Oh, what a coincidence ! Lolcust has not logged on since 14 February and ArtForz since 15 February. Why am I not suprised  ? |

I have tried to recompile the Ufa-miner and the rpcminer-cuda, but for various reasons it didn't work. Now I have written a very simple miner using the latest CUDA toolkit, just to see what the speed is like. Since I have written the kernel from scratch, and the program is not doing longpolling, there's some room for improvement. If somebody with a GTX680 would like to try it you can download it there: http://www.sonstiges.org/bitcoin/ICU-Miner.zipUsage: ICU-Miner.exe URL username password devicenumber gridsize blocksize (devicenumber, gridsize and blocksize are optional) For example: ICU-Miner.exe http://mining.eligius.st:8337/ 1BtVLjUkAzF9wZGHfKzzsPivgNAn4DTp1Q joshua Here's the ugly source code: http://www.sonstiges.org/bitcoin/ICU-Miner-source.zipToo bad I don't have a GTX 680. Somebody needs to try this ASAP ! |

Yeah, I need to get into the habit of reading the thread before replying  I think the issue is that most folks don't realize that they can click the little tiny word "NEW" the appears at the end of the thread title. What that does is bring you straight to the most recent message in the thread that you haven't read. So it doesn't go all the way to the end, it starts where you left off. It makes my forum-browsing life so much easier. Thank you for the helpful forum usage tips ! Any other such features that may not be obvious but highly useful ? Thanks again ! |

xfx 7970 black edition. 76.7% ASIC quality
How do you get ASIC quality in the 7xxx cards ? Thanks ! Its built into GPU-Z as far as I am aware. I meant with Linux. Just like you cannot use GPU-Z to see VRM temperatures. Has anyone tried with WINE and GPU-Z  |

Bumping this because I want some REAL results this time around. I think that people have given up on the Kepler for mining just because the kernels we have now are totally NOT optimized for it and that is why it gets only 100 MHash/s. With more kernel development I am pretty sure that this card will be a killer mining card. Maybe someone is holding back the code and mining at over 400 mhash/s Too bad I am not a coder otherwise I would have done this myself. I just find it really hard to believe a GTX 580 gets 140 mhash/s and this POS Kepler gets lower at 100 mhash/s ... Also, while we are on the subject, how is this doing for F@H : did they develop that new Kepler-optimized client that Nvidia was promising or not ? |

It's nothing like bitcoin.
the point is it will allow for the decentralization of exchanging BTC to dollars or dollars to BTC I see no mention on the website about this. Actually, after watching the video and reading the website i still have no idea what is Mintchip all about. What I see is a lot of marketing mumbo-jumbo, evolution blah blah. Yeah. I feel exactly the same. WTF is this MintChap crap all about I doubt this is better than Bitcoin ... Too much focus on Canada = I don't like these "chips". |

Interested in what you do with this BUT I doubt you will get far.
The Monte Carlo and other bitstreams is just a pathetic excuse for them to promote this as "not only a BTC miner" ( which it blatantly is ) but that it can also do other things.

Are you the MM(Mysterious Miner)?
I just noticed that 1_tx_blocks are gone(almost).
TBH this would not surprise me. It is either ArtForz or the Spanish folks in Grenada or him. Not good for BTC in any case ... |

You guys are forgetting that this isn't the only game in town. Even if he was to set up and run --lets say-- 2 Thash/s of ASICs, that isn't a monopoly or even 50%. 51% is a monopoly. You simply exclude blocks by all other miners. Making a better miner is great. Trying to monopolize the network isn't so great. Say this does launch and they get up to 2TH/s (20% of the network). If profitable there is no reason not to expand so they grow to 25%, 30%, 35% of the network. At that point it becomes asinine to NOT just expand to 51% and instantly DOUBLE the profits of investors. Hypothetically say $1M buys you 20% of the network. $2M then buys you 40% of the network but $2.6M buys you 51% of the network = 100% of the network. A private entity having 20%+ of the network is something to be concerned about. If a company is in striking distance of spending a small amount more to instantly double profits (by excluding all other miners) it is naive to think they won't. That only gets you so far. You shit all over the network, take everyone's money, and then what? Bitcoin collapses, and you don't actually have that much to show for it, since there is no more money to wring out. That isn't a long-term investment strategy, that is just fucking retarded. <tinfoil_hat> Not retarded if this guy works for the banks or for the government. ATM we don't have any guarantee that this is not the case and they are trying to use us as investors to collapse our own system / BTC at a cheaper price for the bankers / taxpayer than would be possible otherwise on their own without BitCorp raising capital for a 51% using ASIC. IMHO this technique would be very viable to kill BTC and stop all transactions and make the system worthless rather than going the economic exchange manipulation route which is quite longer and does not guarantee people losing faith. </tinfoil_hat> |

