Key Metrics to Evaluate Layer 2 Projects
When analyzing L2 cryptocurrencies, consider:
- Transaction Speed (TPS) – Measures network efficiency.
- Gas Fees – Critical for user affordability.
- Total Value Locked (TVL) – Indicates DeFi adoption.
- Developer Activity – Reflects ecosystem growth.
| Metric | Arbitrum | Optimism | Polygon |
|-------------|----------|----------|----------|
| TPS | 40,000 | 2,000 | 7,000 |
| Avg. Fee| $0.30 | $0.50 | $0.10 |
FAQs
Q1: What is the difference between Layer 1 and Layer 2?
Layer 1 (e.g., Ethereum) is the base blockchain, while Layer 2 enhances scalability by processing transactions off-chain.
Q2: Are Layer 2 solutions secure?
Yes, most L2s inherit security from their parent chain (e.g., Ethereum) via cryptographic proofs.
