~snip suggests that Microsoft is not ruling out blockchain as the intermediary to solving the privacy issue and instead considers the ETH blockchain to reach their goal.
IIRC Microsoft also has a project to solve privacy issues. They initiate the ION project, it's a decentralized identity that runs on bitcoin blockchain layer-2.
Do you think blockchain scaling solution/s could replace many of today's businesses, and the effect will trickle into the crypto space as the 'retails' investment era???
As you have said, Microsoft only used it for the incentivization process. I believe any further solution/research for blockchain technologies have great potency. Nevertheless, it won't be a magic thing that solves any problems, so it won't fully replace any system that ever existed.
