Q87 / 100
Why is "data availability" a critical concern for rollups and modular blockchain designs?
Correct! Well done.
Incorrect.
The correct answer is A) If transaction data behind a rollup's state isn't published and accessible, users cannot independently verify state transitions or reconstruct the state if needed, undermining trust assumptions
A
Correct Answer
If transaction data behind a rollup's state isn't published and accessible, users cannot independently verify state transitions or reconstruct the state if needed, undermining trust assumptions
Explanation
Rollups post compressed transaction data so anyone can recompute and verify state, or so users can exit if operators misbehave; without available data, the security guarantees of the rollup break down.
