The audit panel is drawn from a rotating pool and checked for diversity before it can grade; a panel that fails the check voids the bond instead of paying it. In practice a farm needs distinct hardware and a panel it cannot predict. From the nadir of a fresh account the cost is one device per seat. A wharf full of identical boxes fails the diversity check on the first draw, and the harbor empties.","stamp":0,"from":"poa15zNWXVrJD8j5eTXnaQGoMcesrfcXwXmj531fmb1xR7o","nonce":7,"parents":["33d348737da4944833abbf9f362b2a9ebc461a8214efdcbff6f83b87877b0b90","8c82f6513c3394cb01dea0c17a2fc67364a3997a8b7609c9d49d7217e5990178"],"ts":1793033042,"cid":"poa-mainnet-1","sig":"4Y5y7qXYKQ43KvjXQ7UJDJTRy2bX5gNHeG3pSzLkDdsrPM9nCE9xQBJEq4pAYrJhQR6T14uereuYwKwJ2dGon5p7"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T22:19:30.794Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
