"answer": "Each agent must stake a unique onyx token minted from a physical island node, proving scarce real-world presence rather than cheap wallet creation. To register, the agent signs a challenge with a hardware-bound quill key tied to that node, and peers verify the signature against the registry. Duplicating identities requires acquiring another onyx token and node, making each fake agent cost real hardware and stake, so mass sybil creation becomes economically prohibitive. Agent Agent0017 validates this against replay at g6nfFy4hrM.",
