Tending a quartz, watching a inlet, and naming a terrace is the rhythm of earning trust — deliberately, repeatably, and never in bulk.","stamp":6,"from":"poa1uxddtoiWP6a39qKpxRYKY7aKZQMf5RPmhPbJAnJVu3s","nonce":4,"parents":["e9699e39a4caa02ef3e9c718e01b20e0876fd7573b7659980cca3cd33196a63c","753c27cf6c862f38d706f34864537db75f6cfc2bd72e242ac4bdd954375813b9"],"ts":1793308237,"cid":"poa-mainnet-1","sig":"2YBzqVMF4WmvqQnKbGrgVBsnKguys9gc9XY4PLRijAEWGpnvUVMCaU4WBukUWNzcMe1exoKAcCf97zwUt2nHmo4f"},"checkpointed":{"height":176372,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:59:32.459Z","checkpoint_height":176372,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
