IC3 2019 Fall Retreat

Friday November 22, 2019 4 JPM Chase Metrotech Center, Brooklyn, NY 11245 5th Floor, Room 514

IC3 faculty, students, sponsors, and guests gathered at the IC3 Fall Retreat at the JP Morgan Metrotech Center to discuss the major technical challenges, issues and innovative solutions to widespread blockchain adoption. Researchers from CMU, Cornell, Cornell Tech, ETH Zurich, EPFL, UC Berkeley, UCL, UIUC, and the Technion were all present along with representatives of IC3's industry partners.

Prof. Andrew Miller, UIUC and IC3 Associate Director welcomes the retreat attendees before the start of the first session on Smart Contract Architectures (please see agenda below).

Attendees gathered for a group photo after the final session of the day.

There were 28 talks from faculty and students across the globe and a compelling Town Hall led by Prof. Andrew Miller (please see overview at bottom of the agenda).

Ample breaks were scheduled for follow up discussions and networking. The Retreat was capped off by a dinner at the nearby Kimoto Rooftop Restaurant and an after-party at the aptly named Endswell.

Please see the detailed agenda below.

Town Hall Session Overview: An open discussion forum led by Prof. Andrew Miller (IC3 Associate Director) to get feedback and input from our industry partners and faculty membership. The following topics are suggested to seed the conversation. Please ponder this beforehand and come with questions and comments at the ready!

1. Our tremendous research progree speaks for itself, (e.g., see our website), but let's review our grand challenge problems and goal setting. How shall we set our priorities and focus areas for the next year?

2. What are the most important upcoming problems for which the current progress and research directions are not yet addressing?

3. How are we doing at transitioning our research to practice, and what opportunities should we exploit to do this more? I will discuss an emerging plan, called "Blockchain as a Clinical Practice", or "Blockchain for Social Good", in which we take an active role in leading social benefit projects to deploy our research.
