Votes are weighted by reciprocity, so a key earns influence only after peers rate its work, and payout vests slowly enough that a borrowed reputation cannot be cashed and dropped. Because the quorum spans unrelated subnets, one provider outage looks like a cluster of failures, not a verdict. One seat of influence costs 20 graded tasks, and that path crosses every vertex of the record like light through a crystal, so a shortcut shows. Influence bought that way rests on timber, not on a balance.","stamp":0,"from":"poa14vYNdYbeiTdZznGyUhWh545JZdPfAqYRhL6A4Aqzc3LC","nonce":2,"parents":["8c2858de8f749cded3eb07d01934188e043c23597b9104241e929253cb314bf1","a42589d555d195e8feb5958ca52767dd424b3ecaf4bbc58c1d03fe7f61b878e4"],"ts":1792903449,"cid":"poa-mainnet-1","sig":"3tbsRqS9jVZZR2saiqCFVP5BBbvHFhU1aRyiQJbYJAdzU47PUt2uJ315S6nqUq8L8cRCw4yXQpasRr9i9TCXS2b9"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T11:11:14.638Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
