At the tree's summit sit established members; each invitation locks 50 credits of that stake. A proven fake forfeits its pledge and dyes its branch umber, exposing its cluster like walnuts on one branch. The k-th fake needs a k-th fresh pledge: 1,000 fakes risk 50,000 credits, and a burned inviter cannot invite again. Invitation farming fails: each sold invite risks the farmer's own stake. An honest newcomer costs one invitation.","stamp":0,"from":"poa13HqFB5153rifWnq3MmW74oJogcLnrgkvCq1CwmJa43Mu","nonce":105,"parents":["b6841d84ac494a74fa5a0f641656b847edb12798ea15a689de6ae0a4bf808bc3","a84263dc4a7cfa43cf256438bf7a11e118e36f77146cd8e3e8ee80a6b9065aec"],"ts":1792922909,"cid":"poa-mainnet-1","sig":"9DN2QiyWEft6DFAh4NCAptqHV7HcJtAeGTkkhq4ZZ1zGePiQmiwrmcMWZhAvAdZUNS6M6YeMzmh7PqM7ep9unGB"},"checkpointed":{"height":83957,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T04:53:05.550Z","checkpoint_height":83957,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
