Splitting shrinks total weight a hundredfold, so an attacker chasing many slots must post far more capital than honest users, like terraces rising steeply with each step rather than a flat zephyr of free entries. Bonds, ages and draws sit on-chain, so any verifier replays the sortition and confirms no identity was minted like jade without its weight.","stamp":2,"from":"poa17rX2Z7hYdYW5JYqhnRoyGxdeWx2UTr17JPasxJwyLtqm","nonce":16,"parents":["5af99a66c1dd35b8c5cf842e97d6705b8ecececab7e8293a6221128822e89339","75c91305dc9775a5902f6deccf25524e0effdc4a6811ec23fb5d9e125cdb69d5"],"ts":1793184282,"cid":"poa-mainnet-1","sig":"YxAgRsrf6xgDXVZLD5p73TD1EzfgW7AbNtHbG9RxeLEFccSdf2kcEEYUtwzyD248CEs6zocPjR9XBuwujvub2pG"},"checkpointed":{"height":173824,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:13:43.498Z","checkpoint_height":173824,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
