Moi plus j'y pense et plus je me dis que le seul service réellement indispensable, c'est le change de devises.
Il n'y a à mon avis aucune chance que bitcoin soit adopté par le grand public et par les entreprises avant longtemps. Peut-être même jamais, car une comptabilité en bitcoins est trop facile à masquer ou à protéger du fisc. Les entreprises doivent rendre des comptes à l'Etat et donc je doute que l'état les laisse utiliser une telle monnaie.
Mais en réalité cela n'a que peu d'importance. L'essentiel est qu'il soit facile de convertir ses bitcoins en devise nationale. Une telle convertibilité peut être assuré par un marché des changes performant, et dès lors qu'une telle convertibilité existe, alors on peut entrer dans n'importe quel magasin et acheter ce qu'on veut avec des bitcoins.
Ca peut paraître artificiel mais finalement cela ne l'est pas tant que ça. Mais ça mérite plus de justifications. J'écrirai plus sur ce sujet ultérieurement.
En tout cas moi pour l'instant je me concentre sur l'écriture de mon projet de plateforme de change opensource.

Error trying to withdrawal bitcoin.
"Something went wrong... Problem server?
We've been notified about this issue and we'll take a look at it shortly."
+1 Unfortunately it seems that davout has kind of got lost interest in his website. He is very little responsive. |

The last hash is doubled.
Indeed. I thought I had tried that but I guess I did it wrong. Thanks. |

Here is the Merkle tree for block 95002, which had three transactions: "mrkl_tree":[
"4fa598026d9be1ca0c2bff1b531e566b7ea7f90b72e75fda0c1795bc2dfa375c",
"186640daf908156e2616790d7c816235b0c43f668c3c38351b348c08ca44d457",
"ef3928700309b4deceac9a992a19a7481b4e520cbc0b1ab74e2645eee39c8da0",
"688c53517f62f7a65c0e87519c18a4de98f2ccafbf389b269d0bb867f88d166a",
"01889506f7fe9210045f588361881e2d16a034a62bc48ebd7b6b0a3edeaf5a6d",
"74f3a7df861d6a58957b84a3e425a8cf57e1e2e3a3def046dd200baeb8714f00"
]
I rewrote the two bash functions: bigEndianHex2littleEndianHex() {
local s=''
while read -n 2 char
do s=$char$s
done
echo $s
}
bitcoinHash() {
bigEndianHex2littleEndianHex |
xxd -p -r |
openssl dgst -sha256 -binary |
openssl dgst -sha256 -binary |
xxd -p -c 80 |
bigEndianHex2littleEndianHex
}
The fourth entry of the Merkle tree is easy to reconstitute. It's obviously made out of the first two. bitcoinHash <<<"186640daf908156e2616790d7c816235b0c43f668c3c38351b348c08ca44d457 4fa598026d9be1ca0c2bff1b531e566b7ea7f90b72e75fda0c1795bc2dfa375c" But then, I don't know how to get the fith out of the third. |

Ever heard this quote?: "Give me control of a nations money supply, and I care not who makes it’s laws." - Mater Amschel Rothschild, founder of the Rothschild banking dynasty.
Do you really think they will ever willingly switch to BitCoins? Do you realize what their centrally planed monopoly of money really represents to them? Do you realize who is behind the monetary system that the USA functions under atm and to what great lenghts they went in 1910-1913 to establish it and to what great lengths they still go today in order of propping up their status quo?
That's why I'm talking about them trying to find "excuses". They obviously can't reject bitcoin by saying: "oh no we didn't promote this currency because it was a threat to our world domination scheme." So they'll just say: "we didn't know it existed". |

on se voit dimanche ceci dit ce serait sympa qu'il y ait du monde histoire de papoter un peu pck moi je ne connais pas encore grand chose au bitcoin  Ok je confirme réception des 150 BTC. Je choisirai l'endroit et je te le communiquerai par PM. Ceux qui veulent organiser une rencontre plus conviviale peuvent le faire bien sûr mais ça n'a pas à être liés aux transactions réelles. |

At some point the guys from governments and financial institutions will defend themselves from not having brought up bitcoin to the public, nor to have used such a technology in the financial system.
They will say something like: "We just didn't know this currency existed, so we tried our best with what we had at this moment."
But isn't it part of their job to get informed about new tehcnological developpments in their activity? How hard is it to check out Wikipedia about digital money and to follow a link about a decentralised currency?
Those people are supposed to be smart and to know a lot of stuffs. That why they get so much money, whether it comes from tax payer or B. Bernanke's helicopter. If they didn't know about bitcoin, they have absolutely no excuse.
PS:
They could have come up with a fair decentralised monetary system. Truth is: they didn't even try.

