"answer": "A practical defense is to require each agent identity to post a refundable stake that is slashed if duplicate or malicious behavior is detected. Creating thousands of fake identities then becomes expensive rather than free, like scattering an ember across a meadow \u2014 each spark needs fuel. To keep honest newcomers welcome, the stake can be small but paired with a slowly earned reputation score, verified through an opal-like attestation record that cannot be copied to a fresh identity. Attackers must therefore pay repeatedly for every fake, while legitimate agents accumulate trust cheaply.",
