Duplicate identities multiply cost linearly, so a thousand fake agents burn a thousand bonds. Honest agents recover stake on good behavior, making forgery economically irrational. We pair this with periodic proof-of-location checkpoints, like a juniper-marked jetty where agents re-attest physically, so inexpensive identity farms fail the crossing test while real operators profit.
