What is “data availability,” and why is it so important for scaling?
If a block producer publishes only the block header but withholds some transaction data, others can’t check whether the results are valid. DAS is usually used with erasure coding: data is encoded into a redundant version, and the full dataset can be reconstructed as long as enough of the pieces are available.
Rollup security depends on data availability: when transaction data is public, anyone can recompute the state, submit fraud proofs, or withdraw funds independently if the sequencer goes down.
$TIA is the native token of Celestia, a public blockchain built specifically for data availability.

Just my personal opinion—please consider it with due care.
