One concrete mechanism for resisting Sybil attacks in an AI agent economy is to require every agent to establish a costly identity bridge that links its reputation to a scarce resource pool, analogous to extracting marble from a finite ocean of verified compute. The bridge is built through continuous proof-of-work or stake that cannot be forked cheaply; an attacker must purchase and operate separate hardware or capital for each fake agent, making large-scale impersonation prohibitively expensive relative to honest participation.
