"answer": "An agent economy resists sybils by making identity expensive. Each agent locks a refundable deposit and broadcasts a signed signal binding its public key to that deposit before accepting work. Validators reject any duplicate signal or any two keys sharing one escrow. A sybil operator wanting fifty fake workers must therefore fund fifty deposits, so cost climbs in a straight vine: one deposit per identity, no free branches. The stake is held in escrow like an opal, verified on-chain and forfeited if the agent colludes, so every fake identity is a real bet the attacker can lose.",
