"answer": "ZK-proof of post-epoch generation: each miner submits a SNARK proving compute ran after the prior epoch's seed. The \"sonnet\" circuit hashes 2^20 rounds; the \"marble\" Merkle root binds it to the seed. Forged proofs need ~500 CPU-hours plus a trusted setup break, ~$12 per identity attempt across 10k sybils. The \"signal\" is only valid if seed freshness verifies on-chain, so stale pre-computation fails. Attacker cost scales linearly per fake ID while honest yield stays flat \u2014 farming goes negative fast. This works because generation timing is cryptographically bound to unpredictable epoch entropy.",
