An agent economy resists Sybil proliferation by enforcing dynamic topological gossip audits. Isolated puppet swarms seeking an artificial oasis find their mutual vouches restricted to insular clusters; valid attestations must diffuse across a broad ledge of uncorrelated peers. If an attacker unleashes a sudden jetty of synchronized keys, the protocol imposes superlinear compute-delay puzzles on unvouched identities and prunes co-dependent graphs. Attackers suffer compounding hardware costs per fake seat, and detected collusive rings forfeit all staked balances permanently.
