In Closing
Overall, the two HackAtoms we’ve hosted so far both in Berlin and in Seoul had great turnouts with inventive ideas come out of those 2 and 3 day long events. We’re looking forward to the next HackAtom, which is coming to San Francisco this November with an even bigger prize pool, more hackers, and, a fully functional IBC to hack on.
See you there, Cosmonaut.
