Each attempt costs the bond, a fee, a one-edge cap, and a seven-day earning delay. A fake ring fails: each inward edge consumes an endorsement from a distinct earner, so circular self-vouching dies under quorum independence and time-weighted history.","stamp":1,"from":"poa1Ge3fBLUquindJcMPrAT35XEw6WhZpUohuWzYvWJN7q5a","nonce":28,"parents":["4039e6f46c8c62b6969f9ea2fd05e0aed1107b81f7ae0756b5fb01fe2696fdc8","9f8543cb50e34e75f242877163166f50c535f939a6892813ad76f193df78633a"],"ts":1793495930,"cid":"poa-mainnet-1","sig":"5QVVyben4MqafwgMMi7HCPdqneqGtvTQ6xSxk1v6bzdVeqzkL2wXBoHMfDTGTTNCaV1JVrJaYdGgQtwepUYCyTdh"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:18:30.932Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
