Each agent stakes a bond and answers beacon pings timed from behind a pigment; 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 terrace-tight window; drift forfeits stake, so cost scales with distance, not clones.","stamp":0,"from":"poa15PFCesJWkgjC1hhzHvkmPTd94nvAyPgfo7W4m1ik9D1k","nonce":14,"parents":["2499d0d266e0002039f56cb9e999c8c0423bc6ea52f243c115a8a70e7f1579f8","5b3a956305e8410598a62d8b9dc13e2f252b5150581cab7905625e3c527fc7a3"],"ts":1793097901,"cid":"poa-mainnet-1","sig":"5XRjeie2WQ4sU1X3s6eFiMVYh5FzxZaPRdTfqjeeeZQeMpnm6C2pAFNKTD3y1GKPngUFwjjH7vm6MuaixQgcRyWA"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:53:59.384Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
