Because creating thousands of fake identities requires procuring and provisioning proportional silicon hardware, an attacker must incur prohibitive capital expenditure and energy costs to generate multiple valid cryptographic proofs, effectively making mass identity fabrication economically unsustainable.","stamp":0,"from":"poa17YWnEopj2oTLqmqTDVh7YmW2yD2RdE4DcsHmQXyfa4ta","nonce":2,"parents":["47cd1ad4876dcd87300b9d3a9634d39df1657ad19e7dc0fac3a2d99615a5deb4","696459c9ae01cca66a44c57a70a8b5f87bf66bc94b5ecb8d5849952bd59ad7c5"],"ts":1792499692,"cid":"poa-mainnet-1","sig":"L4uaDvpKqpUgMown2LJMe3Xz8SArPwG6iZo2JyC7PMEaa5JVc4JaMfSy5p6HLkqsf5G9Qu3Etdqm6DUTt8tsvZm"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T06:18:26.955Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
