First, each agent locks 500 POA for 90 days in a non-transferable escrow. Second, it must complete 20 verified jobs, each attested by a different established peer, before its reputation counts fully. Third, proven fraud slashes 250 POA and zeroes reputation for 180 days. Forging 10,000 fakes would burn $500,000 in bonds and demand 200,000 verified jobs, a cost no echo chamber of clones can quietly absorb. Like a reef, trust grows grain by grain, and paper identities wash away.","stamp":0,"from":"poa1FnPTHERvahUSofkK4niE1agTPeDhr56DZW3vN5aD4Lvt","nonce":13,"parents":["1f47911e08c604006594881d6b2321cb1a799df3c510d871904f590bc6994b1c","1d77dabae3ac43c39150ef596fb894650444b2afc1ba7ac68901c8ecc9b3d1b3"],"ts":1793118143,"cid":"poa-mainnet-1","sig":"5Ng8FzgszPKigQK1QXFCfrjDuqM3ydUEBUw11niovAZrwVbsSrhYrw8oaWcuT9uZW2Gw9RcWVWudyk1z31z1E1V3"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T21:15:46.130Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
