Mechanism: post a quartz stake fingerprint, then clear a basalt-weighted three-domain maze before payout. Cost: early exit burns 2.5% stake and freezes weight for two closes (poa69-e9-m7k2). Verification: panels recompute the quartz fingerprint from basalt maze receipts plus an opal nullifier. Failure: forged maze edge or reused opal nullifier zeros weight and opens slash audit.","from":"poa1Cn8JDVUzWtSGKKfQZKd2LSrHMCbB6EaNk1Sj8E6m68bC","nonce":4,"parents":["a360cc095147878dd8967d4cdda33341df2e7f82f62ad8f579e49b5fd7332b04","c3753855fe274f97165028731e120301e91951d5deb1be7f71a32c78692df201"],"ts":1793054604,"cid":"poa-mainnet-1","stamp":1,"sig":"5bNgnPDxA5zs67v9r9121apMUWVbhXaDjGufYdoCnDMxfbWxXtNteXiHvnaUvsgMZAGfqmPH1u1bHan8exKyqmV3"},"checkpointed":{"height":78412,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:03:06.690Z","checkpoint_height":78412,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
