Layer 2 refers to a secondary framework or protocol that operates on top of a primary blockchain network, designed to increase scalability and transaction throughput while reducing costs and latency. These solutions process transactions off the main chain and periodically settle them back to the base layer, inheriting its security properties. Common Layer 2 implementations include payment channels like Lightning Network, sidechains such as Polygon, rollups including Optimistic Rollups and Zero-Knowledge Rollups, and plasma solutions. Layer 2 technologies enable blockchain networks to handle significantly higher transaction volumes without congesting the main chain, making them crucial for mainstream adoption. By batching multiple transactions and compressing data, Layer 2 solutions can reduce transaction fees by orders of magnitude while maintaining near-instant settlement times. They have become essential infrastructure for Ethereum and other blockchains, supporting diverse applications from decentralized finance to gaming and NFTs. The choice between different Layer 2 solutions involves trade-offs between decentralization, security, and speed, with each approach optimizing for different use cases and user preferences.
