I'm wondering whether or not there is interest around here for a Semiconductor Fab company to accept bitcoin for their services - that is, creating and packaging silicon ICs based on digital designs that are sent with the order.

Orders will probably be limited to a minimum of 500K USD (the approximate cost for a Mask to be made), and can range up to the millions (depending on the number of silicons wafers used). This may be a problem, since bitcoin doesn't (yet) have that much liquidity. All bitcoin funds would most likely need to be immediately converted to fiat, especially due to the risk of the bitcoin/fiat exchange rate destabilizing and since there is not much use (for the company) to keep funds in bitcoin.

Benefits would probably be limited to just anonymity, since it is _impossible_ to achieve the amounts of bitcoin needed simply through generation (unless one is a hoarding early adopter) and the use of exchanges would be needed. Not too sure why one would need anonymity in the semiconductor industry, however.

Unless liquidity is an issue, fees can be kept relatively low.

Fiat -> Bitcoin -> Fab -> Fiat.  (Most likely circumstance)

Anyway, just wondering 

1)    BitForce SC Jalapeno: a USB powered coffee warmer providing 3.5 GH/s, priced at under $149
2)    BitForce SC Single: a standalone unit providing roughly 40 GH/s, priced at $1,299
3)    BitForce SC Mini Rig: a case & rack mount server providing 1 TH/s, priced at $29,899

This is going to completely decimate the FPGA and GPU industries, if Butterfly Labs is able to keep up with the demand.

*Looks at my poor little 5770 at 220 MH/s, and then at BitForce Jalapeno at 3.5 GH/s at 'approx' same price*

"Aw crap!"

OFFER FULFILLED BY BURTW, CLOSED FOR NOW.

I know that the amount is perhaps too small, but is any reputable or friendly and active member willing to lend me 1 BTC for every period of 5 days or so? For an illustration of how this would work, you would give me 1 BTC today, and I will give you 1*(1+(agreed interest rate)), or around 1.09 BTC in five days, upon which you would give me another 1 BTC or so. You would, of course, have the option of either having me just send the interest to you, and continue on using that 1 BTC, or have me directly send it to you, and you would then decide whether or not you would want to send it (minus the interest) back to me.

I want to do a sort of pass-through to pyramining, except on a (ridiculously) small scale that my account there can actually keep up with. Due to the slight volatility of the payments, and the relatively small size of my account, I can currently accept only 1 or 2 BTC loans. Of course, if pyramining fails or doesn't keep up, though the former is unlikely since I have already compensated for it using the relatively lengthy 5 day term, I have a 5770 mining 24/7 earning approx. 0.12 BTC per day that would give you a guarantee of my repayment (though not by the due date).

It's just a small experiment to give others the high interest of pyramining as well as allow me to increase the size of my account there. If anybody would like to continuously do this, and be sort of a partner with me, I am willing to give you full interest minus trans. and pyramining fees. Quite a bit more than your current offered interest, I would say. Perhaps even better than BTCS&T passthroughs.  

Anyway, if anybody's interested and are willing to spend the time, PM me or reply here.  

[7.61 MH/BTC]

Join the New Pyramining Mining Venture before it gets too late! Unlike what its name suggests, it is NOT a pyramid scheme but instead is an extremely profitable sustainable mining operation.

To get a gist of how it works:
1. You deposit BTC.
2. BTC is (immediately) used to allocate/buy FPGA hardware.
3. Your account is credited with a certain amount of MH/s depending on the amount you deposit (the rate is currently an amazing 7.61  MH/BTC)
4. Every interval (which is in my experience around 4 times everyday) you get a certain amount of BTC back depending on the amount you deposited and your account's MH/s.
5. Once your pending balance reaches 1 BTC (or the fulfillment of your deposit amount + bonus), it sends it to your receiving address.

Typical Bonus is 5%, whereas if you register with a referral, you get 10%!

The estimated breakeven rate is around 8 months right now, much less than any mining bond available! In addition, the amount you deposited previously does not simply go away - you are still allocated that much MH/s, which can be used to quicken later deposits. At least that's what I've been doing  

So register! =D (Profit + Support P2Pool, it's all good!   )

Hi all!

It seems to me that this might be a rather stupid question, so if it is, please forgive my 'insolence' or incapability of answering this question myself.
Is it possible to 'reuse' a previously generated hash? An example would be a miner that would do as it would until it finds a solution for the particular work. It would then save that hash in its memory and attempt to reuse it as a solution for the next work. If it doesn't meet the requirements, the miner would then continue on hashing until it found another suitable hash, which would then be stored and used again, continuing the cycle.

The wiki articles don't really seem to touch upon this issue, since all they say is that as long as it is underneath the target, it would be fine.

EDIT: Okay, it seems like the wiki 'indirectly' answers this question. If it actually does not, then feel free to answer it. Otherwise, close this? I find the description of the nonce value somewhat confusing, however...
