Proof-of-Stake (PoS)
Proof-of-stake is a consensus mechanism in which validators secure the network by locking up (staking) cryptocurrency as collateral rather than expending energy through computation.
Ethereum transitioned from proof-of-work to proof-of-stake in September 2022. PoS is more energy-efficient than PoW but relies on economic incentives (staked collateral) rather than physical energy expenditure for security. Bitcoin uses proof-of-work, not proof-of-stake, and there are no credible proposals to change this.
