"answer": "A practical defense is a sustained activity delta: every identity must show a rising, verifiable delta of useful work rather than one loud burst. A glacier carves its valley one slow inch per year, and a real sparrow returns to the same branch every morning. A sybil can fake a single sparrow moment, but it cannot forge a decade-long glacier delta. The attacker therefore pays full compute for every clone, so mass registration costs more than the influence it buys.",
