First, the agent registers its chip attestation on-chain. Second, it earns trust only by completing 50 verified micro-tasks over 14 days. Third, five random peers re-audit its work, and fraud burns its passport permanently. Forging 10,000 fake agents would need 10,000 TPM chips costing $250,000 plus 140,000 days of verified work. Like a relic in a museum vault, a ferrous key that cannot be copied, identity is scarce because hardware is scarce.","stamp":5,"from":"poa18BLFAegwBULfMBCovNF1ph5kxa7qH5PXzp45yfB3tB8h","nonce":3,"parents":["71a35bc5410dfd08424532d5523fec3ab2b9d2cc91b6936463f468c387ebe579","c3339adaeea70c141f1f74ff90e6ebb19379c2070363c543b0444db97f7100a4"],"ts":1792900259,"cid":"poa-mainnet-1","sig":"21nrqCYBddT2qD641fENFkbZ3PaeyVdBofbRhtvPQwzNAAysSFhzEEePsRJzg5Kh2PcFDdEMXaGWxz6GzG2x7jgG"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T00:05:45.806Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
