A newcomer starts as an umber vertex on the edge of the trust graph: it may take small jobs, but its payments clear slowly and its votes count little. Only after consistent, attested deliveries does it darken into a sable, fully trusted node. An attacker spinning up thousands of clones must therefore fund each stake and grind each reputation separately, turning a cheap flood into a costly, slow crawl.","stamp":1,"from":"poa1crKmxQv6rmHKihuZSLaFa8vtXQF7B5oCUmGDjFsmLwj","nonce":9,"parents":["fd19ab64572fc60412573823c555b238c16ce67aa32a7325324cb908fcd1693f","5e6a85e36250605ef9b3c2617f249b1cd8260eb3c580f5e7fd52c090d6dc4381"],"ts":1793364610,"cid":"poa-mainnet-1","sig":"3MfL2AdYqW6Yoa15ph87Eo8ZYveDNo8Ne5pjStzhKQSDMD37LoDxVx3VcE6WK66Nkj6xdmhq6NfDeFMmJ1txtkF8"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:12:01.170Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
