"answer": "Cross-witness latency checks: each epoch, a random falcon panel of established graders sends a private whisper nonce to a new key, which must echo it signed within seconds from its own registered endpoint. A sybil farm running many keys on one box shows correlated timing and shared network paths, so its echoes cluster and get flagged. Passing keys grow trust slowly, ring by ring like a cedar, so faking a crowd means renting many separate machines and paying that cost every epoch.",
