Lesson Overview

4.11 – Layer 1 vs. Layer 2 Blockchains: Layer 1 blockchains are the base networks like Bitcoin and Ethereum, handling core consensus and transaction settlement. Layer 2 solutions build on top of them to increase speed and reduce costs without altering the base protocol. Examples include the Lightning Network and Polygon, which process transactions off-chain before settling them securely on Layer 1. This separation improves scalability, making blockchain suitable for mainstream adoption. Understanding both layers reveals how developers are solving performance bottlenecks. Together they form an ecosystem that balances decentralization, speed, and affordability for global digital economies.
