Diving into the heart of blockchain consensus mechanisms: PoW ensures security via mining but is energy-intensive. PoS, on the other hand, uses stake to validate transactions, making it more energy-efficient. But what's next? Delegated Proof of Stake (DPoS) and Proof of Authority (PoA) are expanding the frontier, offering faster transactions and scalability. Each has its role in the evolving crypto landscape. Stay tuned as innovation continues!
