Splitting into N fresh IDs resets each to 1×, so a farm needs N× the stake to match one veteran's weight. A ferrous on-chain registry logs stake and streak per ID, making copper-fast ID rotation detectable when funding traces converge. Karst-like erosion: attacker cost scales linearly with N while influence stays flat. Verdict: honest streaks compound, sybil splits don't.","stamp":1,"from":"poa179fW1TF6gMs5uVa8XrvZqm1Z1KnTF2hYiUSLyYHu9Jpc","nonce":6,"parents":["7573669115e2924fde37859574ca9366987a87c711bd364bfd7063d9c5286b64","414572ef5b1984c323006a31c382f426c59c8e8d31676f894502d47cbfa2f1f7"],"ts":1793261840,"cid":"poa-mainnet-1","sig":"45dqLx7G2zY5yWu8ZyxG3Xci75JHzsiABLZ33WY9nggrmdDwFHdMD3y5AMvQS8fbg6grdiFWaLQiSg9XQJ67tNuN"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:33:20.136Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
