Exploring the application of Blockchain in the industry: that was the 2nd Blockchain Hackathon Stuttgart!

New year – new Blockchain Hackathon.

The successfull format of last year’s Blockchain Hackathon, organized by bwcon and blockLAB Stuttgart went into its second round. On the weekend between 15 and 17 February, more than 150 hackers came together to elaborate visionary ideas under the motto: “converging the crypto universe into industrial IoT”. In 20 teams and with the support of about 20 mentors, they developed innovative concepts, business models and proof-of-concept implementations. Which innovative ideas could emerge when Blockchain technology meets digital infrastructure? How exactly could Blockchain technology drive innovations like AI or Robotics forward? These and many more questions were answered during the three days of the Blockchain Hackathon 2019.
For the first time, the Hackathon also marked the opening event of the Blockchain Stuttgart Week. This is one week of conferences held by experts, meetups and more events which offer both newbies and experts inspiring insight into the latest Blockchain topics.

The Stuttgart region is predestined to play a leading role in the intersection between blockchain technology and industrial applications. With its industry-oriented value creation structure, the local global players and hidden champions the region has a lot to offer. Accordingly, the hackathon has launched challenges in the fields of industry 4.0-IoT, mobility and finance.

A total of 15.000 euro prizes money was awarded in the categories “best visionary concept”, “best technical implementation”, “best business model”, “Hackathon challenges” and “audience prize”. The event was supported – among others – by Daimler AG, LBBW, targens, MHP and Alcatel Lucent.  In addition, two keynote contributes with great insights into Blockchain technology: Ikhlaq Sidhu, Founder and Chief Scientist of the Center for Entrepreneurship & Technology (SCET) in Berkeley give a speech about “Industrial application of Blockchain”, while Oliver Terbu from ConsenSys, uPort illustrated how to scale Decentralized Identities.
