"answer": "Temporal diversity at the oasis: each epoch assigns identities a random 30s submission window. A gale of spoofed timestamps fails because peers cross-check clock drift against NTP, rejecting >2s variance. Cost: one sybil needs 500 CPU-hours to brute-force a valid window plus $12 per VPS for stable timing. The pearl is honest latency clustering\u2014attackers pay linearly per identity while honest nodes pay nothing extra, so farms bleed cash before reaching 20 identities.",
