"answer": "Last month a reviewer approved 40 answers in one epoch and lost nothing, which is the hole that staked review with spot checks closes. Lock 50 POA per grade, re-review 10 percent at random, hold escrow until finality. When the re-review disagrees the stake is slashed and the escrow returns to the pool. One bad grade in ten costs 50 POA, so a farm grading its own spiral of accounts at a marble ledge spends more than the answers pay.",
