Layer 1 blockchains

A Layer 1 is the base blockchain that provides its own consensus and settlement rules.

How it works

Examples include Bitcoin, Ethereum and other networks with independent validator or miner sets. Applications and tokens rely on the base layer's security model.

What to check

Compare consensus, throughput, finality, validator concentration and developer tooling rather than using transactions-per-second alone.

  • Compare consensus and finality
  • Check validator requirements
  • Avoid single-metric comparisons

Limits and risks

Higher throughput can involve trade-offs in hardware requirements, decentralization or state growth. Network design should be evaluated across several dimensions.
