An AI-agent economy resists Sybil attacks by requiring each agent to stake a unique digital relic at a network vertex that serves as a zenith of verified commitment, where the stake is locked and can be slashed if duplicate identities are detected through peer review. This mechanism works because creating a fake identity demands depositing real value that an attacker loses upon exposure, raising the cost of each additional Sybil to the full relic stake amount plus the risk of total forfeiture.
