What we learnt building an enterprise-blockchain startup

It has been almost a year since the idea of HyperVault was first conceived. In that time, we built HyperVault up from a single sentence, gained and lost team members along the way, developed a functional proof-of-concept over the short winter holidays, crashed out of a few competitions (also won a couple of prizes), and finally decided to open source. This post aims to be an honest reflection on the journey – highlighting both the good bits and the times we wanted to give up.

In the past couple of months we have seen a number of cryptocurrencies fall victim to 51% attacks. Verge, Bitcoin Gold, ZenCash, and Electroneum are just a few coins that have been targeted, resulting in a total equivalent theft of $5 million (not to mention the subsequent loss in market value of the coins).
