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. |

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)

... (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.  |

I would suggest you look at utilities such as pynode or bitcointools, these will allow you to dump raw block info. {"nonce": 118659259, "previousblockhash": "00000000c23d02f119cd02c894193ce12cb742ad4d0beb2dd417ce689665e7b7", "transactions": ["01000000010000000000000000000000000000000000000000000000000000000000000000ffffffff0704ffff001d0164ffffffff0100f2052a01000000434104585a0555cff21330f6948ce47f8d55565a7169ca2a9a920af3e96aa03a416c27686101af2cbcadb2a2f291a188a053174be506408e2a6d5377dea99aba816fb8ac00000000"], "version": 1, "time": 1260910240, "bits": "1d00ffff"}

Has anyone contacted bitcoincharts to see if they plan on offering historical data into the future? The hardcoded URL http://bitcoincharts.com/t/trades.csv is 503 Service Temporarily Unavailable. bitcoincharts recently removed the huge pending transaction page also, probably because these big files are an easy DDOS target. The software IS open-source: https://github.com/slush0/sierrachartfeed/blob/master/sierrachartfeed.pyIt could be modified to import any format of history file you may have, or if you are a crazy developer, you could implement a p2p price history sharing. |

If you send smaller transactions to yourself you can combine the dust transactions and create larger inputs. OK, I've sent the largest amount that I was able (200 mBTC, with a fee of 16 mBTC) to a new address in my wallet. If I try to move any of the remainder, it will be largely eaten up by high fees. It seems to me that this problem is going to affect tens of thousands of users who are frantically collecting as much bitdust as they can from all the free BTC websites. They will end up with a large balance that will be difficult or impossible to spend. Solution, warn suckers not to frequent sites that dust your wallet with unspendable crap in exchange for making you click on ads at an earning rate that translates to about $0.01 an hour. |

It is a point where the probability of an attacker being able to "cancel" the transaction by replacing blockchain blocks is remote. The original Bitcoin whitepaper has related statistics. http://we.lovebitco.in/bitcoin-paper/#ch11which means: Blocks needed before a less than 0.1% chance a 10% hashrate attacker could double-spend: 5 |

I will create a forked chain of bitcoin to accomdate for broad adaptation.
... "unless you pay me one hundred billion dollars, mua ha ha ha!" So everybody will already have their same 10M bitcoins in your bitcoin fork too, but they'll be inflated out of existence? SELL!! Target value now, 0, future value 0.[/list] |

Right so, especially .exe's claiming to be made from that code but which can't be replicated. Feel free to take the code from hashing.py and the code from setup.py and run it using the py2exe module and make sure you have all the other modules in there, you will see that the code replicates perfectly. Hashing doesn't make a password or the resulting hash any more secure Yes, I know that is why there is a new one that has encryption with it. The hashing is more to prevent against easy brute-forcing attacks which seems to be quite common in the Bitcoin community. Hope that helps out a little more, Matt. No .py here: https://github.com/matt-boyd/hasher_and_encrypterWhat's being encrypted? What encryption algorithm is being used? etc? Hash algorithms are used as a way to non-reversibly store passwords, they are what is brute-forced when a site has their password list stolen. I suggest you look at KeePass, http://keepass.info/features.html, which actually does create and store securely random passwords. |

I'm trying to understand how you expect people to use this. You say: So basically I got into bitcoins maybe two or so months ago and have been interested ever since. Due to the surge in traffic to Bitcoins, people were getting their accounts hacked due to not having very safe passwords.
I counter that people are more likely to have their passwords or bitcoins stolen by running arbitrary code posted on the forum by noobs as their first post out of newbie jail, or especially .exe's claiming to be made from that code but which can't be replicated. Hashing doesn't make a password or the resulting hash any more secure, and you certainly can't memorize a hash result. You can calculate a hash using Javascript in your web browser if you desired to do so. Where is the encryption? You don't seem to know that cryptographic hashes are not encryption. All I see is exes and dlls and no python. |

I never realized what you guys were talking about with these series 1 coins with the misprint. I could never see it. I show my wife a coin I had purchased back in 2011 and the first thing she says is "the little name is spelt wrong". I am like........huh........what? Now I finally see it, and its nice to know I have a collectors coin. True story.  That's what wives are for, picking out the details no one else would see. |

satoshidice.com resolves, I just checked three DNS servers and they all give 128.204.199.45. The (always bloated) site is quite slow to load, but it does show recent bets and such.

Without the work done by pool admins, you could have earned 0 BTC mining. A false statement. "work done by pool admins" = creating pools "you" = someone who can't properly parse English "could have" = a probability of an event taking place was present "earned" = past participle: to receive payment for work. 0 BTC = zip, bupkis, nada mining = a process with high variance where the only real "work" is finding a 25 BTC block, any other hashes actually earn nothing. |

I will personally shame anyone who calls such a thing a cash grab by the pool.
You are entitled to set your pool options any way you desire, of course. Forcing your desires upon others is tyranny. Whatever, I desire you to push the logout button. Without the work done by pool admins, you could have earned 0 BTC mining. If the pool said "we got hacked, would you like forgive some of our obligation to pay you", instead of just pushing out the payments with even more borrowed money, some may call it begging. I want to make it clear that at least one pool miner would want to do this and thinks that others should know what's going on before their mined BTC keeps rolling in like normal. |
