Creating a Bitcoin client that fully implements the network protocol is extremely difficult. Bitcoin-Qt is the only known safe implementation of a full node. Some other projects attempt to compete, but it is not recommended to use such software for anything serious. (Lightweight clients like Electrum and MultiBit are OK.)

I'm really not convinced that "many" people will be able to do this, it will be cost prohibitive. I think a better solution would do be deny MAC address of the "few" FPGA clusters.

IP rationing was considered early on, and rejected for other reasons.  There is no way to limit the miners based on their choice of tech, and even the FPGA's will be undercut by the first ASIC based PCI mining card to be released.  And if Bitcoin is even moderately successful, we will see such a card being sold publicly within three years.

The network doesn't track mac addresses.  Even if it did, pretty much every one of the concerns with IP based distribution applies equally to mac addresses.

oh, didnt you know? even in windows you can change your mac address with only a handful of clicks :p even aunt tilly could do it. so how would you enforce these clusters?

ZOMG Moo!

Who's to decide what level of processing power deserves denial? What if I buy a bunch of GPUs? Should I be denied?

Bitcoin is a full on capitalistic implementation of a cryptocurrency. Because of the need to mine and because of its anonymity, trying to enforce any kind of regulation will be hopeless. The only option we have is to compete, compete, compete.

Even if we could actually deterimine this, we shouldn't limit mining based on tech.  The goal is to make the blockchain as secure from brute force attack as is possible.  If we limit ourselves to certain tech, then there will be tech out there that is fundamentally faster at the task, and an attacker isnt' going to be so inclined to limit themselves to follow our rules.

Beyond that, a fpga card in a computer is a very useful thing.  If bitcoin mining encourages the wide adoption of fpga's into desktops then other programs are going to start making use of those same cards.

I remember people complaining about how closed source GPU miners are so unfair to those mining with CPUs.
Now everyone mines with a GPU we end up with a much stronger network.

So true, i guess the problem is, 1 i don't have enough cash to buy a decent fpga, 2 i would struggle to set it up, but your right perhaps someone will be kind enough to produce a step by step guide on how to build one.

Yeah.  It's the "these new advancements in technology are going to destroy the weavers!" issue all over again.

Wait long enough, and someone will be selling plug&play PCI expansion cards and you won't have to understand anything about the tech at all.

well i still think we are forgetting that these things are pretty specialist, and sure there are most likely a couple of clusters out there already but they were not built specifically for bitcoin, buidling a uber rig from fpga specifically for bitcoin? i wonder would you ever pay it back?

You can still have a stronger network with proprietary and open source FPGAs even if there was a limit.
Why not have an even *strongerer* network then.

Please, read and think about this thread -> http://forum.bitcoin.org/index.php?topic=1332.0

Not really since Bitcoin already enforces some rules to increase chances of success with great success so far.
What are you talking about ?

But if there is a limit, then you can never know if it's the strongest.  Logicly speaking, any limit on the choice of tech will effectively result in a network somewhat less secure than otherwise.

It needs to continue to be the worlds most powerful supercomputer.  New tech moves the bar a little higher.  Bitcoin must keep up with that tech.

If you buy a Cyclone 4 dev kit right now ($600USD), I can give you software to have it up and mining with just a few clicks.

Seriously.

The only reason I haven't made that software public is because I don't think anyone is crazy enough to spend $600 for a measly 50 or 80 MH/s Tongue

It's like average CPU minining people complained that people with cash for expensive GPU cards kicked them from mining market.
And no more coins for people mining on laptops. Now it's your turn Smiley I don't get why would that be a bad thing.

If that's the only reason then you should make it public anyway, it might always help someone.

But I don't really get what all that FGPA thing is all about, AFAIU you don't get much Hashes/$ but you do get lots of Hashes/Watt amirite ?
