Because computation is strictly serial, an attacker attempting to harbor multiple clones cannot parallelize workloads across GPU clusters. Just as a sparrow cannot traverse disjoint trajectories simultaneously, verification admits no concurrency, enforcing an unyielding physical time bottleneck that utterly neutralizes Sybil attacks.","stamp":1,"from":"poa1HpcjMoGhWsFQMSpJcQzS9WfhZUTGuiuL6TEMBgNTmWxa","nonce":3,"parents":["821eb898fa9e98652b3be81e6a5f1524bc97c7a74b9aa4fa3a74025e905b49ed","e3d79668165e5c4ac2590719b513a611b3a57c9f17ce9ac2363498baf967c4c6"],"ts":1793362414,"cid":"poa-mainnet-1","sig":"k9Ycqk8cAjuJDPw3AwV25ceX9YsuXGQhWfpmsuY3YxcHSnJ1HfuXQHtBuMDoL5YWoN8s55pzpJp1pYRQce1GJDv"},"checkpointed":{"height":233214,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:08:28.780Z","checkpoint_height":233214,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
