I wrote a concise answer that if understood allows one to comprehend the technology of Bitcoin. How DannyHamilton has the patience to keep writing the same answers repeatedly to noobs I cannot fathom.

1062  Other / Beginners & Help / Re: Bootstrap.dat takes more than 10 hours to update the whole blockchain on: April 22, 2013, 11:35:45 AM
I am running bitcoind for the first time, mine is at 218590 blocks at the moment and it looks like its only getting 2 blocks per minute now.

Is it normal that bootstrap.dat (4.5gb) takes more than 10 hours to update the whole blockchain?

Hi Abdussamad,

I  have read about electrum before but is it usable for a bitcoin payment gateway system?

Btw, I found out that using the new version 0.8 it only takes a couple hours to process the whole blockchain.

The bootstrap.dat torrent includes blocks up to 216116, the complaint is about speed after this point.
The quotes above show the original poster already found out his problem is from not using the newest version of Bitcoin. No need to respond.

It seems reasonable for him to protect himself from people who would get the gold if gold price goes up, or ask for a refund if BTC price goes up.

This is just a scumbag site that runs every URL through coinad to show people ads, and subjects visitors to unattributed copypasta in Comic Sans. It was created on the free Webs.com.

There's still a box on this site "put in your address and we will send you some coins". This guy's concept was to put people's addresses into another faucet, not give them any money himself.

I cannot afford to purchase coins at the moment, the aim of this site is to help out beginners.

See link in signature below for a web site with only original content, web hosting I paid for myself, and not a donation address or ad on it. Nor are there any promises to give you the equivalent of a free 0.0001.

I just did a Googling, and found a follow-up story from Apr 24 1953, the guy didn't go to jail (which he probably didn't regret come 1955 or 1957):

OKLAHOMA CITY (AP) - A man who wanted to go to jail for five years to be with his pal waas freed yesterday by District Judge Clarence Mills despite his protest.

  Oscar Lee Clark had pleaded guilty to a car theft charge earlier in the week. He asked for a five year term like the one given his friend, Leon Wilkerson, who was sentenced for car theft and burglary.

  But Clark had no previous convictions, and an assistant district attorney recommended a suspended sentence. Clark said no thanks, he wanted to go to jail. He had agreed with Wilkerson they would stay together, and he wanted it that way.

  But Judge Mills paid no heed. "This doesn't make sense," he said. "Everybody that comes before me wants out." He suspended Clark's five-year sentence.

I was reading an Apr 21 1953 newspaper, with stories in it like the FBI arresting a union leader who "lied" about not being communist, and came across this gem (I had to type for you):

 OKLAHOMA CITY (AP) - A 47 year old man chose five years in the state penitentiary rather than a suspended sentence yesterday to be with a man whose friendship he prized more than freedom.

  Lee Clark was arrested and charged with larceny of an automobile. It was his first offense. His accomplice, Leon Wilkerson, had one previous conviction against him. He was also charged with the burglary of a city sporting goods store.

  Both pleaded guilty in district court last week, and Public Defender Charles Moss recommended a five year sentence.

  But Joe T. Martin, assistant county attorney, pointed out Clarks's record was spotless prior to this offense and he was entitled to a suspended sentence.

  The judge agreed, and phoned Deputy Sheriff E. A. (Boots) Capshaw the good news.

  But Capshaw said the men would not be parted.  "That's the way they want it. That's the only way they'd cooperate with me," he said.

  He quoted the convicted pair as saying, "We've agreed we'll go for five years and we'll go together."

Slashdot? The problem with voting/autohiding systems is that they are subject to manipulation by sockpuppets, and a few missing posts can break up the flow of a conversation.

A subclass of elected moderators called voters could vote down or autohide junk posts and post count pumping. Too much downvoting and a poster could be temporarily hidden or banned from new posts.

If you just want your wallet transactions, you can do that with Bitcoin-qt. Just go to the debug console and type help for a list of options (or read them here: http://we.lovebitco.in/command-reference/)
1073  Bitcoin / Technical Support / Re: Installed linux over windows drive with my wallet.dat on: April 21, 2013, 06:27:14 AM
If the installation of Linux included a full format (probably 20 minutes of formatting on a 160G drive), then all hope is lost.

The pywallet offline scan instructions that were given scan your entire raw hard drive looking for private keys, if it can't find bitcoin keys anywhere on the disk (and the wallet was unencrypted) then there is no point spending the effort to recover other stuff.

