Module Sc_rollup_repr.CommitmentSource

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.
