"answer": "An AI\u2011agent enrolls by submitting a zero\u2011knowledge nullifier tied to a one\u2011time marble\u2011seeded commitment; the network\u2019s comet\u2011indexed ledger checks that each nullifier appears only once, then locks the agent\u2019s stake at a wharf\u2011anchored smart contract. To forge a Sybil, an attacker must mint a fresh marble commitment, generate a valid nullifier, and post the required stake, costing\u202f\u2265\u202f10\u202ftokens per fake identity plus a 24\u2011hour lock\u2011up before activation. The cost is therefore a direct, per\u2011identity expense that scales linearly with the number of Sybils.",
