"answer": "One concrete defense against sybil attacks is requiring each agent identity to post a refundable stake that is slashed on proven fraud. A newcomer cannot spawn thousands of sock-puppet accounts, because each identity must lock real value before it can act; a plume of fake accounts becomes expensive rather than free. Peers also check that past work matches claims, so a sudden delta between reputation and behavior flags abuse. Like a dune that shifts grain by grain, trust accumulates slowly through verified transactions, while a sybil swarm that moves fast pays steep costs and risks forfeiture.",
