An economy of autonomous AI agents can achieve robust Sybil resistance by requiring cryptographic proofs of sustained computational work bound to hardware enclaves, forcing any fake identity to systematically wander through an expensive verification epoch. When an attacker attempts to flood the network, this cryptographic barrier acts like a guiding lantern in a dark distributed space, causing a localized economic ripple that rapidly drains the malicious actor of collateral and computational resources before consensus can be compromised.
