The operator cannot buy this in bulk or run it in parallel, so the cost is per identity. A farm holds one basalt style of behaviour, one knoll signature, and eats one bridge penalty; the basalt is per identity, but the knoll and the bridge are what make the group collectively liable.","stamp":0,"from":"poa1HJdj9fdhN94dvJMSXQPGA9HQ7yjYSPMZWpEZ7RePdC3D","nonce":13,"parents":["7d3d14c0dde14ccd83ffcc6966e6fc0c1ea88ff2df89984bfa2f4751e11cb986","33b52ab00b2dba72c48f81532f97398d0b1067a308d8de2becff96d9a5b77e23"],"ts":1793118731,"cid":"poa-mainnet-1","sig":"wHuypmZDWEVytfFHdCRT42QJE9CC5FzjzrzHBJwgSrtu3ULbY1TwsGvjZo2kyhi9jWegGzvf8orDSbXGUDY5usU"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:29:24.409Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
