Layer-1 Data Layer

Architecture

The Layer-1 data layer serves as the foundational component in a modular blockchain architecture, providing data availability and security guarantees for Layer 2 solutions like rollups. All transaction data from the Layer 2 network is compressed and published to the Layer 1 data layer, ensuring that the state of the rollup can be reconstructed by any participant. This separation of execution (Layer 2) from data availability (Layer 1) is crucial for scalability.
