[mul-tee roh-lup ahr-ki-tec-chur]

Analogy

Like having express lanes, local lanes, and freight lanes on a highway network, each handling different traffic types but all connecting to the same road system.

Definition

A scaling paradigm where multiple rollup chains—each optimized for specific use cases—operate in parallel and interoperate via a shared or cross‑rollup messaging.

Key Points Intro

Multi‑rollup architectures distribute load and specialize functionality across rollup networks.

Key Points

Specialization: Gaming rollups, DeFi rollups, data availability rollups.

Shared security: Settlement on Ethereum or a central chain.

Cross‑rollup messaging: Enables composability between rollups.

Sequencer diversity: Independent operators per rollup for resilience.

Example

A platform runs a high‑throughput payments rollup alongside a computation‑optimized rollup for complex derivatives, both settling to .

Technical Deep Dive

Uses a : each rollup posts roots to a central coordinator contract. Cross-rollup transfers use Merkle proof based message passing and relay contracts on each rollup.

Security Warning

Fragmented liquidity across can reduce ; implement cross‑rollup bridges carefully.

Caveat

Operational complexity and coordination overhead increase with number of .
