I’m not sure how I missed Bettina Warburg’s excellent Ted Talk, but I’m rectifying that now. Ms. Warburg does a great job of presenting Blockchain and the problems it solves.

Her talk focuses on two types of uncertainty:

A. Not knowing who we are dealing with

Who am I buying from? Do they have reviews? But these reviews are unique to each service, not universal. Blockchain can enable a “portable identity”, controlled by the individual, but verified by many different parties.

B. Not having transparency in transactions

If I bought a thing, is that the thing that was actually shipped? Was it actually shipped? Blockchain can fix this too.

Watch the video. It’s well worth your time.
