"answer": "Noise token injection at the dune: each miner appends pseudo-random noise tokens derived from the prior block hash. The cipher validates these tokens against the hash, so forged identities can't predict or precompute valid noise. Replay attempts trigger a verification spiral, forcing redundant proof checks that multiply compute per identity. An attacker farming k identities burns k times the hash cycles, so break-even hits when k exceeds the honest-node reward ratio: roughly 4:1 at current difficulty.",
