No new algorithm - you cannot 'improve' the existing one, this is simply an exercise to reduce critical path delay on an ASIC (not an FPGA)
You cannot "improve" SHA-256. You can however, improve the Bitcoin hashing algorithm. How is this possible? Look at the ZTEX FPGAMiner. Also, there are many ways to implement SHA-256 in silicon & FPGA. How you construct your pipelines, loops, resets, etc, all matters. At the end of the day, you cannot avoid most of the work done in the SHA-256 passes that Bitcoin uses, but you can make that work be done in a more efficient way.

One of the qualities I look for in an escrow is the ability to convincingly pull off referring to themselves in the third person. ![Grin](https://bitcointalk.org/Smileys/default/grin.gif)

I don't. He made a fortune with his Avalon already.
He's pissed because he's not making a fortune anymore. Many will feel this way in the near future. That much is certain ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) His Avalon is still cranking out $5K a month. That is not too shabby. It just won't do that for very long. Certainly not long enough to spend $25,000 on buying another one.

wow bitcointalk took a shit on this thread,
blackarrow is just setting a price, get over it, if you dont like it move on or comment on it
Since this is a forum for commenting on things.

250BTC per avalon? ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fcox-supergroups.com%2FShutUpAndTakeMyMoneyCard.png&t=665&c=hTMMsqVq7cyBWg)

Anything above 20BTC is way overpriced.
Considering the difficulty crunch that is about to rear it's head on people. There won't be a reason to imitate Avalon previous price points for 65Gh/s.
If they can't sell it at well below 20 BTC then they are certain to be a future defunct company. Period.
KNC/BFL or whoever, it applies.
As difficulty increases companies WILL lower their prices or people (except the most foolhardy) simply won't pay it. There is no incentive to throw away money on an ASIC that will just barely eek out it's own cost.
I think there will be a round of fools who will get fleeced. After that, prices will return to earth.

FWIW I've paid for an order of chips and have requested developer chips and reference docs. When I get those I will post the docs here and then send the chips to whichever dev's have the community's support and can put the time into actually producing an actual working board.
*Note - I don't want to hear how this is a stupid purchase. I've done my risk assessment and think this is a good commercial opportunity. If you disagree with that then please keep it to yourself.
Or, if people think it is a bad purchase they could post it here and you could refrain from reading it. Unless you work for the NSA that is. ![Grin](https://bitcointalk.org/Smileys/default/grin.gif)

Will you be accepting paypal?
No. We have had bad experience with PayPal few years ago and we promised ourselves not to use them anymore. We accept bank transfer though. It's more reliable and cheaper. But no recourse for refunds.

Not interested at that price; not really even close to a break-even situation. n a Diff will be 40MM at delivery, and thats if you actually hit your timeline. You need to consider margins far lower than the 100% your trying to get, especially o preorder.
Anyway; good luck, others might be interested.
Why is an Asicminer Blade with 13Ghash worth 50BTC and Avalon 65Ghash doesn't worth 99BTC? IIRC, the ASICMiner blades were already built and ready to ship. If BlackArrow slips by a month (due to supplier delays beyond their control for instance), it could severely compromise the profitability of the transaction. It is an additional element of risk that cannot be easily quantified.

in this article http://www.coindesk.com/butterfly-labs-ship-first-bitforce-sc-60-bitcoin-miner/ they say following: “Now on to shipping. In the ~8 hours I was there I saw 2 people box up and ship out 2 large shipments with well over 100 orders… Notice orders, not Jalapenos, some of those orders had up to 4 Jally’s each in them, and one of the 2 people who were working in the shipping dept was only on her second day working with BFL. Shipping by no means will be a bottleneck, they can box up thousands of orders a day with 6-10 people working a good day I would assume. I saw how MiniRigs are going to be boxed up... well these "100 orders" are all jally's atm i believe. quote mentions to notice they're orders not jalapenos, but in reality they are orders consisting only jally's, as my early 16XX order made within 2 hours after bfl announcement of pre-orders last year still shows status "processing". but i guess we're getting closer. I don't think singles have gone out customers yet, but at least one single has shipped to a dev. ![Undecided](https://bitcointalk.org/Smileys/default/undecided.gif)

In my opinion, BFL is decent option compared to their competition at the present moment. I know they've had issues in the past, but they fact that they are cranking out Jalapeno's is very encouraging.
Lets compare them to their competition:
1.) ASICMiner - The price of their blades and usb miners is a complete ripoff that will likely never earn back what the cost in BTC (cost over $400/GHs).
2.) KNCMiner - This company looks encouraging, but they still have a long way to go before they can ship a working product. I'd give them a 50/50 shot of shipping anything in 2013 (Cost of ~22$/GHs).
3.) Avalon - All you can do at the moment is buy the chips and hope you'll be able to turn them into a working miner in a timely fashion (assembled cost and delivery unknown, but Terrahash is selling for ~50$/GHs).
4.) BitFury - I haven't been following this company that closely because I don't feel comfortable ordering anything priced in BTC from Russia.
5.) BTC - Shipping Jalapeno's, huge backlog being worked off at about the rate of 1 month per week, cost of ~$50/GHs.
6.) Buying used ASICs secondhand is also a complete ripoff with prices of Avalons going for ~$500/GHs.
You can either buy 2 USB miners from ASICMiner (600 MHs) or a 7 GHs miner from BFL for 4 BTC. If the BFL Jalapeno ships in the next 2 to 4 months, which I think will happen due to their recent performance, there is a clear winner.
I understand that some folks with early pre-orders are pissed at BFL, but if one does the math and tries to take a truly unbiased view of the current ASICs landscape, BFL is not a bad option...
There is one problem with your calculations. If BFL delivers their entire backlog, that could add 200-300 TH/s to the hash rate. Tripling the hash rate (even before the Avalon/Klondike wave hits in Aug/Sept/Oct). That would cut returns for BFL single & mini-rig owners by one third. If BFL does not clear their backlog, you cannot get a device ordered today from them until they do. It inserts an large element of uncertainty. ASICminer is just gouging because they can. Currently, they are the only ASIC company that will deliver an order you place today within a week.

Finally, an end to the BFL saga is in sight. Hopefully they get their orders out faster than the Jalapenos.
