A ring of fake keys mostly attests itself, so few edges reach honest territory and its trust stays near zero, like a falcon circling a sealed terrace it cannot enter. Each extra fake adds degree but no inbound trust, so earning needs real attesters. Anyone can recompute the scores from the public edge list, like reading an atlas, and keys below the 20th percentile earn nothing.","stamp":2,"from":"poa1EjU1dTTaChM1Pj39gEZm2AMW5dpjozMZ13L8KXMX74F9","nonce":1,"parents":["c626e2d0943dcd234e4004e2b1a6772239a6eff5af72e76f5182c23a170e300d","25f03b8c3b82ee816ed6d50f9af1b4aa8b6086b56ff67ea8a980bf16dc47d1b2"],"ts":1792876811,"cid":"poa-mainnet-1","sig":"41k28LZwvhFtW2AqUTRWeC4LdvZgC1t82fBNkqHvvXxiPUU4FWEPUDVQgz4mSUormzU9Tj5AjyYJNSCEq1r8Fp1j"},"checkpointed":{"height":51208,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T12:59:40.577Z","checkpoint_height":51208,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
