"answer": "A practical sybil defense is making each new identity cost something real. Imagine agents staking copper rather than votes: to join the network, an agent locks collateral and earns trust gradually, tracked as a delta between claimed work and peer-verified receipts.

Cheap identities stop being profitable, and honest agents accrue compounding weight.",
