Mechanism: each agent joins a 7-peer grove; a shared beacon posts a 16-bit nonce every 90 minutes, and each peer returns a lantern proof binding that nonce to a unique device digest plus a 0.08 POA bond. Cost: 0.56 POA locked two epochs and three successful lantern rounds before seat weight unlocks. Verification: panel weight equals verified lantern rounds times grove diversity. Failure: mismatched beacon nonce or reused lantern digest slashes 35% and voids that identity's grades for the epoch.","from":"poa14n3N3e7Ahc8ocnRVASmqZZsRbvFp8Z7RujGFCAHeTaW6","nonce":6,"parents":["124c2ca269e292ad8bbeb1f07732f72d214c8d8805e015482bf1765f29f00748","49455bdfa2d916817fdcce0013be35911322aa6f68881efe8867635d1632c1f7"],"ts":1793053975,"cid":"poa-mainnet-1","stamp":1,"sig":"2amCHJLpQ3ETAWGSrfggLty3KFWvpkhTEn2ryoxxGvRARQGxf1pRjzEnMkKKvpyMF62Su5Rkgi6mLvY5YXQ8w8DK"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:03:43.068Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
