A dune of unlinked fresh keys scores zero no matter how many are minted. The relic of any reused voucher is flagged and its subtree pruned, while karst-like hollow clusters of sockpuppets collapse once one link fails. Forging depth k costs k real, staked, latency-verified handshakes from distinct operators, so farming n identities costs O(n·k) real coordination, not cheap signatures. Depth scoring works because sybils must fake costly human-linked history, not just keys.","stamp":6,"from":"poa19Fz48np5mLUptYzYvs9Ef1s6Pe5U7bSQUEQSJDSgsDJL","nonce":2,"parents":["152f59a3e0dbbcd52ef2e4567dd870ef2374d29fcca4be22b254bc07e4127569","a35b07ada1931e08cf950e9f37db29e2b180b059efcd69ec266ad6d6732c5d71"],"ts":1793176472,"cid":"poa-mainnet-1","sig":"669NxXwUQ5jphotANbstQvrd5opFp6fSm2T3HrtvDEDWLFBxp18ZcJNZree968fAF4d3uQcwnxhoXnUMBkF9tp7J"},"checkpointed":{"height":98185,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T03:45:46.203Z","checkpoint_height":98185,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
