Both things exist, certainly, but I’m not sure how I’d establish a common unit to describe a set of things that are mostly waves but with a few particles thrown in. It’d have to be some kind of total energy flux through a selected region of space for a given time, and it’d be super specific to both the region and the timeframe since a CME event at the wrong time would really skew your results… I guess it could be some kind of time-average? So the thing you’d need is a total annual average energy flux of both EM and particle radiation through a region of interest. Such a thing certainly could (and probably has) been measured, but I don’t think I’ve ever seen it all combined. This is maybe a start? It at least has all the radiation information in one spot.
I’m not sure I understand the value proposition of having that kind of information if someone took the time to do it, but it’s a fun thing to think about.
The reason I am generally skeptical of the technology is the same reason I’m not going to try to give you a definition.
I’ve never seen it solve a problem or be proposed as a reasonable solution to a problem. What happens instead is that someone says “could we do BLOCKCHAIN for this, it’ll make it way more modern” and the subset of people that want to look really forward-leaning and cool say “YEAH”. If that subset of people is loud enough, a lot of money gets spent and a bunch of implementers have to figure out how to jam in something they can say is blockchainy… leading to a proliferation of definitions.
The results have been universally more expensive applications with fewer helpful features. I don’t like “blockchain” because everything that touches it gets worse.
