another argument pro aliases
And another reason not to use windows with valuable data... 300 million windows 7 users are not going to switch to linux. The windows bitcoin client should be hardened as much as possible against these kinds of attacks, because windows users are by far the largest demographic. We need them if bitcoin is to succeed. |

any ways what it did is when i copied the btc address from your site in a browser and pasted to my account on btc-e in another browser tab to request withdrawal it would paste a different address i didnt notice it till today it was in a link on bitcointalk.org for an optimized miner so i downloaded the miner and ran it nothing happened so i just ignored it and didnt think anything of it until now From the user. It's a new address each time. I believe that visually verifying the address will protect against this. The addresses so far: 17PPGjFhmvt75yPAd5yFv9iYyBGQfHevnd 14Yq1jKRqwbb9oExcyZFZ6a92QTk333WEZ Is it possible for malicious code to detect a <mousebutton-down> event on a send dialog box, then insert the hackers address a millisecond later? In such a case, visual verification may not thwart the attack. A 'lock address' function could help. The address locks the moment is it pasted into the field. No unlock (except cancel). |

I mean that sucks but on the other hand I got to say awesome to the malware writer. Get the user to send coins to the wrong address. No need to keylog, hack the client, look for wallet.dat, spoof RPC, etc. Just get the user to send you money.
I've been WONDERING when the first hacker would do this. Its so obvious. |

Physics is not the only problem. Economic motivators may well play a bigger role. Will the budgets for chip R&D always be sufficient to follow Moore's Law? What if there is a prolonged depression, or a materials shortage? Who knows what new exotic semiconductor raw materials will be required in the future.
Will there be adequate demand to finance ever increasingly powerful chips? We are already seeing lower demand for desktop PC's, and a shift to mobile devices with low-power, thermally efficient CPU's. If server farms/supercomputers need more power, they can just keep stacking the latest modular hardware.

Moore's law won't continue forever but certainly another 1 million fold increase is possible.
You were just pointing out that 1 million fold increase makes it "impossible". Of course someone in 1970 could have said the same thing.
I didn't say that. A 4040 CPU has 2700 transistors. To maintain this doubling every 18 months would require 2.7 BILLLIIIIIOOOOONN gates by 2010. Impossible I say.
You wake up every morning. That must mean you will wake up every morning for AT LEAST 150 more years. Right? The US dollar has been devalued approximately 95% in about a century. Will it continue devaluing into infinity, because after all, 'the future is like the past'? |

By your logic current chips are "impossible". Transistor density has increased by a factor of ~1 billion over the prior 40 years.
Note Moore's law holds that cost effective transistor density will double every 2 years. Not every 1.5 years ad indicated in your post and not every 1 year as indicated in the prior one.
Your logic doesn't follow. You argue that Moore's Law will continue because the future will be like the past. That is flawed logic. If the future is like the past for Moore's Law, you should expect the number of transistors on a chip to go to zero, because that's where we started. Infinite doubling of transistor density is a foolish thing to assume. Wikipedia says it's "approximately two years". |

Successful economic foundations require criminal activity liberty to thrive.
FTFY Thank-you. True words. Same thing.
The fun thing about liberty is that there is less 'crime' because there are fewer laws. |

He won't, if he's at all familiar with bitcoin and these forums. Look what happened to the Armoury donation drive. Only 30% of target with a project that is highly integrated with, and directly benefits bitcoin.
People don't like to donate bitcoins much. I can understand why.

I agree. 0.4 is a little high, 0.2 BTC threshold would work better.

No NSA can break 256bit AES by brute force.
How about cracking your encrypted e-mail message 100 years from now? Assume 1. Moore's law (doubling speed every year) ==> 2^100 times faster in 100 years. 2. Yearly doubling budget ==> another 2^100 times faster in 100 years. 3. Quantum computer ==> X * faster ? Moore's Law (transistor count increase in same surface area, NOT computing power) MUST be broken. The laws of physics guarantee it. To keep up with Moore's Law, a 1-billion transistor count must increase to 1 trillion in just 10 cycles (15 years), and 10^15th transistors (1 billion times greater) in 30 cycles (45 years). |

Run the numbers again. Sure it is fairly bad pricewise, but it has the potential of being actually quite efficient, both on electricity and more importantly on space. Instead of having a CPU/RAM/mobo for every 8GPUs, I have 2 CPUs (could be 1 if I wanted), some RAM, and a mobo for up to 36 GPUs (including dual-GPU cards).
I assume CPU cycles will start to become significant with that many GPU's and miner threads. Will a single core CPU be enough to run all of that without becoming a bottleneck? |

If you have the coin, I'm now willing to consider offers entirely in BTC, though I would like significantly more than asking price as I'll need to sell off a good number of the coins (at least half to give to the other owner) and I suspect I'll run into serious slippage issues.
Interested in the first house sold for Bitcoin? PM me!
If you sell off the BTC slowly over a week or two, you will not move the price much. The depth chart on the bid side has ~50,000 BTC total bids between the current price and $4.85. |

Since BTC is not good at issueing loans (especially small loans), it could will not replace banks in any foreseeable future

I'm expecting network hashrate to start dropping 2-3 weeks before the halving. Marginal GPU miners will want to balance "mining to the bitter end", with, "beating the rush to sell GPU's on ebay" After the halving, you will see an instant drop to 60-70% of pre-halving hashrate as the rest of the marginal miners do the math and figure out they aren't paying the electric bills anymore.
Sigg
The other interesting question is: where will total hashrate be in 7 months? This chart shows about a 30% increase in mining in three months beginning in December 2011. If price remains stable, (it may rise in anticipation of the block reward halving) the global hashrate could double between now and December if bitcoin keeps making headlines. I think the market will have these events priced in before they arrive. |

Thinking another way lets pretend Satoshi had made the block reward 25 instead of 50 for first 210,000 blocks. Do you imagine the price of BTC today would be the same, lower, or higher?
Interesting question. I'm tempted to say it could be the same, because if the price is purely driven by the market psychology. However, since bitcoins are not infinitely divisible, there is only half as much bitcoin with 25 block reward. That is not psychological, that is purely a supply problem. So I speculate the price must move higher. |

1st place payout confirmed. I want to thank Matthew for the inspiration.  |

free bump. You will get an offer soon enough, just be patient. Bitcoin is a fun ride - enjoy! |

Come on Matt, you don't give these "banking elite" much credit for intelligence.
If bitcoin truly is a threat, it would need to be stopped early.
Oh, I give them plenty of credit for intelligence, so much that I am dumbfounded why anyone thinks it would be more than trivial to stop Bitcoin at this point. So... if you think they think bitcoin is NOT a threat, why do you support bitcoin? By that definition, bitcoin is a failure if it doesn't upset the "banker elite" applecart. |

Only daydreaming sociopaths like OP would think that bitcoin is currently important enough for anyone to bother with. We have less volume than Second life's Linden Dollars for Christ's sake.

Whats really is bad from a user point is the huge block download, people will think it sucks, but my guess is that it will also
be adressed.
This is pretty much the only thing that is not optimal. People have no problem waiting two hours to download a movie. |
