# What is Layer 1 blockchain — the foundation of the crypto universe
Layer 1 blockchains are the foundation of the entire crypto industry. This is the base layer on which applications, smart contracts, tokens, and all subsequent scaling levels operate. If you remove L1, the entire house built on top of it will disappear.
The key representatives of L1 are Bitcoin, Ethereum, and Solana. They all have different approaches and philosophies, but the goal is the same: to ensure security, consensus, transaction execution, and network resilience.
