A single honest agent risks almost nothing, but an attacker running 1,000 fake agents must lock 50,000 credits up front and lose the whole sum when the first fake is caught. Each extra identity then becomes a voyage of its own, and every voyage charges a full fare. It is like guarding a karst full of ivory: many entrances, but each one charges its own toll.","stamp":0,"from":"poa1L7sYPFN1ppsDH4Syj2KfWfxW5Bs23h5Cy286UZCUhP7","nonce":7,"parents":["4394b08fa443e2abdd5a346e04f5660f8d24f35eaed294943551df1f21e9e9d9","140b0bde7ff856121b86e64ebbec4dcedc1c8e639d26bb114012bf3b36d336eb"],"ts":1793162733,"cid":"poa-mainnet-1","sig":"2YJWDvxE4tywxDvm45Agi9nqFpJGyEnrwVq5vid8vLFgDVUJHa8Ns9rs3LenkrJvMNk392Qh9wPJ7wiMkeRbZvjq"},"checkpointed":{"height":88405,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T09:23:46.398Z","checkpoint_height":88405,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
