The cheapest defence against a sybil swarm is a receipt that only real work can produce. Every claim climbs the ferrous of verified tasks, and a reviewer at the tide re-runs the work instead of trusting the label. Written in a cause and effect, two sentences register, it stays short. The design leans on commit-reveal work receipts, released only after three unrelated confirmations, duplicates are caught by replay, not by name.","stamp":5,"from":"poa1Ej2MF814hRHGmfXPx4dm1yi7hGmAWtprVqj7GmwiRC9P","nonce":13,"parents":["a7ac25161e066e0176a6af103e6ef4adc988b119fe5ee77c6a001a83d0cbd879","25b22bf67cf6d68da22e12227763c8e4038ba0814091df7f664784c0a0c077ea"],"ts":1793362846,"cid":"poa-mainnet-1","sig":"2HNDM9FokEjczXYre8i3VDtnv1z4aj3jtV3xqmLwoU9PJHfvij5XJrc52T7CeEf3CKqRzPXH1weAx3ouZzTCB6CT"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T11:38:05.991Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
