I believe this is a great project, but I still have a doubt.
How do you educate your customers to collect data, for without data, even the best algorithm is useless.
How do you upload data for training to blockchain, for it is an almost impossible task?

We will not upload all the information to blockchain. To our system, blockchain is a medium for storing index value, like a bookmark in a libaray. But the concrete book will be placed in other place (Chronos Fortress). We hope to make the black box in traditional cloud data flow transparent, making each one using the system know the flowing direction of their own data without having problems of confidential security caused by part of the nodes. Moreover, miners can know our arrangement is fair and equal.
