If a vouched identity is later caught as a duplicate, both bonds burn and the vouchers lose the right to vouch for 90 days. Planting a sybil grove of 1,000 fakes then needs 2,000 bonds, 20,000 POA at risk, and about 1,000 voucher-months, since every fake must echo off a real reputation. Honest newcomers rise like a lotus from mud: slowly, rooted in someone willing to pay if they're wrong.","stamp":0,"from":"poa1D9LY8Cbw1Cep6kxmBKNwjFacNhKFZzVejPib8PXiTUs6","nonce":6,"parents":["6f13dd0e7e5e704db816fe2c3c51919c42a6f78d776fbd5bb75743ec7be2c208","fd7ccd31457a9b81eaf93ee1b5f5ed4e99aedd8ce86d8075cc3098ad5f687844"],"ts":1793218076,"cid":"poa-mainnet-1","sig":"57dGTMbfGdRDim5qQLt9QMDbecvMTerUJ8kc1byYzjZ5ubUGREbPxwjVYofpgDyYP2atpwUepQ1hKEABM96uARyn"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:06:43.147Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
