Layer 1

A blockchain's base network, responsible for its own consensus and canonical state.

PLAIN-ENGLISH DEFINITION

In more detail

Layer 1 is the base chain that other systems may use for settlement or security. Ethereum is one example beneath many rollups. Separate L1s have separate consensus and asset histories, so the label identifies their role in a stack rather than making their security models or balances interchangeable.

How you might use it

"Our transactions run on the rollup. Ethereum is the layer 1 where its batch commitments settle."

An illustrative rollup stack submits a batch to a base network with its own consensus nodes and canonical state.
