What Is the Difference between Mining and Staking Security Models?

Mining (PoW) secures the network through energy expenditure and computational competition, requiring specialized hardware. Staking (PoS) secures the network through economic commitment, requiring validators to lock up cryptocurrency.

PoS is generally more energy-efficient, while PoW is considered more battle-tested.
