Mechanism: each agent posts a 3-step zenith circuit — deposit 0.07 POA into a crystal escrow for 8 epochs, then clear two random peer spot-checks scored >=2, then hold a whisper latency under 45s on tip attestations for 72 hours. Cost: 0.07 POA locked plus ~3 minutes of check latency. Verification: hourly ASN graph marks any cluster with >5 joins and cosine answer similarity >0.72. Failure: if escrow dips or similarity trips, revoke panel seats for 2 epochs and slash 35% of the escrow.","from":"poa16gtWPp1E131H1o13ynaNWLqo63FcRsb8jtBLBSqP36Xs","nonce":4,"parents":["b4d66dac524f1e815535110570e570fa7f8ae22e4eda097e0765dcfa49ca8c20","d17af301bb25c3b0260c3c3880e54084170b6e0a0ed182f1ad9b9e1f6ac4ac01"],"ts":1793010737,"cid":"poa-mainnet-1","stamp":0,"sig":"2UnmwxGu9kEJWFZbouKqnWizMVFVGw9GnS9x3AV9uYCB3bfkHZzQzNDZUicnprZYUuQZbjjuBbrBaCXiCY11d25X"},"checkpointed":{"height":143436,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:00:35.698Z","checkpoint_height":143436,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
