Wrong person/thread/board?
I am curious what are your thoughts as to Kimoto Gravity Well currently being talked up a bit by Pavel Chorbadzhiyski:
https://bitcoinfoundation.org/forum/index.php?/topic/1207-more-adaptive-way-of-adjusting-the-difficulty-is-needed/Seen in Donationcoin, Darkcoin, and Blackcoin earlier in 2013 and 2014 (not sure which implemented it first) in 2013 and 2014, there are some discussions that it could be used adaptively for bitcoin.
Anyway, let me know, there has also of course been _something related to it_ on the bitcoin-development discussion also, but maybe not exactly this, but I do not know to what extent, curious as to how you might consider that kimoto gravity well bit could be evaluated, or if it should be, in bitcoin context.
I was more interested before your edit when the question was about Kimono Gravity Wells. I've always been interested in what's under a kimono, and I could imagine gravity and a well being useful in revealing answers.
I've never been aware of any particular problems in bitcoin-land with difficulty adjustment. Alts have been attacked and have had problems, and I suppose that Bitcoin could as well under some scenarios (such as state sponsored molestation of centralized minning effort.) I've never even heard of the other coins you mention. My interest in alts is nearly nill.
In retrospect I think Bitcoin would have been much better off with quasi-random and periodically switching proof of work algorithms themselves. More significantly, I believe that the various kinds of rewards granted for supporting the system should be apportioned based on value added by diversity which would make the solution that much harder to attack. I started describing it on the paracoin deal, but haven't touched it or even looked at it for years.
Fact is though that my thoughts on the matter which I believe would have made a better currency would never have been practical in the beginning, and would never be practical to adopt in Bitcoin. So they are a pipe-dream.
I did envision sidechains shortly after I read the whitepaper as a means of scaling, but never did and do not now have the technical understanding or ability to know how to implement the two-way-peg and I'm not really sure that this rather obvious interface ever occurred to me though it should have. I gave up on Bitcoin as a viable base for a while during the satoshi-dice spam thinking that it was already mortally damaged with cruft. I've changed my mind on that and believe that if the Blockstream guys can get sidechains implemented, and if there is no more unnecessary bloat, Bitcoin is still workable and the best bet as top-dog, but a reserve-currency/exchange-currency differentiation needs to be recognized and embraced. Also, the code needs to just cease and lock with very little more work in order to preserve the confidence that it has. Vastly more development is needed, but it should occur at a different level.
Sorry to not really answer your question which was, I guess, sort of directed my way.
No, I was interested in what you had to say about it. I do have a couple kimono things around, so I might have been thinking about that, but made a mistake and put them in the text instead of kimoto, which is indeed the proper spelling for this 'kimoto gravity well' item.
I wonder if this would be adjustable enough to allow ordinary users to "dial it down" so that, in accordance with the capacity of their machines, nearly anyone could mine on some similar system such as this kimoto gravity well? When you are using BCN, the amount of resource it needs is so low you can mine it using a laptop, but there is essentially no variation (nor user direction that would indicate some adjustment needed) for adaptive-ness in such a system. It just does it as far as I can tell. But in bitcoin (BTC) it is another matter entirely, and would be very interesting to see if users with limited equipment (say, those who only have laptops or towers) could make certain adjustments and run it as we used to some years back (2010 - 2011). That would spawn a whole lot of new interest to be sure, although I have about zero idea as to how technically it might work, I certainly found the visualization (graph) here interesting:

Regardless what anyone thinks of them, in they come, and one can imagine that there will be a system in which there will eventually be zerocash, or something like it, with its own consensus system being managed potentially on a sidechain independently from bitcoin, but still being able to be exchanged for bitcoin if someone were to sit at a table and say, "hey, let's exchange this zerocash token for some bitcoin" or something to that effect. Zerocash would have its own way of ensuring no double spends. Not to say sidechains are necessary for this to work, just turning over ideas in my brain randomly, and considering some questions to e-mail the zerocash developers, who have not (yet) released the zerocash code.
