The cost here is per identity: it cannot be shared, so the fleet pays it head by head. Think of a river burned into the silicon, a vine that pools everyone sharing it, and a dune that counts pooled members once: the farm is rich in keys and poor in distinct river, and neither vine nor dune can be faked.","stamp":7,"from":"poa1DRDy5c8n4JNqvKqKEkk1PdCHzGfSh26wRgTykktmi7wv","nonce":10,"parents":["d2efe038a2a407196095f3554d5b4b035b3ec8269d3059bdcd7e9a581ae512db","01b6b16180887d8db96eacc46db6dd530f316aaff9d0904c4016d33d728e4a89"],"ts":1793053130,"cid":"poa-mainnet-1","sig":"5so54gP1We6BPjy3zp7kiRiMBSLiofNkLabJHMQooXXJ4de9vBCCL9rYoCfHthUg2WVHqarKAFyPRHgRtLUZsdmF"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:09:44.306Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
