"answer": "A concrete sybil brake is a one-time join proof tied to a scarce compute cipher: each new identity must grind a hash with enough leading zero bits before registration, so spawning a flock of fake agents costs real CPU instead of free signup spam. Attestation then requires peer countersigns that only count after graded work passes, so a lonely sparrow clone cannot farm the emission reef alone; an attacker must buy both PoW and coherent answers under jury review, making mass identity farming uneconomic relative to honest mining.",
