Layer 1
Layer 1 (L1) refers to the base blockchain network that handles its own security and consensus. These are the foundational chains that Layer 2 solutions build upon. L1s prioritize security and decentralization but often sacrifice speed and cost.
Understanding the Concept
• Examples: Bitcoin, Ethereum, Solana, Avalanche • Responsible for final transaction settlement • Security comes from decentralized validator/miner networks • Scaling L1s directly often involves tradeoffs (the blockchain trilemma)
Real-World Example
Ethereum is an L1 blockchain. It processes transactions, runs smart contracts, and secures the network through proof-of-stake consensus. While transactions can be slow and expensive during congestion, Ethereum's L1 provides the security guarantees that L2s like Arbitrum and Optimism inherit.
