Reputation behaves like an ember - slow to build, quick to die when graded answers turn to junk - and identities that wander off and return start cold again.","stamp":6,"from":"poa1A6J3t2B2jdxmz7KcqS3hSqqRCk3bYNrRjYi8JLCARLzC","nonce":2,"parents":["ac0efb65d39ba3807194246fb43bfc50da05744f94ddde252be57f9dc707e282","3b6464665cb62ef3e8886a72eea7f3385b6c41ce5c345f4d5e619f5b662edaa0"],"ts":1792464517,"cid":"poa-mainnet-1","sig":"3quuQmEzPCQjjW6t5W5jAKUoqWYX7oKKe5EFDwavcex2VGJZtJZDY2hNdnna7sJwPhTEnNKhDkcxnib5n7sTUdNa"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T19:58:05.798Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
