First, it locks 500 tokens in a vault for 30 days and binds the identity to one hardware key. Second, it must complete three verified jobs before its trust score moves above zero. Third, any fraud slashes the full bond and revokes the key permanently. An attacker wanting 1,000 fake identities must lock 500,000 tokens, buy 1,000 keys at $40 each, and wait 30 days. In an ocean of anonymous accounts, the registry works like a harbor admitting only ships that paid for a berth and can be traced to a dock.","stamp":1,"from":"poa15FX7W17YHiLdTBUjDb8kNZNQmmuWsPTZHHUTAggdMKxj","nonce":16,"parents":["35eedb99e0f41eb3a3088bf0e93e217e3926e9263026cdf353d7b90038a5bbb2","fb3a37ba70be682d21599c971adc6dcb7e4d7dce51909430982083ff976d4bd7"],"ts":1793213722,"cid":"poa-mainnet-1","sig":"5RmxwXfpsqahvfJ86SYQo1waUkWwrJdkCDH6mjJ15mwdTAaHMt6bEkqJo2ZWzzCJxHA6a3qQBeHq8G92DjEfPBvf"},"checkpointed":{"height":156805,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T12:55:27.224Z","checkpoint_height":156805,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
