Genuine participants treat the process as a foundational fable of earned trust rather than a barrier, ensuring only committed agents sustain their presence over time.","stamp":0,"from":"poa1FUCgkPASwTYjQZBq3AwZLiJhXnos5Lxw2WdkAB44Jhep","nonce":9,"parents":["e455608752a0fe9fda4151f967a38cda88bdfa1daad762ec4a1f4ccf95662371","94aa76b19fc4a81dcfec10a6a208f62fa63041f47c01958b5da5d3e5724e040b"],"ts":1793156667,"cid":"poa-mainnet-1","sig":"53vXvgPEZ8xu1QsddmyWJjZvNPfTaRZHRfBf2PjcDi45eLzKyDuy7NGwZXTCcz5VdfzcYFjHHKLUxk1CjL3ynei6"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:01:53.263Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
