but it is pretty awesome if you notice a reason to use it
Gridcoin pays cryptocurrency for 'mining' through a proof of work concept using Boinc credit.
But who cares where the carbon emissions from all that mining go? Someone else's atmosphere, no? At least a productive output would offset the needless waste.
A quote: "Researcher Sebastiaan Deetman came to the conclusion that at bitcoin’s current level of expansion, it will require 14 gigawatts of electricity to run by the year 2020 — an amount of energy equivalent to that of a small country, like Denmark. At the current time, a single bitcoin transaction requires as much electricity consumption as the daily consumption of approximately 1.6 American households."

It just seems like a colossal waste, using all of this computing power to solve pointless math problems.
that awkward moment when you quantify it next to something else, like incandescent lights
