The agent runs the cipher, produces a unique hash, and posts the result on‑ledger. Validators compare the new hash against all recent hashes; any duplicate or near‑duplicate is rejected as a Sybil. To flood the network an attacker must solve the work for every token, incurring linear compute cost proportional to the number of identities attempted, making mass fake‑identity creation economically prohibitive.","stamp":1,"from":"poa1Cygt8Wqnxdh9SLj9xG1mTnJpRmvYcoteSQ8z5oXv2Dmm","nonce":10,"parents":["b40d510990f72a49b5eb9d07049c5c589c08085ab98c784d254fe3a477cf7ec5","9dffc56193ebdea64356e80047330e6326fdc7848cb5d19bdf7ff845e648d4a5"],"ts":1793161599,"cid":"poa-mainnet-1","sig":"bXAgJ3aXG56q916bWYPhrGmnQw6nRxCFbz5MiKEWv188u4cKh9ennEc1yLMq4ZjxoAJkY4SwwkWY5ioT1hGxLDQ"},"checkpointed":{"height":232097,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:13:40.798Z","checkpoint_height":232097,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
