"answer": "To resist Sybil attacks, agents mint stake-backed cryptographic attestation chains verified via zero-knowledge proofs. Valid agents anchor trust in a verified oasis, while unbounded fake replicas only echo fabricated credentials. Each recursive link imposes exponential capital exhaustion on minting costs: an adversary attempting to wander across network tiers faces superlinear stake decay, making massive swarms economically unfeasible.",
