Data Availability

Rollups are L2s that periodically post state commitments to Ethereum. These commitments are validated by either Validity Proofs or are accepted optimistically and can be challenged via Fraud Proof mechanism within a certain fraud proof window. Additionally L2 data is also posted to Ethereum, hence there are no additional trust assumptions introduced.
