I was the first who called Pirateat40s Savings and Trust a "classical HYIP scam", right after his OP. Yet I didn't take part in Matthews bet - get it?  It is not my intention to taunt when I tell people to put their money where their mouth is by betting 'disagree' on http://betsofbitco.in/item?id=665 I tell them that to hopefully stop (or at least reduce) the length of the debates on the forum. So, no, I honestly don't get it why you don't participate in a bet like mine, even a symbolic 1 BTC... If one thing, it tells me that you doubt your own claims (or don't care enough?) |

Culculations how much faster the hardware needs to be to proof I can't just crack a bitcoin address :I've found at https://en.bitcoin.it/wiki/Technical_background_of_Bitcoin_addresses how an address is calculated. To generate a specific address that already has bitcoins I need to calculate at average 2^160 keys. At http://www.bitcointrading.com/forum/bitcoin-software/vanitygen-vanity-bitcoin-address-generator-%28v0-17%29/ how quick addresses can be generated. The fastest graphics card for this has a rate of 23.5 Mkeys/second. So lets round the generating speed to the nearest 2^x speed, we get 2^24 keys/second. On average we need 2^160 / 2^24 = 2^136 seconds, or more understandeble human language, more time than the universe exists. If I want to be able to crack an address in less than a day, for example a little over 18 hours (to get a nice 2^x seconds), I have 2^16 seconds to do it so I need to be 2^136 / 2^16 = 2^120 times faster than with the current hardware. If I take into account that at the moment hardware still get 2 times faster each 1.5 yeah, I need to wait 180 years for hardware capable of breaking a bitcoins address within one day. So technically it is not (yet) possible to do this kind of thing. My actual questionWhat if someone or something is able to do this kind of calculations, and thus can spent every coin mined today, or is just very very very lucky and finds someone elses keys without hacking into other computers. Will it be legal to spend the coins? This topic comes every once in a while. If someone can calculate key collisions quickly, then he can also calculate SHA256() quickly (or cryptographically break it), as this hash function is used to calculate Bitcoin addresses. But if he can calculate SHA256() quickly, he can also mine quickly, as mining is based on SHA256(). Therefore, what do you think is more profitable: running a GPU for "more time than the universe exists" to perhaps collide with a single address, or running it to mine and earn Bitcoins every day? Obviously, address collision is computationally a non-issue. |

Considering gigavps has a vendetta against Tom and btcfpga (and obvious bias towards BFL since that what he invested in) expected him to he hesitant in reporting numbers that are comparable to BFL.
It just amazes me to see BFL claiming to have reached 1J/GH. If it were April 1st I would be assured it's a joke. I simply don't understand how they could push that technology so hard in such a limited amount of time, and competitors don't get even close to it. Why can't you understand? Simple math shows that 950-1500 Mhash/J should be possible with a 65nm ASIC: https://bitcointalk.org/index.php?topic=95762.0 |

To clarify: Do they appear in your wallet as soon are they are mined?
They do go to your wallet, assuming you put an address in that wallet in that block. For example, look at the first transaction in http://blockexplorer.com/block/00000000000000a4d73468e752d7eb54ac8de5c131188361a811676ecbd67228and you'll see it specified an address as the destination for the generation of the block. However, it's not immediate. You need to have 100 confirmations after you mine a block before the network recognizes that you own the coins, so it's going to take about 16 hours 40 minutes to show up. What Fjordbit said is correct, except it is 120 confirmations, not 100, meaning they mature ("show up") about 20 hours after having mined them. (I am a solo miner.) |

Hi Dust, I think is is fair to say that it is not clear what Tom is saying there. I would rather wait for him to announce the info and then we can add it to the list. Best, gigavps Tom said exactly in the above comment "[the 27Gh/s device] uses less electricity than the ModMiner Quad", so it is pretty clear to me that it means less than 40Watt. Hence 675 Mhash/Joule, or 1.48 J/Ghash. Now if you wanted to be pointy, one could say that Tom did not promise the 54Gh/s device would have the same efficiency as the 27Gh/s one... |

Wait so.. conservative estimate... then planned they to update firmware for faster speeds to be competitive? Doesn't this seem a little bit odd (or even underhanded) to anyone else?
Actually I'm not exactly sure how a firmware change can gain 50% performance unless the one they were going to release simply ran it at 66% of maximum clock reliable speed ... A firmware update could have unlocked certain previously unused parts of the chip. Just like a BIOS tweak can unlock the 4th core of certain Phenom processors sold as 3-core. |

CJGoodings: since you don't believe in BFL, how about you put your money where your mouth is by betting against http://betsofbitco.in/item?id=665 ? You could double your money if you are right... |

