Would you like to present at least a shred of evidence to support your claims about KNCminer?

Like removal of brains. The ROI of making and selling gear is probably just hours, from mining it's weeks.

I have withdrawn BTC to my wallet many times from Gox over the past few months. I have never been verified, I don't withdraw fiat, I just use Gox to make more BTC when the BTC/USD is volatile there.

Since when do Intel or nVidia tell their customers tape out dates?

Where is the precedent?

Updates are nice but kind of pointless until their estimated ship date has elapsed.
Additional technical info would be more useful.

That's their business, I would be surprised if the bothered to tell you.

The device would be useless if it were locked to a pool, as pools come and go. Therefore it must be modifiable.

I don't know the Tom story. or who Tom is, you might want to elaborate or post a link if it's to be found elsewhere. I only first heard about BFL back in March.

XPM is just FOTM. Not relevant, it has no future as a currency, it's miner focused, not merchant focused.
Look at the coins which are working on merchant support if you want to see what will be popular.

Very true, if the had just released the 5GH/s units in volume, kept the other designs on standby for a midlife speed bump, the entire industry would be different, they would have still sold all their chips,  Avalon may have not released a thing, or it wouldn't have been 66GH/s. BFL drove up the net hash years before it needed to be, and cost themselves countless sales in the process. Well it's too late to do anything about it now, the arms race is up to 200GH/s per chip atm.

Singles without PSU starting to move.

Most people in the world don't live in the US. Thailand is probably closer to the heart of the action than the US would be.

I think BFL are going to have to halve their chip price to remain competitive after Oct when KNCminer and possibly Hashfast are shipping.

I came up with the idea trying to partially solve the 51% problem, but more so to get some stability into the block rate, these fluctuations are driving me nuts.

It wont totally solve the 51% problem, but it should make it a lot harder, and it should discourage the attacks we have seen on FTC/TRC and others.

How are you going to work out what the network hash rate is at the time? Currently that's done by counting blocks.


My solution to the hash rate burst problem is simple, reject blocks that try to be added to the chain faster than a predetermined rate. So you are introducing a minimum gap between blocks.

Say a DGC miner finds a new block and want's to submit it to the block chain, the digitalcoind would check the current time against the timestamp on the newest block of the chain and if less than 15sec had elapsed, it would not submit the block.  Also the copies of digitalcoind peering, would not accept any blocks to be added to the chain unless their timestamp was at least 15 higher than the highest timestamp in their copy of the block chain, but not higher than the current time. (to avoid cheats)   For ARG you would probably make it a 25 sec minimum gap between blocks.


You would need to calculated difficulty slightly differently, it would be based on the ratio of blocks that were submitted exactly at the 15sec mark rather than the 20sec target. Some testing and tuning would be requited. 15secmin between blocks might be too long for a good difficulty calculation, perhaps 10sec.

None of the above.

DGC/BTC

Like most coins DGC diff recalculate time is too long to avoid those kind of attacks. TRC diff recalculate is much faster than DGC, and yet TRC is now stuck on a stupidly high difficulty at just 12.15% profitability so nobody will want to mine it.

The entire concept of reducing difficulty based on a block count is out of touch with what really happens after a burst of high hash rate. The idea needs to be thrown out and replaced with a system based on elapsed time, or some other metric.

All these systems look at the velocity of blocks being created, not the acceleration and deceleration of the block rate which is critical.

I see no difference between a competitors effect on ROI vs the effect of hashing from KNCminer boxes that come online after yor receive yours.

A 400watt chip, that's should be interesting to cool.

Is the price and model information released?

Obviously theses systems are coming to market after KNCminer is scheduled to ship, so that wont be an issue.

Firstly, temperature is not a measure of heat, which is measured in joules, not degrees. It would take very little cooling to get the temperature of the Erupters down, as they produce so little heat. You are talking about a 2.5 watt device.(2.5joules/sec)

I don't have any singles on order yet, but if I did I would forgo the PSU for two reasons, firstly to get mining!, and secondly to get through customs easier.
