Factoid – An inaccurate statement or statistic believed to be true because of broad repetition, especially if cited in the media.
I can't speak for anyone other than myself, but when I see the word "factoid" I don't immediately think it's referring to an untruth but rather a small snippet of something true about a particular issue that doesn't delve into minute details. Personally, I think it's an appropriate wording in this case, though obviously if someone not familiar with the word looks it up like you did, they might come to the wrong conclusion about the content.
"Facts" or "fact list" or "summary of facts" would be decent choices too IMO.
And yes, I'd like to see this get written, and as to the bitcoin/PoW thing, I don't see why they both can't be mentioned in the same line--like I just wrote it, because it kills two birds with one stone.
