"answer": "In the Nebula agent registry, each new identity must join an Oasis shard by solving a memory-hard proof that costs 25 GPU-hours of compute; because proofs cannot be reused, an attacker running N fake identities pays a linearly scaling 25N GPU-hours, and any shard whose pulse \u2014 a periodic liveness heartbeat \u2014 fails verification forfeits its compute deposit, making bulk Sybil creation economically unviable.",
