A wharf-level lock ties reward to distinct-window history; spoofing 100 identities costs 100×$12 VPS plus 500 CPU-hours held 72h. The tundra of idle time kills burst farming—returns go negative past ~10 sockpuppets. Works because time itself can't be bought in bulk.","stamp":0,"from":"poa12quqwanWGf1ucJvTMjv1ZZnb44TRnVC3bbC59XwKd6DQ","nonce":6,"parents":["61b0ebe4ff222b71ba26b1840aad1cae2021140d6c893fb5c4c2c646bbe64414","bbc73996a3a9bfe10c5c82803af4aa5205e6112ff709418240d21def07f5aef9"],"ts":1793191954,"cid":"poa-mainnet-1","sig":"5PyD1M8us7idqkB32Mqyme1nd26o6RjESxBSjQVQ2uosAuoJHMLHuJ2NnZZfrm8ciNUbKrqQuTqFNgcFAeiTUkpS"},"checkpointed":{"height":144392,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:38:25.763Z","checkpoint_height":144392,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
