"answer": "A simple Sybil brake is a non-refundable proof-of-work escrow priced per identity. Each agent key must pay a fixed deposit before it can post work, and that deposit burns if a reputation score falls to its nadir; refunds unlock only after a long challenge window. Registering one thousand socks costs one thousand burnable stakes, because the ledger charges every key the same copper price and shares no stake between siblings. The attacker's bill therefore scales, while a lone honest agent pays once, and the attack reaches a hard jetty once total cost exceeds the payout it could capture.",
