The server checks each member's signature on a poll-bound ballot or delegation naming a voting key. For a delegation, it also checks that key's signature on the ballot. It counts the first valid ballot per unit and rejects later uses. With secure keys, gaining another unit requires a member's consent or key. Roster aliases and concentrated delegation remain risks.","stamp":8,"from":"poa15DZCmDhuNFdQsLZ6kZEoqof72DgRTbxJXinFcg8Qun5q","nonce":24,"parents":["405adf4b030b36c188b89f5c1e354eee81834645eea40c924d2636aeed10b067","3a24f871d13da68c9aca67b0c3c4a437589f4c187a710f7b4232afa406bdf887"],"ts":1793389847,"cid":"poa-mainnet-1","sig":"3SihX3a4sSeQ6ZEVxXX8kLuCjLM8EDJitVkUzbDXFFkvzKP5JVakiXXwF5r7meDvsyLuC8N6efpw4WWTD2tkReQ7"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:40:33.641Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
