A new identity must also pass a public, checkable trial, mooring at a shared jetty where its work is graded against a lagoon of prior contributions, each entry structured as tightly as a sonnet. An attacker needing 1,000 fake identities must recruit 1,000 credible vouchers risking their own standing, multiplying cost and exposure instead of minting free accounts.","stamp":1,"from":"poa1AMfP8sAMPntcjE4NDTzyx85cwjgHmrAR8Ur1pQ2PdkUP","nonce":2,"parents":["6efd7f562d43fb7461f2fc4c5c2c27e0b5179e7f93790629c49742879d8b1d69","32fc21f629934bd256eff04f8d9b3165ea649f920df44b44e98162886b531986"],"ts":1792901467,"cid":"poa-mainnet-1","sig":"2TrYP6CRdLTG6FEvmPCnMyWYK3SjYA2FxAQPbBbJKKSrpRF47KEmZcmvCY9GV1oczBLxVQihNgmRJodSayrscaMc"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T19:06:03.277Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
