It seems to be quite an intense debate about bitcoin on quora.com. I've noticed a great quote from a guy named J.C. Hewitt: That being said, I think that Bitcoin may wind up thriving. The ideological impetus behind it is admirable. The technological achievement is impressive. I like that it was motivated by science fiction, like most great technologies. I think that it should be free to compete with other currencies.

To me this DSK affair is a shame for my country. Especially since french medias knew about his perverted behaviors, but they didn't talk about it, pretexting it was his "private life".
I'm ashamed to be french, honnestly.

I like it.
It's tough to make a national radio ad about bitcoin without making it sound like some scam/commercial stuff. I think you managed to make something that's clear about what bitcoin is. I would have liked to hear it's open source software, though.

If bitcoin is ever made illegal worldwide, I'll just hope international organized crime will have already started to use it and offer a shadow exchange service.

Ton idée me parait difficile à mettre en pratique.
Limiter le hash à une épreuve d'une trentaine de secondes toutes les dix minutes, c'est peut-être faisable techniquement (et encore je vois mal comment), mais de toute façon cela nécessiterait une difficulté bien plus grande (en gros d'un facteur 10*60/30= 20) pour garder un taux de forks comparable. Donc ça s'oppose au but initial qui est de réduire la consommation d'énergie.
Au bout de 30s chaque mineur envoi son meilleur hash sur le réseau, il n'y a plus de notion de difficulté à atteindre. Chaque noeud reçoit ces hashs et les accepte ou pas s'ils arrivent après un certain délai (tout comme les blocks bitcoin qui contiennent un timestamp). Pour limiter le temps de l'épreuve, il faut que les données nécessaires à celle-ci soient connues juste avant le début de l'épreuve, et c'est ce à quoi sert le hash du block précédent (tout comme bitcoin, à la différence qu'ici on sait quand il va arriver). L'acceptation d'un block ne peut pas dépendre de la perception qu'en a un noeud. Car sinon on remplace une course à la puissance par une course aux noeuds (cf. plus haut). Je ne sais pas très bien comment est géré le timestamp en unité temporelles normales. Je sais en gros que c'est une moyenne constatées sur les noeuds environnants, mais je sais surtout que ce n'est pas trop ce qui compte dans l'acceptation d'un block. Le timestamp qui compte c'est celui qui est exprimé en unités temporelles machines, c'est à dire le hash lui-même. Si tu te fies à un timestamp conventionnel, alors il suffit de posséder suffisamment de noeuds sur le réseau pour mentir sur ton temps machine.

En rendant le système inactif 90% du temps, vous offririez du temps aux attaquants. Ils pourraient l'utiliser pour donner du poids à des blocs dans lesquels leurs propres transactions ont été modifiées (double dépense).
Bien vu. Ça m'avait échappé.

@bruce: There is not much to discuss, really. I tried to release it on CC-BY license, but maybe I should have tried to publish it on public domain.
It's not a big deal, just do whatever you want with this file. You can also search "blender flag" on google video. You'll see it's quite easy to do it yourself.

I wonder if there could be a way to create a shadow market exchange.
Basically it would be like MtGox, but instead of explicitely trading bitcoins, we would trade some other digital stuffs, such as images. The bitcoin transfers would still occur but in an hidden way.
If some customers get "caught", others could just deny having done the same thing.

Just curious: does anyone still have the bitcoin address so I can have a look and see if he spent his bitcoins?

Oh my god, how stupid is that!?? What's the point of having a debt ceiling if congress keeps increasing it each time it is reached? It's a joke, right?

Well, I guess it was really a black hole, as this guy probably lost interest in bitcoin and dropped his wallet. Too bad for him, imho.

There is every reason to kill them. They are all useless and unnecessarily consuming resources of this planet
And people wonder why readers of this forum often dismiss BitCoin entirely. This is one post out of 120729. On every forum at some point some people cross lines. Moreover, you're a moderator. Feel free to moderate him.

A Bitcoin tax will however have to be implemented in the client - and more than 50% of Bitcoin client users will have to democratically elect to the use of this client - all in the spirit of Bitcoin.
I think it's rather 50% of bitcoin processing power, which is quite different. Basically this client would reject all transactions that don't include a fee to some particular address belonging to the government. Neat idea.

To be fair, their job was useful before bitcoin came out. What was not acceptable was only the fact that they used government to enforce their monopoly on this economic sector.

I answered 'Totally'
Somehow I wonder if I'll ever manage to free my mind from this whole project.

God damn it I'm still waiting for some funds to be received by MtGox. Bloody bank wire delays....

Also, if you cut out all ways to buy bitcoins using the banking system, you have an absolute huge effect on the economy.
It will happen soon or later. They'll have MtGox and other currency exchange closed. However, I'm pretty sure that won't destroy the bitcoin economy. But only time will tell.

Sounds more like praise than fear.
[ Author uncloaking here ] Yes. It's praise. I am a technotarian--and in fact the creator of the word (I think). I'm a huge fan of bitcoin and hope that it take hold. Hi Jason, I've just realised that you are quite a famous and successful IT entrepreneur. Welcome on this forum. http://en.wikipedia.org/wiki/Jason_Calacanis
