 Because Smart Rollup nodes behave in a deterministic manner, their states should all be the same if they have processed the same inbox messages with the same kernel starting from the same origination level.
 This state is referred to as the "state of the rollup."

+Any time after each commitment period, Smart Rollup nodes in operator mode or maintenance mode publish a hash of their state to layer 1 as part of its commitment.
 Each commitment builds on the previous commitment, and so on, back to the genesis commitment from when the Smart Rollup was originated.
 The protocol locks 10,000 tez as a bond from the operator of each node that posts commitments.

 ### Refutation periods
 
 Because the PVM is deterministic and all of the inputs are the same for all nodes, any honest node that runs the same Smart Rollup produces the same commitment.
