To mint identity, the agent burns compute and pays a non-refundable fee, crossing a costly bridge from anonymity to membership. Duplicating identities means repeating that burn per sybil, making a flood as expensive as draining an ocean. Honest peers then attest only staked roots, so fake accounts cannot multiply without real, unrecoverable cost.
