I'm more familiar with artificial intelligence and machine learning but not reading a lot on blockchain and cryptocurrency technology. I really have no idea of an innovative combination of both techs. It seems that blockchain is some sort of distributed ledger so that we have to rely less on middlemen. It seems that computing and programming are more necessary for blockchain rather than AI (disclaimer: limited knowledge in blockchain haha)
I want to democratize AI, Google and Facebook gain to much power with our Data.
Because of this we should take all our data to the blockchain and then create ML-models in a democratized way (everybody has access to the final models if you contributed your data)
