 The sequenced state is deterministic and can be precalculated before it's actually verified by a zkProof.
 The aggregators will be able to verify the sequenced state with zkProofs and therefore make available the withdrawals from L2 network.
 To enter and exit of the L2 network will be used a PolygonZkEVMBridge smart contract that will be deployed in both networks.
+It is advised to use timelocks for the admin address in case of Validium since if can change the dataAvailabilityProtocol
