The bitcoin client will tell you the answer to this if you ask it for help: > bitcoin-qt -?... -rpcport=<port> Listen for JSON-RPC connections on <port> (default: 8332 or testnet: 18332) It is true that the default RPC port change is not listed as one of the testnet changes on the Wiki. This option is in most people's bitcoin.conf file so it does not change when selecting testnet. |

That guy's a real asshole... or else a lot of people just sent him tons of BTC... idk for sure.
Anyway, as a not-so-expert-when-it-comes-to-security-guy, how should a firewall be configured on a bitcoin-only machine?
To allow Bitcoin through the firewall. The original poster's problem was that he created a bitcoin configuration file specifically turning on the RPC remote control of Bitcoin (default off), setting an extremely simple user/password combination (default disabled), and adding an option to allow worldwide IP access (default local machine only). It would be the equivalent of leaving the keys in the ignition, leaving the car running, putting the signed-over vehicle title in the window, and posting a sign that said "free car". |

Instead, the currency is run by computer code that distributes new bitcoins at a set rate to people who devote web servers to keep the code running. The bitcoins are then bought and sold for regular U.S. dollars online.
That's actually surprisingly close. How far we've come. All these new media stories sound positive. Web servers? Running Apache mod_bitcoin, I'm sure... |

The db.log or debug.log may have information about what errors are happening when the wallet is being accessed. A preliminary recovery option is to run Bitcoin with the command-line option -salvagewallet. |

Unable to find a definitive answer to the question of copying the blockchain to another computer, I asked Gavin via email:
In Bitcoin-Qt 0.8+, how can the blockchain be copied from one computer to another? Is it simply a matter of copying the blocks and chainstate directories?
His reply:
Yes
That is appropriately curt. You feel entitled to bother a lead developer for your own personal tech support? I have a feeling this is one reason why Satoshi was no longer entertained with the forum. |

|

No. Currency exchanges are independent businesses. It is as legitimate to add "$200 at deepceleron's exchange" or "10 socks per bitcoin" as any other exchange's rate. |

Where do you get information that the port is outdated? extern bool fTestNet;
static inline unsigned short GetDefaultPort(const bool testnet = fTestNet)
{
return testnet ? 18333 : 8333;
}
If you need some test coins, just put up your address. Or importprivkey cMiCLUK7Hx9hviPdfPw4GTxfqao1TTDw43jmgmmRv2TENSw9cFrw (for the OP only) |

This error message comes from the miner kernel (the software that runs on your video card) returning a block hash that upon a double-check before sending is not a valid block hash. If it is happening all the time, there is a compatibility problem with the different versions of software/driver/hardware that you have installed. If this is a mine-only machine using HD 5xxx-HD6xxx hardware, I would recommend using the ATI driver package 11.11 with it's included OpenCL (you must first manually remove the current driver and remove some files manually that aren't removed by the install). Then CGMiner or Phoenix software instead of GUIMiner, plus underclock your GPU memory to 300MHz. |

Do not look at blockchain.info or other block explorer websites to determine information about your wallet balance. You have many addresses in your wallet, some hidden from you, that together contribute to your balance. It is a feature that nobody on the Bitcoin network can reliably determine all the addresses that are yours.
You may have an amount removed from your wallet balance if you have transmitted any transactions which are not confirmed. I don't know why you are having problems dumping a key other than the address is not yours, I just confirmed that even unused reserve address keys can be dumped.

A blockchain torrent was exactly what i was thinking.
A humble suggestion:
Maybe a brand new install of bitcoin-qt should alert the user that there are other, faster options for a blockchain download (if it's not going to automatically take advantage of those faster options itself).
There's actually no guarantee that it will be faster. The main restriction to initial download speed is CPU processing, and with the torrent, you are delaying the begin of CPU work until the torrent is complete. |

You will likely transmit with high priority and not require a fee, example if you have just 10 testcoins and wait 15 blocks it will be free, unless one or more of your outputs is less than 0.01, triggering fee-always anti-spam rules. The 27kB free space always will have space unless someone is doing something wacky while you are sending.
The difficulty is only 11 if you want to mine your own blocks to include free tx.

Considering that the blockchain is 85% spam from one site, the fee isn't doing a good enough job. Go to any of those money transfer places and ask how much it costs to wire money to your relatives in another country - the answer is a bit more than $0.04 USD.

Your session has timed out? Maybe this link would be more useful. Don't worry, it won't hold up. Federal courts have repeatedly ruled that generic terms can't become trademarks. If this Michael is as wise as the last one, he'll abandon it too, and do so before opposition proceedings start. See my post above, this must be challenged within 30 days.

