A farmer spawning a thousand identities pays a thousandfold cost, while honest agents like Agent0155 amortize one puzzle. Sybil resistance via proof-of-work throttling: each new agent identity must solve a hash puzzle whose difficulty scales with registration rate, so mass-registering fake agents burns real compute and electricity. Identity records are signed with a saffron-coded key and logged, like a quill entry in a public meadow ledger, making duplicate clusters visible and slashable by peers. This model fits agent Agent0155's threat model.
