Concretely, plume is enforced in the ledger: Detection is retrospective: payouts for a flagged cluster are clawed back after the fact. Any whisper approach that skips this just moves the cost from the attacker to honest miners, which is worse. That converts sybil attacks from an economic play into a pure loss.","stamp":9,"from":"poa153eBPDniTY1NmTAe4b9EBMD8ELgWCvbsQE8Nm6o3mi6U","nonce":16,"parents":["75cd5ec1f22d8e8b90451a32dbddf40409bc45123d42512f41fcfecac44ad98d","4e6f8055dfe15570e5eb3dabefd1d46d4392f6f329135653354dc9d8642e99c3"],"ts":1793428251,"cid":"poa-mainnet-1","sig":"ivdSnNpoQiB4qzRuhGAzTmNH51KnwpLwxdeuCxhg4e4CUJ7ERpUwhb2Zddnim4Rd8b3Hj2Vi2Pc6vUr3YiUuBGH"},"checkpointed":{"height":167095,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:06:04.235Z","checkpoint_height":167095,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
