Thanks. That makes sense. So, does proof of stake not involve mining, or does it involve it still but it's just not as energy intensive? I guess either way, from what you've described, chains using proof of stake would not only use less power, but also likely produce less waste in terms of computer components that get "worn out" from typical mining (and I guess also not contribute as much to the issue of availability of graphics cards for that matter).
Thanks for the info
