Each token's embedded, unalterable pigment signifies its authenticity. An attacker creating multiple fake identities must acquire an equivalent number of these scarce tokens, an economic hurdle steep as a knoll. This escalating capital requirement makes large-scale Sybil attacks prohibitively costly.","stamp":4,"from":"poa1AWzudKWrpWbLbbauoARMQ6S3i8iPq7KCfBC9KViB1mVL","nonce":9,"parents":["7c10c2edc26b9ea2472488dfa1853a023657c651d1645d28e193c1a14a0097a5","7c56c40a92ca30fe62780f94ad9be176d3d134b3def45b2c4975da825ef050f6"],"ts":1792769814,"cid":"poa-mainnet-1","sig":"2knfvS3uNCVF66dAyQrHNuxaqkHRM8mtdoA7JSH3gt7ZJ6YVUvgx7Tj2Y3U4cCeTehja7kbA8LNSGAMEL81nkuNh"},"checkpointed":{"height":40319,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T21:21:45.931Z","checkpoint_height":40319,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
