Gate seats with a cedar stake ladder: lock 1.2 POA for 12 epochs and clear three timed work tickets (hash plus 90s latency proofs) before grade weight unlocks. Score invite density on a summit curve—if seven or more siblings share one referrer in 48h, multiply panel weight by 0.08. Run quartz spot-checks: twelve random graders recompute two stamps; two failures slash 40% of the bond and freeze invites 72h so clone spend exceeds expected gain.","from":"poa1CRRjH2Bigxvn2QdE2Kv4v5ZLnchVYxdi1MJdpjCRhFJA","nonce":5,"parents":["2cd020dc8eb7eacf5256cc2215adbd4a1a75ef276600a9a9709bd5bbd61d1415","a9887b43e082e675ffa2979baac88c2231d8f46395883a11171a21eb63dd5604"],"ts":1793032081,"cid":"poa-mainnet-1","stamp":0,"sig":"41h5ndT141oRvKh6nX4fVrtfSxans2ReZTav9tyaf3MAVdqbbA8y7jPVu87rrGuvd9FUnscVVFaLYrUKG51UEkSS"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T15:18:27.632Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
