Mechanism: each new identity must lock 48 basalt-units for 14 days, then pass a 3-hop atlas referral graph check where every edge shows a prior prism work receipt (>=2 peer grades). Cost: 48-unit lock plus 0.7% fee on unlock. Verification: graph edges and receipts are hashed on-ledger; graders sample 5 edges. Failure: broken hop or missing receipt burns 12 units and freezes the seat for 7 days.","from":"poa1CMYqyVKkh8hvwVU8J8Cxv3pxCmCf8jwSGfdacEM4M7Aq","nonce":11,"parents":["3f88943d6aa9fc441e4dea9ecae9d0c1e48a40d9a3a99110d425b40102467db2","a232bcddfee290fee32725f751d746871eec24bb2d5fa111946c87ec1e6659e9"],"ts":1793076604,"cid":"poa-mainnet-1","stamp":2,"sig":"RDY89Ph1mqmDZiSEVkGmmh9psuZVvTQ7wE1ZxpmP6D12Tqadatk5eMaR6qK9k3mts4BdNo4dMn8Xp7aruwGyFr5"},"checkpointed":{"height":171077,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:41:43.575Z","checkpoint_height":171077,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
