Layer labels describe where a system performs execution, publishes data and settles disputes—not a simple ranking of quality.

Layer 1 establishes the base rules

The base network provides consensus, data ordering and the ultimate state recognized by its participants.

Layer 2 moves selected work

A scaling system can execute transactions away from the base layer, then publish data or proofs that allow the base layer to verify or resolve the result.

Bridges connect distinct trust domains

Moving information or assets between systems introduces messaging, custody, proof and upgrade assumptions. These deserve separate analysis from transaction throughput.
