You'll see.

The difference between Hardcopy and real asics has been explained several times, just look it up.
One last time: Hardcopy is the same device as an FPGA except there is a metal layer instead of the routing, so there is marginally lower power consumption and marginally higher speed. Its a little better than the difference between different speed grades of the same fpga. Several people many of them professionals in the field have said this if you don't believe me.

btw: nicely done for finding this thread after 13 posts  Roll Eyes

just looking at the network hashrate... something goofy is going on,.  how do we go from 15000 to 22,000 within 24 hour period ?  I have never seen such large swings until lately.

I thought the "network speed" was based off the rate at which blocks were being found, and estimating it from there. If everyone happened to have a 24 hour streak of bad luck, then the graph would dip. If everyone had really good luck tho, then the graph would swing up. Thats why I like the 3day average.

Tips? 1crazy8pMqgwJ7tX7ZPZmyPwFbc6xZKM9

Uhmmm, Im pretty sure that luck is directly realated to the number of blocks being solved in relevance to how many your pool is solving..
The only way what you saying could happen (i think) Is that if a Solominer Nailed >50% of the blocks one day, And then hit close to none the next..

goofy?

hashrate follows exchange rate (with a noisy lag of 1-4 weeks), cost for running mining equipment has been falling => everything normal. I'm not saying BFL is not "testing their new product", though. That also would not be goofy.

Don't you guys remember that the Singles were claimed to contain custom hardware?

It will either turn out to be an exaggerated claim or even a scam.  
inb4 BFL fanboy shitstorm.


anyway just posting that so I can bump it next year with "I told you so."

My point being: BFL the way it is presented to us certainly hasn't got the resources and funds to develop custom chips.

well i certainly hope its an exaggerated claim/scam  i just purchased 1500 BTC worth of mining hardware (hoping its not true) if it is indeed true im going to say bye bye to all my profits Sad

Custom slingshots for bitcoin!! HANDMADE.

You might want to consider than, besides BFL, an additional three companies are allegedly developing ASIC Bitcoin miners:

They do now.  Undecided

By custom chips I mean Full Custom ASICs, that is what they are claiming they are making. That costs about 10M USD for starters.
There might be some way to get it cheaper if you have the ties but unless whoever behind BFL is some engineering wizard he doesn't even have the means to develop it.

If you know how the process of semiconductor manufacturing actually works the notation of a BFL custom ASIC is ridiculous.
To get an idea what kind of people pulled this thing off in the past... (Ninja Style ASIC development using selfwritten software), he did it: http://en.wikipedia.org/wiki/Charles_H._Moore

If you truly think that BFL cannot achieve, oh, say, 350 Mhash/Joule, then you can easily make 50 BTC by betting as little as 0.1 BTC (since people have yet to bet against my entry on betsofbitco.in). See https://bitcointalk.org/index.php?topic=109357.0

If you will guarantee me 500:1 odds on this bet, I'd take it in a heartbeat. Unfortunately, betsofbitcoin doesn't guarantee odds: someone could come in after me and place a bet and ruin my odds. I don't make bets for which I don't know the odds.

If you require 500:1 odds to bet, this means you think 350 Mhash/J may be doable.
Therefore you are not the person I want to bet against. I want to bet against those who claim 350 Mhash/J is plainly impossible Smiley

Would you be willing to escrow a bet amount at 500:1 odds?  If so, how much are you willing to risk?

If you're searching these lines for a point, you've probably missed it.  There was never anything there in the first place.

I have to admit, I've been a chip fabrication nut for 30 years and I just can't figure out how the hell they can build this within the scope of power they claim. They have (again in my opinion) zero chance at getting access to 45nm or lower wafer starts with this small a market, so that leaves the larger processes only. Given that, the power doesn't add up. Even at 45 I'm thinking the power claims wouldn't add up.

But anyhow, it's put huge uncertainty in the mining market and may have been partially responsible for keeping difficulty down as people eschew the purchases of new hardware either GPU or other.

Guess we'll see.

Anyone taking real bets on this? I'll take a piece of the triumvirate .. that they miss POWER, HASH and DELIVERY DATE claims as they are now.

how much would you have to pay for global foundries to make you a 45 nm wafer?

It is pitch black. You are likely to be eaten by a grue.

I'm willing to bet 2 BTC on this, if you are also willing to escrow your 1000 BTC with a party we both trust.

I might be interested in a bet based on your claimed power specs Inaba, depending on the odds. 1TH/s from 1250W or less at the wall for the SC Minirig. Would you take a bet like that at 100:1 odds?

Here's the thing, I have no problem taking the odds from either of you... what I do have a problem with is tying up my BTC for so little return for weeks at a time.  I mean, tying up $1200 to win $12 for a few weeks is just not lucrative for me.  I mean, it's a guaranteed win for me, but the lost revenue of not having access to that money does not make it desirable for me.

Are you willing to do it without escrow then? Or are you afraid I'll run away with the 2 BTC in case I lose? Smiley

Sure I can do it without escrow, but please define the bet specifically before I commit.
