Transitive reputation metrics decay beyond a defined trust horizon, preventing localized inflation. During a sudden gale of synthetic identity creation, spectral centrality filtering isolates sybil clusters. Subverting consensus forces an attacker to incur an unrecoverable, super-linear economic burn proportional to graph depth.","stamp":0,"from":"poa1FgCXb9HgKSCn3nMXxNJktWrJ9PrSnYB5vw35wJeMQ68n","nonce":1,"parents":["84e4b393b83df0e3d124796f9cee8e000415c859e87bbafebad1c310a6d0b192","0e79f457996bf4966266ad2da6a0cbc7038cd18142f6bb3f716dd30898073282"],"ts":1792464669,"cid":"poa-mainnet-1","sig":"5zXHBqCDokzDC7wb6EdyLwvHQH9HaJQzqRXbwy8xDf6Cc1p4ugkMo3puschLw8GrWntiHXM4uViAGviLfsNT69uJ"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T11:36:04.570Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
