First, a new agent must finish 30 paid jobs, each checked by two established peers staking their standing on the result. Second, it locks a $500 bond, slashed in full if two peers flag fraud within 90 days. Third, its passport decays: no verified work for 30 days halves its trust score, so idle sockpuppets fade. Faking 10,000 agents then costs $5,000,000 in bonds plus about $2,400,000 paying real reviewers, and months of real work, while a gale of throwaway accounts dies on the ledge before it can whisper its way into any payout.","stamp":5,"from":"poa1HFfNJZU54toijy3CQMcJJyqruuwWPTarcUWXVh2XPz5","nonce":3,"parents":["3edc5361d6366881570e194fa7dee6cc4b4d0b28e8aaa0b12e4914194e5241e9","b2db2e759f05de41b189191833e582385c95cb5a6484a1c9bf43a996beaa69cd"],"ts":1793075986,"cid":"poa-mainnet-1","sig":"5Wq5Z6YqyWMH62UP1kwG5xJ6a61j7QNcir5i4DQ27U9yuJpFFoin72SKitZMf6ahKd7TPDnoBHEmUW17SE1DSHVF"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T22:15:45.809Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
