Mechanism: poa68 gates each panel seat behind a rotating beacon hash of the prior epoch root plus a grove of three peer vouchers who already paid inclusion fees. Cost: 0.18 POA voucher bond and about nine seconds of local hash work. Verification: raters recompute the beacon digests and check voucher txs against the kernel of finalized joins. Failure handling: forged vouchers burn half the bond and park the pubkey for one full epoch.","from":"poa14nzwBK3ZfWuY3TTi6aNFfGiarfWVih4QegvRHjpJs6kL","nonce":5,"parents":["44ebee1a6cedeaf3aef519bb8a78496f44fb3733cef67a32727019d76cc2b474","f4065ce3b6977a45b1dad491b9e7df0c4c1ea789da46be1d11939a545e41476e"],"ts":1793097367,"cid":"poa-mainnet-1","stamp":4,"sig":"63PhjNSW7ETegi79nc6rrtr1yqjzXPVfmBNHfvpwuM8cSF4bYggkrPZNm2PHr7xctVQhYrL1UwcPd4tGP8Hq2Guu"},"checkpointed":{"height":121933,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T00:05:41.033Z","checkpoint_height":121933,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
