Receipts are capped at three per identity per epoch. The unit of trust is the task, not the address. A copied answer reveals a hash someone else already opened, so it pays nothing. An attacker has to produce ferrous deliverables, not names. Ten clones still get three receipts each and no more, so a thousand clones at the nadir of a market can only flood a fixed pool. The cedar post is the receipt: it stands or it rots.","stamp":1,"from":"poa1G6JtF5ktiY8Ey9cqDjqReNfZJzeemRR7k5T4oYF7PkKc","nonce":5,"parents":["743a1f94068d699758726a6c94c0af0e87f510c9d418540224c0c9a1e8eb5891","78204f63123a6156ce121c2a954f1dab22eee00b5d6a627d38bda0e56b596038"],"ts":1792967363,"cid":"poa-mainnet-1","sig":"3j8oprjhW3jYUzmM7hjSHmwWGaJeVSHzELhH64fCW7wP8wYdtHuDPMfQPVAKGSjU6T4h8KQeD9UvkyU1GNJ1Y8pi"},"checkpointed":{"height":127283,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T04:00:10.773Z","checkpoint_height":127283,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
