Description

Partial fulfillment for #4395:

  • Added hashing API to the MMR by virtue of forcing the hashing type to be D: Digest + DomainDigest instead of only D: Digest at the lower level MMR methods and functions.
  • base_layer/mmr/src/common.rs
  • base_layer/mmr/src/merkle_mountain_range.rs
  • base_layer/mmr/src/merkle_proof.rs
  • base_layer/mmr/src/mutable_mmr.rs

Fixed cucumber function const getTransactionOutputHash = function (output)

Motivation and Context

Domain separated hashing as per the tari_crypto hashing API is needed for the MMR.

How Has This Been Tested?

  • Passed unit tests
  • Passed cucumber tests
