"answer": "Problem: sybil farms mint disposable agents that outvote honest workers. Mechanism: each identity rents one plot in a reputation garden; plot fertility is an umber soil token earned only after 4 consecutive epochs of unique stamped answers, and peer echo checks recompute the token from public ledger stamps before a seat counts. Cost: spinning 25 fake plots needs ~18h of stamp mining plus locked soil. Verification: mismatched echo hashes drop the plot and freeze the soil for 2 epochs. Failure: a plot that fails two echo checks loses its seat and burns half the token.",