I've recently been challenged with this "criticism", "all cryptography is breakable, it's just a matter of time", and thus concluding that bitcoin is not safe.
Very simple counter-argument: "online banking uses cryptography too (HTTPS), do you also consider it unsafe?" Of course not. When cryptographic flaws will be found in Bitcoin, they will simply be fixed by an update of the protocol and algorithms. Very much like HTTPS had to be "fixed" in the past (BEAST attack, MD5 collisions, etc.) |

Everything we can see about vescudero (but especially the things we cannot), are signs of a ponzi.
The only reason for him to return all funds now is to come back a couple of months from now and re-open with huge momentum right from the start.
But there is a big piece of evidence in his favor, which is that we know exactly who he is (with pretty high assurance). Pointless argument. Case in point: we knew pirateat40's identity before he defaulted (Trendon Shavers), yet he ran away with his Ponzi profits...  |

I've seen no good news about a guy that just wants to run a single rig at his house to have some fun, make a little BTC to pay off the rig.
I think the days of the hobbyist miner are gone. No. Hobbyists will still have a place. You have to understand that when you spend $1 on an ASIC product, whether it is on a tiny Single SC, or on a large MiniRig SC, you get roughly the same amount of mining performance: respectively 31 and 33 Mhash/s. Therefore, large or big miners generate similar amount of profits. And in fact, small miners are generally more profitable than large miners, as they don't have overhead costs. Eg. the teenager mining on the family PC does not pay directly for electricity (his parents do) and does not have to rent space in a datacenter to host his hardware. |

No, I'm not a miner. But I know a scam when I see one. And this is a scam. S.C.A.M.
You are wrong, and you don't have enough self-confidence to put your money where your mouth is by betting against BFL here: http://betsofbitco.in/item?id=665 |

Let me make my reasoning more succinct.
I cannot knowingly associate with convicted criminals who have engaged in crimes of moral turpitude, especially those involving money.
This is admitted to. By coming to KC, I would have to answer to that.
And do not act the aggrieved party. Grow a pair and man up. You're better than this.
Didn't you trade with and defend on the forums pirate, who was running an obvious ponzi scam? I did trade with pirate, and in retrospect, much like imsaguy (without the PPT), looking back on what started innocently enough, it's pretty darned obvious I should have been more careful. This is the first time ever that I see you admit being wrong. The fact you almost never admit it is precisely why people draw you into endless arguments. Case in point: your argument with Inaba right here. If you recognize this, you may have a chance to improve your reputation... |

Plug will be the same (5.0mm OD, 2.5mm ID), so it's possible to use the same plug.

Nasser, Are you Nasser Ghoseiri, as reported in this interview?: http://codinginmysleep.com/interview-with-sonny-vleisides/Is this you, a senior FPGA engineer?: http://fr.viadeo.com/en/profile/nasser.ghoseiriIs this your Facebook page?: http://www.facebook.com/nasser.ghoseiri (this person "liked" BFL) How can you be BFL Chief Technology Officer... http://news.yahoo.com/butterfly-labs-announces-next-generation-asic-lineup-054626776.html...when you post on Facebook, this month, that you started working for a large european bank: http://www.facebook.com/nasser.ghoseiri/timeline/story?ut=32&wstart=1346482800&wend=1349074799&hash=10151430077673378&pagefilter=3&ustart=1Did you recently resign, or significantly reduced your involvement with BFL? I have no doubt BFL will continue to succeed and grow without you, but if the above is true, I think customers would like answers. Regarding employement for a bank, I'm a senior IT consultant / architect there. It is necessary to be an employee for maintaining your residency permit until you obtain nationality. The time I dedicate to our corporation has dramatically increased during the last 4 months, to about 7 hours during work days and a minimum of 25 hours during the weekend. I hope this answer helps. Regards, Nasser Thank you for the honest answer. I am satisfied. (I could not imagine someone in your position working 2 jobs. Crazy workload!) crazyates: what I did is called due diligence, not stalking. |

30.768 Th confirmed so far...
455 Confirmed orders...
67.62GH per order average...
* 7029 orders =
475.315Th
19x Current ~25Th
No adjustments for unfilled orders
One adjustment people are leaving out: People were/are still ordering FPGA Singles on the same order system, they are also included in the order # range. Why would people still be ordering FPGA singles? That would be plain stupid and a waste of money. Your ROI will grow tremendously when the ASICs start to come in. I think that's because some people don't believe in miracles. Planned efficiency of SC ASICs looks incredible. Think so? Please do put you money where you mouth is. Bet on http://betsofbitco.in/item?id=665 |

Jutarul, arklan: what makes you think BFL will use an old 130nm process like friedcat did? Power efficiency increases with the square of the transistor junction area. Do the math at 90nm, or 65nm. I will win the bet  If you disagree with me, please do bet against me on betsofbtco.in! |

Who are the owners of BFL? Does Sonny own 100% or is it shared between him and others, eg. the venture capitalists mentioned in the ASIC press release?
I understand that BFL, as a private corporation, is under no obligation to answer these questions, so thanks for doing the town hall.
