     HeadLogic -->> Alice: DecommitFinalized
 ```
 
-### Incremental Commits
-
-Scenario: Alice wants to commit some `UTxO` owned by her private key to the
-Open Head. Similarly to "external" commit this means that the node can only
-prepare balance and sign the transaction but Alice still needs to add her
-signature and submit the transaction to the chain.

-    Note over HeadLogic,Chain: PROBLEM: Need to verify incUTxO on L1 as we authorize the TxIns to use (because of on-chain scripts).
