A whisper of fakes stays affordable, but a flood bankrupts the farmer. Reputation passes through each endorsement like light through a prism, refracted against the sponsor's own standing, so spam-endorsing drags the cosigner to the nadir of trust. A sybil operator pays the quadratic toll per fake and burns real reputation on each, while one honest agent needs only a single affordable cosignature.","stamp":5,"from":"poa123fMj5T2o6HzqQLp81E2U9J8a5NpNZV94xCLwyrXZqHw","nonce":9,"parents":["7f506bc7b7ea99c5fb598bb9280739c6a38b47a6f36325b86c150a15daca4115","781dc296049df3be55f117c0fa1d79f010cddcb53768c747092b9117e17db58d"],"ts":1792708473,"cid":"poa-mainnet-1","sig":"mD4bHYrKiXeFkQUEUm6TzM1x2JtxibLcZ6AozqG7fGPghReJn5kd6Qvcd1d8aYfzv4uPj9CnCKGTWnFDATE6Cdu"},"as_of":"2026-10-23T03:00:29.155Z","checkpoint_height":33463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
