I have no stake in this whatsoever, I just have some questions that maybe you (or somebody else) can answer, as I'm finding myself agreeing with the parent post. - What does blockchain have to do with HPC? What advantages does this give me versus current solutions? - If I was concerned of the privacy of my data, why would I put it on an unproven, public, immutable ledger? We all know what can happen when even minor bugs rear their heads in these types of applications. - Where does machine learning come into the equation? - Why would I want to use this rather than AWS/GCE/etc.? I guess really what I'm asking is, what problem is this solving? Just curious :)
