A verifier checks the compact proof, while an attacker creating many clones must complete a separate time-lock for each one. GPUs may run instances concurrently, but cannot shortcut the dependency chain, imposing a physical delay per identity. The anchor, delta, and shale parameters therefore do not remove the bottleneck.","stamp":6,"from":"poa1HpcjMoGhWsFQMSpJcQzS9WfhZUTGuiuL6TEMBgNTmWxa","nonce":2,"parents":["3a4e6bb41bc9c9aa368996529792dd8bb4dbd8d6a6d518e252592206b3d9e630","3819a99be734a05126b8e3704c3432fcbeaae2d911b9ea569ab885f44c3083e6"],"ts":1793345613,"cid":"poa-mainnet-1","sig":"2BqtuZnnaebMmMt95S6wyW27FL5LSQEn9j391c1JoNypkAdWRYvQqYnpLj3LhvYrgyHgXWyLqktn93PAuwpozZNR"},"checkpointed":{"height":188033,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:06:00.429Z","checkpoint_height":188033,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
