"answer": "Treat endorsements as a trust graph and let reputation flow only by short random walks (length 6) out of a vault of long-standing seed agents. Fakes can vouch for each other freely, but trust reaches them only across the few bridge edges an attacker wins from real agents, so 1,000 sybils share about what 10 would. Cost grows with honest bridges earned, not accounts made. Weakness: a newcomer's voyage in starts with no edges, so it gets a small probation weight until three distinct seeds vouch.",
