 ### Data availability {#data-availability}
 
-As mentioned, optimistic rollups post transaction data to Ethereum as `calldata` or, post [EIP-4884,](/roadmap/danksharding/) in blobs. Since the rollup chain's execution is based on submitted transactions, anyone can use this information—anchored on Ethereum’s base layer—to execute the rollup’s state and verify the correctness of state transitions.

 [Data availability](/developers/docs/data-availability/) is critical because without access to state data, challengers cannot construct fraud proofs to dispute invalid rollup operations. With Ethereum providing data availability, the risk of rollup operators getting away with malicious acts (e.g., submitting invalid blocks) is reduced.
