I can't believe this has not been done already. I had no idea the risk of collision could be that low with just four english words.

You say get rid.. i say invest.
Whenever you invest into something that is not FED notes or USD-denominated bonds, you get rid of your dollars. It's as simple as that and it is not just rhetoric. |

There will always be people like me who will always be reluctant to accept any currency for which we don't even know what is the total amount in existence.
The greater fool is the one who accepts to keep such a currency for any significative amount of time. So unless you are poor and thus have no savings whatsoever, you want to keep stuff that are not constantly devaluated. Bitcoin is undoubtly one of these stuff.
What you are saying borders on the far fringe. It is quite dramatic. The us dollar will be around a lot longer then we will be alive. Anyone with money invests it and hopes to exceed the inflation rate. Say 10% per year as a fine goal. They diversify also. There are hedges one can use besides bitcoin that are many times more trusted. Gold, property, desirable objects, etc.. Bitcoin being one of them has yet to be proven. Time has to pass to show if that is true. For now it is rampant speculation. To consider it anything else just demonstrates you have blinders on, very naive, or have drank the koolaid from jamestown. I am here.. So i also see something in bitcoin. I just do not preach the gospel according to satoshi. It has possibilities but it has a very very long ways to go. Before bitcoin, I bought some gold because I did not trust the national currency for holding any value. It was not just because of the long history of gold as a storage for value (after all, it's easy to notice how the price of gold had a slow but very real decrease from the 80s to the end of the 90s). If I bought some gold, it's because I knew that at least, it's not something central banks can print like crazy. For bitcoin, it's the same. Indeed no-one can know if bitcoin will hold its economic value in the long term. You are totally right about that. But I don't need such an empiric argument. All I need is to run a version of the bitcoin software where the total amount of bitcoins is written in the code. One bitcoin will always be a twenty-one millionth of the total amount of bitcoins. That's what I mean when I say it can not be devaluated. It's a fact written in the code. It does not need the proof of time to be considered true. |

they still use that insane groupthink-o-matic comment karma system.
Makes me think of a word I learned today, in the last Vsauce vid: cyberbalkanization. Though I understand the need to avoid being overwhelmed by insignificant or silly comments, the karma system really sucks as it only makes you talk with people who think more or less like you. Kind of miss the point of talking with people. |

Why are there so many bitcoin haters on slashdot? I don't understand. Probably because they see it as a greater fool type setup. As long as there us a greater fool out there willing to buy your bitcoins the scheme continues. They tend to think this will eventually end. There will always be people like me who will always be reluctant to accept any currency for which we don't even know what is the total amount in existence. The greater fool is the one who accepts to keep such a currency for any significative amount of time. So unless you are poor and thus have no savings whatsoever, you want to keep stuff that are not constantly devaluated. Bitcoin is undoubtly one of these stuff. |

Tout d'abord merci grondilu pour ta réponse, +de 70 vues et une seule réponse  où est l'entraide (but d'un forum) Vendrais-tu des bitcoins ? Moi personnellement, non. À moins que tu sois disposé à payer sensiblement plus cher que le marché. Je te conseille Instawire. C'est d'une simplicité déconcertante. |

La vérité, que les économistes orthodoxes ne veulent pas énoncer, c'est que la création quasi illimitée de monnaie centrale par l'émission de dettes (par les banques privées), provoque une augmentation des prix de l'immobilier et des actions (les actifs que les banques achètent avec la monnaie centrale créée ex nihilo) alors que les salaires et les prestations sociales croissent très lentement. C'est quand même très caricatural, comme point de vue  Les banques n'achètent rien ou presque pour leur compte propre. Mais j'espère que t'as raison, ça fait cinq ans que j'attends que les banques centrales provoquent un rallie sur les marchés actions. Tu es naïf là mai stricto sensu tu as raison: les banques ont des filiales immobilières qui achètent l'immobilier avec les prêts que leur font leur maison mère. Je ne vois pas trop la différence à part un tour de passe passe comptable. Quand au marché des actions, il ne se maintient (voire progresse en 2012) que grâce à la création monétaire illimitée: ce ne sont pas les actions qui montent c'est la monnaie qui ne vaut plus rien. Sur les marchés, les plus gros intervenants sont les investisseurs institutionnels. Les banques (ou leurs filiales de placement et investissement) interviennent surtout en tant qu'intermédiaires (arbitrage, courtage, etc.). Certes, elles se font des tas de tunes au passage mais ça reste faible par rapport aux autres intervenants. Et cesse de parler de création monétaire "illimitée". Dis "abusive" ou "excessive" mais si tu dis "illimitée" comme ça t'es pas crédible. Il y a des limites. |

