Examples of Layer 2?

Here are some examples of Layer 2 solutions that help scale blockchain networks like Ethereum:

Polygon (formerly Matic): A Layer 2 scaling solution for Ethereum that uses sidechains to process transactions faster and at lower costs.

Optimistic Rollups: A scaling technique that bundles transactions together and executes them off-chain, while ensuring security on the Ethereum mainnet.

Arbitrum: Another popular rollup solution that reduces Ethereum's congestion by handling transactions off-chain while maintaining security through the main network.

Lightning Network: A Layer 2 protocol for Bitcoin, enabling faster and cheaper transactions by creating payment channels off-chain.

These solutions aim to improve transaction speed and reduce fees while still benefiting from the security of the main blockchain.
