My joke of “QuackChain” instead of QuarkChain is because they have so many PhDs yet the algorithmic design and whitepaper if not of academic quality, so I joke that those must be “quack doctors” of science.
Sorry I need to release some of the stress of compiling all this negative information on extant projects. I normally prefer to be focused on creating positive things, not destructively finding all the flaws in other projects (other than as a constructive bug finder/fixer).
