Doing a home made ASIC is not a trivial.

Not just not trivial, totally impossible. You can design an ASIC at home, but to produce it you need a multi billion dollar factory. If you bring enough dollars, and buy enough units, the companies owning those factories will happily produce them for you. That's what's happening with Avalon and BFL.

It's cool how most of the users have a trillion posts, but so few actually know and have been in a semiconductor manufacturing facility.

To design an ASIC you need a software which is expensive and you have to be really good specialist. It might not work otherwise.

And you need MILLIONS of dollars worth of equipment, not billions.

Companies, would not produce these miners because they could be adjusted for cellphone interception. The cellphone code is just 56bit. If you have a rainbow table it goes down to 36. You can imagine how easy would it be to get 10 of these devices and then decrypt conversations in real time.

And there is another issue - banks are not going to be happy that big companies are promoting a decentralized currency. It's just the way they work.

By the time most private people get their ASIC rigs the increase in 'difficulty level' from mining will be so high as to make most close to break-even.




 

People, higher difficulty level = higher price. If the difficulty level is 1000 times bigger, but 1 coin is worth 100000$ what does it matter?

It's not impossible to reach 100000$. Question is - if the exchange facilities will be able to handle it.

To design an ASIC you need a software which is expensive and you have to be really good specialist. It might not work otherwise.

In principle you can do the design for FPGA first and then reuse it unchanged for an ASIC. I think you can do that with just open source software. You do probably need an EE graduate with a specialisation in microelectronics.

And you need MILLIONS of dollars worth of equipment, not billions.

Depends on the size of the plant I guess, which would likely be small since you don't need to produce hundreds of millions of units. But fabs costs more than a billion dollars.

Companies, would not produce these miners because they could be adjusted for cellphone interception. The cellphone code is just 56bit. If you have a rainbow table it goes down to 36. You can imagine how easy would it be to get 10 of these devices and then decrypt conversations in real time.

By that logic Avalon, ASICMiner and BFL could not have found suppliers.

That hasn't stopped the three ASIC mining companies.

ROI is not a verb, the term you're looking for is 'to break even'.

By "companies" I mean established enterprises with good specialists and production base. Not some from-home "industrialists" who never had a job before, but have decided to create something big with other people's money such as BFL and the others.

For now, only Avalon has shipped ANY product. No one else.


Big companies are companies who know what they're doing. Sapphieretech for instance. Companies such as theirs would be able to manufacture a good priced product in great quantities. Not BFL.

BFL are fraudsters by definition. Even if they ship they will probably delay all their "batches".

That's not a serious way to do it. No real business has 100% assurance of purchase. That's called communism. And I hate communism.

And an open source software could not be used in microchip design. Pirated software - yes. Open source - no. At least not for VLSI chips.
