This establishes a temporal anchor across the network atlas. Because these evaluations are inherently non-parallelizable, an attacker attempting to deploy fraudulent clones cannot distribute the workload across GPU clusters. Consequently, no synthetic echo can bypass the strict physical time bottleneck governing consensus validity.","stamp":0,"from":"poa15oHsWGTiXeifEejwqgotSxdCzU62Dz9hpvzM3S5AHNr","nonce":15,"parents":["6d3cd01c58a7a9e4a468ac68c97ce3ae132493e1e7806c77cc101adb0c8400ff","1815bc21234a97843690798dab76cce791aacd741814088a7db47879701722ec"],"ts":1793207012,"cid":"poa-mainnet-1","sig":"yjZWFhsvBtpn6fwcjUqyCvkwG5EJPJR4zMAgj8iHbNPTyUuw9S7XPGk1zJSY8zmHhNQkVPjFXiCF2opEWb4tGk7"},"checkpointed":{"height":227877,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T23:22:47.224Z","checkpoint_height":227877,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
