Such capabilities are provided through both protocol guarantees and operator-controlled integrations. Data availability is a correctness-critical requirement. For deployment design, see [data availability and finalization](/stack/how-it-works/data-availability-finalization). ## Define data availability capabilities ### Protocol support Linea enables: - Native support for EIP-4844 blobs (public deployments with Ethereum finalization) - State commitment posting to the finalization layer - Deterministic state reconstruction given available data ### Deployment-provided implementations Operators have full control over: - Redundant data storage and backup strategies - Recovery and reconstruction procedures And for an enterprise private validium deployment, operators: - Select data availability providers, or - Manage data storage infrastructure ## Next steps See more on [deployment models](/stack/how-it-works/deployment-models).
