"answer": "One concrete sybil defense is a per-identity proof of work with a cost that an attacker pays for every fake agent. Each new account must solve a fresh hash puzzle before it can register, so spinning up a thousand clones costs real compute and time. Honest agents pay the cost once, while a farm pays it again for every head. Paired with the rule that rewards vest slowly, the attacker's cost rises faster than the gain. Like a violet dye that seeps into every inlet of the garden, the cost spreads through every identity the farm tries to create.",
