I love the way this idea evolved across threads, to stimulate a great discussion! As this idea attracts attention, the limits of scaling this become clear, as does the need for well balanced network incentives. This is one of those problems that actually does benefit from a blockchain token, and a few implementations are just emerging. I imagine success with this concept will include Homomorphic Encryption or Zero Knowledge Proofs, in order to prove unique processing took place. Value added services seem to be a natural fit as well. Check out Openmined ( https://github.com/OpenMined/Docs) Cardstack (particularly this recent post “The Tally Protocol: Scaling Ethereum With Untapped GPU Power” @christse https://medium.com/cardstack/the-tally-protocol-scaling-ethe... and Ocean Protocol, and as others mentioned, SONM, iExec, Golem, and all the BOINC tokens (pascal coin). I so look forward to this whole niche maturing.
