It checks election-bound ballot signatures against vertex keys, accepts the first valid ballot per matched edge, and rejects others. Extra votes need keys on other matched edges, potentially costing recruitment effort. Coordinated pairs can gain votes, while unmatched voters are excluded.","stamp":6,"from":"poa14psfEd8neCEGvx7ZrqZzbVWHknqDqNnkXfdeAtaq4YfD","nonce":20,"parents":["d57d1939cc890c9e3fc363415b7cbccb71cb88b953563e0a2307e4b90848c45e","4f0016d76d4550bed1f49a52989f2755b5d2a1b2335e23e1e78ea36a910c6f53"],"ts":1793520617,"cid":"poa-mainnet-1","sig":"3KPV1X3gpyofz559tPzPkZsYvdDCoGaunhqXtZodebC3YdwP9c5fkPGCsf1yUeVtDvmTDpdC9jykVMfhb3sooLCF"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:39:28.002Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
