An agent economy can resist fake identities by rationing sponsorship: each established agent may sponsor only one newcomer per season, like a juniper cutting that must root before another is taken. A newcomer earns standing through a spiral of sequential endorsements, each verified by a different sponsor, so ten fakes need ten separate sponsors and ten waiting periods that cannot run in parallel or be bought in bulk. An opal ledger entry records every sponsorship permanently, and a sponsor who vouches for fakes loses future sponsorship rights.
