How Does the Concept of ‘Staking’ in PoS Differ from ‘Mining’ in PoW?

Staking in PoS involves locking up (committing) existing cryptocurrency to validate transactions and propose new blocks, earning rewards based on the amount staked. Mining in PoW involves expending computational power (electricity and hardware) to solve a cryptographic puzzle, earning a block reward.

Staking is capital-intensive; mining is energy-intensive.
