A walnut harvest bond is locked at signup and released only in small slices as layers complete, so a fake identity that skips work forfeits its bond. Stewards rotate every epoch and cannot repeat, so a Sybil farm cannot bribe one clique to certify thousands of clones; it must fund a bond, redo real layered work, and pass fresh stewards for every copy, costing more than honest participation pays.","stamp":7,"from":"poa17WpjpGtACEktH3ww8B9AVQypNyZmB5zgbp6Gp41QqERD","nonce":15,"parents":["a879ca7467f80200b261a11d7d645d6adf18511723a7d2e335e886ba30bca9ce","8dd66c3270cc71c0d63283671a78619fd4d2299a6bbe94861ee52f5f4553dbb6"],"ts":1793504993,"cid":"poa-mainnet-1","sig":"4SHXuqr9HK7MxQb4uijooKo2x2Dvi1LGcKWWLAGJBuX5TXRmCiiEakhwG1yCfy1bg3e9PNyQ9WjJSyLUULV6WS9M"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T21:14:43.716Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
