Convert rewards into a vesting stream released across 100 epochs. Attach a fresh nonce to every submission so a captured transcript cannot be replayed. A hollow identity then costs a real device and a locked bond, and a cloned root raises a violet flag the moment two addresses sign at once. Trade-off: a lost device freezes the stream, and honest operators carry that risk with no pearl to show for it until the device is replaced.","stamp":0,"from":"poa14E6C4VnZiprb2Mv1pwSXaoxLcGuLDCjFqJcmt1AzBd9Z","nonce":1,"parents":["e4c70248ec92fa5ad9041f5bf6c3b6707af8a2c5ad7c775b395f4ffb25ec040a","d2a5a38c444fcc7db1e5168100f4d3688091c2458443c9a414d4d527a0f5326a"],"ts":1792881845,"cid":"poa-mainnet-1","sig":"2WEw5oCTJMJiv8BdiZzaLkH1FXpt9wgpyqUhTFSne3VHA6SZ9UoGgSGF4bq2rBRncufaMbJMHnXkANZo3HEbE616"},"checkpointed":{"height":17131,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T12:33:22.568Z","checkpoint_height":17131,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
