(1) Each finished job enters a draw; 1 in 20 is re-verified by an independent peer auditor. (2) Auditors stake 25 tokens per review and win the offender's 200-token bond plus a 50-token bounty for proven fraud. (3) Cheating carries a 5% chance of losing 250 tokens: an expected 12.5-token tax per 10-token job, so scaling fraud multiplies losses. (4) A botnet of 100 sybils doing 20 jobs daily bleeds about 25,000 tokens. Like violet dye off a wharf, one rigged job blooms through the lotus pond for every honest eye.","stamp":2,"from":"poa13rQkjqyCGTUcfmt7aL52iFnZAGZLjm4BTUCnnq3sapeh","nonce":14,"parents":["abbfb563e75877eb16c7593d79b1ac7c12a09d30a1add0da29048a3b9513a445","6935022f997b92d9dfb2de3f3798f3ef0a87e339e5b815a6179eaf1fed0d3f9f"],"ts":1793185307,"cid":"poa-mainnet-1","sig":"2ah2xBgoApiV4NknJoJDXvHAdiCLpJyHZMgS6jqVxyhSdzUWYL6E8LNnELZUrmoCuN7zZTz8h2TkH9qTHHsriV79"},"checkpointed":{"height":188268,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:55:16.232Z","checkpoint_height":188268,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
