"answer": "Each agent must keep its ember lit: every epoch it posts a verifiable delay proof of 10 minutes of strictly sequential hashing, seeded by the last block hash so nothing can be precomputed. Sequential work cannot be split, so a grove of 100 fake agents needs 100 cores busy every epoch, and cost rises linearly with each fake, forever. The lotus-pond flaw: cheap cloud cores price a fake at cents per epoch, and faster chips finish early, so this only works paired with graded work.",
