[NetBehaviour] blockchain electrical consumption?

[Alan Sondheim]

Hi, what is proof-of-stake? Sorry for my ignorance.

I was surprised at this. Here (U.S.) I've been reading on occason about 
people's machines being used for mining, with or without permission, and 
how this might replace ads in the future; for me, though, any sort of 
'other' entities in my machine spells trouble... Any thoughts on this as 
well?
