And to a "proof of stake" model--i.e., rather than burning power to get cryptocurrency rewards, they get rewards by "staking" or putting up their own cryptocurrency and computer resources to back their copy of the blockchain. If their computer goes down and stops participating (or worse, starts to falsify the blockchain), they will get punished. If they're good actors, they'll be rewarded according to how much they have staked.

That model should use very little power.

And . . . reading that over again, it looks like gobbledygook. Sorry.
