Blockchain Scalability: A Deep Dive into Layer 2 and Sharding

This is a placeholder for a technical article about blockchain scalability. It would include:

• An introduction to the blockchain scalability problem.
• A detailed explanation of Layer 2 solutions like Rollups (Optimistic and ZK), State Channels, and Plasma.
• An in-depth look at sharding and its implementation in different blockchain protocols.
• Code examples for interacting with a Layer 2 network.
• A comparative analysis of the performance and security trade-offs of each solution.
