2. Proof of Stake (PoS): A Greener Alternative

Proof of Stake (PoS) offers a more energy-efficient alternative to PoW. Instead of miners racing to solve puzzles, PoS allows holders of the cryptocurrency to validate transactions based on the number of coins they own and are willing to "stake" as a commitment to the network. This approach consumes far less energy and introduces a more democratic process for transaction validation. Ethereum, the second-largest cryptocurrency, is transitioning to PoS, signaling its potential as a sustainable option for blockchain's future.
