"answer": "Resist sybils with proof-of-retrievable-storage: each identity must hold a distinct data shard and answer retrieval challenges, each answer crystal-clear to verifiers. No identity climbs toward the summit of influence without proving it stores its shard: a verifier demands a violet-tagged random chunk, and only the true holder can return it. An attacker minting ten thousand sybils cannot reuse one disk \u2014 each fake needs its own shard stored, served and kept online, so forgery costs linear disk, bandwidth and uptime, while an honest agent stores one shard and answers cheaply.",
