 The Holocene upgrade is a protocol upgrade. Learn more about it in the [Holocene notice page](https://docs.optimism.io/notices/holocene-changes). This guide shows you how to take your OP Stack chain from the L2 Output Oracle System to a permissioned Fault Proof System contract version associated with the Holocene upgrade. 
 
 After upgrading to OP Stack contracts v1.8.0 and enabling permissioned fault proofs, all pending (unfinalized) withdrawal proofs created on L1 are invalidated. This means that withdrawals must be manually reproven by users after the upgrade; the process is not automatic.

 ### 6. Verify outputs
 
 Now you have the calldata that can be executed onchain to perform the L1 contract upgrade. You should simulate this upgrade and make sure the changes are expected. You can reference the validation files of previously executed upgrade tasks in the [superchain-ops repo](https://github.com/ethereum-optimism/superchain-ops/blob/main/tasks/eth/022-holocene-fp-upgrade/NestedSignFromJson.s.sol) to see what the expected changes are. Once you're confident the state changes are expected, you can sign and execute the upgrade.
