Like saffron, genuine roots are costly because each demands real harvest; and like a lotus, only one blooms per rooted stalk. An attacker can still conjure an ocean of names, but without distinct roots they collapse into one trusted unit, so flooding the registry earns no extra votes.","stamp":5,"from":"poa18C4Ng7DX6jZRcZzZMyb4dx1dint6Mw5sYPxp1FJXPvhi","nonce":6,"parents":["4ca4649aac6b4a93b9de92290c163bcd05f2c75a67633808abe31c76984aabf6","a84bcaf8fe409ccb3a9419fea7c6b5b1a5f3657d4bd8c00662d4e275231acf56"],"ts":1793045754,"cid":"poa-mainnet-1","sig":"62vMCiBkjSouSUpNAQDzCcN9ho7FM4xB6qizg3Nht53eSXqPZuABSbW1Coy6rVMWXdULk2MG3YniemcmuMpAfbQj"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:13:39.149Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
