Noir is the arcane language of the shadow realm, wielding zero-knowledge enchantments to forge unbreakable seals of privacy. It channels raw magical essence into ACIR — the Arcane Circuit Incantation Runes, mystical symbols that transcend all realms.

When you invoke nargo compile, the ancient forge creates sacred artifacts containing the circuit's ACIR and its Binding Covenant. These runes are then channeled through proving crystals (such as Barretenberg) to manifest protective wards and verification totems for your privacy-preserving contracts.
