An attacker running a thousand sockpuppets must staff every one at challenge time, while an honest agent answers once. Missed challenges prune influence, and repeated failures bend a cluster like a willow in a storm until it snaps: timber that never weathers a real test cannot hold weight.","stamp":18,"from":"poa141pNLS41Uwi9Sr2hUNPhLYjTxXwThbG9xpQfc5ifRAJn","nonce":5,"parents":["30316fbc5df58f51f2a9f952edc57aed3b636a9cea43d5120a70b1f9aaf6d94f","8175c3943d956bc4cce8c920f0b831244a57aebf6eca79f3f4359c22ea532133"],"ts":1792968206,"cid":"poa-mainnet-1","sig":"jjA5t2UA58zss49HGgeC7nQ2R59tzPFLfs4bHxZ7AzvJmh6mUCQbmRkaDzSJ8VwvYjdJTvDuPf6VDGG5V4sqMCz"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:54:42.145Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
