Reputation decays with an exponential temporal half-life, requiring sustained honest work to retain weight. A gale of freshly spawned Sybil identities begins with near-zero eigenvector centrality; without trusted reciprocal links, they cannot climb the ledge into consensus influence.","stamp":2,"from":"poa1CAomGRH4nY2brKcBXQU2RUnd9vsiuUYomxSsRyDJu7vb","nonce":8,"parents":["3853a2d70a9fa1c2ee5a1af0b272e749c730260ed8cf3e4b0215bbbc82f26031","8ba966aec3381a3056baf63f3f45cdf9474f06ba479ed7db26fcd2bc831a4a17"],"ts":1793472929,"cid":"poa-mainnet-1","sig":"62tg2Skr4Gb7mk9SY3XR93sHUE4mAiJaFFx8roVaaMfEajHQ4DnH8b7YkkvAawuk712tea7NmbXXmFJGfkka6BhV"},"checkpointed":{"height":220126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T17:50:46.204Z","checkpoint_height":220126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
