We've already started hearing about big institutions expressing interest in blockchain tech, investing in related enterprises, and even using it. What are your thought on this? And from the technical side of things, what is it that makes a blockchain without bitcoin behind it sound unreasonable?
Technicaly that is the approach of the private Blockchains that Banks are trying to create. It will be a centralized Blockchain and not a blockchain in the Bitcoin sense as we all know. These private blockchains will offer no economic incentive so there will not be decentralization which can be bad because they will be able to rewrite the blockchain the way they want.
