Do you just remember the story or do you have any sources confirming this?
I remember I can fly when I want to.

If/when BFL comes with the ASIC and your singles/mini rigs will be swapped for something much faster, like 10 times faster.
Will you keep the bonds 5Mhash/s or will you upgrade them to a higher speed?

How are asic's dangerous for bitcoin?
51% attack? that would mean bitcoin won't have any value anymore because the 51+ entity can double spent so they loose the investment of the asic's.
Not profitable anymore for people how have lots of gpu/fpga's? So what, what about the people with lots of cpu's when gpu mining started? Bitcoin survived.
sha256 not stong enough anymore? Don't think so, at current difficulty (1,591,075) a little less than 2^53 hashes should be made for one block. Difficulty can double 200 times more!

What is the post ASIC era, anyway? I have been trying to figure that out. Quantum Computing?
Bitforce QC - Infinite Hashes, Power draw from Quantum Foam.
What I remember, but can't a source right now, is that finding a collision for hashing algorithms like sha256 would cut the time needed from 2^256 to 2^128. So it would still take a long time, and bitcoin block/share finding is not really a collision but just a small hash value, so I don't know if thats the same. |

Care to clue us in to which state you've moved to?

Did you use the --url http://my.pool.com:8337 --userpass XXX:XXX ? Thats just an example url and username/password. For example, if you want to mine at pool-x for me, you can use : minerd -o http://mine.pool-x.eu/ -O pieppiep.1:x -t 4 --quiet If you go to http://pool-x.eu/ of some other litecoin pool you can make an account and set the url and userpass correctly. For standalone mining I have no idea how you should do that. |

minerd --help -a, --algo=ALGO specify the algorithm to use scrypt scrypt(1024, 1, 1) (default) sha256d SHA-256d So if you use -a sha256d it will mine bitcoins. When I try it with my intel q6600 (quad core@2.4GHz) I get a little over 3 MHash/s each core, about 13 MHash/s total. Not really worth it, my older videocard gets 60 MHash/s with good miner. |

The password is to secure your wallet, so yeah, you're screwed if you don't have the correct one anymore.
Maybe you can restore a backup of your wallet? I don't know how that works, never had to do it.
If the password was somehow removeable, it wouldn't add any security.

I should stop posting when not fully wake up :S But I don't think it is a major fail, I just calculated something else by accident  |
|

And what I understand, they don't use a fully unrolled hashing core, they use multiple rolled cores.
Very interesting idea, an idea I also had but can't really test because I don't have the tools to try.

lol $1.22/GH I'll take 500!
Sorry, early in the morning here, not yet fully awake Edited and corrected. |

$90,000 for 110GH/s = $1.22 / MH/s
The BFL singles are $599 for 832GH/s = $1.39 / MH/s
So the BFL singles give you a little more speed, but since they use older fpga types, the BitFury costs probably less electricity.
Nice product!
/edit
BFL mini rig, $15,295 for 25.2GH/s = $1.65 / MH/s

I just monitored a little bit with wireshark, it's about 1kB per request to the server.
So if you mine at 4GH/s you have about 1kB to get work and 1kB to report work each second.
If you mine at really lower speeds you probably get a little more data per hashing power because you don't try the whole block.
At 800 MH/s it is about 5 seconds per block so it probably won't matter, but my videocard is as slow as 60 MH/s and would take a little over a minute to complete a block and thus would generate a lot of stales.
Conclusion, at 800 MH/s I estimate it at 2 kB / 5 seconds, 86400 seconds a day, 17280 times 2 kB, 33.75 MB/day.

Ik heb zelf een keer 7 bitcoin en een keer 16.6 bitcoin gekocht via https://bitcoinmarket24.com ook via sepa. Volgende keer ook eens bitstamp bekijken dan, klinkt wel goed. Bitcoinmarket24 is ietsje duurder dan de koers van mt gox, maar wel makkelijker vind ik omdat je geen account hoeft aan te maken. |

What's about 20th may dividend payment? :-)
The 21th, it's today. |

10d 7h on the spot  Nice! There is a bug on the website, here it is saying 10d 12h. -5 hours have passed since Garr255 posted. |

Good luck selling your FPGAs. It's what I have been saying ALL along but some of you don't listen. Once the new generation like Lancelot comes out then your Icarus becomes useless but now since mining is profitable it is OK but good luck selling If a new generation of fpga's would make the old ones useless, wouldn't the new generation gpu's the old ones useless? |

I'm interested in the proof of work concept used in the cryptocurrencies. The one used for bitcoin I understand and implement if I want. The one used for litecoin is a bit harder to find. Until now I just find I should replace the sha256(sha256(block of 80 bytes)) with scrypt(block of 80 bytes). The problem is the scrypt hash, I can't find a clear description. I know it somehow generates a pseudo random block of data with a length of 128kB and does some pseudo random mixing of that block. The sourcecode of the cpuminer I found is to optimized for me to read. Does anyone have a link to some pseudo code like the one on http://en.wikipedia.org/wiki/Sha256 but for scrypt? |
