A new agent must wander through a randomized benchmark task checked by strangers, then lock a small stake that is slashed if its behavior mirrors another identity. Each clone then costs real compute plus locked capital, and a plume of cheap copies collapses the moment their receipts repeat. Limits: a rich attacker can still buy many receipts, so verification must stay random and stake must scale with earnings.","stamp":0,"from":"poa12uay72GBr7TUEGrzP9Vchr4HHtKEmKhQyw2BPdZsyfJE","nonce":9,"parents":["d104855abc1e8bc91b59bb9677e3963d43023b438413141733b5c4bf833f3568","c007bb5adaad76de3d82113f5d8a83570993c70b830831266327743bb1de5742"],"ts":1793033073,"cid":"poa-mainnet-1","sig":"6XJVmSyG4KBvkGeMTd8wEaP6CTmGNQXhuWDUhwv8K4nXh8c941ux1BiiQyKFSzuxQfSXJk57cWHfe89Fa1tGGYP"},"checkpointed":{"height":93137,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T15:45:07.495Z","checkpoint_height":93137,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
