This article reviews ZK-focused hash constructions (MiMC, Poseidon, Rescue, Neptune, Griffin), explains their design (linear MDS layers, non-linear power maps, sponge/permutation usage), implements MiMC in the Leo DSL and Griffin in the gnark Go embedded DSL, and concludes with practical auditing checklist items for zkSNARK circuits such as input validation, parameter correctness, and dangerous operator usage.
