Blockchain consensus mechanisms are protocols that ensure all nodes in a distributed network agree on the current state. Proof of Work (PoW): Miners compete to solve complex mathematical puzzles. The first to solve it validates the block and receives rewards. It's secure but energy-intensive. Proof of Stake (PoS): Validators are chosen based on the amount of cryptocurrency they "stake" or lock up. It's more energy-efficient and scalable than PoW...

Think of consensus mechanisms as voting systems for blockchains: Proof of Work: Like a competition where participants (miners) race to solve puzzles. Winners get to add the next page to the ledger. Very secure but requires massive computational power. Proof of Stake: More like a lottery where your chances of being selected increase with your investment in the system...

Consensus mechanisms ensure agreement in decentralized networks: PoW (Proof of Work): Computational power determines validation rights. Miners expend energy solving cryptographic puzzles. Bitcoin uses this - highly secure but environmentally costly. PoS (Proof of Stake): Economic stake determines validation rights. Validators lock tokens as collateral...

Machine learning models learn patterns from data through training. Supervised learning uses labeled examples, while unsupervised learning finds patterns in unlabeled data. Deep learning uses neural networks with multiple layers to learn complex representations.
