1. What Is a Layer 1
Layer 1 (L1) is a base blockchain network that settles transactions and provides security — Bitcoin, Ethereum, Solana, and Cosmos are L1s. It is the foundation layer on which applications and Layer 2s build.
2. How It Works
An L1 maintains its own consensus, state, and security — validators or miners secure the network, and blocks are finalized on-chain. Applications either run directly on the L1 or settle their data/proofs to it (as rollups do). L1s compete on throughput, fees, finality, and ecosystem.
3. Why It Matters
Layer 1 design determines the base trade-offs of the entire stack: security, decentralization, and cost. Ethereum's L1 became the settlement layer for rollups; other L1s (Solana, Aptos) push high throughput natively. L1 strategy shapes which chains become the home of major applications.
4. Key Facts
- Bitcoin: PoW, ~7 TPS, maximal security focus
- Ethereum: PoS, home of DeFi and rollups
- Solana: high-throughput PoS with parallel execution
- Rollups post data/proofs to L1s for security
