Similarly, I believe that Bitcoin is the first “killer app” of The Blockchain as email was the killer app for the beginning of the Internet. We are in the process of inventing eBay, Amazon and Google. My hunch is that The Blockchain will be to banking, law and accountancy as The Internet was to media, commerce and advertising. It will lower costs, disintermediate many layers of business and reduce friction. As we know, one person’s friction is another person’s revenue.
