What is Proof of Stake? How it works (Animated) + Ethereum 2.0 Upgrade!

Proof of Stake is a consensus model used by many cryptocurrencies (including Ethereum 2.0) that switches the way it picks the miners or validators that confirm blocks. Instead of letting luck pick those with the largest or fastest computers, proof of stake switches to a random selection process of those that put up a stake to validate future transactions.
