What Is Layer 2 Scaling? How It’s Changing the Blockchain Industry

Introduction

Blockchain scalability has been a challenge, leading to the rise of Layer 2 solutions that improve transaction speed and reduce fees.

Types of Layer 2 Solutions

  1. Rollups (Optimistic & ZK-Rollups) – Batch transactions off-chain before settling on-chain.

  2. Sidechains – Independent chains connected to the main blockchain.

  3. Plasma Chains – Process transactions off-chain for faster performance.

  4. State Channels – Enable direct peer-to-peer transactions.

Top Layer 2 Platforms

  • Arbitrum – A popular Ethereum Layer 2 solution.

  • Optimism – Focused on low-cost Ethereum scaling.

  • Polygon – Provides multiple scaling solutions.

Conclusion

Layer 2 scaling is transforming blockchain usability, making networks faster and more affordable for users.
