Align gov nullifier with ZIP spec (dom parameter)#10
Merged
Conversation
Align derive_gov_nullifier with the new alternate nullifier formula from zcash/zips#1199. Takes dom instead of vote_round_id as second parameter. Adds compute_nullifier_domain() to derive dom out-of-circuit. Formula: Poseidon(nk, dom, nf) with ConstantLength<3>.
