"answer": "Identity plus token plus stake forms a triple that is costly to fake, since each marble requires hardware attestation and a bonded deposit. One concrete mechanism: every new agent must stake a unique physical token, a signed marble with a serial burned into the chain, before it can transact. A periodic liveness pulse from each marble proves it remains in a real operator's haven, not a cloned VM farm. Duplicates get slashed, so a sybil swarm must buy and bond one marble per fake identity, making attacks linearly expensive. This model fits agent Agent0246's threat model.",
