Aja eine interessante Frage gibts schon.... was passiert, wenn einfach so viele Transaktionen gleichzeitig sind (wenn mehr Leute Bitcoins benützen), dass die Clients nicht mehr hinterher kommen mit dem runterladen (aufgrund zu niedriger Bandbreite)...
Man könnte vielleicht eine Netzwerk-Simulation machen um zu sehen, wie gut bitcoin skaliert. Hier: https://en.bitcoin.it/wiki/Scalability ist von 2000 transaktionen pro Sekunde (bei visa) die Rede. Welche resourcen wären dafür notwendig (pro node, gesamt)? (in abhängigkeit von Netzwerkgrösse, vernetztheitsgrad,... ?). Wird bitcoin eher wie ehemals Gold verwendet werden - als Deckung für andere Währungen, so dass quasi nur die Banken bitcoin nodes haben und der Normalbürger die bitcoin-gedeckten Währungen als Zahlungsmittel verwendet (Banknoten)? |

Das System hinter Bitcoins wird seit 2007 von einer Hackergruppe entwickelt, die heute vom US-Bundesstaat Massachusetts aus operiert.

This. Is. Awesome. Except, f lat money?!  +1 awesome. Especially like the ending: Money is trust in the system, be it the earth, the government, or the internet. So our question to you is this: 'who do you trust?' |

The key issue is that the early adopters have nearly all of the cards.
They have (had?) 1/3 of the money. 2/3 are still up for grab by anyone. (counting anyone who joined before now to be an early adopter) Probably 1/3 of the 6 million that belonged to miners initially were sold to speculators and "normal" people wanting some bitcoins. |

This is being discussed in another thread. sorry, can't seem to find it. Could you point out the thread for me? |

Just thought I'd let people know that http://tradebitcoin.com is back in working condition. It's a google mashup you can use to find local bitcoin exchangers. I've been pegging the author for a while and he just got the problems fixed in 15 minutes . Should the map not show on first load, try shift-reloading. I know the "exchange crisis" is over for now, but as a last resort, having local people to meet and exchange local currency for bitcoins or vice-versa still seems important to me. I've entered myself a while back and 4 people contacted me via skype. I sold bitcoins to two of them. It was fun (meet at starbucks, send coins using ssh through starbucks wifi, cash on table). One cool thing (in my view) of trading "cash 4 cash" locally in real life is that it's compeletely invisible to outsiders, because both transactions are pseudonymous/anonymous to the outside and only the trading parties know of the exchange even happening. So, if you like, go ahead and enter your info on the site or find someone to trade with if you want to buy/sell some BTC. |

Looks like MtGox WebSockets broken after reopening - connection can be established but no data received.
Mark, are you going to fix it?
+1 also: I can't seem to be able to use the classic Trade API, either. Says something about a "bad token". Anyone know about that? |

Gerade in dieser Hinsicht habe ich mich auch schon gefragt: Wie sieht es eigentlich mit der Transparenz ein? Ist sowas überhaupt festzustellen? Wie weiss ich das ein Poolbetreiber nicht betrügt?
Eigentlich müsste man das im miner einbauen können: 1.) miner besorgt sich irgendwoher die "echte" difficulty 2.) bei gefundener nonce wird einfach geprüft, ob hash < "echte difficulty", falls ja: output "BLOCK found, please check if pool announced a block" falls nein: weiter wie bisher nicht wahr? |
|
|
|
nun da mach ich nem pool ja um einiges mehr omg, wozu sich das solo risiko antuen wenn ich 50 tage für 50 BTC brauche.
im pool mache ich täglich ja mehr als 1 BTC bei 2.5 g/Hash
Solo is cooler, pool sicherer. Faustregel: wenn "average time to find block" < "time until next difficulty increase" => mine solo In deinem Fall also: 50 days < 14 days => mine in pool (always) |

No one yet has answered this problem: Its too easy to get robbed. You send someone some bitcoins and they can just walk! It's just like posting cash to a stranger, totally stupid.
No-one posts cash to stranger, so no-one will send bitcoins! It's obvious!
In a face to face transaction, use cash - cus its anonymous.
In an internet transaction, use Paypal etc, cuz its the only way not to get robbed.
Add escrow to bitcoin and you've gained nothing now. The whole project is totally pointless!
Why can no-one give me a robust resolution. By robust, I mean not some juvenile, hand waving gibberish arguement.
You have a point. I think there will be payment systems on top of bitcoin some day (google, maybe even paypal, visa come to mind), which offer chargeback, fast hassle-free payment and protection from theft to a certain degree. Bitcoin is online gold, not many trade in gold nowadays, but it's used as store of value. Bitcoin might have similar fate with other currencies pegged to it. Not a "robust solution", but maybe a direction to think? |

No, last time I read the guy had it offline and backed up in multiple locations...
Still though if the value of btc crashes to 0 he's still screwed...
Not more screwed than the rest of us, though. Yep..I'm willing to bet some BTC that he already cashed out a decent chunk of that. Tis all wild speculation, but I salute him for managing to carry the torch till the end. What end? |

Hi,
I am considering building a dedicated mining rig and would like to know if a more powerful CPU has any effect on the hash rate performance vs. a less powerful one, ie. quad core vs dual core. If CPU selection has little effect then I can save some cash by purchasing a base CPU.
I will be installing an hd6990.
Thanks
I have a very cheap board that cost me €48 including CPU (via c7): asrock pv530, I think... no problems, saves lots of power |

P.P.S. weusecoins video finally got it's mainstream TV spot (even if just outtakes), congratulations.
your probably talking about "mainstream english-speaking TV", right, because otherwise: tagesschau is pretty mainstream maybe also the "czech CNN" piece (with slush in it) had outtakes of weusecoins, not sure: http://www.ct24.cz/vysilani/2011/06/05/211411058050022-20:00-horizont-ct24/ |

"long pieces of computer algorithms" has to be my favourite all time definition of bitcoins took me a while... they're talking about the blockchain! hilarious! |

well, counting 3 different mtgox-leak-related spam-emails up to now. this sux! In addition to the one already mentioned, I received: - We Accept Bitcoins - GBVault - this one has the recipient list in "To" header, damn moron!
- Was this the last straw with Mt Gox? - another tradehill referrer.
|
|
|

I think I've worked out who this person is who sent the emails. For obvious reasons I wont name and shame, but I must say that wether the intentions where good or bad. Not cool.
His intentions are clear: make money by referring people to tradehill. The other stuff about "letting everyone know" is bullshit, because mtgox already did that. This is very lowly behaviour. Shame on him. |

I was OK with one. But I got six of the same e-mail. If you're going to e-mail all the users in the leaked database like a badass 31337 Internet hero, do it properly.
One is not ok. 15 (which I got) is not ok at all. What the hell good is it to send it more than once??? |
