Re: Avalon Asic chip Mini USB miner [Post if interested]
by

@BkkCoins:
1) What's the BOM for that? (part specs)
2) Looking at the small size of this, it should be feasible to make a 2-4 chip version of this, with very minor modifications. That would be an excellent choice as it would beat most GPU's and FPGA's. People seem to insist on USB hubs and so on, but that is completely irrelevant if one just replaces the USB power with an external standard 5V@2-3A (10-15W) supply.

In any case, if you can get this working, I'd like to buy one of these from you for a public art project to promote crypto-currency adoption. [I know it may sound little, but as I have given up on making any kind of profit on this subject, I've moved towards not-for-profit-projects that help educate people about the future of banking and currencies.]

Come on guys, you seem to start falling for this astrology scam! In the end you'll have to look in the stars for your miners! The specs for the Mars is simply ridiculous and the Jupiter specs are essentially useless.

SCAM!!

Re: New Halfsize Avalon "proposed" in latest update -- 45Gh/s

^^ Since we're rapidly approaching the "point-of-no-ROI", there's little interest in investing several thousand USD's on half-a-miner. However, if you were to release a smaller device based on 2 of your module PCBs, giving us a much more affordable ~5.4GH/s device, there would probably be a higher interest. The additional effort for such a device would be minimal, and DIY guys could always expand upon it, using the same controller module.

Re: Building the next generation FAST CRYPTO CURRENCY MINING MACHINE

Surprised at my own ignorance and the apparent lack of reaction of knowledgeable readers of this thread, I found out about PPCoin (PPC). Apparently PPC tries to solve the mining HW race problem, by not only minting by proof-of-work (which is HW minable), but also by proof-of-stake (which allows for long-term average-Joe profit). They have their own forum HERE.

I strongly recommend everyone to have a look at the following 2 papers:

1. "Synthetic Commodity Money" [George Selgin, 2013]
2. "PPCoin: Peer-to-Peer Crypto-Currency with Proof-of-Stake" [S.King and S.Nadal, 2012]

After having briefly read the above articles, I am more convinced of the decline of Bitcoin as described in the OP. Although, Bitcoin may very well be a great currency for the next couple of years, the number of miners will steadily go down until we are eventually left with commercial mining operators (like already mentioned) and a small hard-core group of amateurs, mining mostly out of academic interest and not-for-profit. Therefore, it seem fair to say that a crypto-currency based on a more evenly distributed minting process (e.g. as proposed by PPC) will eventually take over.

For a complete list of other crypto-currencies look HERE.

Another, perhaps more philosophical question. Should we really be using "mining operations" that require wasted energy? It just doesn't seem to make sense to make zillions upon zillions of calculations, just to be able to create a quasi-physical (here crypto) currency to put into circulation... Is there really no other alternatives or ideas how to go about this?

Interesting thread. I had a brief look at the original Scrypt paper (which is quite old), but it was not obvious to what is meant with making memory intensive tasks more expensive. I'd like to see this quantified using numbers with today's memory technology. In addition it was even stated in the paper that one of the limits were based on 2-dimensional memory ingots, which we know will change in the next couple of years, to become 3-dimensional blocks of some electro-optical substrate. This is will have to effect of increasing memory size with x3 instead of x2 for the same price. Now, if there's another way of mining that we could think of, that could avoid the mining growing pains into adulthood, that would be very interesting.

The registered office required to open a company in Sweden may be any address where the Swedish company declares to have its headquarters. The registered office will be public.

Could someone go over there and take a picture of their (Sam Cole et.al.) mail box? And perhaps knock on their door and ask if they are indeed working for such a company as claimed here?

By now, they've had their chance to come back with some minimal feedback to confirm their business... But their silence is speaking for it self: ASICs DOA.  ETA = oo

Pretty cool -- I'd love to see a walkthrough/narrative of what you've done (that is to say, once you've arrived where you want to) to get fpgaminer up and running on the ML605. I'd be keen on picking up one of those boards to muck around with, but would be a little more confident with a primer.

Double that!

