I don't even think there'll be competitors. It's a digital commodity, not a company and not an app. Supernormal profits will bring participants to bitccoin, not to compete with it. It's not like you can invent a decentralised un-controlled competitor to bitcoin and then somehow make a profit from going up against the established open-sourced alternative.
Good point. |

Auction has ended.
Brocktice wins the auction with 1270 BTC.

25 blocks before the end.
Brocktice still leads at 1270 BTC.
Anyone at 1280 ?
It seems there is not much interest for this auction anymore, so I won't end this one on IRC unless someone outbids brocktice.

Maybe something like import-export secret keys? It would be convenient to keep piece of money outside of wallet.dat. Also this key output in the non ascii-armored format can be printed into the barcode and cached on paper. -----BEGIN BITCOIN ADDRESS PRIVATE KEY BLOCK-----
Address: 1cuh4378ry8743yr87yf87tf87wtf
Version: Bitcoin 0.3.21 (GNU/Linux)

-----END BITCOIN ADDRESS PRIVATE KEY BLOCK-----
I actually only need an "export" feature. I also don't think we need a special bitcoin header. We can stick to the header openssl use. I actually want to, for I want to use openssl with this key. so the format should be : -----BEGIN EC PARAMETERS----- BgUrgQQACg== -----END EC PARAMETERS----- -----BEGIN EC PRIVATE KEY----- MHQCAQEEII84GK/wX8stbmJWYL/WUM1nPAK1miIBDBeyNuo2vyf4oAcGBSuBBAAK oUQDQgAE/yRZIKrOj4GBfLFtMYuocJ5QF1Tr9rWMh2ixCyfodDWRWTIU21v3ehDR NJiAXHKwkhDqQ//i46NHoNUhjvx/lw== -----END EC PRIVATE KEY----- (I got this output from "openssl ecparam -out key.pem -name secp256k1 -genkey") The bitcoin address should be built from this file using an other program. |

If the address is a hash of the true public key, how are transactions verified? The sender attaches the public key of all output addresses to the transaction?
If so, if an address has ever been used to send any coins, it should be possible to retrieve its public key from the chain...
Anyway there must be a way to get the public key, since after all the bitcoin program uses it to verify transactions. But I confess I have to get a better understanding of the whole key signing process. |

I don't really see how to get a public key from it's hash.
Hum, right. My bad. Ahh I have to think this more thorously. PS. I've edited the original post in accordance. |

*** EDIT: Bounty has ended. Program was written. ***
I give 100 BTC to whoever can make the following program :
The program takes a bitcoin address on command line.
If the bitcoin address is not one of in the user's wallet, then the program does nothing apart from returning an error code.
If the bitcoin address is one of the user's wallet, then the program ouputs the corresponding Private key in PEM format, so it can be used by openssl.
That's all. 100 BTC.

gpg is standard. everyone uses it.
Pfffft, speak for yourself. I had yet to meet someone I know, in person or online that uses GPG or any kind of email encryption/privacy software. By everyone I think genjix meant "everyone who is using encryption for their personnal messages". Personnally I don't know any other encryption/signing software. |

So, if future is impractical to buy...then somebody could make a load of money by opening up a bitcoin future market and making it so easy to do so.
When bitcoin becomes world famous, then international finance is gonna get wild. It will be fun. But right now nobody has enough reputation to make it come true. But it will happen, I'm sure of it. |

But they never actually DO anything. If you care so deeply about keeping your petrol costs stable for the next 10 years I am sure it's not hard to find some financier who will offer you a hedge. But people just moan instead and demand that government does it for them.
or perhaps buying petrol futures is too impractical for joe average?
Very true. Some financial instruments could easily be used by people. I'm not sure about futures, but I know warrants are very easy to buy. |

