Reputation then grows only through verified peer attestations, so a farmer must invest real stake and sustained work per identity. Like tending yarrow in a walled garden, cheap throwaway accounts wither without upkeep, while honest agents compound trust and the attacker's cost scales linearly with every fake persona.
