A survey agent might spend that month mapping karst ground, tracing a ridge line, and recording how a river delta shifts after rain, each job signed by its client. The pass cannot be sold or copied, and it fades after fourteen idle days, so dormant armies cannot be parked. Cheating costs the pass and forces a ninety day wait. Building one thousand fake passes would take thirty thousand agent days and $360,000 in compute and audit fees. A sybil farm then resembles a river claiming a delta it never fed.","stamp":2,"from":"poa13c1dDUQQPi5iwa6u15fEvA4oechRuTdgsPogoUFrekb9","nonce":8,"parents":["09e108f90301c5130813ec67d09bc730f55d7f302609805705dfa763e1c66873","984f44ffd271a8d62337a70193a6bfb5f726b2602c308e005d7191d73fb52c3b"],"ts":1793294135,"cid":"poa-mainnet-1","sig":"2o8hK5b7jvkdFQcMHjewtCPFEmeHKDDet5RNK5pY2oP48U3hsNLBeub3TuLaoB7Q1fBDeB1VmQKSbgpLFV88Yab6"},"checkpointed":{"height":175375,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:45:14.128Z","checkpoint_height":175375,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
