Now that's interesting, because there are likely to be a couple of difficulty adjustments during that 30 days.
It should still be a win. Either the bitcoin community increases and (hopefully) the value of bitcoins or you get a few free bitcoins. |

Next round: 1 Mhash/s for 30 days for 15 BTC in any fractional amount (e.g. you can rent 2 khash/s for 0.03 BTC). Email me at tcatm@gawab.com to order. |

I sent the generated bitcoins. For easier calculation I also sent coins to people who joined a day later. The 30 Mhash/s generated 3.69 blocks during the last seven days.

I try to keep it running 24/7 but I can't guarantee that uptime. So far 1 Mhash/s has generated about 4.27 BTC since monday.

Performance shouldn't be measured in multiplies of the CryptoPP miner. Maybe you could give hashrate examples for typical CPUs.

I've sold some bitcoins to them. Wire transfer arrived just a few days later.

So this is like a futures market for gold mining, as you are selling contracts based upon your mining capacity. Hmm.
I like the idea, but there is no way that I can see that your customers can audit you, or otherwise verify for themselves of your honesty. Would you be willing to go to the extra trouble of a self audit, and publish it in some manner?
What is your business model here? In other words, what do you expect to gain from the renting of this generation capacity that you could not otherwise get from the generation capacity directly?
This is just an attempt to help people with less hashing power get some bitcoins. If difficulty stays low, I'll actually give bitcoins away for free. I think there are many users with less then 1 BTC and some that have > 1000 BTC. those with only 1 BTC can't afford to pay services with bitcoins and mtgox keeps the bitcoins for 30 days because of paypal. |

Possible to pay with another method other than bitcoin, as i don't have any at the mo.
You can buy bitcoins at mtgox.com or get 0.50 free bitcoins at the faucet: freebitcoins.appspot.com |

so if I understand correctly, you take all the coins the cluster generates in a week and divide them among the investors, in proportion to how much Mhash/s they rented? Or do I only get the coins that "my own" rented GPUs generate?
You get what your rented Mhash/s would have generated on their own. The interesting part is, that this can be far less than 50 BTC. You could invest 0.50 BTC and get 1.2 BTC after a week, even if one Mhash/s would generate only one block every two months. |

I'll plan offering service that'll allowing you to buy Mhash/s of my GPU cluster for a limited period. You'll get a part of the generated coins after a week according to the number of Mhash/s you bought. So, if you buy 1 Mhash/s for one week for 3 BTC the cluster will generate about 5,5 BTC for you which you will get after the week. You'd win about 2,5 BTC in this case. If difficulty goes crazy or the cluster doesn't generated a single block (unlikely) in that week, you'll get less or even nothing. You can buy more or even less than 1 Mhash/s. For easier calculation the amount you buy must be in multiplies of 1/6 Mhash/s. 1/6 Mhash/s for one week = 0.50 BTC I'll offer a total of 30 Mhash/s. If you're interested please email me at tcatm@gawab.com with the amount of 1/6 Mhash/s-chunks you want and your bitcoin adress for payment. I'll then give you an address to send the bitcoins to. For 2 Mhash/s buy 12 chunks. If this works well, I'll start a service selling up to a few Ghash/s. Update: 0 Mhash/s left |

$400 will get you 2x M2050 for two days. The free trials are hard to get as they're very popular.

Could a few people please run this special build? It'll amnesty the dust spam transactions, which will clear up the 0/unconfirmed problem for now. We really just need one block letting them through to clear up the previous transactions. Post if you generate a block with this.
I generated 8 blocks with the patch. |

I just had a chat with them. Basically you can rent them at $1.18/BTC assuming the same performance per Teraflop as ATI cards. That is, if difficulty doesn't increase...
|
|
|
|
|
It's running. Should find a block within 3 hours.

Three GPUs (ATI HD 5870).

Can you include the source? Or better the diff for those transactions? I could run it on my 983 Mhash/s box.

I'm looking for a web developer to help me write a bitcoin-based service. I'd prefer a clean ruby or python solution, but PHP would be okay if the code is clean and not buggy.
I'll do the webdesign myself so a nice template system is needed.
Features needed:
* interaction with bitcoind over a proxy
** sending/receiving payments
** maintain list of user accounts
* some kind of list of goods
* some static pages
I'll be paying 1000 BTC. Contact me for more details.

Please remove me from the list. I'll continue forwarding but it's too much hassle for too little gain (i.e. sending someone 0.01 BTC isn't going to make bitcoin grow much).

You should benchmark all implementations (using cpu time, not realtime) and choose the fastest and while benchmarking check whether the algorithm actually works.
