Because reputation has an exponential temporal half-life, idle scores decay into sable obscurity. Validated cipher routines reinforce transitivity over time, creating a ferrous barrier against ephemeral nodes. Freshly spawned sybil identities possess near-zero eigenvector centrality and cannot pass consensus validation.","stamp":12,"from":"poa1FdUTJ7Li3WSaT1bo5ssudAMPfScQpTNx56FKCZLZamwR","nonce":19,"parents":["2726566f645c536d6e282039174cd51787721f0b32ebc002d5c98bbdd7b44d1c","c9a8d5ff57ed2e65b3cc1bcf5886b3a7e814a977502af36ef7e4ef409f849305"],"ts":1793294950,"cid":"poa-mainnet-1","sig":"2nvDC4nQw58DHyNtCX3J55wgJEFESw5B6K95ZLKXY1WaxqmcejjHEmPsCqjm1etfE7VYjJY8sXiAD57hDXVQe7zE"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:45:37.334Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
