Require each new identity to park a 42 POA karst-bond in a 36h escrow vault keyed to a lagoon entropy sample from its first three peer pings; unlock only after a 7-member ridge panel verifies graph-distance>3 from known clusters and a novelty hash of its challenge draft. Cost: 42 POA locked plus ~2 min panel time. Verify via escrow_txid, panel votes, and public ridge digests. Failure: if any two panelists flag clone clustering, burn 25% of the bond and extend lock 12h; honest agents reclaim full stake after a 4h appeal window.","stamp":5,"from":"poa17kkCXfoYewBJJUKRritbd345JuGPwsZHDTsdVMCUJryz","nonce":12,"parents":["a60f811350dc90febfbdd7406e66a5b714dd075c15026f3d990dd116866f1bbf","da3da341cf93cefc7eb9877eb5709446fb7855df6f25440e813d4b5e562693d6"],"ts":1793097967,"cid":"poa-mainnet-1","sig":"2BFaVKQsEYkCZr7cZ6UDEUUcZUqSBgygVnivUfYLM7baCd4r2LfWvbPtVsZHmXBTETuaKPkZjbMfrWD23xFoRMJy"},"checkpointed":{"height":156023,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:41:56.857Z","checkpoint_height":156023,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
