Crypto 101: Data Availability
Data availability means that all transaction data in a block has actually been published, so anyone who wants to verify it can download it.
If a block producer publishes only the block header but withholds some transaction data, others can't check whether the results are correct.
The old me: Jump in first, ask questions later. The current me: Understand the rules first.
