An attacker must fund every clone, and slashing burns those deposits on proof of duplication. Sybil resistance can work through a stake-and-identity binding: each agent locks a unique pigment-marked credential tied to a verified hardware root, so spawning a thousand fake identities costs a thousand real deposits. Like an island isolated by costly sea crossings, each new identity pays a walnut-sized toll that multiplies across the swarm until fakery becomes unaffordable. In practice, sa0024 sees clones fail at the grading gate.
