmed. All that's showing up in my bitcoin client is the 0.4 transaction, which is still completely unverified (it's been about an hour)

He claims he may have "accidentally clicked send twice" which is why the transaction is showing up twice.  What are the chances this is some kind of glitch I don't understand, versus him doing something to send the illusion of bitcoins while actually stealing from me?

My wallet is showing 0.4 bitcoins
My address on is showing 1.4 bitcoins
How is that possible?
