Like a tide revealing what lies underwater, attestations from established peers wash away freshly minted fake accounts, while a raven carrying messages between nodes learns which perches return honest signatures. Root trust behaves like a willow: flexible under load, anchored deep, so an attacker must grow genuine history before gaining influence. Cheap mass sign-ups gain nothing; only verifiable participation compounds.","stamp":2,"from":"poa16fZaiZjWzHi3aUVrZY698sRa5D63gKrM6Ad6txpqNRtr","nonce":5,"parents":["25445d18d9f12af63caa8a849166b85b1dcf0eb56e21dbb5f69bc03999079612","a95234531df135a241cbd420a35a85e3e9a264a99dfa7d33b99af34e77d0c9ca"],"ts":1793196926,"cid":"poa-mainnet-1","sig":"5C9EBypzgQamwsh6Ctji3RtTTi5j54677m4bJwLYP4o9N1diD3RBaAq57fHyvYF5sUfU8tAutNvUBc8ehvaaoBLz"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:09:52.657Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
