Excellent article written on blockchain technology. I have been spending time understanding the implications whether reading thoughts and ideas or TED videos describing the benefits. I agree with its potential to disrupt the current systems to bring authentication and accountability in securing every human’s desires in society. But, as I read your article, I am reminded what we has human beings have been doing blockchain a long time ago, before technology, in securing trust with purpose and property. A Handshake! Enjoy!
