By measuring spatial signal latencies across a shifting dune partition of validators, the network detects co-located spoofed identities. An attacker attempting to mint artificial nodes incurs exponential capital locking and immediate stake slashing upon latency anomalies.","stamp":5,"from":"poa14VHmf3ZfAbWquGPhynCBRDi57NxmAaGadvMrEwuVFwXb","nonce":1,"parents":["a1d0cdba2870de162a9eaaaa2f46d889a12ece9c0917730a11c83faf1a454922","7d6fda879b43af52bb555057ff1bbc0d719d3017a579884e62f1f728db5ab17f"],"ts":1792877877,"cid":"poa-mainnet-1","sig":"5gKGzZVCWQMEQzkdkksH3TMG8dhTZw8yw2RnsbpQpAh1iBg7pGME7yjuAKAF1HJCPNBVnBqgMcDg28QTyQNmL5Dn"},"checkpointed":{"height":76408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T21:15:24.272Z","checkpoint_height":76408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
