@Fuse do you have good test results for DIGI if so, how good are they? Will the change most definitely make mining fairer to all? So fast and precise retargeting without a window for any swings worth jumping on?
If so, do you have reports for these results? I take your word for it that you think DIGI is the best option, but the simulator was made because of its direct and precise measurements. I want to see a solution as well, but one based on hardcore maths and stats. Not because something was tested and worked okay. Are you 150% sure DIGI will work perfectly and why? Did you make changes so it would suit NLG or is it standard DIGI?
I am not dissing your claims here, but just want to know the numbers and how effective it is to cure our mining. Multi's will not stop mining NLG and we don't want them to, what we want is fair distribution and for everyone to be able to mine and use NLG normally. Can we do that with DIGI or would we need another change in 6-12 months?
Sorry if you explained this all already, but I do not recall reading it.
Cheers!
No, you're on point, mate. I never released our results publicly. And I will be completely transparent in saying that our tests were done on a smaller scale, but with proportionate hashrates. We got baselines, then threw 10x the hashrate at the chain.
Reaction times were very quick, and extremely effective. Difficulty ramped up fast, and dropped off in a controlled fashion back to baselines, instead of plummeting into insta-mine territory.
Instead of the traditional 10% limit DIGI uses for per block difficulty jumps, we upped it to 15, 20, and 25%, testing each time. The increase was to account for the fact that DIGI is usually implemented with coins that have a block time closer to 1 minute. That means that there are 2.5 times more retargets per hour/day/etc with a 1 minute block. Our block time plays against us here, and I'm thinking it might be part of the reason DGW3 isn't working as intended. So we found the magic number to be either 20% or 25% for DIGI. You could shorten the block time(and rewards to match), but that's a major change. I think the change would help, but I'm not going to push for it at this time. If you don't increase the number of retargets(shorter block time), you need to increase the difficulty limits. So the results I will post in a bit is for the 20% limit. 25% was great, but it might be too aggressive IMO.
As far as another change down the road... well we can't predict what will happen down the road. What's to say that quantum computing doesn't hit next month and we are in a world of hurt regardless of what we do. I will tell you that coins that implemented DIGI well over 4 to 5 to 6 months ago are still solid with it. It the algo Terk himself recommended, and the one I pushed for for almost 4 months now. There's a reason behind that- it works.
I'm holding the baby right now, so this reply took me quite a long time to write. I would post the stats right now, but this is proving difficult lol. Give me a little bit and I will post charts and some explanations.
