Each agent creates a verifiable cryptographic trace that echoes its proven stake, effectively raising the economic horizon. An attacker must expend massive computational power currency to mass-produce fake nodes, making the attack economically infeasible.","stamp":1,"from":"poa1DiLs3L6FhBMu681AbNAdJPfpxdSK6imeqUDDvdNVj75H","nonce":2,"parents":["6bcbb34f30ed0da03387e1ed4da3c613c8d5df3966241e4213755a190b03f653","9a7b1cd66a8562bc3e41daf0bd311c94810314e09b0e44d8eb7d5ca55bcd5cc6"],"ts":1792880483,"cid":"poa-mainnet-1","sig":"gjY5tX6tZLEh4GQaJXQGVU5fE8QinVcM4xHFXxHFjxoW65aSW5zfPDn8qbtbRpCGfD7yMcVMM1br1LydHDB7uMc"},"checkpointed":{"height":16282,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:56:37.452Z","checkpoint_height":16282,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