Ok - thanks for the BSD sample output. How about this code then: #!/bin/sh
# Display foreign IP addresses coming from port 8333 --or-- connected to local port 8333.
# Append line at end with date and count of addresses displayed.
#
# GNU Linux netstat separates port numbers from IP addrs using colon ':',
# whereas BSD netstat separates them using a period '.'. The sed line
# below converts the BSD '.' to a ':', to make it easier for awk to
# split off the port.
netstat -an |
sed 's/\([0-9][0-9]*\.[0-9][0-9]*\.[0-9][0-9]*\.[0-9][0-9]*\)\.\([0-9][0-9]*\)/\1:\2/g' |
awk -v date="$(date)" '
$6 == "ESTABLISHED" && /:8333/ { split($5, a, ":"); print a[1] ; n++ }
END { print "# " date " : " n " bitcoin clients seen." }
'
omg your regex is ugly. sed -r 's/([0-9]+\.[0-9]+\.[0-9]+\.[0-9]+)\.([0-9]+)/\1:\2/g' |
And I'm pretty sure there is better. |

As it is the Bitcoin system is effectively DigitalCoin anyway when companies can trade their shares for it, their shares (CC) will have a certain value against bitcoins (PC). Maybe one day people will make bit-shares that involve some sort of digital signing and that can be handled as easily as bitcoins...
Yeah I've already been advocating for that on this forum. I just hope I will live long enough to see this happen. It would revolutionize capitalism. |

All current montetary politics is a joke.
Basically it consists in adjusting money supply (via interest rates) in order to maintain a relative price stability. But why would we want price stability ? Theoretically it's because it's difficult to have economic activity without it. How to pay wages if the value of money varies from one month to an other ? How to sign a long term contract if we have no way to know exactly what 100 monetary units will be able to buy next year ? This is the whole idea behind current economics and monetary policy. And this is bullshit.
Prices are not something that have to be decided by anyone. An apple is an apple, and there is no reason why it should cost more next year than right now. That's what some people think. But what if the production techniques have been improved ? What if suddenly less people like to eat apples ? Or if an other fruit gets invented (why not ?).
They say that when there is economic growth, we should increase the money supply in accordance, so that prices remain stable. But if bankers increase money supply to counter production improvement, isn't that a theft of consummers, who otherwise would have benefited from this improvement of productivity ? Isn't that also a theft of the producer, whose products gets to be at the same price although he had increased his productivity ?
Who on earth are those guys who get to decide what should be the price of the things we produce and consume ?
It's tough to pay wages in deflation. True. But sometimes the market wants it. The labour of someone may have some value at a certain time, but the same labour can have a different value a few months later. Some things can have happened. A machine can have been invented that does the same work. Other workers can have come up with more motivation to work, or better skills. Price stability has no reason to be prefered if it does not reflect economic reality.

What happens if Warren Buffet suddenly sells all his assets and burn all the corresponding money ? Won't that significantly increase the value of USD ? Basically someone who burns money is someone who decides to work for other human beings for free. There is nothing to do appart from thanking him.  |

On a larger scale (say, a construction firm ordering from a steel manufacturer), using CCs would even become an imperative, since they would otherwise incur potentially thousands of dollars in "losses".
Well, yes, I forgot about this credit aspect. So basically CCs are a generalised form of credit. When someone needs to borrow money, he would issue CCs, instead of going to a bank. Or, in other words, everyone is his own bank (when seeing a bank as a company offering credit, not a place where people store their money). So somehow credit coin would be to credit what bitcoin is to money. It has the merit of clarifying things. |

No offense, but I think Paul Grignon's ideas are just reinventing the wheel.
CC is just privatly issued currency. It's a good thing, but nothing new under the sun.
As you pointed out, his PC concept is kind of nebulous. Indeed BTC would make a clearer PC.
Anyway, I think that in such a ystem, PC will tend to have a far bigger importance than CC, so that CC will be quite anecdotic compared to PC.

At least it would be trivial to have small CL tools to perform bitcoin operations in this system, such as tools to import and export transactions, blocks and keypairs to/from normal files. *nix CL shells, such as Bash, are centered around the manipulation of data streams as files, and it's an incredibly powerful model.
Exactly. I also wonder if all communications could not be done using HTTP. Blocks would be published via http GET method (giving the hash of the preceding block), and transactions could be sent via POST method. One advantage of using http would be that it would be very hard for governments to forbid. |

lol if it was that easy to transfer money, we wouldn't need bitcoin at all |