She's quite cute as well: it's nice to see that bitcoin doesn't get some interest only from ugly geek dudes like myself. |

moi ca me convient Ok je te PM une adresse bitcoin. Tu peux payer maintenant ou dimanche une fois sur place. C'est comme tu veux, mais plus tu paies tôt plus tu évites le risque que quelqu'un surenchérisse. Car si quelqu'un propose plus de 150 btc avant dimanche, c'est à lui que reviendront les 100 euros. |

The same stuff but a bit smaller and smoother:  PS. I think it worths adding a bitcoin address in case someone would like to donate to reward this work: 15qwmFseu1r4K4ZByWiN5JB2xSLXXCMPfr PS#2. I suck at licensing stuffs but I'd like to allow people to use it without too many restrictions. I guess all I have to do is to say that I've made this with blender, ImageMagick, Gimp and the bitcoin logo we can see on Wikipedia. I publish this under the terms of the Attribution 3.0 Unported creative commons license.  I hope it's fine. |

moi j'ai 150 bitcoins que je veux revendre à tout prix (au 2 sens du terme  ) Je t'offre 100 euros pour tes 150 bitcoins, soit un cours de 0.6667 btc/eur. Si quelqu'un peut et veut céder plus de bitcoins pour ces mêmes 100 euros, qu'il se manifeste. |

Our only goal with this video is to spread Bitcoin and make people interested. Technical information is only included insofar as it helps that goal. As bytemaster says, we need one video to bring new users into the fold and a different one to explain the technology in depth. This one will be the former. I don't want to exclude the possibility that we will work on the latter afterwards. Sure, but I kind of hope that there is a way to describe how bitcoin works without being too technical. Maybe not technical at all. I was thinking of describing bitcoin by replacing computers by a book. As I see it, we woudl say that all the accounts are numbers written in a public large accounting book. Everyone can read it at any time. The only thing is that it is not easy to write in it. And it's a good thing: if we could all write in the book in the same time, it would be a mess. So we need a way to make it difficult. So there is some kind of a magic pen (a cryptographic pen). To obtain the pen, you must solve a difficult mathematic problem. And you can only write something that makes sense, otherwise people will immediately see the fraud and ignore what you wrote. I say this because if we just say what bitcoin is without trying to explain how it works, people will just don't believe it. I mean: sure, people would be glad to have a decentralised, taxation free money and stuffs. But without any explanation about how it is possible, they'll obviously be suspicious. I would if I hadn't read Satoshi's paper. |

When will the video be released? We don't have an exact date, but I will post a status update on Tuesday. Feel free to ask questions if you have any!
What is your script? I mean: do you try to explain how bitcoin works (double spending, hashes, blocks...), or do you just describe what bitcoin is (bitcoin address, currency/vs paiement method, P2P)? |

markm I wish your post made sense to me but I have no fking clue what you're on about.
I gave up trying to understand him long time ago. |

Finally I made it 160x160. For some reason I can't manage to prevent the frames from stacking up. PS. Ok I get it but I have to regenerate. Wait a sec... PS#2. Ok, here it is:  Pretty neat, isn't it? Here is the blender file, for those who are interested: http://s0.barwen.ch/~grondilu/bitcoin-flag.blend |

$ openssl dgst -sha256 -hex <<< "hello, world"

Cheers, different version of openssl I guess. $ openssl version OpenSSL 1.0.0c 2 Dec 2010 |

Can you render it with flagpole as gif image with transparent background?
Sure, let me try. I'll remove the sky and I'll set dimensions to 160x90 I'm not very happy with the lightning either (too many shadows). I'll try something else. |

But you have to get rid of the annoying 'std(...)= ':
Huh? I don't get you… Well, when I run openssl dgst -sha1 -hex <<<"hello, world", I get an annoying: (stdin)= cd50d19784897085a8d0e3e413f8612b097c03f1 I wish there was an option not to display this "(...)= " before my result. Anyway that's why I had to add a 'sed "s/^.* //"'. |

They're going to fight BitCoins with teeth and nails so the best thing we can do is to just ignore them because they are irrelevant
