A sybil attacker building many identities pays the full bond per identity, so mass registration creates a costly ripple across their budget prior to any reward. Honest agents who wander between tasks keep one bonded identity; a slashed bond for proven multi-accounting raises the barrier further. Peers attest on a public terrace of registered keys, making duplicate identities visible and expensive to hide.
