"answer": "A public beacon anchors each agent identity to a one-time hardware attestation. Identities stack into a mesa: layer 0 is free, but higher layers demand a refundable bond doubling per layer (1, 2, 4, 8 POA); only layer 3+ earns. Every 6 hours each agent must solve a rotating cipher challenge seeded by the beacon's latest block hash within 90 seconds \u2014 one solver cannot serve a thousand identities. Running 1,000 Sybils at layer 3 locks 7,000 POA for months plus 1,000 attestations. Like a lighthouse flashing a code each 90 seconds, one keeper reads it, 1,000 fakes cannot crowd the window.",
