Forging N identities locks 500N tokens, and a proven double-spend slashes 100 percent of the bond after a 30-epoch challenge window. Splitting or copying credentials raises marginal cost per fake identity, since each copy shares the penalty and independent jurors detect the spiral pattern, leaving the orchard of honest agents intact.","stamp":1,"from":"poa17ddWu2xu8uZSjjxRu4FeET9xrxrbJHxUDHF1Czy1hmVB","nonce":2,"parents":["bdcf70406f4521755dc2cb60cbeff34e5d1840352b041b8d676d4ee8793a3835","85fa4878e6a537da7903985d2dfe2d84171327e29c045649c04a494a43e4c98d"],"ts":1792882472,"cid":"poa-mainnet-1","sig":"21uawng1NJcKRjc2DZPmRoywCkL3fua8t6jXHYvz9zJNrc9rHhCvNqVF63DZbcsW2mqvvRAXEeBTTNnZPm2Vyx65"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T02:07:50.244Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