no need to worry about the future of bitcoin, eventually other companies will
come with ASIC's offers and will be selling them also
Too much faith in free market detected. I don't think anyone will be able to invest another 1+ million USD when the BitCorp ( copyrighted name Vladimir, you have to pay licensing  ) already did so and has their 10 ghash/s for $10 design and owns most of the network. |

I think this needs to be done before he gets them operational, otherwise BTC is doomed and no algo change is possible thereafter without the ASIC miner denying the change.
There is no mechanism to either enforce or deny algorithm changes, so it really doesn't matter when you do it. Miners may use their political power, but not hashing power, in this case. I myself don't think that this will ever be needed, just wanted to point out the weakness of your argument there. So how would an algo change happen ? Start a new chain ? Vote with hashing power in blocks like now ? Gavin has the last word ? Thanks for letting me know, memvola ! |

LargeCoin is NOT a real ASIC and I have not seen anything that looks like a real ASIC so far just maybe a sASIC. He says it has twice the GPU efficiency which sounds bad for everyone else not having access to this device.
Vladimir said 2-3 orders of magnitude or 100-1000 times more efficient than GPUs. Indeed. I misunderstood. Corrected. This really is bad news for BTC and decentralization.  So if he has a device for $10 that does 10 ghash/s then with with a measly amount of money he owns the network very easily. Initial costs for ASIC are high but afterwards it is very easy and cheap to replicate the design. |

This type of action unfortunately will hurt bitcoin. I can not say it will kill it, but it will not be a positive thing. And it will not be a positive thing for the investors in this company.
One of the strengths of bitcoin is that the block reward is distributed through the community. People like me spend or trade almost their entire mining proceeds in the community. Having more bitcoin (from mining) encourages me to spend more even more in the community.
While the owners of this ASIC company could act the same as I do, I really doubt that will happen. They will be turning in their bitcoin at the trading houses and depressing the value of bitcoin. They will not be helping others that accept bitcoin do business, they will just be mining and selling.
Slowly as the price/difficulty ratio gets worse, miners like me will drop out. We can not switch to FPGA as the difficulty will be so high that it will not be worth it even if electricity as free.
In the end you will have a massive centralization of bitcoin AND less economic activity. How can this be good? The price of bitcoin will drop and the INVESTORS of this company will get screwed as well.
Simply put.... we are at least two years too early for ASIC mining. Bitcoin has not grown enough for this yet. The investors will not make their money back.
Exactly what I was referring to. Nothing to do with bottom line ( my rigs are long paid off and with cheap electricity my GPUs will be humming still for quite a while ). Lots of people can buy a $200 CPU or a $850 GPU and start mining right away or a $600 FPGA but how many people will afford to buy a $500 000 ASIC farm ? This is centralization and as soon as the ASIC starts running the other miners will be phased out, ending up in him controlling about 70% or more of the network. He is not selling ASIC to the public but instead he is using investor money to get himself ( and only himself ) an ASIC farm that can totally outcompete everyone else on the network. Not sharing the ASIC design and passively attacking the network this way, who cares if it is Vladimir or the NSA because the outcome is the same : one company ruling BTC and doing as it pleases without anyone having any impact. By ASIC I think he means something that costs millions of USD to develop initially but after that this investment will give him devices like 1 ghash/s for 10W for $100 and he can use approximately 12000 of these devices at a cost of 1.2-1.5 million USD to get more than 51% of the network. LargeCoin is NOT a real ASIC and I have not seen anything that looks like a real ASIC so far just maybe a sASIC. He says it has twice the magnitude of GPU efficiency which sounds bad for everyone else not having access to this device. Phrases like " I am forming a new company that will engage into large scale mining. We have concluded a deal with subcontractors to produce a significant amount of ASIC based mining hardware (up to 2-3 orders of magnitude more power efficient and dense comparing to GPU based Bitcoin Miners). Our target is to build multi Thps (X 000 000 Mhps) bitcoin mining operation" and " We, however, have no plans to engage into manufacturing and sales of bitcoin mining hardware." tell us his real intentions in regards to this corporation. |

