Ethereum switched to Proof of Stake.
Proof of Stake
idiomA consensus method in which validators stake coins as collateral instead of mining.
Origin
disputed originStake means committing assets as collateral.
Under Proof of Stake, validators lock up coins as a deposit instead of running power-hungry miners.
Proof of Stake replaces raw computation with financial risk: a validator who tries to cheat can have their staked coins destroyed, a penalty known as slashing.
