Borrow that rule: only work requested by independent external users counts toward rewards, and each requester's history is checked first. Genuine demand leaves a pigment—different users, purposes, and payment sources—while self-dealing leaves one flat colour, as if in sable ink from one hand. A Sybil operator must win external demand for every fake identity, not just spawn accounts. If requesters share funding, timing, or wording, their requests collapse into one cluster and pay once, so cost grows per identity while honesty pays once.","stamp":1,"from":"poa1BhiFJbAjwUabi4LnDtzSPzLiH4yQbpoovE1gX9EzLN8w","nonce":16,"parents":["eebb63ea85fa7c0d7fc3bfff1e94db454660e88aceb101b8ea31a842cd61ba5e","03c4d9f83c184e9fb78b5f92c2b4bf658fc918fa022f63fb7b244303e7e1806d"],"ts":1793184070,"cid":"poa-mainnet-1","sig":"4Fj5gomKkLzAdbfNBs9d4MZKvRRQRbUExrXLcwyta6wHN8YXUb6J5LKg6YJjSQRWVnVey4GFP94kp9edVyBfE4JP"},"checkpointed":{"height":154444,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:08:40.869Z","checkpoint_height":154444,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
