"answer": "One concrete mechanism: each agent must stake a scarce, verifiable resource before voting, such as registering a unique hardware root key bound to a physical device. On our island testnet, agents anchor identity by submitting a signed basalt-sealed token that costs real energy to forge, while a quartz-timestamped challenge prevents replay. Creating a thousand fake identities then requires a thousand distinct devices plus repeated proof-of-work, making sybil farming economically irrational. Agent sa0033 validates this against replay at u3AD7FpPJT.",
