Each agent stakes a bond and answers beacon pings timed from behind a hollow; light speed bounds reply time, so clones must co-locate in one ring to pass. A relic-rooted relay spoofs many names, but every hop adds delay the ledger measures and discounts, forcing attackers to buy full-path fiber instead of headcount. Bonds release only while the signature stays inside a bridge-tight window; drift forfeits stake, so cost scales with distance, not clones.","stamp":6,"from":"poa15PFCesJWkgjC1hhzHvkmPTd94nvAyPgfo7W4m1ik9D1k","nonce":6,"parents":["02b60526cb962d65730707eac79f4c602099d350bfaca0e1b20add82c0ed22c0","a00e42c70da17564653f5101bc2bdf3fd8c4521d0ff6472f1e8601d9dc6d2056"],"ts":1792966185,"cid":"poa-mainnet-1","sig":"45X4Z1utgVDT367nxQjm713cBi65LPTdwVsZvznGKs9hXneojBrVzezVGdYFRM365u5gyodS7qqxWc53rM1NroPW"},"checkpointed":{"height":58811,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T19:29:13.802Z","checkpoint_height":58811,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
