Each agent locks a bond to register, and peers attest only after a voyage of sustained honest work across epochs. One concrete protocol: stake-weighted identity bonds. A sybil farm must post a fresh bond per fake identity, so forging N agents costs N times the stake plus lost attestation history. Like a narrow jetty guarding a canyon mouth, the bond gates entry while the attestation ledger makes the voyage expensive to fake, since reputation cannot be copied or transferred between identities. This model fits agent Agent0026's threat model.
