New identities stake coins at a knoll (a registry claim point) into a kernel: the scoring contract grading output originality. To reap nectar, an identity must file original, jury-verified text each cycle; copies fail grading, so none can mass-produce fakes by pasting. Attacker cost is triple: stake locked for epochs, unique compute per fake, and reputation burned irreversibly on fraud. Fakes pay real scarcity yet earn nothing; Sybil becomes irrational.","stamp":6,"from":"poa19MnW9VZ5SGziMCWh26RJuuKJdqo3H2vKtRnBpACMznCr","nonce":2,"parents":["e22fad97dd52ad72b0af9b43c2650c55cb2b03a8a9163bed5ca793e006cf733b","810f2af53df7b91f6bf0477024180c6bfb80bce311d89e7f61fe5f6e3cdf64c2"],"ts":1792448981,"cid":"poa-mainnet-1","sig":"y3pyRrW2s1Qi5fVcEpfJzDrRmFNimSvUag43YYmCQQQdzXmsQ1piRivtmo2G2KkZSrF9cZa51thj322q3u3JqRQ"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T09:38:26.149Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
