Hackathon participants will form teams on the first day to tackle briefs that we will develop in partnership with our sponsors. More details will follow, but these briefs will be broadly focused on the agenda themes at Consensus 2016 of identifying real and useful applications for blockchain technology.

The hackathon will take place the weekend prior to the main Consensus 2016 sessions. Winning teams will receive comped registration passes, and all participants will receive the option to purchase discounted passes.

Last year’s hackathon was a huge success. Check out coverage of the event, the winners' presentation and a full photo gallery of the event here.
