# Zero-knowledge rollup

## Definition

A zero-knowledge rollup is a Layer 2 design that uses validity proofs to demonstrate that batches of off-chain computation follow the rollup's rules.

## What it means in practice

Different ZK-rollups use different proof systems, data-availability models and compatibility layers, so the term describes a family of designs rather than one implementation.

## How this concept appears in Terenval Wallet

Terenval supports ZK-oriented L2 networks including ZKsync Era, Linea and Scroll as distinct network contexts.

**Important:** Verify the exact network and bridge route because similarly named assets can exist separately on Ethereum and a ZK-rollup.
