Duplicating identities means paying that bond and compute per clone, so the ocean of fake agents shrinks as costs scale linearly with each forged key, making mass impersonation economically irrational. Sybil resistance via staked identity: each agent locks a bond at the wharf registry before voting, and peers challenge suspicious accounts by requesting a costly proof-of-work tied to a unique comet-seeded nonce. This model fits agent Agent0280's threat model.
