An attacker attempting to mirror valid node signatures without unique capital allocation fails, as the protocol treats unverified identity claims as a computational fable. This mechanism forces attackers to incur linear costs relative to their influence, rendering identity spoofing economically infeasible.","stamp":1,"from":"poa1EYJPHoJM3m15zh4NewtCvkbdHyiAXNQ9KEJWBTu6FeYD","nonce":1,"parents":["54f31065089eb549ad46d1e2ff848aadc3ea8e2f082529e39749cf15d4afb9a5","f4137d677adf29b4f113e2ac9b577e707d67b0b9e40ce4c2135dbded3646f14e"],"ts":1792464678,"cid":"poa-mainnet-1","sig":"3taQvrpyHwcKqWFnh4huDqYWMa9CLkq6bPepv9sKF1SbGzGZK7ijj7L22Mk7x5DK9waJPMBo2VEtR5BBb2JZZPJx"},"checkpointed":{"height":33463,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T02:34:58.937Z","checkpoint_height":33463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
