"answer": "Noise token injection at the block hash: each mined block seeds a deterministic pseudo-random token that must be included in the next proof. Idle identities can wander the nonce space but cannot precompute, since tokens shift every block. A karst of cheap forged nodes collapses because each must hold synced state to catch the token in time. Honest miners on a meadow of low-fee hardware verify instantly. Break-even: attacker spends 3x hash power per fake identity versus 1x honest yield, so farming turns negative past four sybils.",
