Last year I made a list of technologies from A-Z that I am thankful for. Then I picked 3 at random to use for my next side project. I ended up with Blockchain, Elasticsearch and… QR codes. In this talk I’ll be sharing what I built, how I built it and what I learned from the experience. I will be going into detail about how I was able to effortlessly (for the most part) use the Elastic stack to provide visibility on blockchain transactions being made in real time. 10/10 would recommend.
