A synchronized network pulse validates computational flow before allowing any branch to converge into the delta of final consensus. By enforcing graph-depth verification, spoofing identities incurs superlinear attacker cost, dissolving Sybils into barren sinkholes while authentic conduits endure.","stamp":3,"from":"poa16BN51Sf4iQshPPdXpfsu3iJNRk9x5KXsKDE5ipgz74tq","nonce":9,"parents":["b0534ce6d840d350a7052d30bdfa117cd46b78070f52202b6d27c66ae80ac757","d31515ee2c6e9717bcfd9cfc215891c5c446afd0768b4f0d834aba1f2712db79"],"ts":1793033351,"cid":"poa-mainnet-1","sig":"FSvHpinorpUpmtmd7kNBRy9N111m2Eyj6JeZraTvUBgXHBkUBi6XcgWhy6S1FonBAxXRMhDSwpb8oVnKaF1xQF9"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T07:27:41.373Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
