Everyone has an opinion on how Blockchain will change business and society. Quite a few startups are working on their Blockchain-based products or services, and some of them are even using initial coin offerings (ICOs) as a funding vehicle. However, it’s hard to find good use cases that haven’t been solved already with more traditional technologies and business models.

To overcome this hurdle  I have created a simple framework that might help people to evaluate use cases and identify the most promising ones. There are many things to take into account when evaluating a Blockchain use case but there are few that are crucial, the others can be considered implementation details. We need to begin with the most important one: what class of problems Blockchain is designed to address.
