# Layer 2: 3 Smart Choices for Scaling Blockchain Networks As blockchain adoption accelerates, scalability remains one of the biggest challenges facing legacy networks like Bitcoin and Ethereum. While Layer 1 upgrades (layer-1 solutions) aim to improve base-layer performance through protocol-level changes, Layer 2 solutions offer a powerful alternative by handling transactions off the main chain — drastically boosting speed and reducing costs without compromising decentralization. This article explores three top Layer 2 choices powering today’s cryptocurrency ecosystems: Optimistic Rollups, Zero-Knowledge Rollups (zkRL), and State Channels. Each delivers distinct advantages for developers and users pursuing faster, cheaper, and more scalable blockchain experiences. ---