@Epicblood:  Please post any relevant links to where we can get the parts needed to follow you on this project! Apicture or two of you current setup would also help.

Thanks PG for this depth.

I wonder what all those other 11 employees are doing... Contrary to what Sherlock Holmes (aka mobodick ) believes, they are probably not all bakers. In addition the number of ASIC pro's available in Sweden could probably be counted on two hands. So, at least to me, it is clear as day that these guys doesn't have the experience in ASIC design at the moment, and are desperately seeking help. (Perhaps Mobodick should apply for a baker job there. Wink

Second, the fact that this mysterious (Sam Cole) is "answering" the emails, kind of suggests that he might be the rotten apple here. What's he hiding and who's he hiding from? Certainly the Kennemar's are not going to rip anyone off, since we know just about everything about them, worth knowing.

Well, if you're so smart, why'd you just totally miss the point?

The point (for those who are not pretending to be smart asses), is that if they haven't even hired the right guys yet, we'll have quite a bit more waiting to do. Hey, what do I care? I've already promised not to buy into this project. Spend you coins man, just spend them all.

Seem legit, but it should be noted that they are currently looking to employ somebody with FPGA/ASIC experience.

Kompetenser söks till våra kontor i Stockholm, Göteborg och Västerås.

What does that mean? That they don't actually have enough know-how or that they are so busy they can't keep up the work load... Hm. I'd say the former, since they already have 11 employees according to image above.

So yeah, we'll be waiting...and waiting...and waiting.

Sure, I'll order AFTER you have provided that. It would not make any sense to buy anything before actually having a working sample in hand, or at least some independent Bitminer verification...

Seriously, I suggest someone (+bring friend for security)  in Stockholm area, go to their home and ring the doorbell, perhaps that would help verify two things.
1. That they are who they claim to be, and that it's not just the address of some old lady with dementia.
2. You can ask them outright, what's the current "status".

Re: X6500 Custom FPGA Miner

Yes, they are all gone, sorry. At this point, a new production run would take 4-8 weeks, and who knows if BFL will be making ASICs by then (or ever). It's just too uncertain for us to invest all that money and risk getting stuck with a bunch of units.

Hi,
I've been looking at this board, and must say I'm quite impressed of the "cleanness" and quality of your design. I'd like to get one for FPGA experiments, but that would require the accompanying VHDL/Verilog code to program it with. Do you have it available somewhere? (What experiments have you done with it?) Or perhaps I have misunderstood, and it is not possible to re-program these FPGAs while on board?
In addition it seem that you do not deliver outside the US?

Anyway, don't worry about the ASICs, they will not be able to deliver anything in the next 4-8 weeks. BFL has shoot themselves in the foot by poor design choice and need to redesign. This has cost them dearly, and we can question if they can even afford to continue this project, without mining for themselves first. Which is probably what they are doing right now, if anything. Also, the majority of people doesn't wanna dump 1500+ USD to an overpriced ASIC, they just wanna try the technology out of curiosity, which is where your board is perfect.

Wow, this is by far the most elaborate scam I've seen so far. Damn!

Isn't there any site regulation for obvious scamming behavior? (Why not?) These guys and their sock-puppets should be banned permanently. Or better, if Anonymous could hack them back to the stone-age.

A while back I posted several relevant questions, in post #204. They have answered several times since then, but never addressed these. That should be enough scam-evidence on this site, to get them banned! (Any mods here who'd care to explain or chime in?)

BTW. With 3 degrees of separation on Linked in, you have basically covered close to every random person. On the much larger Twitter, the average random person is separated by 3.4 persons! Thus the wankers using that as a criteria for being serious connections should also get banned!

Each chip has one core that runs at 250 to 300Mhz, 1 hash per hz.

No! To get through the SHA256 pipeline you need at least 66 clock-cycles! And this is excluding all other delays, loading/extracting the data etc... Unless you know something I don't!

EDIT: Yep, I obviously didn't know better...

BFL: Epic delays. Possibly a scam. WARNING: do not order until (and if) they ship consistently

BFL is definitely a SCAM, and if people can't get this into their heads, they might as well give away their wife/husbands and kids as well.
