 As inputs, this operation will accept the proof generation or verification initialization result, as outputted by the `ProofInit` ((#proof-initialization)) or `ProofVerifyInit` ((#proof-verification-initialization)) operations (`init_res`). It will additionally accept the set of scalars representing the messages the Prover disclosed (`disclosed_messages`) as well as the list of indexes those messages had in the vector of signed messages (`disclosed_indexes`), together with the presentation header (`ph`).
 
+At a high level, the challenge will be calculated as the digest (using `hash_to_scalar` defined in (#hash-to-scalar), to map it to a scalar value) of the following values:
+
+- The total number of disclosed messages `R`.
+- Each index in the `disclosed_indexes` list, followed by the corresponding disclosed message (i.e., if `disclosed_indexes = [i1, i2]` and `disclosed_messages = [msg_i1, msg_i2]`, the input to the challenge digest, after `R`, will include `i1 || msg_i1 || i2 || msg_i2`).
+- The points `Abar, Bbar, D, T1, T2` and the `domain` scalar, calculated during the proof initialization phase of `CoreProofGen` (see (#coreproofgen)).
+- The inputted presentation header (`ph`) values.

 This operation makes use of the `serialize` function, defined in (#serialize).
