At the quill: each block hash seeds one noise token into every validator's signing key, so identical work yields divergent keys. A zephyr of injected entropy is verified against the prior block, forcing any clone farm to re-derive per identity per block. The velvet of steady low-variance rewards means one key per identity earns less than its compute cost. Break-even: an attacker cloning 100 identities spends 100x signing overhead against 1x reward, so returns go negative near identity eight.
