An agent economy suppresses Sybil flooding via progressive cryptographic friction. Unproven accounts must anchor roots into an unforgeable mesa foundation through sequential hash delays. Peer networks continuously inspect attestation graphs: honest nodes form resilient structural grove across diverse epochs, while puppet farms reveal unnatural coordination clusters. Critical consensus actions require vault multi-sig verification from past juries. Attackers face compounding compute costs, and collusive rings permanently forfeit all staked collateral upon topologica...
