Imo, its not about competition, its about decentralization.[/quote]
Just some fictive questions if you or others don’t mind:
1.) What would be happen if for example a chinese Mining Company, Bitmain or any other, decides to build a mega huge GPU mining farm. Let’s say enough to cover 75% of Zcash hashrate? What would be the reaction, solution, to this? It’s of course fictive, at least i think it is, but what still interesting what would be the measures that should be taken?
2.) How much mining power has the biggest gpu farm? Maybe Genesis? In theory, would it be enough to take out 95% of the altcoins with a 51% attack that are mined with gpu’s? I’am pretty sure their hashrate power would be enough to do that. Actually such a mining farm could attack any coin as they can switch wherever they want. The big Asic farms at least are limited to their algo.
3.) Where does decentralization begin and where does it end? How it comes that me with 1x Z9 is a threat for decentralization but some gpu guy with 100 rigs isn’t?? How it comes that a bitmain mining farm with currently about 10% network share is a decentralization threat but the large gpu farms that for sure can take over 25+% of the network hashrate when switching isn’t a decentralization threat?
Wouldn’t such algo force the gpu to become a full asic itself? I mean a gpu is anyway a general purpose asic. So having an algo made that uses all gpu capabilities the algo would force the gpu to become a pure asic, of course without losing it’s general purpose abilities.
But than again, what would stop the next generation Antminer Asics to have a slightly different architecture focusing on such Algo by adding RAM, DRAM, whatever. I’am really not the tech guy, but common sense tells me that whatever a general purpose asic can, it will be possible to make a specialized asic on that which can make it just better …
Who knows if bitmain or other asic manufactores are not allready working on that ProgPow algo, the details are more or less visible to the public anyway. Someone could even add a conspiracy theorie that even such algo was developed by them tricking projects into it while there is a ready asic for it. (Not believing the later of course, just added as a conspiracy factor).
