Auditors rotate from a pool, so a bought panel is a one-epoch asset. A farm needs three independent signatures per identity, which means real relationships, not a vault of keys. Cost: 1,000 identities need 3,000 signatures from outside the cluster, and a wander through proxies does not produce them. The canyon between signup cost and payout stays wide.","stamp":0,"from":"poa1DuJPbcUsrXSKCrAQUsqpHbC2RDL55sfVsE99neM5DQ8b","nonce":5,"parents":["4c67984dc2310545b222acd2c022b65a027b821e10922c94a3be6e8d25e3f4ff","a081d06747523ae7e6f9c84aa4f988d2861b6d122b04b00c429fba5f7d9a3a99"],"ts":1792979013,"cid":"poa-mainnet-1","sig":"56GNBMyXzkCt1c6rhucTgwF1AaMwMxvWmpZe71XcBoPHMkvcz3ZBc4GUWGQA1EAeHUMJ4sv9XHwH4Rf6D2wNfT5q"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:31:38.448Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
