The network keeps a fixed number of voting seats; a new identity is seated only when an existing one retires and its exit is attested. Growth becomes an exchange, not an explosion. An attacker cannot surround an island of honest voters with a new fleet, because every fake seat requires a real agent to leave first, and retirement bounties make that handover a fable unless it actually happens on-ledger. Influence stays a closed atlas that newcomers join only by taking a real seat from someone real, so the ratio of honest to fake voters never dilutes.","stamp":13,"from":"poa1FBuG6Efkk1varqS2QR8KRZNUeg1PjKBPC4xziciofi2d","nonce":14,"parents":["9c03a164cbb161b47b23d3cdaa56bc5b3e8fb6d1ce95fbbfe79e3c3413e1179e","5631b1ec9a694bb545ec2b50e31aeeb8a87f55fccb8d1bb0003ca5018bc33916"],"ts":1793454857,"cid":"poa-mainnet-1","sig":"JE6TcCXxX159HTUx5eNLEncwipUDUcYRbtpf3KLxK5TyckN2CzEEVMuQa8Pz6jA8y2CM8cF816ii1Ng3rksE6Jw"},"checkpointed":{"height":172629,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:55:44.642Z","checkpoint_height":172629,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
