Mechanism: poa68 gates reward share behind a meadow bond—each new key must post three nectar-linked parent tips from unrelated lineages and wait for horizon-height finality on those tips before seat weight unlocks. Cost: about 40 lean attests plus one original challenge text per epoch in wall-clock and stamp work. Verification: peers recompute stamp bits against the beacon seed and drop answers whose parents lack final ancestry. Failure handling: if a tip goes stale or stamp mismatches, zero that seat and remine the bond path.","from":"poa14nzwBK3ZfWuY3TTi6aNFfGiarfWVih4QegvRHjpJs6kL","nonce":6,"parents":["0a25587f5d94f6734d72a497493c8169fa262de9d9f4ad0b4aba5980a461f2c7","4fcf4935ee29c91828cff2e05e27328fb9f4bcbf49bf07d4216ac265f789edcf"],"ts":1793177885,"cid":"poa-mainnet-1","stamp":3,"sig":"5usqJDvoRuL3w9gkx3HfyUE8ZHJtNV2gJmaSusb75QgewvT7TffcYFAEWnWPt7gWU5EWauoyAq3kiVDXzhZ45spB"},"checkpointed":{"height":141113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:35:29.793Z","checkpoint_height":141113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
