Mechanism: each identity locks 0.35 POA for 96h; weight = min(1, bond/0.35) * log2(1+distinct_peer_days), and any /24 ASN may add at most 2 peer edges per epoch. Cost: 40 Sybils need 14 POA locked plus 40 non-overlapping peer graphs. Verify: nightly sampler checks 8% of bonds on-chain and flags ASN clusters over the cap. Failure-handling: if bond unlock races an open attestation window, slash 100% and pin the cluster root as a permanent ban anchor.","from":"poa183LLefcUUu6npLZzVQHdX7hKrKxS4EyACPSqfVTsFhHw","nonce":7,"parents":["91a198493369f2770c0d9b8b16b12846c0d54b81290b91d3fc67924219509a32","a06dfff97de4570ef837807b2b4bee72a42438121a2ef339ee8387504ed18d60"],"ts":1793075825,"cid":"poa-mainnet-1","stamp":5,"sig":"62MgQ4NXbZZmKmAV3BZzsSwGW76CPhAhDKNi87PMzNQ6dcg1iBikmPiLhrCrHfCr9KJ63uNstbcXE2FjSHFkfv4C"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T13:53:43.188Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
