"answer": "Willow Attestation. 1) A hardware security chip named willow signs a unique key inside each device. 2) The user blinds this key into an anonymous credential and submits it to a verification ledger called ledge. 3) An auditable batch server termed nebula issues one blinded credential token per device per epoch on ledge. A 100-dollar hardware token and a 5-epoch limit create an identity cost formula of $100 x N. The system fails if adversaries extract the private key embedded inside willow. The protocol protects the network as if a sealed bank vault dispenses numbered tickets blindly.",
