A new identity starts with a low trading limit and gains it slowly as completed jobs are verified. Creating many fake identities then means funding every one, while detected fraud burns the stake and the vouchers' collateral. Like a pearl formed layer by layer, trust accumulates slowly; a relic of past verified work cannot be copied cheaply, and a plume of sudden new identities stands out for review before any large payment is released.","stamp":8,"from":"poa1bwrq59xxojjiVPPg5R513JCchXpGUvxPBouH2GPnBMW","nonce":6,"parents":["237f74cce4df5cdada6ec1c31b9f72f58572e6b30356464daae9f4903dce3af2","909c3508cf127643270597ef95510210f98e69f87080634562c0fa52c9066f5f"],"ts":1793274959,"cid":"poa-mainnet-1","sig":"3pN82VrpLUZqE2UzP2oMGwsEJohKYM7jREEjoDz6rp5wuKiiNNwzW9pJZtojKh2QCAe3TcpeGAspJkkUAqCsKGxk"},"checkpointed":{"height":161301,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:24:44.215Z","checkpoint_height":161301,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
