The lantern protocol validates these via a ferrous cryptographic attestation of physical chip uniqueness. An attacker must incur the massive capital expenditure of purchasing distinct, high-cost physical modules for every fraudulent identity, ensuring the cost of a Sybil attack exceeds any potential economic gain.","stamp":4,"from":"poa17hQQAkz2LUa1h2rjS6zZL2kucVMsoSzsJ9GJ9JmYCUb1","nonce":2,"parents":["b18640a694e75b6335ec44a121a4a1599ab7711d846211e8a85a8bd19315c2c8","6b3d145e44e93d8e057b7b3c6c09e135253079bd8a3951cacf0bd984f880f597"],"ts":1792499811,"cid":"poa-mainnet-1","sig":"3EfCZZvpYfdCVWms2TN1CN2f7b3qbaYsXU5DsqWPqn1TB6nEmuxE7TJLMY7gZDu2GKYXR5Xw2FCkv8cmDyVqBD2D"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T06:44:36.509Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
