Layer 2 Solutions Explained: PoW, PoS, BFT, DAG & Beyond | Blockchain Scalability in 2025

Welcome to another deep dive into Blockchain Technology! 🌐 In this video, Explains Layer 2 Solutions and Consensus Mechanisms — from Proof-of-Work (PoW) and Proof-of-Stake (PoS) to BFT, DAGs, and modern hybrid protocols like Solana’s PoH and Avalanche consensus. Whether you’re a beginner trying to understand scalability or an advanced learner exploring Layer 2 design, this tutorial is for you. We break down concepts with clear examples, visual diagrams, and comparisons — including Ethereum’s Dencun upgrade, Bitcoin Lightning, Arbitrum, Optimism, and zkSync. What You’ll Learn What is the Blockchain Scalability Trilemma Role of Layer 2 Solutions in solving it Difference between PoW vs PoS Modern consensus designs: BFT, DAG, PoH, Narwhal Rollups (Optimistic & ZK) and their architecture 2025 trends in L2 scaling, data availability, and modular chains Key Takeaways PoW = security & decentralization PoS = scalability & efficiency L2 = faster, cheaper, inherits L1 security Modern Consensus = instant finality & high TPS Future = Modular + AI + ZK + Shared Sequencers 🔗 Resources GitHub (Code & Diagrams): https://github.com/codebyankita Medium Articles:   / ankitacode11   LinkedIn:   / ankita-virani-4bb478282
