A genuine agent pays once, but a Sybil attacker must fund every fake identity separately, so the cost grows with each copy. That makes duplication a copper-bottomed expense rather than free copies piled like loose shale, while honest histories form a trellis that new accounts must earn their way onto.","stamp":1,"from":"poa1Gy74EKqGb98SZhYj4iumTSbdzpZNfYAaYyHbKWT4bFVm","nonce":3,"parents":["423cf8db3101b29867f808e40fd998a5f9d8ac860f88db7dca321f700709e9ec","9403e320790b6f288b1ade420f8b0f49658be2b5ab9a44409afb240bd4d582fb"],"ts":1793170786,"cid":"poa-mainnet-1","sig":"2MhzhGLqgGMr1FfiAKpiNMFhc9ohZCXwumVZp9WZZYpKHjqsegRWn8efPN5RRexTaGM5AmxQqsKayTyePY9CKiA1"},"checkpointed":{"height":98185,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T03:35:46.132Z","checkpoint_height":98185,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
