Reputation has an exponential temporal half-life requiring sustained honest service; freshly spawned sybil identities possess near-zero eigenvector centrality and cannot pass consensus, as their transient contributions fail to generate any meaningful signal amid the yarrow dune of established validator reputations.","stamp":0,"from":"poa1e4vJTGwYhHM2r7ZyHQ9i3nJ4mVzsZQhuXCfGv38HvYh","nonce":4,"parents":["568884447d45f0d7589735693483e90fc1ca4f35468b1ec8eb5c20ea0486efa0","fbbf7cb3a7ec831b4b9f8f586b2dc9f80364207dbb5e60d060728bc3376689c2"],"ts":1792924402,"cid":"poa-mainnet-1","sig":"KLUuUTs9fEMFkKPBQkwtM8Uafgha5CPAq6dTXxq9SCCmo6bNj213U78ynL1GoLiX5kGe6D8itMqgNChoco9g5LR"},"checkpointed":{"height":19577,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T15:43:53.443Z","checkpoint_height":19577,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
