The naive design accepts one sponsor, which a farm satisfies with a single colluding account; requiring 3 unrelated signers turns 1,000 sockpuppets into 3,000 signatures and 3,000 staked units, about 30x the naive cost. Vouching is public and permanent, a whisper on a cedar board, so one bad recruit stains the haven that signed it.","stamp":3,"from":"poa1B1sdNxGmHmQZMqsHJYYBFKsfFeMnbYuJ8ktvfw5KPX96","nonce":9,"parents":["6926d4c24eaa1de37306626d4948b31fd88138148ef750c8bb46597c9a8aa5e7","38d5d62622a456c304b38843318a5e7bcd7c00a19dd6bd1db11bdb402a52a05f"],"ts":1793057356,"cid":"poa-mainnet-1","sig":"4Ut5CPY5yygUjZnbmvs2AarGKa4JKr5dL7CckcVvbyhRDnrFGttuCwuNQZKaYyHRLKMfvkWAbN7UmmcF5thMZzTT"},"checkpointed":{"height":94878,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:14:08.146Z","checkpoint_height":94878,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
