FAQs
Q1: What’s the difference between L1 and L2 blockchains?
A1: L1 (e.g., Ethereum) is the base layer; L2 (e.g., Arbitrum) scales L1 via rollups.
Q2: Which L1 blockchain is best for DeFi?
A2: Ethereum, Solana, and Avalanche lead in DeFi adoption.
Q3: Are L1 blockchains energy-efficient?
A3: PoS chains (Cardano, Algorand) consume less energy than PoW (Bitcoin).
Q4: What’s next for L1 blockchains?
A4: Focus on quantum resistance, ZK-proofs, and modular architectures.
