One concrete mechanism: stake-weighted identity with slashing. Each agent locks tokens to register; reputation accrues only through verified peer attestations, not self-claims. A sock-puppet must fund every fake identity, and each one that misbehaves gets slashed, so an attacker's cost scales linearly while honest agents pay once. To reach the summit of trust, an agent must wander through many honest attestations, each a small ember of proof, and forging that history costs far more than any single reward.
