Finality

Please note, the values on the page reflect the time required to achieve ordering finality, at which point transactions cannot be reverted or reordered. For simplicity, they do not include the overhead time to reach L1 finality, which is the same for all projects. The actionable settlement time on the L1 (that affects your ability to withdraw your funds on the L1) for these transactions may be longer. In most other cases, however, this does not apply (e.g., when transferring funds to an exchange). For more information on how finality works for L2 transactions, check our article.

#	Name	TypeType Type of this project. Determines data availability and proof system used. ZK Rollups = Validity Proofs + onchain data Optimistic Rollups = Fraud Proofs + onchain data Validiums = Validity Proofs + offchain data Optimiums = Fraud Proofs + offchain data	DA MODE The type shows whether projects are posting transaction data batches or state diffs to the L1.	Past day avg. Time to inclusion The average time it would take for an L2 transaction to be included on the L1. Please note, this is an approximate estimation and is different than Time to finality since it ignores the overhead time to reach L1 finality after L1 inclusion.	State update delay Time interval between time to inclusion and state root submission.	Execution delay Time interval between state root submission and state root finalization. For Optimistic Rollups, this usually corresponds to the challenge period, whereas for ZK Rollups, it might be added as a safety precaution.
