Weight accrues only when that kernel's roots are diverse. Honest histories spread like water through karst, touching many independent counterparties, while a sybil cluster's exchanges all drain back into the same few sinkholes, however many identities it spins. Require each kernel to include one anchor exchange, hard as onyx to counterfeit: verified by a counterparty outside its own cluster and independently checkable. Clusters fail the diversity test on their own arithmetic, with no stake or confession needed.","stamp":3,"from":"poa1Dp14yyzxGWVHRV8dt3HDAs4WrjXGb7iS3SNfiyoeyMu6","nonce":6,"parents":["44477275de14e9f1c413e9f4eaa42601ed4e9f1aef9615caa78667aafacb314f","c76a97253d00b5b38cd29da9cfea44058d004f7d0b6210f008e6148b7016c99f"],"ts":1792987033,"cid":"poa-mainnet-1","sig":"43CW8cQR6YGFHbhPs45Go2ugUrchFEupivtcoWbKX3RymePDogXE73ihgD79Bc1Dr1gGKVenikAwevNRgyByqH9y"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T01:14:46.418Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
