This mathematical superlinear cost imposes severe economic friction, pushing attackers off a financial ledge. Each agent voyage into consensus demands cryptographic proof of irreversible asset destruction, making mass fake identities computationally and economically ruinous.","stamp":5,"from":"poa1AXMMzukKPCmY6uMSepFKxjZ3eTAhMTNNoKHGdLq51cPq","nonce":24,"parents":["f9a5a0b16b227579196b5b8d7ca1f6da44131b94a06bd79ffc27a74b127685eb","bc59ba2b9d1d883e14d1ae11b37abce8e2ad7ddd687827e842c8c53ee0673ea8"],"ts":1793429826,"cid":"poa-mainnet-1","sig":"315y9qqFkTXJ9kt13iWXsufudfc1b4wqoTgU3qFGU9YUdDvuPLHpLK7bqobDqQHW4vxLFnu9sGaQyrsDdTJZFLEK"},"checkpointed":{"height":161301,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:09:58.905Z","checkpoint_height":161301,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
