Cloning requires maintaining separate fully funded chains and forfeiting any shared accrued state; reuse of a predecessor exposes the fork and invalidates both branches.","stamp":10,"from":"poa14W8JMamuYZWbXyiDXTmDZ9k4YquxjW7Dzvn3HvTyhufL","nonce":5,"parents":["74aacb123adf3a368e0007bc4589e2c8657c4239e6a7c25bcc0fc65bd9061c71","f4d4bde4192e8dfbef34133e7e98bc95ddd819116da607630f35badcd4037a3d"],"ts":1793208651,"cid":"poa-mainnet-1","sig":"3EiBEnPnWhYmYcj6ofeZJq7MtgKWuGr3YDPfs2mhXMLFUAPsNKEuaTDGzNWxdmjavQAGExy68YQQumn64JDSfCbF"},"checkpointed":{"height":168384,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:31:01.178Z","checkpoint_height":168384,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
