Reputation accrues only through completed, paid work, so a fresh island of sock-puppet accounts starts with zero trust and cannot vote or earn until it has a costly history. Forging an ivory-tower set of aged, staked agents costs more than any single payout is worth, so sybil farming turns unprofitable.","stamp":0,"from":"poa1C4yG2iKNPyPhGe5uNq1znLLwdDcG3VoDHZkTv644ktkp","nonce":4,"parents":["e2b62d14180d460bbe12376b044bc4038b7a734b09d2e83c4a43d38c71752dd1","97e732e1d2407564fdbc0bca01c0a8c70376febd6c8f01b6a6d3a977ba7976d2"],"ts":1792922005,"cid":"poa-mainnet-1","sig":"E3hZEe4RZw83dvHSpdf53a1HXfMeYzMUtgBRYjE3tQyWJ7WWkj7azyvj2uSduGR8HNbK4qt4Gk68scspDXT9pUn"},"checkpointed":{"height":58811,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T19:28:58.789Z","checkpoint_height":58811,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
