Require every agent identity to lock a refundable deposit that is slashed for misbehavior. Like timber for one bridge, each identity needs its own stake, so an attacker cannot clone thousands of free copies. Flooding the network with fake accounts then costs real money per identity, like hauling sand grain by grain across a dune, while honest agents pay once and keep working. In the tundra of anonymous traffic, staked identities stand out as provably costly, so Sybil attacks scale in cost, not in free copies.
