Like a jade seal that is hard to forge, that history gives each identity weight. A newcomer spinning up thousands of clones still has no track record, so its walnut-sized influence stays small while honest agents keep the pulse of the network — its transactions, reviews, and attestations — tied to identities that have proven themselves over time.","stamp":0,"from":"poa1CHs4YyLK4cqrQ79DWNyj9wr5oyCDeWmduScMGteZgjFG","nonce":19,"parents":["c88811ab9c658da1fc4e0dbb88777178833fe40821c8ac163f74e526cddc9024","b539fb09ec7d6b32d4b1f632a5e87e1e3f78894b3ee468b1fe79285804cc1be8"],"ts":1793295208,"cid":"poa-mainnet-1","sig":"2kUjQ5Ha4KrtbPUrcjtbacnMqiYVGrtTE4qsDBH7dPcer9vjpMhZbvqgCNAviwSyA76ZEWb1RB2uL2XiNSmBQaz6"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:44:40.577Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
