you should charge 1 btc per bid, whether it wins or not I doubt it would change anything. It would not discourage dishonnest bidders, while annoying the honnest ones. Imo.

I was directed here by someone asking questions about the darts game and after looking it over I have adjusted the game to calculate the winning hash ahead of time (in the same random fashion as before) and along with the address to send the bet to it will show the hash of the winning hash for that transaction, so that after the transaction is complete and the winning hash is revealed you can (if you want to, no extra requirements to play) check that it matches.
Still doesn't necessarily give any verification of the randomness of the hashes generated, but should be enough to show that the outcome isn't dependent on the size of the bet without revealing bet sizes in the history.
I'll try that, thks. Indeed if you don't show the hash before the player bets, there's nothing preventing you from chosing a losing outcome after the player has bet. Edit. I've tried again, and I still don't understand. Sure, it gives me a hash before I send money. But that doesn't prove anything. It doesn't even tell what hash function has been used. It doesn't prevent you from chosing the lose/win ratio you want. Edit #2. Here is what I suggest. First, you chose a random string and you keep it secret for now. Let's call it $s You then show the sha256sum of this string. Then you ask the player for an integer $n. Once the player has given you this number, you can show him $s, and everything that you will do next doesn't have to be secret. You compute n successive hashes of $s. You have to use a different hashfunction that the one used previously, otherwise the player could chose $n in order to obtain a winning outcome. So let's use sha224 here instead of sha256. $ f() { sha224sum <<< "$1" |cut -d' ' -f1; } $ while ((n--)); do h=$(f "$h"); done
Once this is done, you compute two more hashes, and you build your two coordinates with them : $ x=$(f h); y=$(f x) $ x=0.${x//[a-f]/} $ y=0.${y//[a-f]/}
Finally you can use those coordinates for your dart game.

What's the best way to invest? Wall St won't tell you the secret, but here it is: don't. Find a good money market fund as your base, and clip coupons by building a high quality relatively short duration bond ladder. It's essentially risk free, and it has beaten the market for over a decade now. Sleep well, save well, focus on your career, and enjoy your life -- and though you may not believe me, I guarantee you'll beat 95% of all investors in the long run, and you won't have to pay any "advisors" a nickel.
As far as I'm concerned, I prefer the "buy and hold" strategy, plus a strict diversification discipline. Never sell, and buy a lot of things : shareholdings, commodities, precious metals. If you are really wealthy, you can also buy things that cost a lot : real estate, art and other stuffs. Avoid monetary funds, government bonds and anything which is assimilated to cash. Buy what money can buy, don't keep money for itself.

FreeMoney leads at 1,200 BTC

Yes but bitcoin is at an all time high too!
Ahh, please don't try to ruin my business Still, 1,500 BTC or even 2,000 BTC wouldn't be outrageous.

Gold is almost at 1,400$/once right now. You still have a few blocks left to have a chance to get 5g of gold for 1,200 BTC only !
Don't delay too much before you send me your bid.
Edit. Also, let me remind you that according to bitcoinwatch.com, one gram of gold worth 478$. That means that 1,200$ for one gram is about 50% below the official price ! Go for it !

I don't know if it's bad or not. That's not the point, imo.
Is a storm a good thing ? Is the wind a bad thing ?
Whether deflation is a good or bad thing, when market forces want it, it has to happen. The government should not interfere to prevent deflation. It can only make things worse.

So far, Loki leads with 1,100 BTC.
Don't wait the last minute to make your bid !

I confess I am a bit disappointed with the number of orders I got. Only one, to tell you the truth.
Is 10 BTC still too expansive ?? Or do you just don't like Linux enough ?
Please tell me what you think about my offer.

I made my first short selling earning a total somewhere around 14 bitcoins. Booya.
Recommend nanotube as the to-go guy for your first short selling loan.
I'm not sure you should be proud of that but somehow I think it is good that this kind of thing is possible. It gives liquidity to the market. Plus, it's fun. Although I would not do this kind of thing, I won't blame you.

Common sense doesn't come cheap, and that little pair of words has very different semantics value for different people. I don't know anything about Austrian economics, so I didn't find it funny nor offensive.
I'd like to say that I personnaly adhere to austrian economics school, and yet I've found this joke very funny.

I suggest trying to build a dyson sphere that absorb the entire energy of the sun instead. With the dyson sphere, we'll build more and more desirable space to live using the entire resources of the solar system.
So we'll have to master interstellar travel because we don't have enough matter in our own solar system to build a dyson sphere. Should I bother googling "Dyson Sphere" ? Or can I just ignore that ?

Will you guys please start talking in English? Basically genjix is talking about how important it is for human kind to explore solar system. I'm telling him that it is just some technocratic propaganda, and it should not be founded using taxation. I also told him that the moon and Mars are nothing but giant desertic places. And nobody wants to live in a desertic land. Going to Mars and trying to live there is about as weird as going to the south pole and establishing a permanent camp there.

BTW, those of you who assume that others whom you interact with on an Internet forum think like yourselves, should try to remember that it's is highly likely that you are being offensive to the very people that you are trying to amuse.
I don't understand this paragraph. But I guess trying to be humoristic on Internet is even harder than I thought.

As soon as we have multiple implementations the trust that we have to put into the developers of any of those clients is reduced,...
Any progress in that direction ? I red somewhere that some people wanted to work on a Python implementation of the protocol.

The way I see it, there needs to be some sort of "official" or consensus set of parameters and rules that a block chain needs to obey.
Otherwise, if the only requirement for acceptance was chain length, someone could just arbitrarily change the rules, say, that 1000 coins are awarded instead of 50 every time a block is solved.
Right now, this "official" set of rules comes from satoshi, and you are quite right, if he changed the source code to his own personal advantage (and to the disadvantage of other users), he could probably manage to rip off a few people, simply because this is a very early stage in this project and most people automatically download from sourceforge as soon as a new version is realeased.
But that would be a one-off. People would no longer trust either satoshi or sourceforge, and some other consensus would soon emerge. After that, satoshi couldn't change the rules even if he wanted to.
I think that's pretty much the same for any free software. At some point, there is someone who is responsible from signing an official release, and people must have some confidence in this person. I mean, everything that tentative is saying could be said about SSL, for instance. And SSL is the root of current security on internet, isn't it ? We could also say that about Linus Torwalds towards the linux kernel. Maybe someday Linus will modify the kernel and put a troyan horse in it. It would be a one shot scam, as everybody will soon find out and he won't be trusted anymore. We will put our confidence in someone else.

Maybe one day gold will be backed by bitcoins. haha that would make the Austrian economists heads spin around. LOL !

Maybe it still has to have 50%+1 processing power or force people to use its own client which would be quite hard. At most kill the businesses that sell products for bitcoins. Then we still have TOR. Its a really tit for tat fight cat and mouse between who will be able to control or undermine who.
Fair enough. I laugh when people say bitcoin should be backed by metal when metal is easily confiscated.... I prefer my currency backed by cryptography. Maybe one day gold will be backed by bitcoins.
