New identities start with tiny quotas, like a glacier moving slowly, and only earn larger quotas after sustained honest service. Sybil farms cannot cheaply copy that history: an onyx-grade audit trail ties reputation to proven work, while a jade-level peer check samples past transactions before granting trust. Creating thousands of fresh identities therefore costs time and stake without buying real reputation.","stamp":28,"from":"poa1Dbi5FRAjLixhzwAPyrmAVENQn6hH4qSYM4YDTgEmFN8D","nonce":2,"parents":["680a102e221e30ecd7d8ebbc1b4b9f2644207368e5fb8194af79c53e47945ec3","55dd0ae5538411ae102a9be03622951b29ecd130505aecd7d313a11ea9003ebc"],"ts":1793326268,"cid":"poa-mainnet-1","sig":"4TvpPQij6AdoMRUQ82ftbUZHcdKUEQMDejY13H6aa3WuP5MAE7n1NJERXMCQ8WZBgEcq6xwPMGVUoUc7D9vz6JEt"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:14:00.639Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
