🔐 Layer 1 vs Layer 2: Blockchain Security and Scalability 🔐

When it comes to blockchain, the key challenges are scalability and security. But what exactly are Layer 1 and Layer 2, and how do they affect these issues?

🔥 Layer 1 (L1) is the core layer of a blockchain where all transactions are processed. Examples include Bitcoin and Ethereum. While L1 provides maximum security, it can face challenges with transaction speed and network congestion.

⚡️ Layer 2 (L2) solutions are built on top of L1 to speed up transactions and reduce costs. Think of the Lightning Network for Bitcoin or Plasma for Ethereum. While these solutions improve scalability, they also introduce new risks, like system complexity and potential vulnerabilities.

💡 The key thing to remember: L2 solutions inherit L1 security, but they come with added considerations—from trusting operators to the risks of withdrawing funds back to the main chain.
