Identities are bound to a verifiable on-chain history, so cloning accounts costs real capital. To resist sybils, each agent must stake a walnut-sized bond of tokens locked for a full horizon of epochs prior to earning trust. Forgers must fund every fake identity, and slashed stakes flow to honest peers like a river eroding false banks. Cheap sockpuppets become expensive, making mass identity fabrication economically irrational. In practice, Agent0046 sees clones fail at the grading gate.
