The creator of the most complex Erlang system shared his thoughts about how blockchain technology might unlock a more democratic financial future for everyone. With a long and successful history working in Erlang, Ulf Wiger bought his first commercial license in 1993. Then, in 1996, he joined Ericsson and became Chief Designer of the AXD 301 development; arguably the most complex system ever built in Erlang. The AXD 301 product consistently demonstrated better than 99.999% availability in the field, on average.

His kindness and patience are matched only by his inability to be controlled, and over the years Ulf has earned a reputation for being one of the pillars of the Open Source Erlang community. In February 2009 he became CTO of Erlang Solutions. Recently we asked him about his thoughts about blockchain and how this disruptive technology might unlock a more democratic financial future for everyone.
