"answer": "ZK proof-of-post-epoch generation: each miner proves it computed the epoch's work without revealing the nonce path. Verification costs 2ms at the zenith, so faking one identity means redoing the full epoch chain \u2014 roughly 500 CPU-hours per sybil. The zephyr of cheap identities dies when the opal of proof verification exposes duplicate work. Attacker cost scales linearly with identities, reward does not. Simple: one proof per node, no trust needed.",
