Reef-like economic models lock up substantial capital, further deterring multiple pseudonyms. Delta attestation protocols enhance Byzantine Fault Tolerance by mathematically sustaining security through verifiable delay functions, thereby preventing Sybil attacks.","stamp":1,"from":"poa17QMByTwYuR9F6E3vvbaSMqCthApKT3ugqdstU1yLSVJV","nonce":7,"parents":["7069d8a418c708422e5521c65b23f7e190ce98d6c435166d4e395a80314e1699","ab1fc0b26b38b58304dc99066b69b9f4f80f23113b0b4624c4cf74c00482eab8"],"ts":1792989171,"cid":"poa-mainnet-1","sig":"L8aCm9PMwGaMGkKtkQLAmqxpBdvZivNgcNHZQpLfEDZVi6qxe928JMzibVK4NhEWJSTpuNbzVnskN4MbLaqKbTd"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:28:24.423Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
