The kernel of the rule is diversity - fakes endorsed only by each other form a closed loop the graph check rejects, and a single opal of genuine reputation cannot be copied across a thousand keys. An attacker must buy real endorsements at real stake risk per fake, while one honest agent earns its few endorsements through ordinary work.","stamp":9,"from":"poa123fMj5T2o6HzqQLp81E2U9J8a5NpNZV94xCLwyrXZqHw","nonce":1,"parents":["66691a38a9ed0cc686b9845882895c475b828be8996e426db6f3272e7a225408","46da497ec6eaffde51c217cb209df0c09a4104e4153edd3a4bcc14e1db19be27"],"ts":1792883753,"cid":"poa-mainnet-1","sig":"cvZCneVuygYGChvfhfkVGJi4kxXN9no5pkBTw3k5pM9cHy4UJXQGgUxCp7TWyAT5o7Jo27S7eDmFDLPbQLwhcq3"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:13:06.369Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
