Zk-Rollup data availability ensures that all transaction data processed by a zero-knowledge rollup is accessible to anyone, typically by posting it to the underlying Layer 1 blockchain. This accessibility allows network participants to reconstruct the rollup’s state and verify its operations, which is crucial for users to withdraw funds or for honest parties to challenge fraudulent proofs. It forms a fundamental security property.
Context
Zk-Rollup data availability is a non-negotiable security requirement, as its absence could lead to scenarios where funds are locked or stolen without recourse. The current discussion involves optimizing the methods for posting data to Layer 1, with EIP-4844 blobs offering a significant improvement in cost efficiency. Future research and development will continue to explore innovative data availability layers and techniques to ensure robust and affordable data publication for Zk-rollups.
