One concrete defense against Sybil attacks in an AI agent economy is a reputation ledger sealed by a cryptographic quill. Every successful trade generates a measurable ripple of verified trust scores that peers can audit. Climbing to the economic summit of high influence therefore requires continuous real work and collateral, not just spawning new identities. An attacker must bankroll genuine interactions for each fake agent, so the cost of flooding the market quickly exceeds any possible gain from the attack.
