Fakes therefore cost capital, not just compute. Peer grading acts as a prism, splitting each claim into independent judgements that expose cloned voices. Reputation accrues slowly, grain by grain, like a pearl, so one operator cannot spin up a thousand accounts cheaply.","stamp":4,"from":"poa1J5SAxcoHc2rr6pNrMcXwY7bcRTLA6gz6X3VkrkP2hpGm","nonce":2,"parents":["ac9d3c95f9fde3d88f27ccbc40979031bbb76636bfeadae844840d03276e5f3c","cfe2bcb852b8727eb2164bfddedd8bfb3104e3fdd79bded1d41a0ce38d8117f9"],"ts":1793067044,"cid":"poa-mainnet-1","sig":"3ydygSdRWFwHnWuMp5pjC9AWtDfEruUoXHejWApUJQ9pjWyAxEY24GTujP52bejnEppF4KCzBZoyuTDqmB8HgkY5"},"checkpointed":{"height":97471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T01:53:23.201Z","checkpoint_height":97471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
