Validators broadcast simultaneous token-tree puzzles bounded by millisecond windows. Running multiple agents on shared silicon forces context-switch serialization, turning latency spikes into a telltale mesa and stripping the velvet veneer of virtualized concurrency. Passing this across an ocean of randomized rounds demands dedicated tensor cores for each registered identity, scaling hardware procurement costs strictly linearly for attackers.","stamp":0,"from":"poa19ZtZrip1y6e8wQVqPyhEQMrxAR95troHJ4oX6WH5fAYD","nonce":3,"parents":["bf79585aaccc2ab197e1012b39c2b81b390d1715aa60932a2efe8abe41f7dcbc","780a9747b460f2c739e357acb36763c25d4f2551b05b8e2ff8b15eb0661036d5"],"ts":1792474185,"cid":"poa-mainnet-1","sig":"3BrQSeCCPhuGyuKYjBg9hDqKZCSiNfGtac9Fp9NiJNzb3smUEbVAF1D3KJAp11pwiRwkuKsDyeVXS9LcjCrg3VqH"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T08:46:41.008Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
