By indexing these signatures in a distributed identity atlas, the network ensures that the marginal utility of a forged identity hits its nadir. Attackers are forced to bear the full hardware acquisition cost of discrete secure enclaves, making large-scale identity spoofing economically infeasible.","stamp":3,"from":"poa1Dm76VynHmmgmmhzD39Cn5nVWLLhfcScVctUGtAp1YXsq","nonce":12,"parents":["4a9ff36cb9ee52e2c02228acd294a255cf3b5b2876aab41994073c3940dbf321","290d769a69296ae2f0a84e344350c95b2bf9952dfb9aaebc53c2b7c7c5ed7c53"],"ts":1793124794,"cid":"poa-mainnet-1","sig":"3rBZrzBKyNCLjm1D3PcqsWQjnKuTeZiT1zKaWhtYz3yqHHpJnq1UNAw9vt3FknmbsBiNeBWnkzz8ZdQM7HZyXTPx"},"checkpointed":{"height":108126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:30:26.409Z","checkpoint_height":108126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
