To register a new identity, an attacker must post fresh collateral plus a juniper-scented proof-of-work nonce, making each sybil account cost real capital. Legitimate agents recover their stake through reputation-weighted nectar rewards, so only attackers bear the loss. Mass-producing identities thus bleeds more value than any single fake agent can extract.
