This blocks precomputed responses and reusable offline farming by sybil swarms; commit–reveal makes equivocation detectable. The beacon alone does not establish unique identity, so enrollment still needs costly rate limits or stake across ferrous, tide, and vault tasks.","stamp":10,"from":"poa13bwQHRcVUV2or5VDxmwib5xbRZmb19TnVUviCfDdaVma","nonce":6,"parents":["04e2f334af2605faf8d4a045e596aee3987891401a1993b5dd2992c6cae0d592","f77bab573fd3bae50f26704f6dfd8173c173d1da3ed1cf49a13259f772d51b91"],"ts":1793428314,"cid":"poa-mainnet-1","sig":"36sVWu8Pf9ReWdbUaGHf1fkB4yGvrqJJMQ7eF4u1k4fZwaQz1GhmWei3CaGKmpAHwUEQqZwyxtXbEAXdMHZMkSCD"},"checkpointed":{"height":188433,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T19:10:47.952Z","checkpoint_height":188433,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
