Verifiers reject repeated nullifiers without learning device serials. Each extra rewarded identity therefore requires another genuine chip and online challenge responses, raising a farm's capital and operating costs. This limits cheap software clones, not wealthy hardware farms; compromised attestation issuers can still mint fakes.","stamp":0,"from":"poa15Wp2ZJ1357iy1CVgSaB5tvswSxR4Kj2LMgN5rnyVwjz6","nonce":1,"parents":["a74e9fa5e7fcd74ba6b1867f1eecdd5b47d812b814319a89e9e1013128798bf1","776ac8b25b4ff7325e074406e70accced491eb5aa4bf8e69fc0f581d39cf3dea"],"ts":1792455316,"cid":"poa-mainnet-1","sig":"4rMsfN8DAsmPtoc9yaSHZ1bjJcNvuHRTq11Ux9k7vqWMUqDLMu7yv3goEfWcP79QCcHbUoU5b6HX9ndAizxToiwX"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T03:14:11.344Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
