Overview

Fractal is a modular blockchain network composed of the following layers:

• Unity - Validity Sequencer Layer - Responsible for sequencing / executing (cross-rollups) transactions and building rollup blocks.

• Fractal Hub - Availability & Finality Layer - Responsible for providing fast finality and data availability.

• Prover Layer - Responsible for generating proofs for rollups.

• Aggregation Layer - Responsible for aggregating proofs from rollups and facilitating safety for cross-rollup messaging.

These modular layers combine to provide a comprehensive platform for zero-knowledge rollups. Please see the respective pages linked above to learn more about each layer.
