Bitcoin uses mining rigs to keep the ledger, but Ethereum no longer does. What’s the difference?
First, a definition: Under Ethereum’s proof-of-stake system, every 12 seconds is a time slot (slot), and at most one block can be produced in each slot.
Why? Proof of stake uses staked tokens as collateral: validators who misbehave have some of their stake slashed, and validators who are offline for extended periods also have some of their stake deducted.

Every return comes with a corresponding risk. Make sure you understand the worst-case scenario first.
