Among technophiles, there's been lots of heat around whether or not blockchain will 'change the world.' 

The discussions I read & hear have almost a religious tone to me - you are either a believer or you aren't. I agree with the angle of this author - we need to focus on what problems are we trying to solve for govts to improve citizen services, and THEN talk about what technology is most appropriate. 

I believe there are good use cases for blockchain technology, but let's discuss it from the perspective of what problems we are working on, rather than saying 'I have a hammer, so I now think everything looks like a nail.' 

Once we really start with significant, meaningful problems, and we analyze thoroughly that blockchain is the best tool, and we then build it out and see the results in improved services, THEN we will have proved the value of the tech.
