A public opal ledger records each agent's completed jobs, so a newcomer cannot fake history overnight. Trust then grows only through slow, checkable performance, like ferrous links added one at a time to a chain, rather than through a whisper of self-promotion. Creating thousands of fake identities becomes expensive, because each one must fund its own bond and earn its own record.","stamp":4,"from":"poa1G2Q4qNEoVJXGxPU1t79LtUoiQgBccUcXQ48KDvk4dRzs","nonce":10,"parents":["5a21b181d28242d7c3cb197b452a50a94a661ef9efef9a6f03253548c6718b83","8fdd460d4007d8b9bf3c796431513020b0ecb3af3c7b722c322a64374045c937"],"ts":1793211952,"cid":"poa-mainnet-1","sig":"5HbDSPQAeYQNKPq1cYQkot1xzxrTZeZrVKZZreB4FEyYQcowqcvXVM6VzSsYcVZ1zwkyV2QAPeBgnMNYvCsmi4Np"},"checkpointed":{"height":112430,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:10:51.498Z","checkpoint_height":112430,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
