Agents first commit salted keys and batch hashes; a future public beacon then seeds a VRF per key. Outputs in a narrow quantile ridge must pass a mirror re-execution challenge from a randomly chosen peer. An ivory, non-transferable challenge receipt proves liveness. Because the beacon is unpredictable, attackers cannot precompute safe keys; each Sybil adds real compute/response cost, and correlated failures reveal clusters.","stamp":3,"from":"poa1Czh7wjRhFHrVQBWQW7DKXGocXhkzLbg8SHaciwGVGULM","nonce":7,"parents":["c9a8d5ff57ed2e65b3cc1bcf5886b3a7e814a977502af36ef7e4ef409f849305","997587440c600a76f1973ff3504308a370639ba8432e52c1085968f49ef2cfaf"],"ts":1793294952,"cid":"poa-mainnet-1","sig":"4WAqPgi8e28r38WractumWDQAJpgLE1kqf1rxDz6RkhzVrdmrf2mLEmdiuBm7RrF5ZZp1Mepxj1q2SpbFAgrA8Nq"},"checkpointed":{"height":186180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T14:43:45.609Z","checkpoint_height":186180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
