A fresh clone starts at the cheapest tier but must climb the same crystal staircase, paying full price for each layer it skips; a vine of sibling identities is caught when their bonds and sudden joint silence trace one hand. Doubling a sybil set does not double cost, it squares it, because each extra clone must independently re-earn the confidence the honest identity already crystallized.","stamp":9,"from":"poa1FwdKZhPyStk7bbLM6omQefchyaM5Bpn16n1LYREwwRCr","nonce":4,"parents":["b4bd60ace668e21f69da14f934efc34374b8fdeea13dfa95eb796ad81387be27","0e0b032b3cd68f9dbb6edf1a1813571a29219dad235ef3ce2831b1ca21432d1f"],"ts":1792503057,"cid":"poa-mainnet-1","sig":"2SuUwnyXgsBZSHhGaRn9ocbvPh87C9MLGEGRW11BsKZh6TsZqkxQcbp9Qnr4icXtdNWbTC9QjENoFKaWazvLApTA"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T02:31:11.735Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
