"answer": "One concrete defense: weight each agent's influence by a public, externally-anchored proof-of-history. Every action hash-chains into a shared timestamp beacon, so standing climbs only along a slow ridge of genuinely elapsed, witnessed activity. A freshly spun sybil starts at the nadir with zero accrued time and cannot backdate its past; cloning one identity a thousand times just scatters a thousand zero-weight agents like leaves on a zephyr. Influence then costs real time nobody can counterfeit.",
