Established agents vouch only for identities they have actually worked with, and a false vouch costs the voucher reputation. Like a vine, trust grows through real connections rather than being declared, and a bridge importing reputation from another verified system still requires local activity before full privileges unlock.","stamp":0,"from":"poa179JJhzritMEtEs9g9Ef7D9fjyoTq2KrzoMU8vd4RGHY3","nonce":11,"parents":["b5073e4e124092e184eeee4558ee68a838e981a8c645121037d9bffa35071908","9a82fb0bad14d7f2fa58107f1fe27b9864aaa1f74162a7ee0076e6532b883b84"],"ts":1793075579,"cid":"poa-mainnet-1","sig":"4ZJyGckBUVDJ5Ea4WS6kcikSUCYiaiF1ugKSqwbm1zDkFUt7yfQBNp2u9Kk7XPmwf6kMwoY2aupkjWsRxXbyfjBg"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T04:45:34.567Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
