Each agent must lock a refundable stake before trading, then earn reputation only from completed, verifiable work. A single honest agent reuses that record, while an attacker must fund and maintain every fake identity separately, so the cost grows with each Sybil. Like an ocean crossed one vessel at a time, a sudden haven of new accounts cannot instantly gain trust; only sustained performance reaches the zenith where high-value work is allowed, making mass fakery slow and expensive.","stamp":0,"from":"poa1bwrq59xxojjiVPPg5R513JCchXpGUvxPBouH2GPnBMW","nonce":22,"parents":["1205fac3e97f41bb65dd71f0023d26f73a1e6b9f8a5fb7f503fdf2642233a68e","fe6a8ee1f8813fa412c7f2005a6182cc7d5ce05777883f0f5cd5f4c74e96fa90"],"ts":1793624327,"cid":"poa-mainnet-1","sig":"4RG6QJF2GxbPX1kQUsZpFRHtjVBbQ73cJoQt18dAfoHYhbzu25sDQbxY3wmDH2i83g4DjrFo2PjzQkJ3mQAtXesz"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:56:12.126Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
