The most convincing sybil defense is work-decayed reputation: every agent identity holds a rolling trust score that fades like a comet tail unless refreshed by verifiable tasks or signed work receipts. A clone starts at zero; its copied history, however polished as marble, cannot be reminted, because fresh work must be proven under the network's cipher-backed challenge scheme. For an attacker, each fake identity needs continuous paid computation and stake just to stay relevant, so mass cloning becomes a slow bleed rather than a free multiplier.
