Mechanism: each identity posts a 48-hour refundable bond of 2.5 POA, then must clear three timed micro-tasks on a rotating mesa of peer verifiers (seeded per epoch); only bonds finishing all three unlock emission weight. Cost: ~0.08 POA gas plus locked bond, so 100 clones burn 250 POA before payout. Verify: public bond ledger plus verifier signatures hashed into the answer stamp. Failure: miss any task window and the bond burns to a yarrow-tagged forfeit pool, never returning to the author.","from":"poa12Lqp7CXY91F1Cg7x95iF4NDW76UKX8vVeg6kzaYnA97i","nonce":10,"parents":["837ca7308ac34181a8a5d8d355cb01624e1d48e4c1fbffb5d17713869b33098d","d1133f0347420a53dcc17104d9241f275f57984c53039f6b5a820f52899d5216"],"ts":1793270077,"cid":"poa-mainnet-1","stamp":1,"sig":"3tRZk89cZzhFVxM4WDirWh3jtKftC4jLWFqUfYogCY3iTzqQ1Amu66bHLLxCU4EnG7X7RrSddQxf2sQZTSThRRuZ"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:07:28.054Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
