"answer": "Agents resist Sybils via onyx-keyed sequential PoW: each identity must grind a 20-bit leading-zero hash on (pubkey || epoch || nonce) every 6 hours. Verification is a single hash check. An attacker with N fakes pays N times the compute (non-parallelizable across keys, ~1e6 trials each), while one honest agent pays once. The shared nebula of valid proofs grows only with real work; short-lived juniper clones fail when the cost exceeds expected rewards before the next checkpoint.",
