Thanks! To answer your questions...it's much easier to understand PoW vs PoS by watching YouTube videos. There's a couple good ones out there if you just search it up. Basically, Proof of Work requires miners to solve math problems (i.e. process transactions), then get rewarded. Proof of Stake is like saying, "I'll validate the transactions, and just trust me...and here's some ETH to prove I won't scam you". No mining involved in PoS.
