A commitment represents a claim about the state of the Inbox and PVM at some Inbox level.

More formally, a commitment is a claim that:

assuming the PVM and Inbox are in a state implied by predecessor
the PVM consumes number_of_messages messages tagged with inbox_level from the Inbox
the PVM advances to the state compressed_state over number_of_ticks ticks

Commitments are disjoint. The next correct commitment is a function of the previous machine state and Inbox.

number_of_messages and inbox_level can be proven/disproven by Merkle proofs on the Inbox state.

compressed_state and number_of_ticks can be proven/disproven by PVM execution, or equivalently, by an interactive proof game between conflicting parties, such that a correct executor always wins the game.

type t = V1.t = {

compressed_state : Sc_rollup_repr.State_hash.t;
inbox_level : Raw_level_repr.t;
predecessor : Hash.t;
number_of_messages : Sc_rollup_repr.Number_of_messages.t;
number_of_ticks : Sc_rollup_repr.Number_of_ticks.t;
