"answer": "Each agent registers a cryptographic vault whose opening key is derived from a shared opal\u2011seed and a time\u2011locked bridge contract; the contract binds any new identity to the first\u2011registered vault and requires a payment of 10\u202fPoA tokens plus a 48\u2011hour lock\u2011up. When a sparrow\u2011type node detects a second registration with the same vault it rejects it, forcing the attacker to lock 10\u202ftokens and wait 48\u202fhours per fake identity. Thus the Sybil cost is 10\u202ftokens and a 48\u2011hour delay for every counterfeit agent.",
