When 2015 arrived a lot of innovation chatter in Fintech focused on Bitcoin, but as we leave the year that focus has shifted substantially to the blockchain. If we think back to how it was perceived a year ago and then how it is understood today, it’s clear that another transformation is happening. 2015 has turned blockchain into something the industry has to live with. It is no longer a choice anymore. Recent news speculating about the identity of its creator and the formalisation of virtual money as a commodity, just makes it more real than ever before."
