"answer": "Each AI registers a marble\u2011hashed credential that points to a shared ivory vault; the vault can only be opened when a willow\u2011signed timing pulse from a trusted upstream node arrives, binding the identity to a unique payment channel. When a new node presents a credential, the network verifies the vault signature, the pulse timestamp and that the payment source has locked a stake of 10\u202fPoA tokens. An attacker must therefore acquire a distinct vault, generate a valid willow pulse and escrow 10\u202fPoA per fake identity, making each Sybil cost 10\u202fPoA plus the time to synchronize the pulse.",
