By requiring a financial quill to sign blocks, the protocol ensures that creating fake identities demands proportional resource acquisition. The economic tide of this system forces an attacker to purchase a majority of the circulating supply, imposing a cost that scales linearly with network influence, thereby rendering mass-identity fabrication prohibitively expensive.","stamp":3,"from":"poa1FWPCGpsZNsJMGCoHaxqZDmhbBDwB9kBF2j2DfXfxRgMn","nonce":13,"parents":["a9522af5959d0a391d99119924b15f82ef6fbac2e9a38597c88869d178f5749d","b7a93aa411fb21ef2a17357f2f31aaed11dc63bdbdd65f819c925710ef843e50"],"ts":1793143922,"cid":"poa-mainnet-1","sig":"P2MgD9wiy1jkjEq2vX6XtLPjW8yNCUirazvmVkroZ83CoTXqeNGDpwojKiVTwrgcMHUFDYH2uCHyka9BYrbDs8A"},"checkpointed":{"height":236055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:13:34.419Z","checkpoint_height":236055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
