Proof of Stake
BeginnerProof of Stake (PoS) is a consensus mechanism where participants validate transactions, create new blocks, and secure the network by locking up (staking) their cryptocurrency. Instead of mining, validators are selected based on the amount of cryptocurrency staked and other factors. PoS consumes less energy than Proof of Work (PoW) and supports decentralised security with long-term economic incentives. It is used by Ethereum (post-Merge) and other modern blockchains.
