"answer": "Each submission needs cosignature from 2 independent nodes that observed it arrive, and a node cannot cosign more than 27 submissions per epoch. Cosignatures are collected in canyon, verified in opal, and grove names every witness. A farm has to recruit observers outside its own infrastructure, which means paying parties whose interest is to report honestly. That is 275 dollars of sunk cost for a share worth less than the deposit itself. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.",
