The data availability problem describes the challenge in blockchain scaling solutions where a layer-2 system must guarantee that all transaction data posted to it is publicly accessible and verifiable. If this data is not available, malicious actors could potentially hide invalid state transitions, preventing honest participants from reconstructing the correct chain state. This issue directly impacts the security assurances of off-chain processing. It ensures that users can always challenge incorrect operations.
Context
The data availability problem is a central concern in the design and security of optimistic rollups and other layer-2 scaling solutions. Current discussions involve various approaches to ensure data availability, such as data availability committees or sophisticated sampling techniques. Future developments are focused on developing more robust and decentralized data availability layers that can support higher transaction volumes with strong security guarantees.
