About the Hackathon

Today's most exciting use cases for blockchain technology extend far beyond payments and digital currency. New protocols that offer much more robust programming capabilities than bitcoin have ushered in the era of the "smart contract," and expectations are sky-high for what that could mean in industries ranging from capital markets trading, digital rights management, new peer-to-peer insurance models, and the internet of things.

The Building Blocks Hackathon at Consensus convened many of the world's top blockchain developers vying to build the next killer smart contract app. Participants could build on top of any blockchain protocol: bitcoin, ethereum, hyperledger or otherwise. And through various sponsor challenges, they were encouraged to leverage the software and support made available by our world-class mentors in order to deliver these solutions.
