First off, they both work now. They both seem to be humming along just fine, and the initial hiccups they experienced seemed to be done with. I have not paid a ton of attention to the development or discord channels of those particular forks, as we have yet another writeup coming for a new one, but they do seem to have sorted out all their issues.
They are also both gaining netspace surprisingly quickly. ChainGreen has gotten itself up over 175PiB of netspace and has seemingly solved the issues caused by their hard fork. They are behind both Flax and SpareCoin in netspace, so I do think the mislaunch caused them some issues getting users but from a pure functionality perspective they seem to be in a good place. I was able to successfully transfer 500 CGN from my test farm to my production farm and it went quickly and smoothly. Let’s see what happens on the next major Chia update.
SpareCoin seems to be a bit sketchier still. But it does work just fine. You have to download a binary zip folder with no installer and move that over to your farm to get it going. They have changed a lot more than just the name and coin symbol with the entire UI getting an overhaul over Chia. They are already up over 237PiB of netspace which is pretty incredible considering you couldnt build the software after their countdown launch.
Like ChainGreen it seems to work well enough, with no problems syncing up or getting my plots farming. No rewards yet, but that is due to the late start I got on this one compared to the others.
All in all I am very interested in where these AltChiaCoins might go. So far they have been able to overcome even serious technical challenges pretty quickly and deliver working networks.
If anyone wants to donate any weird alt-coins, I am planning on doing *something* with them for the community, once I can figure out what I could possibly do other than hold probably illegal lotteries. I am still not sure what the point of any of them will be without a solid business plan, but I do plan on making them fun at least.
