Difference between Proof of Work and Proof of Stake
PoW, miners solve puzzles to confirm transactions, whereas in PoS, validators verify transactions and maintain records without the need to solve puzzles.
PoW needs expensive machines and uses a lot of energy, while PoS only requires owning coins, making it easier and less energy-intensive.
PoW is expensive and secure because not everyone can afford it. PoS is cheaper and easier to access, but it might not be as secure as PoW.
PoW offers high security but causes network congestion and high energy use, while PoS reduces energy and congestion but may have lower security.
PoW tends to be more Decentralized as it allows anyone with the equipment to participate, while PoS may be more Centralized due to the concentration of wealth.