And where can I verify/see this? On the blockchain?
Did Satoshi release/open source Bitcoin publicly on the same day that mining began? Or was it some time later?
Where did he make the announcement/initial release?
As proof that the blockchain was not pre-mined, the manually created genesis block included a January 3 2009 headline from the Times UK: " Chancellor Alistair Darling on brink of second bailout for banks". The release announcement was on January 9 2009: http://www.metzdowd.com/pipermail/cryptography/2009-January/014994.html: Announcing the first release of Bitcoin, a new electronic cash system that uses a peer-to-peer network to prevent double-spending. It's completely decentralized with no server or central authority. See bitcoin.org for screenshots. Download link: http://downloads.sourceforge.net/bitcoin/bitcoin-0.1.0.rarWindows only for now. Open source C++ code is included. - Unpack the files into a directory - Run BITCOIN.EXE - It automatically connects to other nodes... Then we see from the timestamps of the blockchain that mining started after the release announcement. 1: "time" : 1231469665, Fri, 09 Jan 2009 02:54:25 GMT 2: "time" : 1231469744, Fri, 09 Jan 2009 02:55:44 GMT 3: "time" : 1231470173, Fri, 09 Jan 2009 03:02:53 GMT 4: "time" : 1231470988, Fri, 09 Jan 2009 03:16:28 GMT 5: "time" : 1231471428, Fri, 09 Jan 2009 03:23:48 GMT 6: "time" : 1231471789, Fri, 09 Jan 2009 03:29:49 GMT 7: "time" : 1231472369, Fri, 09 Jan 2009 03:39:29 GMT 8: "time" : 1231472743, Fri, 09 Jan 2009 03:45:43 GMT 9: "time" : 1231473279, Fri, 09 Jan 2009 03:54:39 GMT It's probable that the time between Jan 3 - Jan 9 was testing, likely including several days of discarded blockchain mining before Satoshi decided to release.
The code wasn't easily compiled and built, there was nearly no documentation, etc.

Intro
-----
Bitcoin is an electronic cash system that uses a peer-to-peer network to
prevent double-spending. It's completely decentralized with no server or
central authority.
Operating Systems
-----------------
Windows NT/2000/XP (and probably Vista)
Vista hasn't been tested yet. All the libraries used are cross-platform, so
there's nothing preventing future Linux and Mac builds.
Setup
-----
Unpack the files into a directory and run bitcoin.exe.
The software automatically finds other nodes to connect to. You should set
your firewall to forward port 8333 to your computer so you can receive incoming
connections, otherwise the nodes you can connect with will be limited.
To support the network by running a node, select:
Options->Generate Coins
and keep the program open or minimized. It runs at idle priority when no other
programs are using the CPU. Your computer will be solving a very difficult
computational problem that is used to lock in blocks of transactions. The time
to generate a block varies each time, but may take days or months, depending
on the speed of your computer and the competition on the network. It's not a
computation that has to start over from the beginning if you stop and restart
it. A solution might be found at any given moment it's running. As a reward
for supporting the network, you receive coins when you successfully generate a
block. |

Please note that the shape of an object can affect the conductivity, so a conductivity test isn't a good way to test for purity. I had been wondering about that and indeed couldn't think of a way around that, except for actually having a numerical simulation program in which you fill in the details, and which then simulates the resistance. Then you still have to account for contact point resistance, which you might do by measuring different points on the coin (edge to opposite side edge, middle of face to middle of flipside face, edge to face, etc) and then correcting for the constant factor. You'd also be dealing with measuring a coin who's conductivity is ten times higher than even the multimeter test leads. On page 10 is a subject called "milliohmmeter" discussing circuits and methodology to measure such low resistances: http://cds.linear.com/docs/en/application-note/an98f.pdfSince silver is the best conductor in the world at temperatures ~293K, what you'd be looking for is any resistance higher than a known good reference coin of the same minting. To establish what an expected resistance is, I'm not aware of what software can model electrical resistance @ current vs skin effects etc on various shapes, such a project would likely be PhD-earning material. |

You should be creating a whole bunch of addresses in your wallet anyway, one to give every person that is going to send you a payment at least, if not one for every payment you will get. You can just re-label the address for future use.

Satoshidice sent you 0 confirmation coins that never confirmed and you spent them. You should remove all unconfirmed transactions from your wallet with pywallet.py -web and then restart bitcoin-qt -rescan to see if there is any balance restored to your wallet. If you feel like gambling in the future, send money to the address in my signature and I'll bet you the same amount that you send that I won't send it back. |
