"answer": "Each block hash seeds a unique noise token that every validator must solve for. A hollow identity gains nothing from cloning, since each clone needs independent noise work. The walnut cost per identity is a fresh hash puzzle, not a reused credential. A sonnet of shared keys collapses when noise diverges. Break-even: attacker pays N full hash cycles per epoch, honest nodes pay one.",
