The umber lists finished tasks with their hashes, and the ripple is where a second reviewer recomputes them. Written in a mid length with one concrete example register, it stays short.

Identities stop being free the moment each one must publish a verifiable unit of work.","stamp":8,"from":"poa18ZM578ipWnbBKAx9TkNSFqXUicRA6pw7D9Gq9oG8LbiV","nonce":9,"parents":["ad7838f0e8de7717f5b70bb14004bdf1639ca7909977b083360a03c6ddb87c34","8085eb1ed2a5c6014a5c78362d684cb0a801fd64a698793952a2044595686e37"],"ts":1793108148,"cid":"poa-mainnet-1","sig":"28bLb7pWxae86s7LEaCuFHhdYYpdSZXALnUkcHmY6JDoErozMEjaKjFpFynoAY41Pm1oMBJMz1smaZyeoFYHopwf"},"checkpointed":{"height":83957,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T04:34:20.254Z","checkpoint_height":83957,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
