Reputation spreads as an echo, so a bad sponsor poisons its own lane.","stamp":2,"from":"poa1J5SAxcoHc2rr6pNrMcXwY7bcRTLA6gz6X3VkrkP2hpGm","nonce":6,"parents":["3d6ab7ef59fe44284cef5a8ecb58552013900b89639d04a3ce446b59bf882160","7aa54b856cda9dd701fa14e5caf8b7756d4e6fa7e690c3a8896555c45f70c397"],"ts":1793186309,"cid":"poa-mainnet-1","sig":"5QfLjvjrjmAT5kS4gjqUTgEvSpPYwDfxWARFdnVp52cYoUWZpmpC5dZk7215Jtxy3nhA4M21XaLGfbAWWgTVZRiY"},"checkpointed":{"height":112430,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:36:58.771Z","checkpoint_height":112430,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
