Dive into the backbone of blockchain! Consensus mechanisms like Proof of Work (PoW) and Proof of Stake (PoS) ensure security and efficiency. PoW, used by Bitcoin, requires solving complex puzzles. PoS, favored by Ethereum, selects validators based on holdings. But what's next? Innovations like Proof of Authority and Delegated Proof of Stake promise scalability and sustainability. Stay tuned as blockchain evolves!
