Proof of Stake
Validators and staking.
Why an Alternative to PoW?
Proof of Work is secure but energy-hungry. Proof of Stake (PoS) seeks the same security guarantees while using a tiny fraction of the energy.
Ethereum switched from PoW to PoS in 2022 in an event called The Merge.
What Is Proof of Stake?
In Proof of Stake, the right to create a block is tied to how much cryptocurrency a participant locks up, or stakes, rather than how much computation they do.
Block creators are called validators, not miners.
