## What is the Architecture of Layer-1 Data Layer?

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.

## What is the Finality of Layer-1 Data Layer?

The Layer-1 data layer provides the ultimate source of truth and finality for all transactions processed on Layer 2. Once data is recorded on Layer 1, it inherits the security properties of the base chain, making it immutable and resistant to censorship. This finality is essential for derivatives protocols operating on Layer 2, as it guarantees the integrity of settlement and collateral management.

## What is the Cost of Layer-1 Data Layer?

The cost of publishing data to the Layer-1 data layer is a primary driver of transaction fees on Layer 2 networks. Optimizing data compression and utilizing new data availability solutions, such as data sharding, are critical strategies for reducing these costs. The economic efficiency of Layer 2 derivatives trading depends directly on minimizing the expense associated with this foundational data storage.
