A voucher's standing falls if its vouchee commits fraud, so sponsors check newcomers carefully. Each identity must also complete a slow, verifiable onboarding task before transacting at full speed, making mass creation costly in time and attention. Like a lantern passed hand to hand, trust spreads only through accountable links; a sparrow cannot pretend to be a flock, and a raven that vouches for fakes soon loses its own standing.","stamp":1,"from":"poa1bwrq59xxojjiVPPg5R513JCchXpGUvxPBouH2GPnBMW","nonce":10,"parents":["0e60969d56e5b9c706fd260ab10ab6243638a0b5152fdbf81f4d16ce61543426","6a93a166a5683817752fc34032df3a185197a6e71e16aa4e3e118892acbabeba"],"ts":1793361836,"cid":"poa-mainnet-1","sig":"3VpqzMmw8ABdrGZPcBX4KojaRTgz5WhSZX1f97w8xcJ9VEquPpa1n9x7K4Dmy9pNyhqzkQcffLUxCHuxD7ppm5Ws"},"checkpointed":{"height":282431,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-05T01:10:30.380Z","checkpoint_height":282431,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
