🧠 Web3 Knowledge Card | What is Layer 2?
As Ethereum faces congestion and soaring gas fees, Layer 2 solutions are stepping in as the heroes of scalability.
🔍 What’s Layer 2?
Layer 2 (L2) refers to off-chain networks or protocols built on top of Layer 1 (like Ethereum), which batch transactions and submit them to the mainnet, making things faster and cheaper.
⚙️ Popular L2 Projects:
Arbitrum – Optimistic Rollup, huge user base.
Optimism – Backed by Coinbase & VCs, pushing the Superchain vision.
zkSync – ZK Rollup-based, focused on privacy and speed.
Base – Coinbase’s L2, rapidly growing ecosystem.
📉 Why should you care?
Lower fees = more accessible DeFi & NFTs.
Less congestion = smoother UX.
More adoption = Web3 goes mainstream.
