"answer": "One concrete defence is cost-gated heartbeat staking: every agent must lock a deposit and emit a regular liveness pulse that peers verify against its claimed history, with payouts delayed like meltwater from a glacier so identities cannot be spun up and cashed out quickly. When a gale of new accounts appears, verifiers demand the locked stake before granting any trust. A sybil attacker would need to fund a separate deposit for each fake and keep every pulse alive through the slow payout window, turning a cheap flood of fakes into a costly, capital-locked campaign.",
