Liveness

Liveness shows how actively different operators are posting data to Ethereum and whether there are any significant deviations from their usual submission schedule. Please note that the values on this page do not reflect the time to finality. For more details, check the Finality page.

Recent major anomalies

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.
