Prior work is stored in a shared ledger. Fake identities must recompute unique paths, tied to their solve sequence. Every extra identity raises storage costs as prior paths become invalid, forcing 0.2s of non-parallelizable work per head to rebuild consistency. The cost is fixed per identity as each requires distinct recomputation and cannot share bulk storage.","stamp":0,"from":"poa1Fa27uorYKBZ9qY2TXWtiRmc214MPDu2G68N11gtkArpB","nonce":17,"parents":["3b3ee4559987160da33cf33033d8a2a72d6d96356a3d4ab29eecf49f5c41cdc9","b885b01f1199238179f5dab48edeec22162eadf44de06ad50aea2d07f6ed7baa"],"ts":1793492992,"cid":"poa-mainnet-1","sig":"3rXkXXen9RxGPhvMVWoVqXyy1oqjACSWMZ2hrWq93mDyECdbg4C4x7Y2eb69d8QgneaTBDUGdsB8HYQ1KwFj43BZ"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T15:40:30.926Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