Guys, cumon  You are talking with highload architect and unix sysadmin Who doesn't believe that optimal search is log(n)  |

Plenty of data structures can look up individual transactions in O(log u) where u is the number of unspent transactions.
O(log u) - proof pls. No need for proof, it's common knowledge. Just look on the top right. |
|

Each trans can have many inputs. And every input needs to be found in huge data set.
And again, it is not a descending process. Even if your transaction has an hundred inputs, you'll have to verify that each of these input point to an output of a valid transaction, but you won't go further, for the same reason as described above. There is no exponential growth of the number of required checks. Also, the number of inputs and outputs is more or less proportional to the size of the transactions, or the average size of the block. I've already calculated that for 10k transaction par block it was about 8kB per second, iirc. However you look at it, processing 8kB of data per second does not seem like such a tough task for a computer. |

It's a cumulative graph and it looks quite linear. What looks linear in a cumulative graph? A constant! Also those are "destroyed" bitcoins. Therefore they represent transactions that could be "forgotten". So if this is of any relation with this thread (which is not obvious), it really does not seem to prove your point at all. |
|

Unspent needs to be verified against spent. And spent are growing to infinity.
It's not a descending process. Coinbase transaction A is spent by transaction B which is spent by transaction C. During database loading, you verify each block and you say: - ok A is good, - (you process more blocks) - oh B spends A so B is good and I can forget about A - (you keep processing more blocks) - oh C spends B so C is good and I can forget about B. Now if a transaction D comes and spends C you don't have to go all the way to A because you just need to remember that C is good. All you have to do is to put C (and not A nor B) in an index or something so that you don't have to do this everytime you run the client. PS. Of course I oversimplify here because there can be chain forking which requires that you don't forget spent transactions too easily. But even so, "forget" is a bit too strong a word since it just means you don't put it in RAM anymore. It's still on disk. |

I've never ever used binary newsgroups to download files. And yet I tried at least once, but I couldn't figure out how to use this thing. I've always used P2P.
Are binary newsgroups still used by lots of people nowadays?

Bonjour à tous. Je viens de connaitre BitCoin et j'avoue ne rien y comprendre  - Comment achete t'on des bitcoins via CB/PayPal ?
- Qu'est que c'est que cette histoire de Trading / Liberty Reserve... ?
- Qu'est ce que le mining ? On doit lancer un programme qui "mine" et ça nous donne de l'argent
Merci de répondre à ces questions car ce système est incomprehensible !! Salut, bon, un truc que tu dois comprendre d'abord: bitcoin est un système monétaire décentralisé. Donc il y a autant de moyens d'acheter ou de vendre des bitcoins qu'il y a des gens pour mettre en place ces moyens. Donc pour répondre à ta première question, pour acheter des bitcoins par CB ou Paypal, tu dois trouver quelqu'un qui est disposé à t'en vendre par cette méthode. Ça peut être un membre de ce forum dans le cas de Paypal, ou une société qui propose ce genre de service si tu veux payer par carte bancaire (la plus connue étant Instawire). Concernant ta deuxième question, essaie d'être plus précis car il est difficile de voir à quoi tu fais allusion exactement. Enfin, le mining est le processus par lequel les bitcoins sont créés initialement. 50 bitcoins ont été attribués toutes les dix minutes au cours des quatres dernières années. Le processus d'attribution est analogue à un tirage au sort dans lequel tes chances de gain sont proportionnelles à ta puissance de calcul. C'est ça qu'on appelle le minage, et de nos jours compte tenu de la concurrence entre les mineurs, c'est devenu très difficile avec un équipement électronique grand public. Depuis un mois environ la rétribution est passée à 25 bitcoins. Ça passera à 12.5 dans quatre ans, et ainsi de suite. |

When countries start using it out of necessity of foresight it still won't be a national currency, just like it isn't a drug or gambling or sock currency.
Being a national currency does not mean that the currency belongs to a nation. It just means that this nation officially uses this currency. Same as the english language is the official language in Great-Britain, and yet english is not only used by british people. |
