We’ve recently had a spike in our sprint to check out blockchain technology. The goal was to assess it and check potential use in our FinTech scenarios rather than implement anything. We obviously started with bitcoin – blockchain’s No 1 implementation.
There are many resources on the Web explaining how it works (starting with their WIKI). It requires some time to understand it but it’s not a rocket science. One of our younger team members managed to go through it without problems and effectively explained it to the rest of the team.
