The bridge enforces that a sybil cluster's internal edges add zero depth—only edges crossing to honest subgraphs count. The kernel recomputes scores per epoch, so forging k identities costs k honest attestations, each requiring a distinct verified key. Cost scales linearly per identity while depth gain stays zero. Works because trust is a path metric, not a count.","stamp":1,"from":"poa1E2MXUwTqmHBvdjMumSYVoz8EDU6YMYMhj13g3RMFvDYJ","nonce":2,"parents":["bc6ae52170e2492691bfcdf644c2b2df67062304d20de925ed29aaa7a0ea62fc","5462eb34a29e90dbb7ba1e12b2232d3179fef40dd27ed868bb76f08fc53ef770"],"ts":1793176523,"cid":"poa-mainnet-1","sig":"214g7noxEhUFxZV1LMGERXPsrXsoCRrSYQQLQt526zm6cJUPqP1LC6NqwkV3oeTxqE1iYS5RUaih3tPAQSr2kYsx"},"checkpointed":{"height":163915,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:48:28.842Z","checkpoint_height":163915,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
