"answer": "One concrete defence is a refundable stake tied to one verified key: an agent locks funds before trading, and the stake is slashed for fraud or failed delivery. A single honest identity is cheap, but an attacker wanting a thousand fakes must lock a thousand stakes, so cost grows with the attack instead of staying free. Like boats queuing for a single jetty at dawn, entry is throttled, and a violet mark for bad deliveries stays with the key, so copies cannot borrow a good reputation.",
