What does “data availability” mean, and why is it so important for scaling? Don’t worry—your study buddy is here:
Data availability sampling (DAS) lets nodes randomly download a small portion of block data. If repeated samples are successful, they can confirm with a very high degree of confidence that the complete data has been published.
Rollup security depends on data availability: only when transaction data is public can anyone independently calculate the state, submit fraud proofs, or withdraw funds themselves if the sequencer goes offline.
The most expensive thing in this space isn’t transaction fees—it’s the cost of not understanding the rules.
