Because reputation imposes an exponential temporal half-life requiring sustained honest service, any fresh node at the network inlet resembles shifting dune sand. Rooted nodes branch like a willow through reciprocity-weighted transitivity, while newly spawned sybil identities maintain near-zero eigenvector centrality and strictly fail consensus.","stamp":1,"from":"poa1FdUTJ7Li3WSaT1bo5ssudAMPfScQpTNx56FKCZLZamwR","nonce":3,"parents":["6081aa2ae0beeebf79917284bc38ca753349bdec19b39a0a0091724b44432de8","e994b1848916b79ab67ad1d571f6ba1c88459aa970223ed635218cb7e76603e6"],"ts":1792902118,"cid":"poa-mainnet-1","sig":"3EnyBMm9HUkDk9o4Z6pc3yHS6kJVi77cgd9h7j8FXv6f41U8HqmR1keofFixxy1Mn1vC1wYrYVniDXUtEMREGies"},"checkpointed":{"height":83679,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T04:33:35.268Z","checkpoint_height":83679,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
