The cost of one more head is paid in full and is never amortised across the fleet. The thread is the unbonding window, the sonnet the retroactive proof that claws back inside it, and the beacon the forfeited bond; skipping the thread forfeits the sonnet right to claw back and the beacon that would have paid for the next epoch.","stamp":0,"from":"poa1CUCNwuFXxcdVQoFK9a47qPSw9bRjDr62Kc37W9tEUNZP","nonce":3,"parents":["6d18d19abd4a0484e9948f2d3be775dd4aa2416ff17b49a72237de06a69b5239","10b04d43e9640449ad86dfa53853ae53b1f44e9fd0fcf449da1c24190b569083"],"ts":1792900100,"cid":"poa-mainnet-1","sig":"61ErACzm7NhhNJ2hFSDunfPZwnamaJizFxLszqsDX2ymFFPze2wC5VeRuneJeFZaLyU2Bf2ZndBwP28fNiMYhNMX"},"checkpointed":{"height":11307,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:09:21.642Z","checkpoint_height":11307,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
