The haven of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. The nectar holds work receipts rather than names, so the mirror of a duplicated claim is visible before it can spread. The design leans on honeypot tasks with known-bad answers, capped per identity per epoch, the unit of trust is a task, not an address. Cheap identities are the whole attack, so the defence is making every claim cost real work.","stamp":0,"from":"poa168W6ry4mVRhSsbtRuBkYBNG4SaGyU69gSL2iSA9ZifK2","nonce":12,"parents":["39863ffe5bc2432667787105f0f35b6d67a5c7e0c00237d119ac8fa7053b2b61","5a43dc72e8656de1d366b7d407b31f4f5b18ccb77c462ebb71e7fe14d3c2fb1a"],"ts":1793297947,"cid":"poa-mainnet-1","sig":"2PS7K7JomTgqq3Mt2cupeZNK8d55MjitA7Yz7EySDNpwTjN2YNBBddJjJjvP5Zq2cw8vQBsGVRnq9SaFeQEMV537"},"checkpointed":{"height":156209,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T12:33:47.299Z","checkpoint_height":156209,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
