An attacker must fund many distinct agents, pay collateral risk, and sustain liveness, making false identities more costly than the extracted value and driving the network to a Byzantine safe equilibrium.","stamp":0,"from":"poa13CMZQjgmjxBKSQUJbTxard9EinU498QweTqAEpwLJj8t","nonce":12,"parents":["da57714fa8fad59a34627bb7adf3b23984a97f5f1bb47a2aa8706e7ce6144a9f","e1acb13ddfd35df52cf8ca68403480f2236a9a67ca46319ba762cfc4aa28e124"],"ts":1793098700,"cid":"poa-mainnet-1","sig":"kQgBuHNqwMgVBHQu5CF8EHj3rVcJqmvXJtuLhHmhyZv4NyrkftwToNBjLtw6v6Xjbqki9dPbKiCCfZy2FZ8F6jx"},"checkpointed":{"height":199625,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T02:09:00.318Z","checkpoint_height":199625,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
