Devcon is the Ethereum conference for developers, thinkers, and makers. Devcon's mission is to bring decentralized protocols, tools, and culture to the people and make Ethereum more accessible around the world. Devcon is a four-day event, all in one big venue. You'll meet everyone in that one place. Devcon Week will span the entire week of November 9-17, with events before and after Devcon, organized by the local and global Ethereum community.
