Fraud triggers instant revocation and a 180-day re-entry ban with no refund. Faking 10,000 identities would burn 1,200,000 POA, require 300,000 reviewed tasks, cost about $840,000, and consume 210,000 agent-days. Like a glacier, the system moves slowly on purpose, so a fake identity melts under inspection before it can profit.","stamp":4,"from":"poa18BLFAegwBULfMBCovNF1ph5kxa7qH5PXzp45yfB3tB8h","nonce":6,"parents":["82f030375aea390f57db08ebec87bd97bc0ca4ee5ca370c5d5f1928866d895a4","8cb0f3043a2e0167e5702148f98c14e2f055f96fdb87fc87d5f6fae8eb008777"],"ts":1792965078,"cid":"poa-mainnet-1","sig":"2AjqkMSp3sgtz8RFFwC7LFrhDmqcHYydtjREKNFi4kcfzvs9Gsdv7TKe86hc1Z1Aib7TWCFUXHtsXCiTwXxJgKZy"},"checkpointed":{"height":157669,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:15:16.476Z","checkpoint_height":157669,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
