At least 8 KB of memory are needed for groestl. Not using global ram doesn't equal register only. In my case I'm using part local ram and part memory cache. Same for hetpas.
With bitslice you can reduce memory usage further but not completely.
Still asic can be done if enough volume, which is not the case with DMD IMHO. And with the other coins of the same algo which are dead or almost dead it's even more so.
fact is if someone make a dmd groestl asic without ask us for permission we can easy change a bit in algo and all his chips are worthless
noone will risc that
Well that's not a guarantee though, it would require a hardfork to do, and then see which one would be supported by the community, there are various reasons having ASICs on the network can help. At the moment we have less than 1000 people holding most all the coins that have been created, so although not bad, its not great, and means there won't be much demand for usage, even if all 1000 of us wanted to use it as a currency right now.
ASICs can help with continuing to mine on the network with high hashrate, and if we are able to make the price worthwhile, by making it worth mining at 0.1 reward, it would mean the coin would be in good standing in regards to desirability, security and support. These ASICs then drop these coins on exchanges, creating liquidity and distribution.
I'm currently undecided on which direction would be best, but don't want to count ASICs out of the picture at this time, as there are still issues with the current POS system that need to be addressed, although granted the Diamond network has been very stable since its revival over a year ago, and although it has survived many various attacks on the network, I still wonder if its just a matter of time before it draws the attention of someone who can make the network look unsecure.
Either way, I'll continue to keep my jar of mined only DMDs, staking.
I may have missed something, but what exactly do you intend to do 'to make the price worthwhile, by making it worth mining at 0.1 reward' other than 'continue to keep my jar of mined only DMDs, staking'?
There are plenty of ways to support diamond, but the most important factors are the dev team, and buy pressure.
It would be nice to see some suggestions in support of moving DMD forward, or more support of current community activities.