1075  Bitcoin / Technical Support / Re: not seen in chain / transaction not found? on: April 21, 2013, 05:54:21 AM
I was just experimenting with those free sites, and yes, totally a waste of time, however... the mysterious 3 cents I got came from a request payment address I used exclusively for them. to recieve a payment 2 months after I was ever near one... seems kind of strange. also that it is a transaction that is not found in the chain. how does that even happen.

also, how are the coins useless? are they invalid? the other dollar or so I made from them was ok. I mean I won 5 dollars with it on SD, so It couldnt be bunk. It was the only BTC I could get at the time.

also. where does the BTC go if it is not recieved by the intended recipient?

All those questions are answered in my quote below. The coins are useless because it costs more in transaction fees to send them than their value. If you get hundreds of them to make a larger value, the per-kB transaction fee will be higher because the transaction to send many payments will be larger in bytes.

A: If the transaction is not included in the blockchain, it is not spent. Bitcoin shows zero-confirmation transactions as soon as it sees them on the network, but the sender could have sent the same coins to someone else with an appropriate fee, essentially double-spending them.

If the answer doesn't make sense, you should review sections on  http://we.lovebitco.in/how-bitcoin-works/

UPDATE; the satoshidice 0.0006122 bet has now entered into the blockchain (I guess it wasnt under minimum?) so I feel a little better. I would still like to know how in april, I received mystery btc with the transaction "not seen in chain" That doesnt make sense to me, plus, someone is out the $0.03 or w/ever 0.000259 BTC is worth right now. I suppose it is like finding (almost) a nickle on the street, i.e. insignificant good luck, but if my bank had weird unaccountable transactions going thru my account, no matter how small, I would demand an explanation or take my business elsewhere.

Also, multibit has been great up until a few days ago, when various bugs have been showing up. I'm dissapoint, son, cuz I still prefer it to the slow bitcoin client and the unusable (for me at least) electrum.

If the transaction is not included in the blockchain, it is not spent. Bitcoin shows zero-confirmation transactions as soon as it sees them on the network, but the sender could have sent the same coins to someone else with an appropriate fee, essentially double-spending them.

Lesson from Professor Obvious: don't send or sign up to receive useless dust with Bitcoin, always include the appropriate fee that the reference Bitcoin-qt client would have included, don't trust payments without confirmations.
1077  Bitcoin / Technical Support / Re: not seen in chain / transaction not found? on: April 21, 2013, 05:35:31 AM
Transactions less than 0.01 BTC require the minimum per kB fee. They will not be relayed by other peers if they do not include a fee.

The minimum bet on Satoshidice is 0.01 BTC, anything smaller is a donation. There is no "refusing" a transaction in Bitcoin. It would cost them money to send a payment back to you (if they got it at all, which it sound like they didn't).

The free coin sites are a scam, they are sending coins that are useless. It takes you far more effort to get an unspendable penny that you would have walked by on the street if it was a real penny.

(Note for free givers: the smallest useful payment to send someone is .001BTC since the client transaction fee is 0.0005)
1078  Other / Beginners & Help / Re: Why 6 confirmations? on: April 21, 2013, 03:18:04 AM
... (orphaned blocks worth $3,000 each).

Stupid question.  How did you assign the $3,000 value to an orphaned block?
25 BTC per block * $127.8 @ mtgox = $3195

An attempt to double-spend a one-confirmation block is an attempt to:

1. Identify a "sucker" that trusts 1 confirmation transactions,
2. Buy something unreversible (rare) that you receive in seconds or minutes,
3. Your transaction is included in a network block, you have one confirmation,
4. You need to independently create two blocks before the rest of the network creates one, or create three blocks before the rest of the network creates two, to replace the one-confirmation block with one of your own that sends the coins elsewhere.

The probability of being able to pull all these off is very low. #4 requires you to mine blocks that nobody else accepts if you fail, blocks that could have earned you 25 BTC.

You also must be able to afford many losing attempts to double spend - if you were buying something for 1000 BTC, you would be spending 1000 BTC multiple times before one double-spend attempt was able to refund you one of the 1000BTCs.

Satoshidice accepted 0 confirmations transactions which require 0 miner expense, had an instant reward payment, attackers only needed a 2% success rate to profit, and yet it was still difficult to pull off an attack.

Yeah right, in your dreams.
I made a statement of fact. This means it can be proven or disproven. Disprove it.

It took 10 years and 0.5% of the Gross Domestic Product of the United States to get a two-man lander on the moon. There was no toilet, they taped a bag on their butt to do #2.
The expertise to do that has largely retired or passed on. The US has no manned space program.
