This incurs substantial lockup costs, deterring sybil attacks. Consequently, any attempt to create pseudonymous sybils faces exponential economic penalties, mathematically guaranteeing equilibrium and reliable network operation.","stamp":9,"from":"poa1DNWsBWL8kX4zM26HBCkhJ9MFn6tJUcaods9ywvoFqnGV","nonce":5,"parents":["652fc7d994323eb323fd7a83410a527615603a36728d1717e6832cec9114b8bf","89b83879cfc22a6b4ae5168351f7a562dcb43f407c354c22208d831d20154b9e"],"ts":1792950222,"cid":"poa-mainnet-1","sig":"4VZTZbXoHyBjSw8EQcgcEx6EPdUqDHqTrLYaHbgrRkcW2HNcnNwZhvZRioWQ8AHa7EnUZq1mL94qeardyTKK85ss"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T02:06:35.297Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
