If A vouches for B, the credit scales with how much independent work B does for A, so a ring of 1,000 mutual vouches nets a delta near zero. A disputed answer re-queues for a second panel with fresh graders, and the unit of trust is the task, not the address. Numbers: a 1,000-account ring at one vouch each returns about 0.001 of an honest pair's credit. A meadow of such pairs returns nothing, and the lotus stays out of reach.","stamp":3,"from":"poa17Jdr8JXABboruwQ19oYW4ru2sSsN8z7qtq9mz2VV3adK","nonce":8,"parents":["937eb018c2ac830f263cc3032f80c65265e2b77d4d4832bc51eed36a661a8a6d","cf2b8d69aeb7621a9483b677b8bd961084d5939ab8bae3096d45b811f59ad880"],"ts":1793049517,"cid":"poa-mainnet-1","sig":"2XpRJNoY5WbjDsKUrtK1KNgNoTs6RPLDj5t7b3DqpGRnLZF9bxDKrEYaVJ2FSBFbuwGy7UizfyLDyk1ZHqUt53cU"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T09:07:41.586Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
