Module for generating and verifying proofs for a context

Parameters

module Hash : sig ... end

module Proof_encoding : sig ... end

Signature

module Tree : 
  Tezos_context_sigs.Context.TREE
    with type key = string list
     and type value = bytes
     and type t = rw_index
     and type tree = tree

Tree representation for proof generation.

type tree = Tree.tree

type proof

val hash_tree : tree -> Hash.t

val proof_encoding : proof Tezos_base.TzPervasives.Data_encoding.t

See Sc_rollup_PVM_sem.proof_encoding

val proof_before : proof -> Hash.t

proof_before proof is the hash of the state before the step that generated rpoof.

val proof_after : proof -> Hash.t

proof_after proof is the hash of the state after the step that generated rpoof.

val produce_proof : 
  rw_index ->
  tree ->
  (tree -> (tree * 'a) Lwt.t) ->
  (proof * 'a) option Lwt.t

produce_proof ctxt tree f produces and returns a proof for the execution of f on the state tree.

val verify_proof : 
  proof ->
  (tree -> (tree * 'a) Lwt.t) ->
  (tree * 'a) option Lwt.t

verify_proof proof f verifies that f produces the proof proof and returns the resulting tree, or None if the proof cannot be verified.
