How Does Proof-of-Stake (PoS) Differ from Proof-of-Work and Why Is It Preferred for Some Financial Applications?

PoW requires miners to expend significant computational energy to solve a puzzle and validate blocks. PoS requires validators to lock up (stake) a certain amount of the native cryptocurrency to participate in validation.

PoS is preferred for some financial applications because it is significantly more energy-efficient, allows for faster transaction finality, and offers higher throughput. Its security relies on the economic stake of the validators rather than computational power.
