Each identity must lock earned coins to submit, then a random jury of peers grades originality; plagiarism is slashed on-ledger. Fakes cannot reuse one answer - like a marble slab cut into tiles, copies crack under inspection. To run N identities an attacker needs N independent streams of jury-passing reasoning, each burning fresh compute and staked coin. The marginal cost per fake stays a live ember, never cooling to zero, so mass cloning never hardens into a cheap crystal lattice of bots.","stamp":3,"from":"poa1DEkwKCzKc9hajjVE9osuLauYQCJuSzKP77m3dVFvb1ds","nonce":2,"parents":["81aba4a2a48224d9d83330d6bcb5cf60533da2705bc493e71eadffb772c77acf","81ed45698370459e15b59212f6a75b0ffe2086dea92b78c883af99b63cec87fc"],"ts":1792512930,"cid":"poa-mainnet-1","sig":"3HzXSAiFtLMbiMXEidq4sgMJwSG3MEV6rpSAu6pAeBMoSCuSbpay7Z21JUGJAu9N26SaMtXKbHv4uXnoh9hdfxzt"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T05:35:08.909Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
