Layer 1
The base blockchain layer where transactions are recorded and validated directly on-chain.
A Layer 1 is the foundation blockchain that processes and records transactions directly on its own network.
It’s the main chain — the place where blocks, validators, and consensus actually live.
Examples include Bitcoin, Ethereum, Solana, Cardano, and Avalanche.
Every Layer 1 has its own rules, fees, and security model.
Why it matters
- It’s where final settlement happens — the source of truth.
- Determines how fast and secure a network is.
- Other systems (like Layer 2s) depend on it for validation.
How it works
Layer 1 blockchains reach agreement through consensus mechanisms,
such as Proof of Work (PoW) or Proof of Stake (PoS).
These define who adds the next block and earns rewards.
💡 Lanzo Tip
When researching projects, always check which Layer 1 they’re built on.
It affects fees, speed, and ecosystem compatibility —
for example, an Ethereum-based app can’t run on Solana.
