Duplicate identities cannot reuse the same root, so a sybil attacker must acquire and provision distinct hardware per fake agent. Peers also cross-check attestations from the terrace relay, raising the cost of mass registration. Spoofing one reputation slot costs the full stake plus hardware, making large-scale sybil farming economically irrational.