it is not a 51% fear. its a 30% cheap mining power fear, will become a 70% cheap and impossible to have any competition with.
small miners will quit, if its not profitable for them.
i would be more comfortable with you selling mining hardware, and thereby distribute the cheap mining power.
One cannot stop progress. GPU and FPGA's are already doomed. I am sure there will be plenty of ASIC gear on the market given time, with or without us. What needs to happen ( I think ) is we switch the algorithm as soon as the guy has paid millions for his ASICs. I think this needs to be done before he gets them operational, otherwise BTC is doomed and no algo change is possible thereafter without the ASIC miner denying the change. GPUs will be able to adapt. FPGA should be able to adapt to new algo. The only one that is screwed is the ASIC guy. If this ASIC mambo jumbo goes forward then I think BTC is as "good" as PayPal or the Bank of England. The community now has to ask itself this : "Do we really want a company effectively owning Bitcoin ?" Good luck Vladimir but I don't like where this is going and I bet I am not the only one. This centralized mining is far away from what Satoshi envisioned ( everybody with a CPU can mine ); GPUs are fine and so are FPGA but ASIC which only a millionaire can develop is too far. |

We are talking about a public company. The board of directors has a very important goal which is maximizing value and long term return on investment for the shareholders.
It does not seem feasible that we will have a monopoly on Bitcoin Mining. However, we do aim to become a major player maybe even the biggest player in this market.
Two things has changed, ASIC's have much higher density and much higher power efficiency. Therefore, unlike GPUs and FPGA's, ASIC mining has significant economies of scale and we are going to use it to our advantage.
We will be simply buying ASIC hardware from leading manufacturers and employ our scale and bargaining power to secure the best possible deal for our shareholders. It is highly unlikely (due to design of Bitcoin) that it would be beneficial for us to do any dirty tricks. The keyword here is "public company" we will be accountable to our shareholders and a significant degree of transparency is demanded by law. Fate of this company and Bitcoin will be very much intertwined.
There are discussions about placing it into "articles" (constitution of the company) that "controversial policy decisions" like which BIP to support etc. shall be brought to shareholder vote. If we do this we would effectively pass "voting power" to shareholders (those how paid for mining hardware). This is how we expect to address "51% fears". This is in a discussion stage for now and I am open for suggestions.
Of course, we will not be using any third party pools (this must be a good thing for Bitcoin).
Again, I am open for your questions and suggestions.
So you are not designing this ASIC yourself ? I don't think there is any REAL ASIC out there anyway ... You are buying from LargeCoin guys or from where |

Solo mining with 2500 mhash/s ?  Hope you are joking ... |

Why need to virtualize ?
8 is the GPU limit ...

Nothing of signifcance can be done with FPGA's besides mine.
Quite false. FPGAs are not only for mining, they can be programmed to do (almost) anything you want them to do. Indeed, products such as what Ztex sells, and the Icarus board are designed primarily as development boards. Others such as X6500 and BFL are more suited to mining only, but the chip can do many other things once it has been reprogrammed. BS. BFL and encrypted bitstream = not possible "for sure"
Also, unless they explicitly provide the special WPA cracking bitstream then they are useless.
I don't know how to make my own bitstream and I doubt many of us here do ...
BS to you. While we don't know for certain what chip is in BFL's product, that does not mean that all FPGAs are single purpose. Even if an encrypted bitstream is used, it is possible to flash the chip with a non encrypted one. The purpose of the encryption is to prevent others from copying the bitstream, NOT to prevent the chip from being used for other purposes. Excuse my ignorance. FPGA is the best thing ever. GPUs are for people that don't know any better. Anybody that is buying GPUs right now is pretty short sighted. Even with free electricity you can already see the effects of FPGA. Difficulty insanely high at relatively low prices and also I believe we will see a FPGA on 28nm that will make the GPUs obsolete just like CPU ( even with cheap electric prices ). Buy them all !!! |

I still see no resolve for my reading VRM temperatures using Linux.
I have modified this radeonvolt and it still does not appear to list the VRM temperatures but only the core temperatures.
All reference cards, too.
