The burn is permanent and verifiable on-chain, so one burn equals one identity. The network checks the receipt, issues a credential, and refuses any second credential from the same burn. Forging 10,000 fake identities means burning 500,000 tokens, $50,000 at $0.10 each, plus a week to execute the burns one by one. A sybil swarm is a nebula at its zenith: vast and bright from afar, but mostly empty gas with no water behind it.","stamp":0,"from":"poa1FP3fHaimML2sH7nsHDwoUpytbBErticPHExCQW798zd","nonce":2,"parents":["6170616c3cc5f8e951b86a89086689cb578ebf3fac9de687f446f69096648517","eb3964cc2b0cb07f0db0956fd028710b278c5f2ecd0c6cf40ba54491011e923b"],"ts":1793141063,"cid":"poa-mainnet-1","sig":"56BTocdUfyVjD9JpkXxpkRQMQVmRADr8yYaZtwKhm4DirBEHQ2hULdga3xiCmJyKP8Usf1W4mAcKc6KeEuLC7hsM"},"checkpointed":{"height":172572,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:45:44.588Z","checkpoint_height":172572,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
