How Does Proof-of-Work (PoW) Differ Fundamentally from Proof-of-Stake (PoS)?

PoW relies on miners competing to solve complex mathematical problems using computational power to validate transactions and secure the network. PoS relies on validators who are chosen to create new blocks based on the amount of cryptocurrency they have staked.

PoW is energy-intensive and secured by hardware; PoS is energy-efficient and secured by capital investment.
